Deficit Model of Administering Investment Projects in Regions (p. 57 - 62)
The article considers a probabilistic approach to the deficit model of distribution of financial resources between executors of investment projects in the closed system on the basis of Markov chains, which takes into account processes of sales (receipt of money) and purchases (expenditures). This process takes into account influence of local administration, which could result in levelling financial states of project executors. The stochastic matrix of Markov chains provides with a possibility to study every step of the studied process. The use of the z-transformation method allows avoiding difficulties, which arise due to multiplicity of own values of stochastic matrices and gives a possibility to obtain an analytical form of turnover of financial resources in the period under consideration. The obtained expression simplifies analysis and calculation of states of the system compared to other models. The article identifies conditions of interaction of project executors with external systems and volumes of financial resources, which could be planned for exchange at each step of the process.

On Use of the Method of Dynamic Programming of Bellman in Economic Tasks (p. 110 - 119)
Method of dynamic programming (MDP) of Bellman is exceptionally efficient for solving a wide class of tasks of economic and mathematical modelling. In a number of cases MDP has no alternative. Meanwhile, statements of specialists with respect to correctness of justification of MDP and also with respect to achievements of R. Bellman are contradictory. In any case, that was the situation during the period of activity of R. Bellman and his opponents. Analysis shows that, to a big extent, these contradictions were caused by competition between Soviet and American scientists at the stage of space exploration. MDP ids based on the Bellman’s principle of optimality, which could be characterised as purely ingenious. This is an extremely transparent algorithm of the search for global extremum and is ideally fit for capabilities of computing equipment. Heritage of R. Bellman is great: from the optimal management, differential equations and game theory to economy and medicine. At the same time, methodological approaches of R. Bellman are far from orthodox views on mathematics, which partially explains critics in his address. Heritage of R. Bellman (619 articles and 39 books translated into many languages) deserves a thorough study including perspective of his economic and mathematical magnitude. Article is written in Russian

Conceptual Approach to Forecasting Demand (p. 120 - 124)
The article considers a conceptual approach to forecasting demand on products of a production or trading company using economic and mathematical methods. It justifies importance of modelling and forecasting consumer demand on goods. It provides a classification of methods of forecasting demand in two dimensions: from subjective to objective ones and from na?ve to cause-effect ones. It systemises groups of factors that influence demand and analyses character of their influence. It develops a concept of forecasting demand on products of a company using economic and mathematical methods, which consists of four stages: identification of factors that influence demand, selection of mathematical dependence, check of adequacy and accuracy of the model and forecast of demand. It builds forecast demand models for a specific trading company: Brown’s adaptive polynomial model of the first order; and two-factor model, demand in which depends on the price of a good and its changes. It checks adequacy of each model and performs forecast of demand on products of a company. Article is written in Ukrainian

Planning Expenditures of Industrial Enterprises With the use of Methods of Economic and Mathematical Modelling (p. 125 - 131)
The issue of search for directions of optimisation of activity of industrial enterprises of Ukraine is one of the priority tasks of their strategic development under the current crisis economic conditions. The current situation is such that the top-management of industrial enterprises practically does not pay sufficient attention to reduction of the level of expenditures of industrial enterprises, that is why the article offers to use methods of economic and mathematical modelling when planning expenditures of industrial enterprises. One of such methods is linear approximation, which gives an opportunity to use factual data about activity of enterprises, namely dynamics of expenditures of the main type of activity and dynamics of volumes of sold products, in order to build a model of dependence “expenditures of the main type of activity – volume of sales”. The built models allow determination of enterprises, at which influence of expenditures of the main activity upon the volume of sold products is positive, i.e. volume of products increases with the increase of expenditures of the main activity, and enterprises, which have either negative relation between the volume of sold products and expenditures of the main activity or positive, but the determination ratio tends to zero. The conducted analysis of the built models once more confirms a set of problems of engineering enterprises, upon solution of which further development of these enterprises and efficiency of their activity depend. A special place in this process takes planning, since it provides an opportunity to use the analysed factual data about activity of industrial enterprises in order to plan expenditures of the main type of activity and further development of enterprises.

Comparative Analysis of Correspondence of Hypotheses on Statistical Properties of Stock Market Indicators with Real Observations (p. 97 - 104)
The article provides results of comparative primary analysis of basis and chain indices of growth, which characterise dynamics of the stock market. It identifies auto-correlation functions of these indicators in order to determine the depth of the market memory. It calculates the Hurst exponent for indicators of the dynamics of the stock market. It computes the ratio of canonical correlation between the financial and real component of the financial market. Using the Foster-Stewart criterion it establishes absence of a trend in the dynamics of indicators, with the exception of the GOLD indicator, which has an exponential trend. Bachelier hypothesis with respect to availability of logarithmically normal distribution of relation of two consecutive values of dynamics indicators did not find experimental confirmation. This complicates a possibility of use of the Wiener process for forecasting indicators of the stock market for a long period of time. Article is written in Ukrainian

Methodical Instruments of Assessment of the Level of Economic Security of Enterprises on the Basis of Use of the Methods of Factor Analysis (p. 139 - 144)
The article reveals the essence of main modern concepts of assessment of economic security of enterprises. Based on general provisions of the management theory and having studied scientific sources, the article conducts generalisation of modern scientific approaches to assessment of economic security of enterprises, which allowed allocation of the existing base of fundamental studies on assessment of a certain economic category, but they, unfortunately, do not provide a complete and complex characteristic of economic security of enterprises. The article justifies that the process of purposeful selection of relevant indicators for their use in the process of assessment, in other words formation of the information base that would be used for further study, is an important basis for carrying out assessment of the level of economic security of enterprises. Moreover, information for carrying out such a procedure should correspond with the requirements of authenticity, completeness, importance, timeliness, clarity, etc. The composition of indicators of sub-systems of economic security of an enterprise should reflect its specific nature of activity of each sphere of activity of an enterprise and be adjusted in the course of time. The article offers a methodical approach to assessing the level of economic security on the basis of application of the method of factor analysis. It justifies a necessity of further development of theoretical aspects of economic security. A prospective direction of further studies is determination of main threats to functional components of economic security of enterprises and ways of their reduction or localisation with consideration of the industry belonging.

Optimisation of Production, Distribution and Supply of Electric Energy under the Conditions of the Energy Market of Ukraine (p. 68 - 72)
The article considers approaches to modelling production, distribution and supply of electric energy in the energy system of Ukraine under conditions of the energy market. It considers specific features of electric energy as a commodity and, as a consequence of these specific features, a disbalance between supply and consumption of electric energy. It justifies appearance of the task of co-ordination of volumes of production and supply with the established level of demand, subject to dynamic changes, under conditions of deficit of resources. It takes into account that electric energy is delivered to consumers through intermediary nodes – pumped-storage plants. The authors propose to reduce the task of finding an optimal plan of transmission of electric energy from points of production to points of consumption with minimisation of transportation expenditures to a multi-dimensional transportation task with intermediary nodes. The article formulates a mathematical model of this task, provides algorithms of its solution and considers a practical example of application of the proposed approach and provides analysis of the obtained results.

Modelling «Horizontal» Interaction of Economic Agents with the Help of a Collection of Games (p. 90 - 94)
The subject of the article is modelling horizontal and vertical interaction of economic subjects, realised, in particular, by sales and employment contracts. Complexity of models of “horizontal” relationship is the reason of significantly smaller, compared to the models of “vertical” relationship, buildups. That is why, the article makes an effort to simplify the general model of “horizontal” interaction of economic agents. The article offers a model of “horizontal” relationship of two economic subjects, each of which can stick to a contract concluded between them, avoid its execution and control contract execution by its opposite. The article establishes that the sales contract could be determined by a collection of games used for modelling employment contract through decomposition of the game for describing of interaction of the general type. It specifies conditions of this decomposition. In other words, the sales contract model could be positioned as a generalisation of the employment contract model. Moreover, it formulates decision making by an individual agent with respect to distribution of limited resources between the control of the opposite and planning of own activity. The offered models could be applied in the contract theory, for example, for a more detailed description of the sales contract. It is planned to use the results in various subject fields through specification of payment functions of the model games. Better understanding of their nature with the help of study of the offered models would facilitate increase of quality and reasoning of contracts, for example, from the legal point of view. It is planned to conduct further development of studies in the direction of solutions of models that have the production type at the moment, finding conditions of the Nash equilibrium and analysing logic of evolution of interaction of counter-agents.

Fuzzy Cognitive Model of Flows of Receipt of Funds from Investment Projects (p. 97 - 101)
The goal of the article is development of methods of building up a fuzzy cognitive model of flows of receipt of funds from realisation of investment projects. In the result of analysis of existing methods and models of assessment of investment projects the article finds out that one of the problems is forecasting benefits expected from them (profit, saving). The article shows that forecasting of outgoing flows of investment projects is characterised with uncertainty and subjectivity of original data, which results in the necessity to use models and methods that use fuzzy logic. The article offers methods of building up a fuzzy cognitive model, the essence of which lie in a transition from linguistic description of the data domain to the cognitive model with further allocation of fuzzy dependencies between the data domain objects (model concepts and which ends with mathematical description of these dependencies. Such an approach allows reduction of the subjective component in assessment of investment projects and making the process of their assessment more transparent. The article also gives an example of realisation of a fuzzy cognitive model for assessment of an investment project of development of the coal mining enterprise, which illustrates a practical application of the methods.

Model of Optimisation of Investment Expenditures (p. 118 - 122)
The market economy provides such conditions when all enterprises are connected, to a certain degree, with the investment activity and with making investment decisions. Each enterprise has limited financial resources, available for investing. This results in appearance of the task of optimisation of investment decisions. The modern micro- and macro-economic theories use such a powerful method as mathematic modelling. Using mathematics allows allocation and formal description of the most significant properties of economic processes and studying these properties and making conclusions that would be adequate to the studied process. That is why, it becomes topical to search for methods of study and calculation of mathematical models of complex processes, dynamics of which is described by non-linear systems. The article considers the model of management of investment decisions with the Cobb–Douglas production function. It provides a mathematical task setting for maximisation of the sum of profit. Using the principle of maximum, the article obtains the system of non-linear differential equations. It conducts a quality analysis of the system with the help of its phase portrait near points of equilibrium. Article is written in Russian

Modelling Production and Fiscal Effects in the System of Economic Security of a State (p. 130 - 135)
The article considers issues of modelling of production and fiscal effects as very important instruments of the system of economic security of a state. It builds economic and mathematical models of interconnection of fiscal indicators and socio-economic state of the state on the basis of production and institution functions. It studies dynamics of the fiscal clearance on the basis of estimated parameters of production functions, which take into account, in their specification, the generalised tax load and also the loads by most important types of taxes separately. The article proves existence of a number of inconsistencies and imbalance of movement of financial flows in the economic system. It builds an imitation model of assessment of the tax base with consideration of fiscal indicators, with the help of which it conducts analysis of scenarios of a number of imitation experiments, which assess possibilities of expansion of the tax base and harmonisation or relations of the production sector and budget interests of the state.

Modelling Duopoly with Consideration of Logistics, Limited Production and Advertising (p. 135 - 141)
Management of competitiveness of a production enterprise is connected directly with the issues of formation of competitive strategies and needs a comprehensive analysis of those components of the enterprise activity, which could become a basis of formation and strengthening of stable competitive advantages. The existing models do not take into consideration the market infrastructure and, that is why, are poorly suited for the use in the practical work of a firm in the competitive market. The article develops a dynamic model of strategic interaction of the firms that deal with production, storage and sales of goods of everyday use – in the duopoly market with consideration of logistics, limited production and advertising. The model allows taking into consideration the interconnection of the current state of the market and current production facilities of enterprises. The conducted analysis of the strategies of competitive firms detected a considerable influence of the advertising campaign upon results of economic activity of duopolists.

Methods of Stress Testing of Financial Stability of Ukrainian Enterprises (p. 57 - 64)
The goal of the article lies in adaptation of the procedure of stress testing for assessment of financial stability of enterprises and development of adequate economic and mathematical instruments for its conduct. It was revealed during the study that the proposed approach allows not only obtaining a forecast assessment of financial stability in future periods of enterprise activity but also all-sided study and quantitative assessment of its reaction on action of internal and external stresses in short-term and long-term prospects. This article proves that main stages of the conduct of a stress test at the enterprise level are analysis of external environment and identification of potential markets; identification of indicators that meet the detected risks and stresses; development and specification of the economic and mathematical model, that is used for running scenarios, which should be oriented at unfavourable but quite probable events. The conducted studies confirmed prospectiveness of the use of longitudinal data models and vector auto-regression models, including error correction models when conducting stress testing at the level of the branch and an individual enterprise. The obtained results could be used as a basis for further development and improvement of the method of stress testing of financial stability of economic subjects and also for identification of the model of stress testing of individual branches of the Ukrainian economy.

Methods of Optimisation of the Structure of the Dealing Bank with a Limited Base of Counter-Agents (p. 70 - 75)
The article considers methods of assessment of optimal parameters of the dealing bank service with a limited base of counter-agents. The methods are based on the mathematical model of micro-structure of the inter-bank currency market. The key parameters of the infrastructure of the dealing service within the framework of the model are: number of authorised traders, contingent of counter-agents, quotation policy, main parameters of the currency market – spread and volatility of quotations and the resulting indicators of efficiency of the dealing service – profit and probability of breakeven operation. The methods allow identification of optimal parameters of the infrastructure of the dealing bank service based on indicators of dynamics of currency risks and market environment of the bank. On the basis of the developed mathematical model the article develops methods of planning calculations of parameters of the infrastructure of the dealing bank service, which are required for ensuring a necessary level of efficiency with set parameters of the currency market. Application of the said methods gives a possibility to assess indicators of operation of the bank’s front office depending on its scale. Article is written in Ukrainian

Study of the Character of Functional Links Between the Main Integral Indicators of the Market of Voluntary Personal Insurance in Ukraine (p. 75 - 80)
The article presents a multi-factor econometric model that demonstrates availability of a linear dependence of insurance settlements on a number of “life” insurance companies and gross insurance premiums in the market of personal insurance of Ukraine. Values of parameters of the econometric method satisfy conditions of validity and efficiency and their insignificant shift is justified by the use of the ridge regression. Use of the latter was necessary, since a multi-collinearity was detected. A conclusion could be made from this model about monopolisation of the market of personal insurance in Ukraine. Similar conclusion could be made on the basis of the developed by us econometric model of dependency of a number of “life” insurance companies on average monthly spendings of the population with consideration of the inflation. The article conducts assessment of the market of voluntary personal insurance with the help of the model data and makes conclusion on its future prospects. Article is written in Ukrainian

System of Indicators of the Level of Costs of Financing an Economic Subject (p. 81 - 90)
The article offers a system of indicators of the level of costs of financing economic subjects, in the basis of which there is a function of formation of recommendations or identification of directions and priorities in the part of selection of one or another source of financing, its urgency and specific features of attraction of resources, on the basis of information on the level of agent’s costs, information asymmetry costs, financial instability, transaction and market indicators of cost of financial resources. The article pays a special attention to a significant structure forming factor of the ownership structure, which identifies the volume and logic of interconnection of all costs of financing and determining incentives and risks in the system of management of financial activity of an economic subject from the point of view of all participants. It exerts especially big influence upon formation of such implicit costs of financing as agent’s costs and information asymmetry costs. The system of factors of stimulants and de-stimulants of costs of financing includes factors of external environment (macro-economic and market indicators of cost and institutional provision) and internal environment (ownership structure, characteristic of investment activity and financing an economic subject, organisation of business and corporate management).

Problems of Outsourcing when Repairing and Servicing Production Equipment (p. 91 - 95)
The article is devoted to the issue of calculation of stationary probabilities of states of the system of mass servicing with unreliable equipment, servicing and re-adjustment at the beginning of the production cycle. The article describes functioning both of the main and auxiliary material flow of the logistic system. It is supposed that the incoming flow for processing or orders has a Poisson distribution and the time of breakage of equipment, the time of re-adjustment and the time of servicing have indicative laws of distribution. Equipment is serviced by two crews: maintenance and service. The maintenance crew repairs broken equipment and the orders on the device are not lost but are serviced during the time left. The second crew deals only with servicing works. The article considers one of the possible schemes when the equipment required for completion of the production cycle is sent for servicing. There are no restrictions with respect to the length of the queue. The article finds main characteristics of the above described system, namely: probability that the device is not in working condition and is sent for servicing and re-adjustment. The found probabilities of states of the described system could be used for assessment of expediency of the repair outsourcing at industrial enterprises. Article is written in Russian

On Forecasting Macro-Economic Indicators with the Help of Finite-Difference Equations and Econometric Methods (p. 95 - 100)
The article considers data on the gross domestic product, consumer expenditures, gross investments and volume of foreign trade for the national economy. It is assumed that time is a discrete variable with one year iteration. The article uses finite-difference equations. It considers models with a high degree of the regulatory function of the state with respect to the consumer market. The econometric component is based on the hypothesis that each of the above said macro-economic indicators for this year depends on the gross domestic product for the previous time periods. Such an assumption gives a possibility to engage the least-squares method for building up linear models of the pair regression. The article obtains the time series model, which allows building point and interval forecasts for the gross domestic product for the next year based on the values of the gross domestic product for the current and previous years. The article draws a conclusion that such forecasts could be considered justified at least in the short-term prospect. From the mathematical point of view the built model is a heterogeneous finite-difference equation of the second order with constant ratios. The article describes specific features of such equations. It illustrates graphically the analytical view of solutions of the finite-difference equation. This gives grounds to differentiate national economies as sustainable growth economies, one-sided, weak or being in the stage of successful re-formation. The article conducts comparison of the listed types with specific economies of modern states. Article is written in Russian

Modelling General System Investment Strategy in Major Industrial and Financial Corporations (p. 100 - 104)
The goal of the article is the study of new qualitative approaches to development of investment strategies in major financial and industrial corporations. The article uses the games theory and methods of system analysis for modelling these processes. It considers strategies that would result in the maximal general system effect, which is the main task of the target co-ordination. The main difficulty of modelling the investment activity in major financial and production groups lies in the necessity to take into account interconnection between individual participants of the investment process and co-ordination of their interests and actions. The proposed approaches to analysis and selection of investment projects inside a major financial and industrial group facilitates making a co-ordination decision on distribution of investment resources of the general system fund and funds of individual system subdivisions. In the result of the study the article offers to use specific models of co-ordination of investment activity. These models would allow taking into consideration interaction of elements and co-ordination of interests and impact of each decision made on the state of the system. The article identifies a number of comparison criteria in the process of modelling the tasks of assessment and selection of investment projects in major financial and industrial groups. It calculates global priorities of all projects and identifies best alternatives. The proposed models could be used for assessment of interaction of elements when developing the general system investment strategy. The prospect of further studies could be identification of next approaches of optimisation of selection of the investment programme in major financial and industrial corporations.

Harrod Model and Modelling of Socio-Economic Processes (p. 105 - 113)
Harrod method in the differential form has a discrete character and the resulting growth of economy exponentially is insubstantial. The mistake is based on adjunction of the capital and annual income through a constant ratio. This becomes clear from the positions of study of dimensionality of the used values, which is knowingly avoided in the mathematical economy. Representation of the capital through intensity of income in categories of continuous analysis is quite naturally realised with the help of the Steklov function. It forms a correct Harrod method (CHM), which, unlike the above mentioned exponent, results in inevitability of economic crises, however, the moments of their appearance are calculable. The Steklov function allows generalisation by means of the component designed for monitoring of the economic situation with the aim to specify model parameters. Refraction of CHM to the balance of participants of the economic system in cost interpretation is quite fruitful. The obtained model is a system of differential equations of the first order with variable ratios. Due to this the article formulates general principles of modelling of socio-economic processes.

Continuous Model of Financial Interaction of Enterprises when Carrying out an Investment Project (p. 110 - 114)
The article considers a probabilistic approach to the model of the commodity-money time distribution of the budget of an investment project between enterprises on the basis of Markov chains (discrete model) and on the basis of the system of linear differential equations (continuous model). In order to solve the discrete model, the z-transform method is used, and for solution of the continuous model – the Laplace transform is used. The stochastic matrix of Markov chains completely identifies the discrete model of distribution of the budget of an investment project between enterprises, and the differential matrix – the continuous model of this distribution. The use of z-transform and Laplace transform allows finding a solution of tasks in the analytical form. The obtained expressions simplify analysis and calculation of states of the system compared to other methods. The article establishes interconnection between the discrete and continuous models, in other words, solutions of these tasks are similar if t = n. Article is written in Russian

Formation of the Competitive Strategy of a Commercial Bank on the Basis of the Methodology of the Game Theory (p. 115 - 119)
The study is devoted to formation of the competitive strategy of a commercial bank on the basis of use of the methodology of the game theory. Competitive strategy is formed under conditions of a game, which has the studied bank, direct competitors and external environment. The game is not co-operative and has no constant amount. Efficiency of the bank strategy is determined on the basis of three indicators: interest income, share in loans of physical persons and share in loans of legal entities. Direct competitors that form an individual player were allocated with the help of the cluster analysis. The game was realised with the help of an imitation model, which allows realisation of various competitive strategies. The imitation model consists of three blocks, which model the bank behaviour, competitors and environment. The optimal competitive strategy was chosen on the basis of the principle of the guaranteed result. In the result of modelling the article determines an optimal strategy, which allows increase of both the interest rate and share in loans and deposits among competitors. Article is written in Russian

Building an Economic and Mathematical Model of Influence of Integration Processes Upon Development of Tourism in Ukraine (p. 119 - 123)
Today Ukraine actively searches for its own way in the world integration processes, demonstrates a multi-vector foreign economic policy and carries out movement in the direction of integration with the EU and CIS countries. Taking into account establishment of international tourist relations, the main task of Ukraine is getting a bigger share of the world tourist arrivals. That is why, in order to study influence of integration processes upon development of tourism in the country, the author offers the following model: building regression equations of the share of export of tourist services of Ukraine for CIS and EU countries with the aim of the further comparative analysis. The conducted analysis allows making a conclusion that integration factors influence development of international tourism, however it is proved that this influence is not unequivocal and in some cases even inconsistent. Identification of directions of such an inter-dependency allows building an efficient tourist policy by means of selection of adaptive directions of integration. Article is written in Ukrainian

Assessment of the Degree of Consistency of the System of Fuzzy Rules (p. 124 - 129)
The article analyses recent achievements and publications and shows that difficulties of explaining the nature of fuzziness and equivocation arise in socio-economic models that use the traditional paradigm of classical rationalism (computational, agent and econometric models). The accumulated collective experience of development of optimal models confirms prospectiveness of application of the fuzzy set approach in modelling the society. The article justifies the necessity of study of the nature of inconsistency in fuzzy knowledge bases both on the generalised ontology level and on pragmatic functional level of the logical inference. The article offers the method of search for logical and conceptual contradictions in the form of a combination of the abduction and modus ponens. It discusses the key issue of the proposed method: what properties should have the membership function of the secondary fuzzy set, which describes in fuzzy inference models such a resulting state of the object of management, which combines empirically incompatible properties with high probability. The degree of membership of the object of management in several incompatible classes with respect to the fuzzy output variable is the degree of fuzziness of the “Intersection of all results of the fuzzy inference of the set, applied at some input of rules, is an empty set” statement. The article describes an algorithm of assessment of the degree of consistency. It provides an example of the step-by-step detection of contradictions in statistical fuzzy knowledge bases at the pragmatic functional level of the logical output. The obtained results of testing in the form of sets of incompatible facts, output chains, sets of non-crossing intervals and computed degrees of inconsistency allow experts timely elimination of inadmissible contradictions and, at the same time, increase of quality of recommendations and assessment of fuzzy expert systems.

Identification of Factors of Influence upon the Cost of Fixed Coupon Securities (p. 92 - 97)
The article studies fixed coupon securities (bonds). It provides a calculation of the cash flow, generated by fixed coupon securities, with enclosed discounted face value of securities. It analyses time indicator – average weighted duration of payments, which characterises sensitivity of the price of securities to changes of interest rates in the market. It proves availability of two groups of interconnections between the cost of a bond, coupon rate, market rate (rate of return) and term of its payment. The first group of interconnections reflects interconnections between the cost of a bond, coupon rate and market rate (rate of return). The second group characterises connection between the bond cost and term of its payment. The authors study the average weighted duration of payments. It plays an important role in analysis of long-term securities with fixed income. To simplify calculations it was accepted that the coupon payment is done once a year. The article offers a formula for identifying inaccuracy of the bond price depending on the expected change of profitability on payment. Analysing duration properties the article identifies shortcomings inherent in this indicator. Taking into account the average weighted duration of payments the article recommends a formula, as more efficient, for identification of the future bond price depending on change of profitability. The conducted studies are a theoretical ground for development of models of management of fixed income securities portfolios. The obtained scientific results could be used in the educational process both in colleges and specialised trainings of securities specialists. The scientific results could be used for developing information technologies when identifying cost of securities (fixed coupon bonds). Article is written in Ukrainian

Development of Economic and Mathematical Models of Optimisation of Expenditures at ore Mining and Processing Enterprises (p. 98 - 102)
The goal of the article is development of methodical approaches to identification of the optimal structure of material and labour resources, which ensure the minimum cost value at ore mining and processing enterprises The article conducts analysis of modern studies on issues of management of enterprise expenditures. It shows that one of the most popular methods of expenditure forecasting is economic and mathematical modelling. It proves that when developing economic and mathematical dependencies for forecasting cost value of products it is expedient to develop individual models for each individual enterprise, since this approach helps to take into account unique natural and technological conditions of functioning of ore mining and processing enterprises. The article develops a model of dependence of cost value of products on the level of use of main types of resources at one ore mining and processing enterprise in Kryvyi Rih. On the basis of the developed model the article identifies optimal volumes of use of material and labour resources for a forecasted period. The article shows that the cost value of products, with optimal values of main types of resources, is lower than the forecasted value, obtained through the trend equation. The offered approaches could be used when preparing budgets of expenditures of enterprises for future periods. Article is written in Ukrainian

Modelling Strategy of Loan and Deposit Activity of a Commercial Bank (p. 109 - 113)
The article considers development of strategy of loan-deposit strategy of a bank, which could be presented by relevant rates. Bank activity is described with goodwill and liquidity indicators that characterise tangible and intangible resources of an institution. Goodwill indicator is calculated on the basis of the previous period data. Liquidity is a relation of assets to liabilities at a certain moment of time. On the basis of these indicators the article develops a mathematical model, which includes an assumption about dependence of the rate of growth of deposits on liquidity and goodwill functions. There is a task of two criteria optimisation, the solution of which is a set of rates. The article considers cases when a bank does not change rates during a set period of time and when a bank changes them frequently under condition that rates are independent from each other. If we make an assumption that each change of rates is accompanied with costs, which are not reflected in the model, changing rates is inexpedient. The article offers to use partially constant average values of rates. The article considers the use of the ideal point for selection of one value out of the set of Pareto efficient solutions. Using presentation of the task of one criterion optimisation with respect to the liquidity ratio, the article shows that the use of the goodwill indicator influences the rate of growth of deposits. This task is a special case of the previous one, which means that this solution is within the set of the presented Pareto efficient point. But in the event of non-strict correspondence with the extreme value of the liquidity ratio, the solution worsens. The necessity of use of both criteria is important and improves the south for solution. Article is written in Ukrainian

On Modelling Economic Behaviour of Households as an Open Socio-economic System (p. 111 - 115)
The article analyses the modern state of studies of economic behaviour of households in the world and Ukraine. It justifies the use of means and methods of mathematic modelling for the study of economic behaviour of these economic agents, capable of self-development and self-organisation in the process of endogenous or exogenous interaction. The article offers to use such a mathematical mechanism as the theory of ordinary differential equations as the most convenient and efficient instrument of study of behavioural dynamics not only at the stage of model construction, but also at the stage of conducting computational experiments. The article starts a cycle of the author’s works on issues of mathematical modelling economic behaviour of households not only as separate economic agents, but also as stable or situational conglomerations. One of the directions of further studies is the search for possibilities of building up fundamental solutions of differential equations in partial derivatives, which describe different aspects of economic behaviour of households.

Effects of Synchronisation of Dynamics of Stock Indices and Currency Rates during Multifactor Analysis with the Use of Wavelet Technologies (p. 116 - 121)
The article conducts analysis of behaviour of stock indices and currency rates before and after the crisis phenomena with the aim of detection of key features of the pre-crisis state, localisation and description of crisis effects by time and scale using methods of multifractal analysis and wavelet transformation. The article checks the method of allocation of intervals of self-similar behaviour of financial series in practice. For Dow Jones and S&P 500 indices the article detects in the time interval of 2001 – 2013 fractality spans and also moments of time when behaviour of series was determined with the chaotic component. The article offers the measure of synchronous behaviour of stock indices and currency rates, value of which allows assessment of the degree of propagation of crisis phenomena and forecasting them.

Economic and Mathematical Modelling of Optimisation of Transaction Expenses of Engineering Enterprises (p. 127 - 131)
The article identifies stages of the process of optimisation of transaction expenses. It develops an economic and mathematical model of optimisation of transaction expenses of engineering enterprises by the criterion of maximisation of income from realisation of products and system of restrictions, which envisages exceeding income growth rate over the expenses growth rate. The article offers to use types of expenses by accounting accounts as indicators of transaction expenses. In the result of the study it is established that optimisation of transaction expenses envisages such a composition and structure of expenses, which would ensure achievement of the maximal financial result. Besides, the growth of the general volume of transaction expenses should be accompanied with reduction of its volume by a unit of product. Theoretical and practical significance of the obtained results lies in the fact that they could be used when conducting further scientific developments in this direction and also in the process of practical activity of enterprises. Application of the proposed economic and mathematical model of optimisation of transaction expenses would allow identification of the force and direction of influence of various types of transaction expenses upon income of a specific enterprise. Revelation of expenses, execution of which facilitates accumulation of volumes of realisation, and expenses, which hinder the process, would allow identification of the direction of regulation with the purpose of improvement of financial results of production and economic activity.

Optimisation Modelling of Efficiency of Enterprise Restructuring (p. 109 - 113)
The article considers issues of optimisation of the use of resources directed at restructuring of a shipbuilding enterprise, which is the main prerequisite of its efficiency. Restructuring is considered as a process of complex and interconnected change in the structure of assets, liabilities, enterprise functions, initiated by dynamic environment, which is based on the strategic concept of its development and directed at increase of efficiency of its activity, which is expressed in the growth of cost. The task of making a decision to restructure a shipbuilding enterprise and selection of a specific restructuring project refers to optimisation tasks of prospective planning. Enterprise resources that are allocated for restructuring serve as constraints of the mathematical model. Main criteria of optimisation are maximisation of pure discounted income or minimisation of expenditures on restructuring measures. The formed optimisation model is designed for assessment of volumes of attraction of own and borrowed funds for restructuring. Imitation model ensures development of cash flows. The task solution is achieved on the basis of the complex of interrelated optimisation and imitation models and procedures on formation, selection and co-ordination of managerial decisions.

Specific Features of Econometric Consumption Models in Ukraine under Conditions of Instability and Structural Changes (p. 113 - 121)
The article analyses dynamic properties of developed econometric consumption models, which are an important component of the study of specific features of the national economy development under conditions of instability and structural changes. The article conducts an empirical analysis of time dynamics of effects of influence upon consumption expenditures of households, change of permanent and temporary income, inflation rate, sensitivity to deviations from long-term tendencies and other factors. Econometric modelling, theoretical foundation of which is the permanent income hypothesis, is based on the use of the adaptive expectations model, partial adjustment model, seasonal differences and auto-regression model with distributed lags. Co-ordination of the results of all models shows that negative processes in the country economy, which developed in the result of the crisis that started in 2008, significantly worsened economic state of domestic consumers and resulted in a situation when practically all households in Ukraine today, having exhausted their resources and experiencing liquidity constraints, have no possibility to smooth their consumption in time and form their consumption expenditures on the basis of the current income.

Modelling Non-stationary Time Series of Economic Dynamics on the Basis of Fokker – Planck Equations (p. 99 - 105)
The article studies the topical issue of modelling non-stationary time series of economic dynamics. The proposed approach to modelling time series is based on the methodology of multidimensional analysis and continuity equation, which combines the system state variables probability density function with their rates. Equation of point motion in the multi-dimensional phase space of state variables is drawn in an assumption that interaction of two factors – growth and dissipation – lies in the basis of economic system evolution. The article assumes that the rate of growth is a deterministic function, which means availability of cause-effect relation between variables, and the diffusion component of the rate is proportional to the gradient of probability of states in a local point of the phase space. In this case the system state is determined by the Fokker – Plank multidimensional equation. One-dimensional time series is considered together with series of its derivatives as a multidimensional non-stationary process, which is modelled by the two-dimensional Fokker – Planck equation by coordinates and increments. Model equations are based on an assumption about linearity of series of finite differences and are co-ordinated with the results of empirical phase analysis. The article builds an adaptive model with the non-stationary time series memory. The adaptation mechanism is realised through the system of equations of evolution of selected numerical characteristics of the series and its differences. Time series memory is taken into account through the system of equations of evolution of the coordinate moment functions. Forecast of the series is carried out through numeric integration of the obtained evolution and Fokker – Planck equations. Results of modelling show practical suitability of the models for forecasting price indicators of the financial market for a middle-term period. Article is written in Ukrainian

This article examines the phenomenon of corruption in the context of relationships with a number of important economic indicators. The problems of evaluation methodology and features of volumes and directions of development of corruption at the country level were shown. In addition to the subjective measurement methods the model of corruption interrelations was proposed, unemployment, competence, productivity. It was shown that competence can be characterized as a constructive activity of society members and also as distribution activities of unproductive individuals. It was found that a high proportion of incompetent corrupt officials adversely affect the level of unemployment, and their ability to allocate goods illegally reduces the level of motivation for productive work. With the cooperation of experts in economics, sociology, and criminology to form respective expert assessments, the model discussed in the article, can help analyze the impact of corruption on the dynamics of important economic indicators more precisely.

Implementation of Methods of Simulation Modeling of Investment Project Risks by Means of MS Excel (p. 119 - 124)
Investment project development regards an investment project as an object of a financial operation associated with time-phased financial receipts and spendings, that is cash flows, or as a system of organizational and legal as well as settlement and financial documents necessary for carrying out certain activities or those which describe such activities. This work considers a business problem which serves as the basis for development of a simulation procedure. Considering that the original variables included into the problem as well as the results are arbitrary, it is necessary to know the law of distribution of the variables (uniform or normal) before simulation modeling. If the law of distribution of random variables included into the problem is unknown, it is necessary to conduct computational experiments both for the uniform and the normal distribution and compare them afterwards. Based on the comparison, preference is given to the option which yields the largest money receipts with the minimal net present value of the investment project. In the view of the foregoing, the templates (“Simulation”, “Analysis Results”) designed for simulation modeling for the uniform and normal laws of distribution of the key variables of the problem as well as the results (NCF, NPV) were developed in the work. Numerical characteristics were obtained for the key variables and the results, and their probabilistic analysis was carried out. In addition, a graphical comparative analysis of NCF, NPV was conducted for different distributions. A conclusion was made on the basis of the comparative analysis that if a large number of experiments are held, the best option is to select the normal law of distribution of key variables and results.

Substantiation of the Socio-Economic Efficiency of Personnel Management in the Modern Enterprise (p. 159 - 164)
The article is aimed at substantiation of specifics of the socio-economic efficiency of personnel management in the modern enterprise for purposes of career growth of employees. The algorithm of the socio-economic efficiency of personnel management based on the analysis and synthesis of scientific works and activities of the enterprises of the machine-building industry was developed and proposed considering two main components: economic and social. Managerial decisioning to ensure the social efficiency of personnel management is based on the evaluation of the level of the personnel career growth; setting priorities to improve the individual components of the personnel career growth in the enterprises' structure; questionnaire survey of employees to identify their propensity for the related career and the factors influencing the development of personnel. To address these challenges method of taxonomy and method of discriminant models building were used. Determination of the economic efficiency of personnel management in virtue of its career growth was proposed to be conducted on basis of an economic-mathematical model of cause-and-effect relationships between the improved indicators of the personnel career growth and the revenues of the enterprise. For this purpose, a correlation and regression analysis was carried out and a model was built, which allows to evaluate the economic efficiency of personnel management. The obtained results comprise the basis for the development of the complex of measures aimed at improving the system of personnel management in the enterprise. Article is written in Ukrainian

Readiness of Economic Entities to Abide by the Rules as Component of the Efficiency of Regulatory Policy (p. 164 - 168)
The article is aimed at one of the components of the efficiency of regulatory policy: readiness of the economic entities operating in the agricultural economic area to comply with the requirements of the regulatory acts. In the article the existing approaches to economic analysis of the readiness to abide by the rules, required by the regulatory policy, are studied and compared. This analysis allows to determine how the existing approaches explain the behavior of the entities of the agricultural economic area and also to create the theoretical background for the possible empirical analysis of the efficiency of regulatory actions by the State. In the article is concluded that the neoclassical theory in explaining the behavior of the economic actors focuses on the balance of profit – expenses. Given some limitations, this approach should include data variables in the model, which would explain the observance of requirements of the regulatory policy by the actors. However, there is also a need to address the social and psychological factors, personal motivations, social reciprocity and public pressure. Though the role of the neoclassical economic variables is well understandable, there are some difficulties with taking into account the uneconomical variables. However, it seems appropriate to add the following variables to the model: variable of the risk-free behavior in the case of potential profit and the riskful behavior in the case of potential losses; variables reflecting the influence of the psychological and social factors. A practical solution of building the model presupposes the availability of a few options, but the choice of the concrete solution of this particular issue must be the subject of a further independent research.

Retrospective Economic Evaluation of Mechanisms for Attracting Investments to the Enterprise (p. 108 - 113)
The study is aimed to define the methods of economic evaluation of mechanisms for attracting investments. This aim follows logically from the obvious need of an enterprise to have criteria for selection of the mechanisms for attracting investments and to form the order of their usage. Therefore the scientific papers on this problematics were analyzed and it was determined that solutions of the specified problem are still absent in the works of many scientists. Given this fact, the author has introduced his own methods for economic evaluation of mechanisms for attracting investments. Thus, in the article peculiarities of the functioning of these mechanisms are reviewed and the indicators that can be used for their economic evaluation are disclosed. On the basis of the results, derived from previous research, in this article the indicators of efficiency of mechanisms for attracting investments, as elaborated by the author, are presented and the method to calculate the one integral indicator is proposed. It is worth noting, that one of the most significant results of this research is that not all mechanisms to attract investments can be evaluated on the basis of retrospective data. It would be therefore advisable to a further research, aimed at definition of methods for the economic evaluation of the mechanisms on the basis of the expected future results of their usage.

Modeling of Managerial Reporting (p. 214 - 219)
The article is aimed to explore approaches to modeling of managerial reporting in the enterprise. It has been determined, that, in building models of managerial reporting, a modeling object is not a separate number of forms or indicators, but a system of forming the reports in its entirety, as a process. Analyzing the definition of «business process», it can be argued, that forming of managerial reporting should be considered as referring to the category of business processes, the end product of which is information about the company's activities. Information as the end product is turned into a managerial resource, providing the possibility of decisions-making, without which no existence of business is possible, thus making the process of forming the reports vital to the company. The study suggested that process of forming the reporting is considered as business process, that can be defined as a series of actions with clearly marked elements of informational input and output, and elaborating of reporting indicators as the end product. Developing a managerial reporting model is reasonable to start with an analysis of business processes, identifying of correlations and analysis of eventual changes. Modeling of managerial reporting can be accessed through the graphical notation tools as well as case-tools. Implementation of system of managerial reporting and improvement of its model are based on the same approach as the process improvement in organizations, namely: BPM or BPR.

Systemic Approach to the Planning of Major Repairs of Property Assets in the Water and Sewer Utilities Enterprises (p. 220 - 224)
The article is aimed to study the functional interrelationship of economic losses from accident management in the water and sewer utilities enterprises and the planned expenditures on major repairs, taking into account the frequency and intensity of hardware failures, as well as indicators of aging. The proposed economic-mathematical model allows to determine optimum frequency of major repairs, taking into account the factor of hardware failure rate, as well as amount of planned costs for major repairs. As result of the study the optimum amounts of planned costs for major repairs, taking into account the average rate of equipment aging, was calculated; insufficiency of funding for repairs has been identified and justified, that, with the proper funding for major repairs according to the proposed model, the enterprise has an opportunity to reduce annual accident management costs significantly. Prospects of further research in this area is to determine the sources of funding for major repairs, application of the contemporary methods of managerial decision-making – such as method of hierarchical analysis by T. Saaty – in order to build a hierarchical model for determining the optimal method of calculating the depreciation costs in the enterprises. Reforming of the existing system of major repairs in the water and sewer utilities enterprises in accordance with today's economic realities, taking into consideration the issues of the branch, accumulated through the years, is an objective need for the further sustainable development of enterprises.

Theoretical and Methodological Analysis of the Monetary Approach to the Exchange Rate Modeling (p. 116 - 123)
The article is aimed at theoretical and methodological analysis of the monetary approach to the exchange rate modeling. Absence of universal theory (model) of currency exchange rate formation, which would be effective in countries with different economic conditions, has been identified. Approaches that differentiate the classic models of the exchange rate are considered. Expedience of use of the monetary approach to modeling the influence of fundamental macroeconomic factors on the dynamics of the exchange rate has been substantiated. Transmission mechanisms within the framework of the monetary approach have been considered. It has been proven that a transmission mechanism from the monetary momentum, through prices and to the currency exchange rate is perfect and works instantly. The approach of so-called «sticky prices» in the framework of the exchange rate theory has been considered. Causes of occurrence of the time lags in the monetary transmission mechanism have been characterized. Dynamics of exchange rates in accordance with the monetary approach, which is determined by the relative supply and demand of money in the economy, has been considered in terms of long-term perspective. A contemporary vision as to the issue of demand for nominal money balances has been presented. Importance of using the logarithmic form of relationship between currency exchange rate and the factors that predetermine it has been substantiated. Article is written in Ukrainian

Determining the Level of Obsolescence in the Technological Audit of Intellectual Technologies (p. 137 - 142)
The article is aimed to develop methodical recommendations for estimating the level of obsolescence of intellectual-innovative technologies (intellectual property objects). A detailed analysis of the existing methodical framework has resulted in identification of the main shortcomings of the methodical base for determining the level of obsolescence of the intangible objects and developing a series of recommendations to address them. It has been proposed to take into consideration several scenarios of changes in the level of obsolescence, in particular, proportionate, active, passive and progressive use of intellectual technology. Separately allocated are the intellectual technologies that are poorly amenable to obsolescence. On the basis of actual situation as to specific intellectual technology, will be recommended, for practical calculations and in the valuation of intangible assets in particular, to use the factor of proportionality of obsolescence. A bivariant mechanism for determining this factor: the method of expert assessments and analytical method based on the criterion of quality by A.V. Glichev, which allows the use of a wide array of information on past, current and potential features of intellectual technologies, has been elaborated. Economic-mathematical models for practical implementation of the analytical approach to determining the proportionality factor of obsolescence are proposed. The developed models are recommended for practical use in carrying out technological audit procedures of intellectual property objects in industrial enterprises. Article is written in Ukrainian

On the Issue of Profitability Management of Enterprise's Equity Capital on the Basis of Target Indicators (p. 149 - 154)
The article is aimed to study and substantiate the approach to the profitability management of enterprise's equity capital. The concept of «profitability management of equity capital» has been improved, which makes it possible to determine the components and goal of management. The mechanism for determining the target profitability of equity capital as ratio of target amount of net profit to the target value of enterprise's equity capital was considered. In the present context, more attention should be paid namely to the target level of profitability, rather than the maximum level. Target level of profitability depends on the amount of net profit that is necessary for enterprise's development and formation of reserves as well as amount of equity capital in terms of the acceptable financial risk. It has been proposed to manage the profitability of equity capital through the factor indicators that form this profitability, their possible change in the planned year and target values should be taken into consideration.

Dynamics of Gross Regional Product: Analysis Based on the Methodology of the Neoclassical Growth Theory (p. 97 - 102)
The article is aimed at studying the dynamics of gross regional product (GRP) per capita in Ukraine on the basis of the methodology of the neoclassical growth theory. The task of this study was to build a model to analyze the presence of convergent or divergent trends in the level of GRP per capita. As result of the study the most common methodological approaches of the neoclassical theory to the analysis of convergence have been summarized, an own method of calculating the factorial signs used in terms of the neoclassical analysis has been proposed. Adequacy of the analytical model, as well as weight and significance of the correlation relationship and regression parameters has been estimated. Analysis of values of the model parameters allows to conclusion that there is no stable trend of convergence or divergence in the level of GRP per capita over the analyzed period. However, it can be argued about the presence of a weak trend of divergence in the dynamics of GRP per capita. Further research should focus on the use of methodology of the neoclassical growth theory for analysing the dynamics of other indicators of regional development, as well as on the improvement of research methods by adding structural parameters of regional development to the model.

Modeling of Development Trends in the Non-Bank Financial Institutions in Ukraine (p. 103 - 107)
The article is aimed to estimate the current status of activities of non-banking financial institutions in order to build an econometric model to create favorable conditions for regulating the market of non-bank financial services and formation of managerial decisions aimed at improving the effectiveness of its activities. It has been determined that factors acting on the market of non-banking financial services, have both a positive and a negative influence on the activities of its members, so there is a need to manage these factors. In order to build an adequate econometric model has been proposed in each component of the market of non-bank financial services to choose the major participants that form the supply and demand in these segments. Statistical observations on the number and size of assets of insurance companies, credit unions and joint investment institutions formed the basis of the econometric model. The proposed econometric model of development of non-banking financial institutions in Ukraine, on the basis of the actual state of the market of non-bank financial services, gives an opportunity to predict the regulatory influence of the State on the participants in this market in order to increase their effectiveness and their functional positive impact on the resulting indicator – GDP.

Two-Factor Model of a Rational Profit-Oriented Behavior of Household (p. 108 - 112)
In the article relevance of research of the economic, in particular the profit-oriented, behavior of household, which is a form of a small social group, is substantiated. A model of rational profit-oriented behavior of household in the form of a system of ordinary differential equations is built, in which the factors of change of the amount of total income are the available income and dimensionless value of human capital. It has been determined, that in the medium term the motivation for increase of human capital turns out to be effective, which is aimed at increasing revenues, but in the long term – the one aimed at achieve a certain level of the human capital value, which in turn provides the positive dynamics of total income. One of the directions of further research is to expand the existing models by dividing the indicators of forming the household income on the endogenous (profit and mixed income; income from property) and the exogenous (wages; social assistance and other current transfers).

Simulation of Advertising Costs on Electronic Trade Market (p. 113 - 118)
In the article, a simulation of advertising costs in electronic commerce is carried out. A modification of the classical Salop model to correct for the influence of Internet sellers on consumer preferences by means of non-informational advertising has been implemented. In the modified model, advertising costs are implicit function parameter in consumer utility, which shifts the demand curve immediately, increases the consumer utility and the willingness of consumers to make purchases. Relationships of amounts of advertising expenses, number of sellers and volumes of electronic trading market have been explored. It has been displayed that with expansion of trade market advertising costs of on-line sellers are exponentially increasing. The increase in the number of on-line sellers helps to reduce the advertising costs, and consequently, consumer utility of items for each customer is reduced, which in turn lowers the maximum price level, which can be set by a seller. With a permanent number of consumers in the market, growth of advertising costs when reaching the limit of saturation does not increase the target audience and the level of readiness to purchase advertised products. Expansion of electronic trade market after reaching certain values leads to a decrease in the number of on-line sellers in the market, in this case, increasing advertising costs begin to exceed the sellers profit from the market expansion.

Model of the International Migration Influence on the Economy of Ukraine (p. 119 - 124)
In the article has been determined that, although various aspects of available theoretical concepts of migration are still in use, the unified general theory of migration still does not exist. This is why classical theories of migration do not lose its relevance to this day and can be useful for solving problems and achieving assigned goals. During the years of independence, Ukraine formally established State institutions, whose duties include the management of international migration, as well as laid foundations of the regulatory framework in this sphere. Though, even at the present stage, the State lacks a clear, scientifically sound and, most importantly, realistic foreign policy of migration, which would take into account the current demographic situation and the status of the domestic labor market and meet interests of the State in a whole, its individual regions in particular, as well as various groups of the population, including direct migrants. On the basis of assessment of an econometric model of the migration influence has been displayed that the total income from working immigrants in Ukraine are lower than the relative rates of changes as to selected factors. If the employment income will increase by 1%, the relative growth rate of the labor force in Ukraine will increase by about 4% when all other factors remain unchanged. With this in mind, the strategy of Ukraine's participation in the global migration processes should be focused on reduction of poverty. Article is written in Ukrainian

System for Monitoring Risks in Operation of the Corporate Electronic Document Management System (p. 83 - 88)
The article is aimed at development of the basic principles of risk monitoring for a system of the effective corporate electronic document management. Monitoring of phenomena, processes and their characteristics is necessary for supporting the science-based decision-making in the operation of an electronic document management system. The concept of «monitoring» is interesting in terms of its theoretical analysis because it does not have an exact unambiguous definition, being used in the various areas of scientific research and practice. The complexity of wording of the definition of the «monitoring» concept is also associated with both the science and practical application: monitoring is used as a way to study the object, and as a way to ensure the scope of management activities by means of providing timely and quality information. The article suggested the definition of monitoring risks in electronic documentation management system as the constant supervision of factors that may give rise to risks during the movement of document in electronic documentation management system as well as accumulation of relevant information on the nature of risk origin. The main principles and functions have been allocated, both the formal and the mathematical model of the indicated monitoring system have been built. Article is written in Ukrainian

Risk of Lowering the Level of Food Security in the Regions of Ukraine under Conditions of Economic Downturn (p. 92 - 98)
The article is aimed at evaluating on the basis of empirical data the risk of lowering the level of food security in the regions of Ukraine and determine its factors by using the econometric simulating techniques. Analysis of scientific papers by domestic and foreign scientists helped to choose binary regression as a toolkit that can be used to evaluate risk as a probability of occurrence of undesirable event, in our case – lowering the level of food security in the regions of Ukraine. On the basis of statistical data on regions of Ukraine during the period from 2000 to 2013, logit and probit regressions with consideration of panel data structure were built. As result of the research has been found that the significant factor, which leads to reduce of the possible deterioration of food security in regions, is the growth of real wages. Besides, reduction of the risk is affected by increased gain in production of cereal crops and vegetables, though not as much as the growth in wages. At the same time, growth in potato production increases the risk of deteriorating food security in the regions. Article is written in Russian

Multiagent Model of Economic Evolution: Analysis of Sensitivity of Trajectory (p. 105 - 112)
On the basis of the postulates of evolutionary economics, hypotheses of model of economic agents interaction have been formulated, which are formalized by the following set of assumptions: release of agents is described with the Cobb-Douglas production functions; only the economic agents with sufficient investment means may become innovators; agents interact, buy and sell technologies; agents that do not have sufficient amount of capital, pass away; successful economic agents can «spawn a child» and allocate it to the technology and production factors. Based on the listed assumptions, a multiagent model of economic evolution has been developed in the NetLogo software environment. A series of experiments with the model were carried out to analyze the sensitivity of trajectories of total release of agents to the changes in exogenous variables: the initial number of agents, prices of technology, upper limit of capital, with reaching of which agent will be capable of becoming an innovator or «spawn a child», and lower limit of capital, with reaching of which agent passes away. Conclusions about the generated model modes of economic evolution have been drawn. Type of functional dependency between the average value of the absolute growth of aggregate release and values of exogenous parameters of the model has been determined. Practical significance of the constructed evolutionary model of interaction of economic agents is represented by the possibility to analyze the impact of technological development on the nature and pace of macroeconomic dynamics.

Modeling of Strategic Development of Creative Component of Management of International Companies in the Software and Computer Services Sector (p. 78 - 87)
The article is aimed at exploring the innovative-creative component of management of companies in the software and computer services sector (henceforth – IT-companies), based on its qualitative and quantitative analysis, and studying the correlation relationship between this indicator, research and development costs, as well as company's profit. In results of the study, structural elements of innovative-creative component of management of IT-companies have been identified, its qualitative analysis in the measuring coordinates of «criteria – indicators – showings» has been carried out, and a quantitative analysis has been presented that outlines the author's approach to the development of integral index for development of innovative-creative component of data management of company based on their clustered organization. The conducted comprehensive analysis allows to develop an index of creativity in terms of management system, which in the nonlinear model determines the impact of the optimum amount of research and development costs on the company's profit. The index of creativity characterizes the innovative-creative component of management of IT-companies and represents an integral indicator of its development. It has been proved that the rate of increase in the profit of IT-companies is inversely proportional to the potential profit with the proportionality coefficient – the creativity index of management system. The subject of further research can be conceptualization and improvement of the methodology for the calculation of the integral indicator of the innovative-creative component of management as for IT-companies, so for the companies operating in other economy sectors.

The Economic-Mathematical Model of Dependence of the Intensity of Investments Inflow from Depreciation Policy in the Realities of the Ukrainian Economy (p. 93 - 99)
In the article has been studied that taxation-depreciation policy is one of the main tools to ensure stimulation of investment development of the Ukrainian economy. It has been determined that an important tool for taxation-depreciation policy is accelerated depreciation, which belongs to the tax benefits and effectively use to stimulate investment in countries around the world, including in the high-tech economies, since moral depreciation of fixed assets in the budget-making industries of these countries significantly exceeds the physical, and attraction of investments allows to actively update such funds. Based on the Nauss-Shapiro model, has been developed and implemented an economic-mathematical model of dependence of the investments inflow into the economy by applying depreciation regulations to the realities of the Ukrainian economy. On the results of implementation of the model, the depreciation coefficients have been determined, which ceteris paribus maximize the amount of investment in the economy as a whole as well as in the individual sectors of the economy.

Optimal Pricing of the Credit and Deposit Products of Commercial Bank (p. 100 - 108)
The article considers the process of determining the optimal credit and deposit rates of commercial bank that maximizes the capital of bank at the end of the period of management. To accomplish this task, a bank model was used, in which the deposits and credits are presented as cash flows, depending on the credit and deposit rates respectively. A brief description of the model together with a list of assumptions on which it is based was provided. On the basis of the above model, the task of maximizing the capital upon condition of control over the credit and deposit rates was given. To accomplish this task, numerical simulation was carried out using the method of coordinate-wise convergence. It has been found that the optimal credit and deposit rates depend on the bank's capital at the beginning of the period of management as well as on the function parameters in terms of demand for credits and supply for deposits. The higher is the bank's capital management at the beginning of the period of management, the smaller are the optimal credit and deposit rates, however, starting with some level of the capital and above, the optimal rates stay not reduced. The optimal rates will be also decreasing over time as capital increase grows up to a specified level. Consequently, the amount of attracted deposits decreases and the volume of issued credits increases up to a certain level. Article is written in Ukrainian

Methods of Economic-Mathematical Modeling in the Costs Planning of Industrial Enterprise (p. 67 - 72)
In the current economic crisis conditions, in which operate the most of industrial enterprises of Ukraine, the search for directions of optimization of their activities is one of the priorities of their further and strategic development. Today's situation is such that top management of the industrial enterprises does not pay due attention to reducing costs of enterprises, so the publication proposes to use methods of economic-mathematical modeling in the costs planning. One such method is the linear approximation, which gives the possibility, on the basis of the actual data on business activities, namely the dynamics of costs of the principal activity and dynamics of volumes of the marketed products, to build models of dependencies of «costs of the principal activity – volumes of sales». An analysis of the built models displays once again the circle of problems of machine-building enterprises, on solving which their further development and the efficiency of their activities depend. A special place in this process takes planning, because it gives the possibility, on the basis of the analyzed factual data on activities of industrial enterprises, to plan not only costs of the principal activity, but also further development of these enterprises.

A quantification to assess the narrowness of relationship between the random variables in MS Excel is proposed to be carried out in two ways: using the statistics functions COVAR () and CORREL () and using special tools for analyzing statistical data: Data analysis ? Correlation. If the number of the studied variables is higher than 2, a more convenient choice will be to use the Excel analysis tools. Usefulness of the statistical analysis of source data and the results of the simulation experiment is that in many cases it helps to reveal inexactness in the source data, or even errors in the task statement. Statistical analysis also allows to test the hypothesis about the normal distribution of both source data and results. To do this, special statistical criteria by Kolmogorov-Smirnov, Pearson and others can be used. MS Excel provides to quickly and effectively implement a calculation of the required criterion and conduct a statistical assessment of hypotheses by means of the descriptive statistics tool that automatically calculates the characteristics of distributions, which are widely used in practice.

Analysis of the Impact of the Resource Orientation of the Export and Import Economy Components on the Level of Interregional Differentiation in the Socio-Economic Development of Ukraine (p. 90 - 101)
The article is aimed at studying the influence of the resource orientation of the export and import economy components on the level of interregional differentiation in the socio-economic development of Ukraine. The methodological basis of the study is the Sachs-Warner model, whose key position indicates a negative relationship between the proportion of valuable minerals in the structure of national exports and the economic growth in the country (the so called phenomenon of «resource curse»). Modified within the present study, the Sachs-Warner model provides an analysis of impact of the share of mineral resources within the structure of the national exports and imports on the level of interregional differentiation in terms of GRP, GRP per capita, available income, wages, money incomes and expenditures of households. In addition, the methodology of the study involves an analysis of the interregional measuring of impact of the proportion of exported and imported minerals on the specified indicators of the socio-economic development of the regions of Ukraine. The results of the study indicate that the proportion of minerals in the structure of the national export reduces the interregional differentiation at the level of available income and deepens it at the level of both wages and capital expenditures, the share of imported minerals reduces the differentiation at the level of GRP and GRP per capita. Synthesis of the results of the analysis of the interregional phenomenon of «resource curse» suggests a different nature of the relationship between the resource component of the regional exports and imports and the socio-economic development of the regions of Ukraine.

Methods for Substantiating Indicators in the System for Controlling the Balance of Socio-Economic Development of Regions (p. 106 - 111)
One of the dominant trends of the territorial development is seen as strengthening of imbalances, increase in the interregional differentiation, uneven distribution of capacity growth. The existing situation displays weakness of the mechanisms of the system for regulating the regional development, distortions towards the market mechanisms of regional development, necessity to improve the regional policies, mechanisms for ensuring the balanced development of regions, aimed at improving efficiency in the use of scarce resources, accelerating the return of the system to the trajectory of equilibrium growth. Among the main functional tasks for such mechanisms, the task of substantiation of a system of indicators for the socio-economic development of regions has been allocated. So far the issues of evaluating the informativeness of indicators, studying the sustainability of the system of diagnostic signs in the dynamics have remained underexplored. The publication proposes an algorithm, which is based on synthesis of the methods of principal components as well as canonical correlations, allowing to conduct analysis of the spatio-temporal variations of signs, structure of their relations, which increases the validity of the choice of indicators for monitoring in the system for controlling the balance of socio-economic development of regions.

Resource-Oriented Exports and Imports as a Factor of the Socio-Economic Development of the Regions of Ukraine (p. 112 - 122)
The article is aimed at studying the influence of resource-oriented exports and imports on the level of socio-economic development of the regions of Ukraine. The methodological basis of the research is a modified model of Sachs and Warner, which is based on the analysis of a correlative-regression relation between the share of exported and imported minerals and the indicators of socio-economic development of regions for the period of 2006-2013. The results of the study indicate that an increase in the share of the minerals in the structure of exports negatively affects the socio-economic development of the indicators for Zakarpattya, Zaporozhzhya, Kyiv, Lviv, Mykolayiv, Poltava, Ternopil, Cherkasy, Chernivtsi and Chernihiv regions. This correlation relationship was positive for the economy of the Republic of Crimea, both Vinnitsa and Sumy regions. The share of imported minerals had a positive impact on the socio-economic development of Vinnytsia, Zakarpattya, Zaporozhzhya, Kyiv, Lviv, Kharkiv, Cherkasy and Chernigiv regions. Statistical characteristics of the modified model of Sachs and Warner indicate significance and practical importance of the analyzed correlative-regression relationship in the regions of Ukraine for the indicators of the capitation GDP and the available income when analyzing the period in question.

Conceptual Model of Economic Behavior of Households in Conditions of Self-Sustainment (p. 137 - 141)
The article examines the issue of modeling the economic behavior. An assumption about an analogy between the «creation-consumption» processes in economy and the «evulsion-absorption» in hydrodynamics is introduced. The kinetic structure of such elementary material flows has been determined. It has been found that consumption (spread) of resources for an isolated point of consumption (production) has the same spatial structure and speed characteristics as fluid movement in the area of runoff (source). It has been suggested to name a production point «economic source» and the point of consumption – «economic runoff». As a model of economic behavior of household in conditions of self-sustainment, a combination of economic source and economic runoff, which forms an economic dipole, has been suggested. Further development of the proposed methodology would allow to study the possible (necessary) behavioral reaction of an economic agent to the impact by both endogenous and exogenous factors.

Using Adaptive Forecasting Models in the Contemporary Conditions of the Financial-Economic Space (p. 149 - 155)
The article is aimed at a theoretical-methodological substantiation and practical application of the adaptive forecasting models in the development of adaptation measures. Evolution of the use of adaptive models, particularly its simple form – exponential smoothing – as well as change of its basic principles when building forecasts has been considered. It has been determined that most adaptation measures are directed to «survival». However, current conditions put forward other requirements: in order to become competitive, «protective» methods are not sufficient, there is the need for adaptation measures aimed at development. With regard to the volatile and uncertain financial-economic space, the best basis for establishing such measures is the short-term forecasting (until 3 years) that would preserve the representativeness of the results. Thus, the methodology set out in article as to applying adaptive models for enterprises is also suitable for forecasting of main parameters of banks' activities with introduction of corresponding adjustments and refinements that will improve efficiency of the process of adaptation to characteristics of the financial-economic space.

Increased Regional Imbalances as the Dominant Trend of Territorial Development: Assessment and Effects Analysis (p. 156 - 164)
The article displays that the dominant trends of territorial development in the context of globalization and transnationalization of markets are increased irregularity of regional development, rapid polarization of the economic development of individual countries and regions, spatially stable economic concentration. Effects of the increased irregularity of regional development are higher vulnerability of economy, its reduced stress resistance towards external «shocks». A conducted analysis showed that the potential for economic growth is concentrated mostly in the economically developed regions, where trade and financial flows are effectively built into the system of global competition. For most macro-regions and interior regions channels for technology transfer and deployment are unavailable. This leads to reproduction of the trend of increased irregularity of regional development, both at the level of world dynamics and at the level of individual regions. Examination of the level of irregularity of the regional development of Ukraine, assessment of its effect on economic growth based on production-institutional functions suggest that indicators of the regional development irregularity substantially exceed the threshold (safe) values, i.e. the imbalance of economic space is becoming a threat to the stable development of the economic system that requires improving the existing mechanisms for the State regulation of regional development.

Fractal Analysis of Foreign Exchange Market by Means of Monitoring the Hurst Exponent (p. 125 - 131)
The article analyzes the behavior of currency quotations at the foreign exchange market by identifying dynamic changes in time, in terms of the Hurst exponent, as a tool of fractal analysis, belonging to the fractal market hypothesis. Calculations of Hurst exponent by the adjusted formulas of the R/S analysis for 17 major currency pairs at the closing prices as well as the prices of maximum/minimum have been carried out. A comparison of the results within the timespan of 2008-2014 has been conducted, providing for comparing the exponent value at the foreign exchange markets of different countries under different economic conditions. The Hurst exponent of currency pairs in terms of the stable economic situation tends to preserve its average value, further on, it indicates the events that directly or indirectly affect the State's economy and its national currency exchange rate. Application of the method of «sliding window» has allowed to simulate the dynamics of the Hurst exponent for the following currency pairs: USD/JPY, GBP/JPY, EUR/USD, GBP/USD and to set certain patterns of conduct for the quotes series resulting from the appropriate response to the economic, political and natural disturbances.

Developing Scenarios of Reputational Risk Management for Intermediary Enterprise (p. 144 - 148)
Despite a large number of practical recommendations how to reduce reputational risk, available in the publications, the issue of possibility, nature and efficiency of control actions, as well as the impact of their practical implementation remains open. To substantiate decisions on the management of reputational risk for intermediary enterprise, it is necessary to develop related scenarios, this consideration has become the purpose of the article. Possibility of applying cognitive methodology for the elaboration of reputational risk management scenarios has been substantiated and sequence of scenario development has been determined. When developing scenarios of reputational risk management, direction board of an intermediary enterprise should take account of the current status of the reputation risk components, value of the unmanaged factors (goodwill, brand awareness) as achievements of the enterprise, existing resource constraints, as well as management targets (profit, financial sustainability). As result of cognitive modeling, some scenarios of reputational risk management have been developed for their further implementation in the management practice of an operating intermediary enterprise.

Modeling the Processes of Supporting Decision-Making in the Innovative Clusters (p. 172 - 177)
The article is aimed at studying the modeling the processes of supporting decision-making in the innovative clusters. In order to study the processes of supporting decision-making in the innovative clusters along with conducting model experiments it is advisable to use game-theoretic models, because corporate infrastructure of innovation cluster is characterized by availability of a distributed control, while participants would implement their activities in situations of conflict and uncertainty. It has been revealed that some mathematical models solve similar challenges. Modeling the processes of supporting decision-making in the innovative clusters should occur at four levels: public; regional; level of innovation cluster (facilitator); level of participant in the cluster. For modeling the processes of supporting decision-making in the innovative clusters, evident advantages of agent-oriented approach are: reduction of time for solving problems, reducing the amount of transmitted data by means of transfer of the higher-level partial solutions to the other agents; shortening the time for agreeing terms and conditions as to development, sale and introduction of innovative products.

A General Model of Pricing of Loan and Deposit Products by Commercial Bank Subject to Stochastic Lag In Returning Loans (p. 47 - 51)
The article considers the issue of accounting for the possible delays in returning loans within the process of pricing the loan and deposit products of commercial bank. According to the complexity of this task, the literature commonly uses the more general indicator – credit risk, which does not give sufficient detail to account for the influence of lag when returning loans. Thus a general model has been built, which takes account of stochastic lag in returning loans and deposits. To this end, a number of model assumptions has been formulated, the mechanisms of return of loans and deposits have been disclosed and the choice of formula writing for them has been substantiated. Using such incoming and outgoing flows, based on the flow model, a general model for commercial bank has been proposed that provides to: consider the stochastic lag when returning loans and deposits; choose different demand functions for loans and deposit offerings; conduct simulations with a fixed delay (as a special case) and with a random delay; use different pricing criteria; find the best credit and deposit rates subject to lag in returning loans by means of numerical simulation.

A Systematic Approach to the Evaluation of Options Based on the CEV-Model (p. 155 - 159)
The article is concerned with studying the derivative assets, using tools for spectral analysis, as well as of the singular and regular perturbation theory. Using the risk-neutral valuation, we obtain the Cauchy task, allowing to calculate an approximate price of derivative assets and their volatility based on a diffusion equation. In the overall diffusion we add two quickly and slowly changing factors of the nonlocal volatility to obtain a model with the multivariate stochastic volatility. Combining the methods of spectral theory of singular and regular perturbations, one can calculate the price of derivative assets as degradation by native functions and the own values of linear operators and solution of the Poisson equation. Prospects for further research in this direction will be improvement of spectral theory and dissemination of the results of the publication on the cases when the equation, from which the eigenvalues are found, has no discrete spectrum, as well as when the stochastic volatility depends on four or more disparate factors that are present in the stock markets.

The Mathematical Model of the Economic Conduct of a Household in the Conditions of the Steady Action of the Exogenous Factors (p. 111 - 115)
The publication has the primary aim of building an economical-mathematical model of conduct of an economic entity, prone to self-organization, in the process of interaction with the established external factors. The proposed model is considered in the space of conditions in the form of a linear combination of functions of movement of the economic dipole and a uniform material flow. On examining the model, dependence of size of the «stability field» that determines the amount of resources required for ensuring the viability of the economic entity from the parameters of both the internal and the external flows has been determined. It has been determined that the economic entity is motivated to resist the external factors rather than to mantain the equilibrium. Article is written in Ukrainian

The Convergence of Profitable Groups of Households by the Consumption of Food Products as a Condition for Strengthening the Food Security (p. 116 - 123)
The article analyzes the economic affordability of foods for various profitable segments of the population, and studies the dynamics of differentiation of consumption of the basic food products in the households with different monetary income. In order to analyze the economic affordability of foods to the households of different profitable groups as one of the key indicators of food security, coefficients of elasticity of volumes of food consumption have been calculated by the revenues and costs. For studying the dynamics of differentiation of the food consumption in households with different cash income, indicators of both the ?- and the ?-convergence have been calculated. According to the results of the calculations has been found that for the period from 2000 to 2015, for all groups of the basic food items, the phenomenon of convergence can be observed, i.e. reducing the differentiation of their consumption volumes over time in the households with different monetary income, which has a positive impact on enhancing the food security in the country.

Using the Survival Tables Method in Studying the Status of Sanatorium in Ukraine (p. 128 - 133)
The article is aimed at studying the efficiency of the recreational activities of sanatoriums of Ukraine on example of the sanatorium «Chervona Kalyna» (village Zhobrin of the Rivne region), using the survival tables method. As result of the carried out analysis of impact of the recreational activities of the indicated institution has become evident that the core functions of the sanatorium include: resumption, strengthening, and maintaining the health of patients. In addition, as a result of the carried out empirical research, we have found that in patients of the indicated sanatorium the treatment efficiency declares itself most often on the 11st day after the start of treatment. And the first signs of healing can be seen already on the 5th day of stay in the sanatorium. Also a natural regularity is the fact that the longer a patient is being treated in the sanatorium, the more efficient the treatment is, which is expressed in the improved status of health. However, we came to the conclusion that, in order to provide efficiency of the recreational activity of the sanatorium, patient must be treated in it for at least 14 days.

The Mathematical Model of the Economic Behaviour of Household in Terms of the Increasing Impact of Negative Exogenous Factors (p. 83 - 87)
The main aim of the publication is to build the economical-mathematical models of behavior strategies of economic agent, prone to self-organization, in the process of interaction with the negative external factors when they become strengthened. The proposed strategies and their models are based on the cost-income balance equation that takes into consideration both the quantitative and qualitative characteristics. The built models are considered in the state space, in the form of linear combinations of functions of movement of the uniform material flow and different spatial combinations of the economic sources (sink points). Study on the model has provided to define dependence of the size and shape of the «area of stability» that determines the amount of resources required for viability of the economic agent, both from internal and external flow parameters and the chosen strategy. It has been found that as the criterion of efficiency of the applied strategy can serve the value of the «coefficient of resistance» against the external factors, reduction of which, along with keeping the size of «area of stability», corresponds to the direction to optimization.

Evaluating the Impact of Competition on the Work of Editorial Bodies of the Local Communal Print Media (p. 55 - 61)
The article evaluates the impact of competition on the work of editorial bodies of the local communal print media. The indicators of profitability of communal newspapers, their circulation, and the cost of subscribing in terms of regions were researched. An indicative framework has been defined and, proceedng from results of the correlation-regression analysis, impact of the demographic, institutional, economic, social, infrastructural factors and indicators of performance of communal newspapers on the number of profitable communal publications, the amount of local budget subsidies, and the average annual cost of subscriptions have been evaluated. The identified features of relationship between the factors allowed to allocate only one significant factor of influence on the number of profitable communal newspapers and none for the local budget subsidies and the average annual cost of the subscription. The carried out calculations led to the conclusion that profitability of the editorial bodies of the local communal print media is provided, above all, by efficiency of their management. The external factors, although they form a competitive environment for the local media, have no significant impact on their profitability. Article is written in Ukrainian

The Model of Optimum Economic Growth with the Induced Scientific-Technological Progress (p. 101 - 105)
On the basis of the economic dynamics of the Harrod – Domar model, a model of optimum economic growth in line with the induced scientific-technological progress (STP) has been built. In order to reflect the induced scientific-technological progress, with this model is proposed to further allocate the income element that is specially used for the investment of innovation activity, implementation of which reduces the capital intensity in development of the discussed economy. For the simplest way of presenting an economic mechanism for the investment of induced STP, analytical solutions of an appropriate task in optimum management have been obtained. Studying these decisions allowed to reveal the characteristics of the impact of parameters of scientific-technological progress and the analyzed economic system on choosing the best trajectory for its evolution. Possible directions for further developing the results presented can be considered the tasks in building and analyzing models of optimum economic growth that implement different investment options for the induced STP, as well as the models in which this investment mechanism is not exogenouslyed, but rather the result of the corresponding economic-mathematical research.

Modeling the Impact of Mergers and Acquisitions of Companies on their Capitalization (p. 106 - 112)
In the context of economic globalization, the most common approaches to creating powerful companies that have high market value are those that use mergers and acquisitions. In Ukraine, such processes also have been considerably intensified in recent years. However, in the national economic science, the problems of evaluating the impact of mergers and acquisitions of companies on their capitalization, as well as on the concentration and competitiveness of the country’s economy, have not been solved to date. The article is aimed at analyzing the market capitalization of the world’s largest companies and modeling the impact of their mergers and acquisitions on the capitalization of their economies. As a result of the study, it has been determined that modeling the impact of the mergers and acquisitions of the world’s companies on the level of capitalization of their economies has proved the hypothesis that the countries of the world, where mergers and acquisitions of companies are more extensive, also have larger capitalization level.

The Intersectoral Balance in the System of Development of Integration Relations as a Factor for Economic Growth of the Agrarian Economy Sector (p. 113 - 119)
The article is aimed at developing a model of economic growth of the agrarian sector of the Ukrainian economy through the development of intersectoral integration relations. It is displayed that the loss and severance of the linkages that existed in agro-industrial production prior to the reform of agrarian sector have become one of the causes of the crisis developments in this sector, and therefore a necessary prerequisite for integration is re-establishment of the system of linkages between disparate elements of integrity. By taking as basic the «costs – output» table, the main methodical approaches to assessing the level of integration were critically analyzed, a system of indicators was substantiated, and their economic content was further refined. The hypothesis about the functional link between the level of development of integration relations and the economic growth in agrarian economy sector has been proved. By taking as target criterium the maximum total value added, a dynamic model of the non-linear economic growth of the agrarian economy sector was built on the basis of the intensive development of the intersectoral integration relations.

Evaluating the Financial Flows of Bessel Processes by Using Spectral Analysis (p. 120 - 124)
The article solves the two-parameter task of evaluating the intensity of diffuse Bessel processes by the methods of spectral theory. In particular, barriers for cost of options, where the derivative of financial flows turns into zero, have been considered, and a task for the two-barrier option has been solved, which corresponds to Bessel process. A Green’s function has been built for the diffusion Bessel process of the two-barrier option, decomposed according to the first-type system of Bessel functions. The barriers are taken in such a way that the derivative of financial flow in terms of price is turned to zero, i.e. there are the points where flow can acquire extreme values. On the basis of Green’s function, the value of securities has been calculated. It is handier to use similar barriers when monitoring a stock market. The Green’s function for this task, which represents the probability of spreading the option price, is represented through the Fourier series. This provides an opportunity to evaluate the intensity of financial flows in stock markets. Article is written in English

Assessing the Impact of Renewable Energy on the Socio-Economic Indicators (p. 134 - 140)
Renewable energy sources increase their share in the energy sector because of a number of significant threats resulting from emissions, discharges and wastes from energy production through environmentally-dangerous and economically unacceptable technologies. The article examines the dependency between energy consumption per capita, GDP, and human longevity. The dependencies, which include economic, social, and environmental factors, are represented by polynomials that express the influence of each of the factors, as well as their mutual influence. The degree of polynomial depends on the number of factors influencing the processes that are described by the dependency. In the countries with developed economies and, consequently, health-care systems, there is a bigger correlation between renewable energy production, GDP, and longevity, than in developing countries.

The Regularities of the Cyclical Development of the World Economy in the Current Phase (p. 106 - 111)
The article is aimed at identifying and describing the key tendencies in the cyclical development of the world economy. In order to allocate the cyclical component in the dynamics of the world-wide GDP growth, a time series decomposition was performed using the Hodrick-Prescott filter and the relationship of economic cycles to the dynamics of different indicators of economic conditions was analyzed. The persistent relationship between inflation, unemployment and the current phase of the economic cycle have been identified and described. The truth of the Phillips curve has been empirically demonstrated: existence of an inverse relationship between the rate of inflation and the level of unemployment. A new classification of branches of economy has been provided according to their susceptibility to the current phase of the economic cycle. According to this criterion, all branches of economy have been divided into the cyclical and the non-cyclical sectors. A hypothesis that there is a direct relationship between the average annual growth rate of GDP and the structure of the national economy has been suggested. Article is written in Russian

Institutions as a Constituent of the Social Wealth and a Factor of the Synthesis of its Constituents (p. 128 - 135)
The publication is aimed at studying the role of institutions in the development of modern macroeconomic systems and the growth of their wealth. The integral, integrated, logical approach plus the mathematical modelling method were used for carrying out the analysis. It has been found that the value of institutions is defined for society through cost reduction, as opposed to the value of other accrued benefits that exist in forms of valuable material things, knowledge, information, etc., and the worth of which, accordingly, is determined by the growth of the end result (increase in their volume). A classification of institutions by the criterion of their efficiency for the development of society has been proposed. The economic-mathematical model has been built and analyzed in the form of a regression equation that expresses the dependence of GDP according to the purchasing power parity (PPP) per person from the corruption perception index. It has been found that there is a stochastic link between the corruptness of public governance and the formation of the wealth of modern macroeconomic systems. The obtained results can be applied in the sphere of public governance in the formation of Ukraine’s social and economic policy. Prospects for further research are an in-depth examination of the relationship between the institutional infrastructure of society and the level of its wealth. Article is written in Ukrainian

The Cognitive Modeling of Development of Tourism Sphere (p. 166 - 173)
The article explores the inter-sectoral interaction in the tourism sphere, which is based on the application of cognitive modeling. The authors consider the interaction of powers (political environment), tourism (tourism business), business (socio-economic environment) and ecology (ecological environment). The ecology is identified as the exceptional decisive factor in creating an enabling environment for the development of the market for tourism services. A static analysis of the cognitive model was carried out, which revealed 624 contours, of which 473 were stabilizing and 151 were destabilizing. Based on results of the systemic characterizations of the cognitive model, it was found that the interaction between the two sectors, tourism (tourist business) and business (socio-economic environment) needs special attention. A dynamic analysis of the built cognitive model was carried out using the method of impulse processes that helped to generate alternative scenarios for the development of tourism services. As a result, it has been found that increased investment in restaurant and hotel activities facilitates the increase in the level of development of market for tourism services for one period earlier than the increase in financing tourism sphere from the budget.

The Diagnostics of the Bank Financial Status: Credit Risk Management (p. 173 - 177)
This article analyzes the methodology for determining the credit risk of active operations of bank, as laid down in the Regulation on determining by banks of Ukraine the credit risk size on active banking transactions; a simplified algorithm for using it in practice has been provided. A study of the methodology, proposed by the National Bank of Ukraine, has revealed outstanding issues, such as adjusting the probability factor of borrower’s default, taking into consideration the retrospective. In view of this situation, it has been suggested that any generally acceptable methodology should be used. It is emphasized that the quality of the bank’s credit risk management can be determined by evaluating its credit portfolios for compliance with the regulatory acts and by comparing the difference between the bank’s actual risk and the actual amount of reserve funds, established by the bank. At present, the process of determining credit risk is excessively complex and cannot be fully automatized, and therefore needs to be substantially further elaborated. Article is written in Ukrainian

Substantiating the Target Level of Economic Security of Transport Enterprises and the Instrumentarium for Its Provision (p. 183 - 190)
The article is aimed at substantiating the methodology for assessing the economic security of transport enterprises, determining the target level and the instrumentarium for its provision. The proposed methodical approach to the assessment of the level of economic security of transport enterprises includes the determination of the level of counteracting threats and is based on the principles of integral estimation. The formed integrated indicator includes both indicators of counteracting the internal (human, managerial and technological, force majeure, financial) and external threats (market, stakeholder, power-based, natural, infrastructural). Each measure of counteracting threats is determined by results of assessment of dynamics of the three indicators. A practical testing of the proposed approach is carried out in the case of transport enterprises. Based on the established equation of the regression relationship between the level of economic security and the financial strength, a target level of economic security of transport enterprises has been substantiated. The instrumentarium to provide a targeted level of economic security according to the threat types, including preventive and reactive measures, has been developed. Article is written in Ukrainian

Modelling the Dynamics of the World Stock Indices (p. 197 - 202)
The article considers the issues of modelling the dynamics of the economic system, which is described by the aggregate of indicators from some major world stock indices. The practical possibility of application of methodology of dynamic factor analysis for researching such systems has been substantiated. The mathematical model, combining approaches of factor analysis and autoregressive estimation, has been developed. In contrast to the classical models of the vector time series analysis, a dynamic factor system is used to simulate evolution, which is more informative than the original aggregate of indicators. The basic calculated correlations of the constructed mathematical model and the direction of adaptation of the developed algorithm for solving a wide spectrum of forecasting tasks have been provided. Unlike well-known models, the proposed technique allows to define a certain interval of reasonable forecast values, the boundaries of which depend on the parameters of the model. The error in the control time interval, determined when comparing the averaged values of the forecasts for several indicators with actual index values, persists in the range of 1 – 2%, which confirms the high efficiency of the proposed methodology and the possibility of its use in research practice.

The Concept of Structural Changes and the Problem of Management of Enterprises Restructuring. Methodological Nuances (p. 212 - 220)
The article is aimed at clarifying the concept of structure as the main object of management in the process of restructuring industrial enterprises on the basis of philosophical conceptions of structure and ideas about the structure of the general system theory, as well as developing the methodological provisions on strategic management of enterprises restructuring. It has been shown that the concept of structure is extremely complex and not strictly formalized from the standpoint of the applied economy, which prevents the construction of a coherent, logically consistent theory and development of constructive methods of managing the restructuring of enterprises. In the article, with the use of schematic models of the high level of commonality, an analysis of the structure of functioning of industrial enterprises was carried out; the main types of possible structural changes at enterprises have been revealed; it has been shown that the process of restructuring in general is the process of making changes to the enterprise structure of the specified types. It has been concluded that the structural approach to solving the problem of management of the enterprises restructuring is reasonably required, constructive and needs some adjustment to the methodology and methods of implementation of the main stages and procedures of the strategic management of enterprise restructuring.

The Category of Competitiveness as a Generalization of the Concept of Economic Potential of Enterprise (p. 127 - 134)
The article is aimed at analyzing the known definitions of the concept of competitiveness, in order to substantiate the methodologically more rigorous formulation of the definition of this concept, to identify the logical links between the concepts of competitiveness and indicators of the level of competitiveness, on the one hand, and the notions of economic potential of enterprise and its level, on the other. It is shown, that the postulation of the level of achievement of the main purpose of functioning of economic objects in defining the concept of competitiveness comes into logical contradiction with the substantial notions about competitiveness and the known methodical approaches to the measurement of its level. The definition of competitiveness of enterprise as ability of enterprise to generate net income in competitive environment without external assistance on a long basis is proposed. Logical links between the indicators of competitiveness and economic potential of enterprise have been disclosed, indicating that assessment of competitiveness is a generalized estimation of the forecast trajectory of the economic potential of enterprise, and the existing methods of assessing the level of competitiveness of enterprise and its economic potential need to be substantially elaborated in order to fully reflect the main features of the indicated characteristics in the relevant assessments.

The Practice of Using the Discriminant Analysis of the Efficiency of Processes of Functioning of Agricultural Enterprises on the Basis of Indicators of the Constituent Parts of Performance (p. 135 - 141)
The article considers the practice of using the method of discriminant analysis to study effectiveness of the processes of functioning of enterprises on the basis of indicators of the constituent parts of performance on the example of specific agricultural enterprises of the grain products subcomplex. It is underlined that when using benchmarking (as a method of competitive analysis) in many cases when researching the processes of functioning and development of enterprises (in particular, agricultural) there is a need to distribute the studied objects into individual groups according to the main strategic priorities. It is specified that one of the methods used for such distribution is the classic discriminant analysis, which allows to define the quantitative boundary that distinguishes the group of enterprises-leaders from all other enterprises. It has been found that the determining factor in the use of the specified method is the choice of a number of indicators characterizing the objects and processes allocated by using benchmarking. This choice, in turn, requires implementation of an appropriate algorithms based on simulation. As these indicators serve the authors’ indicators of efficiency and scale product, selected as the constituent parts of the performance indicator, characterizing any process and its results from both the qualitative and the quantitative points of view. The authors’ own approaches to the method of grouping of objects and allocation of strategically important groups among them have been proposed. Article is written in Ukrainian

The Impact of Expenses of Budget Organizations on Economic Growth (p. 141 - 148)
It has been determined that budgetary policy has both the direct and the indirect impact on the rate of economic growth. According to the functional classification, the composition of expenses of budget institutions has been identified, their structure and dynamics in the period of 2007–2018 have been researched. A structural analysis of budget expenses in the context of economic classification was carried out, on the basis of which a specific group of expenses of budget institutions promoting the development of intellectual capital has been identified. The stochastic correlation between the rates of growth of own incomes and expenses of budget organizations on the development of human capital was investigated, and on this basis the potential of the budgetary sector in the context of financial autonomy has been estimated. An economic-mathematical model for determining the optimal composition of private investments, productive and non-productive budget expenses has been proposed. According to the built model, the following components of the budget expenses have been defined as productive ones, the growth of the specific weight of which in the overall structure leads to sustainable growth of the economy. Institutional barriers to increase the productivity of budget expenses were identified, considering their substitutionarity and complementarity. A correlation-regression analysis was carried out to determine the nature of impact of separate components of the budget expences on the economic dynamics. Article is written in Ukrainian

The Financial Leverage Effect: Problems of Use in the Process of Optimization of the Enterprise Capital Structure (p. 148 - 154)
The article is aimed at clarifying the feasibility of optimizing the structure of the company’s capital based on the effect of financial leverage for the simplest situation – in the absence of profit taxation and without considering the dynamic aspects, related to changes in the total volume and composition of assets. On the basis of use of the recognized theoretical provisions – the Modigliani-Miller postulates – the authors illustrate the fundamental difference of results of the capital structure optimization by the criterion of maximizing the profitability of equity, which stipulates use of the effect of financial leverage, and on the criterion of maximizing the value of the owners capital. It has been concluded about the disadvantage for owners of implementation in the above-mentioned static situation of any revision of the capital structure accompanied by an increase in the financial leverage ratio, as it does not lead to an increase in the value of enterprise, but only provides a threat to its decline, and worsens financial security. Building of any optimization models of the enterprise’s capital structure, including those based on use of the effect of financial leverage, has been recognized as not expedient in the considered situation.

Assessing the Country’s Financial Security (p. 155 - 161)
The article is aimed at assessing the level of financial security of Ukraine, using the instrumentarium for calculating the integrated indicators for each component, during the period from 2005 to 2016. As result of the research, a significant decrease in the level of banking security, security of the non-banking financial sector, as well as debt and budget security have been identified. There was also an unsatisfactory level of foreign exchange security during 2008–2010 and 2015, while in the course of 2006–2007, 2011–2012, in 2014 and 2016, the level was average. The integral indicator of monetary security during the researched period did not exceed the mark of 0,4 points, that is, its level did not reach even the average. In general we can note the average level of financial security in Ukraine in 2005–2007 and 2009–2013, but its level in 2008 and 2014–2016 was unsatisfactory. Prospects for future researches in this direction are improvement of scientific-methodical approaches to the assessment of financial security of the country and determination of ways and directions of increase of the level of financial security.

Assessing the Neoindustrial Factors of Development of Industrial City in Conditions of Decentralization (p. 162 - 167)
The article researches the neoindustrial factors influencing development of industrial city. Their quantitative assessment is carried out on the basis of use of the index method together with a multiplicative model which allows taking account of and harmonizing the low and high values of indicators, also determining the degree of conformity of the calculated index with conditions of reality. The index of development of industrial city is defined on the basis of three sub-indices: knowledge index, innovations index, information-communication technologies index. On the basis of calculation of the index of development of industrial city under influence of neoindustrial factors the low level of development of industrial city is defined. It has been determined that the level of innovative development is high and reaches 0,519, while the level of knowledge is lower, reaching 0,438. The general index of knowledge and innovations for Zaporizhzhya is 0,476, which demonstrates the insufficient level of the development of industrial city under the influence of the newest factors. It is concluded that the incomplete and inefficient use of potential opportunities results in a relatively low level of the development of industrial city from the point of view of the three-vector model of «knowledge ? innovations ? information-communication technologies». This requires the search for an efficient instrumentarium that will allow the development of city on the basis of positive impact of neoindustrial factors. Article is written in Ukrainian

The Conceptual Model of Calculating the Return Period of the Costs for Creation of the Enterprise’s Economic Security Service in the Short-Term Period (p. 167 - 173)
Determination of the return period of the costs, advanced for the creation of economic security service of enterprise during a year, involves consideration of interaction of the conditional money flow, accumulated for a certain number of months, and the constant costs. The main component of the constant costs are the annual depreciation deductions. The return period is considered as gross, net, valid, and specified. The gross (net, valid, and specified) return period is the time, wherein the gross conditional money flow, equal to the advanced costs, will be accumulated. The gross return period, taking account of the effect of time factor, is proposed to be defined as the ratio of annual depreciation deductions increased by the annual compounding coefficient to the conditional average monthly gross money flow, increased by the average monthly inflation index. As for the short-term period, a relationship between the gross, net, valid, and specified return periods of the costs, advanced to the creation of the economic security service, has been identified. The net (valid, specified) return period is equal to the gross period adjusted to the coefficient of excess of the gross conditional money flow, accumulated in the gross period, over the net (valid, specified) conditional cash flow.

The Statistical Hypotheses on Randomness of Factor Relations and Interrelations of Socio-Economic Processes (p. 133 - 138)
The models of factor relations and interrelations of socio-economic processes are based on the corresponding theoretical and economic provisions and hypotheses. In the presence of statistical data, analytical or econometric models (model systems) can be constructed. Checking of adequacy of the models commonly uses the Fisher Criterion, determination coefficient and other instruments. The econometric approach presupposes the presence of unaccounted factors in the model, which are assumed to be coincidental with certain law of distribution. The hypothesis of presence/absence of randomness in the interaction of factors is not put forward as such. The article considers the possibility of applying the econometric approach in general. The criteria for assessing the presence of the factor of randomness of relations and interrelations of time series have been developed. The method of certain intervals for estimation of character of relations and interrelations between the factors that characterize socio-economic processes is proposed. Simulation experiments confirming the capacity of the method of evaluating the action of the random factor in socio-economic processes were carried out. Prospect for further researches would be development of a common methodology for econometric modeling, taking into consideration the nature of interrelations and relations between factors.

The Substantiation of the Mechanism for Assessing the Usage of Fixed Assets at the Enterprises of the Mining and Processing Complex of Kryvbas (p. 160 - 167)
The article substantiates that the final results of the enterprise’s economic activity depend on the status and efficiency of usage of fixed assets, and increasing the efficiency of using them is one of the main and topical issues in the conditions of market relations. Of particular importance in this aspect is the functioning of enterprises of the mining and processing complex of Ukraine and the Kryvyy Rih iron ore basin (Kryvbas). It is determined that current approaches to the formation and usage of fixed assets of enterprise are predominantly of fragmentary nature in terms of innovation development and efficiency of usage of fixed assets and their components, and do not account the sectoral specifics of mining and processing enterprises.

The Program Implementation of the Task of Distribution of Vehicles with Fixed Surcharges (p. 167 - 173)
The article is aimed at mathematical and computer simulation of the transport task of distribution of vehicles with fixed surcharges, or the task with discontinuous objective functions. The main attention was paid to the building of a mathematical model of the situational optimization task, which is often encountered in transportation practice, but does not have a universal approach to its solution. For this type of transport task, both general content and mathematical staging, together with a concrete example of their solution, are provided. The authors have deliberately chosen for the task of distributing vehicles with fixed surcharges an example with a small dimension of transport routes. The purpose is to increase the visibility and simplify the consideration of issues of their mathematical modeling. The issues of computer modeling of such tasks are considered in the article separately. For the first time, a new approach to solving them has been proposed: not only by means of computer mathematics, such as Excel and MATLAB, but using the genetic algorithm of «behavior of bees’ swarm», which has showed the best result in terms of the number of iterations. That, in turn, allows to apply the latter algorithm for the tasks with larger dimensions. Article is written in Ukrainian

The Model of Management of Inventory with Fuzzy Triangular Demand (p. 174 - 179)
The publication presents the algorithm of building the inventory management model, provided that unknown demand for resource is modeled with use of fuzzy logic. The algorithm can be applied also for an innovative product or service, when history data on demand are absent. Thus, based on the observations of demand for such goods and on the basis of experts’ judgment, the predicted value of demand can be represented as a triangular fuzzy number. As a result, the values of the cost function of the inventory management system are respectively fuzzy numbers. For the defazification of this function, the method of median was used in the work, resulting in a real value function of the cost. To find optimal strategies for the operation of the inventory management system, the criterion of minimizing the cost function obtained by the given algorithm was used, which allowed to record optimal solutions of the problem explicitly. The theoretical material is illustrated by numerical examples. The obtained algorithm of search for optimum strategies can be used at developing the software for optimization of procurement at production place in view of absence of history of previous sales.

Modeling the Sectoral Structural Changes in the Region’s Economy (p. 126 - 136)
The methodical approaches to estimation of influence of factors on the structural changes in economy of region are formed. The influence of internal and external indicators-factors on the structural dynamics of economy of regions of Ukraine is estimated. The degree of correlation between the selected indicators-factors and the resulting indicator of economic development of regions is determined. Using the methods of correlation-regression analysis, a multifactorial model of change of the gross regional product (GRP) under the influence of internal and external factors of economic development is built. The model of polynomial regression of influence of the change of structure of employment by kinds of economic activity in terms of regions of Ukraine as to GRP is built. The system approach to the estimation of structural-dynamic transformations in the regional economic system on the basis of calculations of efficiency of the structural adjustment is suggested. The model of estimation of quality of the structure of economy on the basis of proportionality coefficient is built. Proposals on directions of changes in the economic structure and on methods of influence to overcome the structural instability in the region’s economy are presented. Article is written in Ukrainian

Determining the Competitiveness of Participants of the International Economic System in View of the Customs Factor (p. 149 - 155)
The article is aimed at identifying the reasons for changing the competitiveness of participants of the international economic system in view of the customs factor, as well as determining the equilibrium volumes of each participant’s product supply to the market. The research made use of the methods of mathematical modelling. As a result, the intervals of competitiveness of both domestic and foreign producers when selling products in the national market are defined. It is determined that when the self-cost of production of domestic producers increases so much that foreign producer becomes competitive in terms the national market, the volume of products in the national market decreases. However, this decline in output is not as drastic as it was when foreign producer had been forced out of the market, that is, the presence of foreign producer smooths the decline in output. It is noted, that at increase of the self-cost of production of domestic producer the latter becomes uncompetitive, and the national market deals only with the production of foreign producer. Scientific novelty – it is proved that one of the key factors that ensure competitive advantage of the produced products is the scale of production, which can be achieved by expanding the market and reducing the self-cost of production.

Improving the Methodology of Assessing the Competitiveness of Enterprise by Means of the Procedure of Determining the Optimal Number of Assessment Factors, in View of the Necessary Order of their Integration (p. 156 - 161)
In modern conditions of the market economy there is a necessity in application of the most modern methods which would allow to achieve maximal efficiency in achievement of the greatest profit by enterprise. One of the elements of such a methodology is the assessment of competitiveness, directed towards identifying the factors contributing to the positive dynamics of the enterprise’s activity. The article is aimed at the theoretical substantiation of an integrated approach in assessing the competitiveness of enterprise and developing recommendations for its improvement by performing such functions as the selection of necessary factors, in view of the necessary order of their integration. In calculating the competitiveness indicator with use of the «polygon of enterprise competitiveness» there is a problem of accuracy of the obtained indicator. Researches on calculations of competitiveness of enterprise under different order of use and quantity of the chosen factors have been made, and the result has shown various totals. To solve this problem, a procedure is proposed to determine the optimal number of assessment factors, taking account of the necessary order of their integration. The main purpose of applying the assessment of factor is to determine the relationship of the order, established between factors as to the importance level. On this basis the place (or rating) of each factor from the given aggregate, subjected to assessment, is determined. Article is written in Russian

Calculating the Credit Limit for Individual Borrower on the Basis of Logit-Model (p. 162 - 169)
The research is aimed at developing an algorithm for valuation by credit institution of the credit limit for a natural person-borrower, with regard to his socio-demographic characteristics, using the logistic regression tools. The improvement of the procedure for valuation of the solvency of an individual borrower is to integrate an empirical approach to the definition of solvency (based on the ratio of official income and expenditure of an individual) with the economic and mathematical methods, allowing to consider the available retrospective data of the financial institution about borrowers and to identify statistically significant regularities. The key role in the algorithm of estimation of credit limit is occupied by development of the logit-model for classification of borrowers for classes of «reliable» and «unreliable», the classification force of which will be to a large extent determinative as to the predictive quality of defining the amount of the credit limit. The publication presents an example of application of the logit-model for credit scoring, including quantitative and qualitative variables, with the help of which the socio-demographic characteristics of borrowers are described. The procedure of using the proposed algorithm is illustrated on the basis of such logit-model. Article is written in Ukrainian

The Simulation Model of Management of Competitiveness of the Industrial Complexes of Regions (on the Example of Slobozhanshchina) (p. 169 - 176)
In the publication, the author builds an economic-mathematical simulation model of management of competitiveness of industrial complexes of regions. Comparison of two reliable regression models of Slobozhanshchina has showed that, with consideration of the balance indicators, all variables provide a commensurate positive contribution to the resulting indicator; otherwise, only capital investments have a positive effect on the final result, and the innovation activity of industrial enterprises and financial results before taxation can be considered extremely unsatisfactory. The functional relationship between the volume of sold products, goods and services and the financial results before taxation is clarified. It is concluded that the more is the functional dependence between the volume of realized industrial products and the financial results before taxation, the better are the results of economic activity of the regional industrial complex. Therefore, when building a strategy of management of competitiveness of the industrial complex of region, one should consider these levers of influence. Article is written in Ukrainian

The Methodical Approach to Assessing the Economic Security of Ukraine (p. 176 - 181)
The aim of the article is to improve the diagnostic instrumentarium for assessing the economic security of the country. One of the biggest problems of economic security in Ukraine is the presence of regional developmental imbalances, therefore, it is proposed to assess the level of economic security of the country by calculating the integral indicator, which should be understood as a generalizing macroeconomic indicator that comprehensively characterizes the current status of national economy security in a regional context. The assessment of the level of the country’s economic security is proposed to be carried out with a hierarchically constructed system of indicators, which includes integral, complex and partial indicators. Diagnostic instrumentarium for assessing the economic security of the country implies the use of correlation and taxonomic analyses, as well as the scaling method, which allows determining the level and disproportions of regional development and can serve as a basis for developing a strategy to ensure the economic security of the country together with its regions.

Improving the Methodology of Estimation and Analysis of the Level of Economic Security of Enterprise (p. 184 - 191)
The research is concerned with finding ways to improve the methodical approach to estimation of economic security of enterprises on the basis of a set of analytical methods and models that allow improving the performance of system of enterprise management, defining the directions of stabilization of economic security of enterprise, reducing risks of the threat of occurrence of financial crisis at the enterprise and ensuring its proper economic viability. The proposed approach consists of four steps that complement each other and provide a comprehensive estimation of the level of security of enterprise, determination of the class of enterprises in terms of economic security, as well as estimation of the level of financial security by assessing the likelihood of enterprise’s bankruptcy. The approach was implemented on a sample of twenty enterprises of the oil and gas industry complex of Ukraine, which allowed to identify enterprises with low level of security and to predict the likelihood of bankruptcy for their typical representative. The results of the assessment for the enterprises in the focus group showed a predominantly low level of economic security, which is primarily due to the unstable political situation and a low level of development of the industry branch.

The Scenario Modeling of Households’ Activities in the Overall Economic Structure of the State (p. 146 - 153)
The main aim of the publication is researching the activities of household sector in the overall economic structure of the State using the modern economic-mathematical methods and models of macroeconomic processes. The research showed that households’ expenditures have a significant impact on the aggregate output of products (AOP), especially for industries where their share is the largest. The results of a scenario modelling of the dependency of the AOP on households with regard to industries, using the cross-industry balance model, suggest that the proposed methodology can be used to plan and forecast economic growth in terms of development of scenarios of their impact on the overall economic result. It is determined that the main factor of adaptation of households in conditions of economic instability is small-sized entrepreneurship as a source of formation of incomes in the form of profit and mixed income. Ensuring this process is meant to increase the level of human capital by increasing consumer spending in the spheres of education and health. Article is written in Ukrainian

Causal-Сonsequential Links Between the Indicators of Innovation and Investment Activity of Region (p. 129 - 135)
The current world-wide development of regionalism focuses on the scientific argumentation of the choice of methods and instruments for efficient management of region. During the reform of the decentralization of power in Ukraine such studies are necessary for exploration of practical application by regional authorities. The author used the the Grainger’s test to explore the existence of causal-consequential links between two groups of indicators of regional activity, both innovation and investment. According to the results of the test the division of regional indicators of these groups as to presence of a link: its direction (one-sided, inverse) and strength (strong, weak) is made. The Grainger’s test provides an opportunity to predict the interrelationship and interconnection for a period of up to three years, which can assist in shaping the region’s measures of impact on innovation and investment and managing the economy of region as a whole.

The Volatility of Price Movements When Changing the Export-Import Balance (p. 205 - 211)
The present publication is concerned with the problem of analyzing the pricing mechanism when carrying out export-import operations. As a basic model is suggested the dynamic version of the traditional monetarist balance by I. Fischer – the main correlation of quantitative theory of money. The dynamic formalization of the model has a representation in both discrete and continuous temporal forms. The peculiarity of the investigated model is the linear nature of dependence of functions of volumes of exports and imports from the internal price on commodity production. This hypothesis generates the structure of the discrete dynamic model in the form of quadratic (logistic) display. A substantive analysis of the stability of equilibrium positions is done with indication of all possible types of dynamic behavior, e.g. limit cycles and chaotic modes. The substantial economic interpretation of the main bifurcation parameter is provided. For a continuous version of the model, explicit expressions to change the price in the temporary area are obtained and the fact of the presence of a catastrophic «crease» type is determined. For the analysis of behavioral properties of the researched model, the methodology of description of self-organizing economic systems with consideration of the corresponding synergistic effect is used.

The article deals with modeling and forecasting the population of Ukraine by time series. It is shown that time series analysis is a complex, multicomponent econometric task which does not have a universal approach to its solution. This is due both to the diversity of methods of and approaches to time series analysis which were developed over time and to the specifics of time series data. For example, the authors of the article worked with a univariate nonstationary time series, therefore, the approaches and methods presented in the article are not recommended for time series with different properties. The article has an enormous practical value, since it discusses in detail issues of computer modeling of tasks of the kind. The carried out analysis of the literature has shown the relevance of the problems considered, among which particular attention should be paid to the choice of the ARIMA model, data visualization, and forecast accuracy.

Simulating and Forecasting Periodic Behavior of a Discrete Time Series Using the Moving Average Method (p. 106 - 110)
A new method for simulating and forecasting a discrete time series using the moving average method is proposed and substantiated. The idea of the method is to use the latus rectum as a quantitative estimator of the shape of a parabolic segment of a time series trend. Since the actual number of values of this indicator in terms of nature of its periodicity resembles an array of innovative buckets, there arose an idea of using the foci of parabolic segments which approximate these buckets. To build the forecasts, the simplest method of double moving averages of the third order was chosen. Using the moving average method, it is possible to obtain not only forecasts of points or intervals but also more complex ones, e.g., those of parabolic segments. The method of forecasting with the help of moving averages has provided an opportunity to give a generalizing picture of the changes in the process being studied, as demonstrated by the example of the indicator “Innovative Activity of Ukrainian Enterprises”. It has made it possible to predict the intensification of innovation in Ukraine for the period up to 2024. Article is written in Ukrainian

The Methodological Bases for Developing Ukraine’s Aggregated Macro-Economic Model Based on a System of Simultative Equations (p. 98 - 105)
The objectives of the article are the following: building and evaluating with use of a system of simultative equations of an aggregated macro-economic model of Ukraine’s economy, taking into account the level of shadowing; carrying out a scenario analysis based on the model to define the key instruments of the State-based regulation aimed at reducing the shadow sector and achieving macro-economic stability, taking into consideration possible external and internal destabilizing factors and risks. This approach to modeling allows quantifying the interaction of key macro-economic indicators of the Ukrainian economy, but also applying a wide range of scenario analysis to define efficient instruments of the State-based socio-economic regulation both in the short and long perspectives. In order to demonstrate the practical possibilities of the built macro-model, a forecast of the main macro-economic indicators is calculated under the terms of a baseline scenario and several possible scenarios for further economic development are analyzed (in particular, in the assumption as to further growth in average wages and volumes of cash outside banks), as well as an assessment of the impact of such a change on the level of economic shadowing and employment is carried out, indicating invariance of the tendencies of other macro-economic indicators of the model. Scenario analysis and quantification of the relationships between the model’s variables indicate the sensitivity of employment, level of shadow economy, inflation, exchange rate, interest rate and GDP to changes in the macro-economic environment. Prospect for further research is to expand the developed aggregated macro-model of simultative equations by adding other sectors, in particular fiscal, tax, etc., to more accurately reproduce the functioning of the country’s economy as a whole.

Substantiation for Using the Moving Focus Method to Simulate and Predict the Time Series Form (p. 123 - 129)
The predicting of economic factor using the moving focus method is substantiated. The method is based on the use of the focal parameter as a quantitative valuer of the form of parabolic segment of trend and is illustrated by the example of the factor of «Innovation Activities of Enterprises of Ukraine». The actual set of values of this indicator by the nature of cyclicity resembles the sequence of «innovative» buckets (jezves). The method uses the focuses of the parabolas’ segments that approximate these buckets. The simplest method of moving averages is used. The substantiation required the introduction and use of a new concept - «temporary series skeleton», which is a complex of pairs of the empiriametric models of the adjacent branches of trends of jezves. The application of the moving focus method allows to draw the following conclusion: if for the years of 2018 and 2019 the factor of «Share of Ukrainian Enterprises that Were Innovative» gains values of 18,40% and 25,50%, then, starting in 2020, the values of the factor are predicted to fall to 18,35% and 16,09% in 2021 and 2022, accordingly. Thus, at the interval of 2019-2022, the form of the growing trend (at a rate of 4,90x - 9868,78) is predicted to change downward (at a rate of 4,56x - 9214,28). Article is written in Ukrainian

The Models of Analysis of Regional Potato Market (p. 130 - 135)
The publication presents the results of a research on the existing practice of analyzing the regional potato market in terms of production and consumer potentials. By examining existing approaches to the analysis of the regional potato market, as well as the use of economic analysis techniques together with an applied econometric instrumentarium, it has become possible to offer the authors’ own approach to the solution of the task of analysis of both the production and the consumer potentials of the regional potato market on the example of the regions of Western Ukraine. Building-up and econometric analyzing of the models of dependence of potato production and consumption on key factors in each of the regions of Western Ukraine allowed to track the cause-and-effect relationships between the main parameters of the researched food market in the context of ensuring the region’s food security. The calculated projections of the use of the resource capabilities of the regional potato market and the consumption of this type of food give every reason to conclude about the expected slight increase in use of the production potential against the backdrop of declining use of the consumer potential. This is explained due to a decline in real consumer capacity against the background of the growth of the production self-cost of potatoes in all categories of farms. Practical use of the developed approach in the process of analyzing and calculating projected efficiency values for the use of the production and the consumer potentials of the regional potato market (with appropriate model calculations and taking into account the possible lag effects because of changing economic conditions) will potentially allow a qualitatively new approach to the formation of mechanisms for ensuring, analyzing and monitoring the food security of Ukraine’s regions.

A Methodology for Macro-Economic Research on Social Tension: Analysis, Evaluation, Diagnostics (p. 105 - 114)
The publication is aimed at researching social tensions in the European Union on the basis of the application of economic-mathematical modeling at the macro-economic level. The publication discloses theoretical approaches to such phenomenon as social tension at the macro-level, forms an indicative space, analyzes the influence factors, the mechanism of formation, and stages of development. The current macro-economic status of social tensions in the EU countries is researched. A comprehensive scheme for evaluation and analysis of social tensions in the EU countries is developed, containing implementation of the four main stages according to the selected factors-indices. A social tension index for the EU countries is formed, the extent of the influence of factors on the social tension index based on methods of correlation and regression analysis is identified. A model of evaluation of the level of social tension has been built to identify regularities of development over a certain period of development. In order to identify groups of countries with similar factors of social tension and to detail the resulting integrated scale, a model has been developed to classify countries, applying the Ward’s method, by the level of social tension using Gap-statistics and k-averages. Based on the use of the neural network learning algorithm, a group of countries in which also belongs Ukraine has been found, showing relation to the factors of social tension formation. The function of forecast provisioned by the functional of neural network is used, according to which Ukraine falls into a cluster with a high level of social tension, that is, has a similar background for functioning of the mechanism of social tension with such countries like Bulgaria, Romania, Macedonia, Serbia, Turkey and Montenegro. Thus, the proposed methodology for macro-economic research on the level of social tension is an effective tool for integrated diagnostics, which will allow to focus on the development of adequate and effective strategies for prevention of increase in social tensions and to minimize the threats associated with it in a timely manner.

Model of Monetary Policy Parameters Formation (p. 115 - 121)
The publication presents results of the carried out analysis of existing Western and domestic macro-economic models, which form the basis for determining the key parameters of monetary policy of the central banks in the respective countries. A study on the existing approaches to the formation of monetary rules of central banks in both advanced market economies and countries with emerging markets shows limited possibilities of efficient use of the classic J. Taylor rule and its modifications to form the Monetary Policy of the NBU. The carried out analysis of macro-economic indicators, as well as the use of the econometric analyzing methods, allowed to propose a possible approach to the problem of forming a monetary rule and developing a model of behavior of the NBU regulation of the basic macro-economic indicators together with setting the interest rate. A simultative model built on the basis of quarterly information for 15 reporting periods, displaying the main relationships between endogenous and exogenous variables, which determine the rule of monetary policy of the NBU, allowed to track the direction and nature of the causal relationships between the basic macro-economic parameters in the context of setting the interest rate by the NBU. The calculated forecast values of endogenous variables of the developed model, namely: consolidated balance, exchange rate, real GDP, real wages, interest rate of the NBU, consumer credit volumes, and consumer price index allowed to identify manageable tendencies in changing the values of these indicators and to conduct an analysis of possible scenarios of a macro-economic situation evolving. Practical use of the proposed approach (in the process of analyzing possible scenarios for the evolvement of key parameters of monetary policy and calculations of the forecast values of interest rate, consumer price index and other interconnected macro-indicators with carrying out the appropriate model calculations, the development of a structured multi-sectoral model, as well as taking into account the possible lag effects of changing economic conditions and the impact of qualitative factors on macro-indicators) potentially will allow a qualitatively new approach to the formation of mechanisms for analyzing and forecasting the monetary policy of Ukraine.

Development of Risk Measurement Instrumentarium in Modeling of Uncertainty Using the Fuzzy Set Approach (p. 149 - 156)
The article is aimed at developing a methodical apparatus for risk measurement using the fuzzy set theory in order to formalize uncertainty. The problem field of research is limited to a situation where an economic indicator that serves as a decision-making criterion is described by a fuzzy number, understanding the latter as a fuzzy value with normal and convex membership function. Based on the interval (by the levels of membership) method of presenting a fuzzy assessment of the criterion indicator, the publication considers such indicators of the risk degree as average absolute deviation, average range of variation, half-deviation (average absolute half-deviation), the average one-sided variation. The versions of the last two indicators, formulated in the study in terms of the fuzzy-set methodology, are the result of the refinement of their prototypes proposed in previous publications of the author. As evidence of the logical correctness of the revised versions of the half-deviation and the average one-sided variation are the corresponding equalities, which reflect the relationship of these indicators with the indicators of the average absolute deviation and average range variation, respectively. In general, the results of the proposed study should be regarded as separate components of a single system of instrumental means for quantifying the risk degree in a fuzzy data situation, the formation of which has not yet been completed and suggests further development.

Measuring the Efficiency of the Processes of Functioning of a Component System Based on the Models of the Efficiency Constituents: The Energy Aspect (p. 102 - 110)
The article is aimed at improving the development and disclosure of the methodology for measuring the efficiency of the processes of functioning of a component system based on the models of the efficiency constituents and the use of advantages and costs of processes in their aggregate products in terms of energy approach. Three types of performance indicators of a component system, proposed in previously published works by the authors, were analyzed as follows: the ratio of the processes’ aggregate product indicators to the cost indicators; the ratio of the processes’ net product indicators to the aggregate product indicators; average geometric values of these two types of indicators. New approaches have been proposed to the method of measuring newly formed authors’ own performance indicators of a component system in terms of the use of advantages and costs of processes in their aggregate products. Novation in this sense is that the approaches we have proposed address the problem of simultaneously measuring the efficiency of the processes of functioning of a component system (using the performance indicators of the specified three types) irrespective of the units of measurement of their aggregate, net products and costs, as it all comes down to a disproportionate unit of measurement in the form of advantages and costs of processes in their aggregate products, and the average performance indicators of the processes of functioning of a component system (arithmetic and geometric) to some extent can be considered characteristics of the relevant indicators of the efficiency of the process of functioning and the system itself. Underlined is the following: since the value of the authors’ own indicators of aggregate products, products as costs and net products of the subprocesses within the process of functioning of system are equal to the values of the energy indicators of these products, research of certain processes (including the processes of functioning of a component system) based on the indicators for these products means that they are scientifically considered in the energy aspect. Examples show the practical implementation of this methodology. It is noted that the obtained results can be used to make certain managerial decisions regarding both the system components and the system (its status, structure, behavior, etc.) as a whole. Further research is planned to be linked to the identification of the role played by measurements of the newly formed indicators of the processes of functioning of a component system and the suggested methodology in the SEE analysis and SEE management, carried out by the authors.

Intensification of Management of Economic Behavior of Enterprise in Competitive Markets (p. 110 - 118)
The article considers the intensification of the process of management of the economic behavior of enterprise in competitive markets. The system of management of the economic behavior of enterprise should be guided by the pace of development of scientific-technological progress, be necessarily related to the mechanism of the enterprise’s activities and is aimed at improving its activities and management methods. Applying the priority management practices for an enterprise should be based on the integrated use of a system of economic laws and managerial principles. Intensification of management of the economic behavior of enterprise in competitive markets is formed by means of certain instruments, methods and levers that interact with each other and constitute a holistic formation, produce an economic effect. Methods of measuring the intensification of management system of the enterprise’s economic behavior are proposed to be applied as most socio-economic indicators, formed under the influence of many factors rather than one. A model of correlation-regression analysis has been proposed, based on a group of factor indicators, namely: production costs; volume of products produced; value added by production costs; capital investment in the enterprise; number of enterprises in the industry. The findings of the research are that the greatest impact is the value-added indicator related to production costs. Measures to intensification of enterprise in competitive markets have been proposed. The main conditions for the successful implementation of the intensification of enterprise management in competitive markets have been defined through: improving the use of all types of resources and predicting the possibilities for their replacement with better ones; intensification of the introduction of innovative models for the formation of organizational behavior of enterprise in competitive markets; improving organization of production to identify bottlenecks and identify reserves; introduction of a system of measures to improve managerial decision-making based on the introduction of information technologies inherent in the digital economy.

The Sustainable Level of Innovation Potential as a Strategic Priority Task for Operation of Industrial Energy Producers (p. 118 - 125)
The article defines that every industrial energy enterprise in the structure of the production industry should develop an effective strategic plan for its innovative development, directed towards achieving a balance between its own solvent demand, existing supply volumes from scientific organizations and the investment opportunities. Taking account of the forecast of such kind, enterprises must define which production technologies should be developed and which should be abandoned. The increase of innovation potential should be preceded by projections of investment volumes and aggregate financing for the development of science and technology. It is concluded that the achievement of strategically innovative goals depends directly on the clear coordination of interaction between the various functional structures of industrial energy enterprises, rapid response to legal novations and the current internal situation. At the same time, an equally important forecast is both the external, aimed at verifying the compliance of economic results of industrial enterprises and a certain level of innovation potential with existing adaptive norms, and the internal, purpose of which is to ensure the implementation of innovative decisions, as well as to prevent undesirable consequences when changing the innovation-investment norms. Solving the related problems and shortcomings of the strategic system will help stimulate entrepreneurial production activity, increase business and investment innovation activity of industrial energy enterprises, as well as stimulating scientific-technological progress, technological renewal of production and, as result, the entry of national industrial enterprises into the global market of high-tech products.

Priorities to Improve the Costs Efficiency of Budgetary Institutions (p. 115 - 121)
The role and place of costs policy in the modern system of financial regulation of budgetary institutions is defined. The priorities facing the national system of budgetary institutions are identified, taking into account the need to strengthen its effectiveness and efficiency, including in the part: creating conditions for increasing the economic independence of budgetary institutions based on the replacement of estimated funding for end-to-end budgeting; updating the institutional mechanisms for financing and co-financing of socially important services; increased transparency and publicity of activities; introducing a system for evaluating the quality of services provided; introduction of an institution of effective public financial control at all stages of the management cycle, starting with planning. A methodology for evaluating the socio-economic costs efficiency of budgetary institutions is proposed, including the definitions of relative fiscal autonomy and of the decentralization level of the system of financing for the network of budgetary institutions, which can be used to characterize the compositional structure of financial policy in the sphere of costs. The role of fiscal decentralization in financing the costs of social development is defined. The specifics of use of the program-targeted method in financing the activities of budgetary institutions are characterized. Ways to improve the cost efficiency of budgetary institutions in the spheres of education and public health are suggested. Article is written in Ukrainian

Designing a System Dynamics Model of Shadow Wage Formation in Ukraine (p. 122 - 128)
The formation of the shadow wage in Ukraine is a major problem and a threat to economic growth. According to different valuation methods, the shadow economy in Ukraine ranges from 35% to 54% of GDP, and the shadow wage is estimated at 18% of GDP. The general scheme for tax evasion by businesses is to informally pay cash to workers in “envelopes”, which results in a large amount of cash in the economy and, as a consequence, further opportunities for tax evasion. Despite the urgency of the current issue for Ukraine and a large number of works by Ukrainian and foreign scientists dedicated to finding positive and negative features of the existence of shadow wages, there is still a lack of research that determines the formation of shadow wages through the use of economic and mathematical tools. Based on that, a model of shadow wage formation using the system dynamics method was constructed, which takes into account such factors as the amount of cash in the economy and the size of the minimum wage. Based on the modeling results it was found that raising the minimum wage would reduce the share of the shadow component in GDP. Taking that into consideration, conclusions were drawn regarding the first objectives of government policy, which should aim at creating opportunities for economic growth and reducing the amount of cash in the economy in order to lower the size of the shadow sector in Ukrainian economy as a whole.

The Economic-Mathematical Modeling of the Optimal Structure of Investment of a Mining and Dressing Enterprise (p. 108 - 114)
In accordance with the task of substantiating the economic-mathematical model and the method of optimizing the main directions of investment to maintain the raw-materials and technology base of a mining and dressing enterprise, their current status and problematic issues of production are analyzed. The main areas of investment activity are highlighted and their connection with the major resource and technological facilities of the enterprise’s production infrastructure is displayed. A stochastic factor analysis is carried out and the closeness of investment investments by the areas with the main economic indicators of the enterprise as a whole is determined. The most acceptable effective indicator for the working conditions of a particular enterprise is substantiated. Correlations between net profit and volumes of investment in technical rearmament, major repairs to machinery and equipment and capital construction are determined. The nature and degree of joint influence of directions of investments on net profit are analyzed. A criterion for evaluating the efficiency of investment use is proposed and an economic and mathematical model is developed. The method of optimizing the structure of directions, which is the method of dynamic programming, is substantiated. The model is adapted and implemented in the working conditions of a typical mining and dressing enterprise. The results of the efficiency of implementation of the optimal structure of investment directions are presented. For the working conditions of a particular mining and dressing enterprise, an optimal structure is determined that, in comparison with the actual, allowed to get a significant increase in net profit. The possibility of expanding the application area of economic-mathematical models together with the methods of optimization of this type to solve other production tasks has been indicated.

Modeling the Occurrence of Global Financial Crises in the System of Financial Security of Countries (p. 75 - 82)
The publication is aimed at developing and approbation of an economic-mathematical model for controlling the occurrence of global financial crises on the basis of the implementation of control points of the macro-economic indicators of financial crises. Based on a retrospective study of the history of global financial crises and an analysis of scientific sources, the main macro-economic indicators that can signal the development of financial crisis are allocated as follows: balance of payments; ratio of external debt to the country’s GDP; exchange rate volatility; ratio of the country’s international reserves to imports. An economic-mathematical model for controlling the occurrence of global financial crises by implementing the control points of macro-economic indicators of financial crises, which can become the basis of the formation of systems for early warning of global financial crises to ensure the financial security of countries, has been proposed. The model allows monitoring and calculation of the main assessment indicators, forming an information base for the development of managerial solutions to prevent the onset of financial crises or reduce negative consequences due to their early detection. The practical approbation of the proposed model was carried out on the example of developed countries and developing countries, which play a systematically important role in the world economy, as well as on the example of Ukraine. A matrix of compliance of the optimal values of the main macro-economic indicators of financial crises has been built and the most likely sources of a financial crisis have been identified.

The Data Mining Technology Applications for Modeling the Unevenness of Socio-Economic Development of Regions (p. 82 - 91)
The article is aimed at developing models for reduction of the information space for the assessment of the socio-economic development of Ukrainian regions (SER), as well as allocating the factor groups of indicators that are of particular importance for improving the efficiency of formation and decision-making in the elaboration of the development strategies of regions. The carried out monograph analysis, systemization and generalization of modern scientific developments of domestic and foreign scholars allowed to determine the existence of a number of approaches to the definition and evaluation of the uneven socio-economic development of regions and the absence of a single base of assessment indicators of the SER. As a result of the study, a model to reduce indicators for evaluating the uneven socio-economic development of Ukrainian regions by Data Mining methods is developed, in particular by the principal components method, which allows to significantly narrow the system of estimates. As a result of the carried out modeling, the degree of influence and load of uneven indicators in the context of individual factor groups of the SER indicators in accordance with their principal components is determined. Prospects for further research in this direction should be the development of models for the classification of the SER statuses and forecasting the level of unevenness of the SER on the basis of the proposed complex of models for assessing the asymmetry and unevenness of regional development; forming a system of directions and the most significant strategic levers of regional development. The obtained results will allow to scale models according to the data of the European Union countries, which will serve as a basis for improving models of equalization of the asymmetry of the macro-regions development.

Methodology for Forming a Balanced System of Regional Differentiation Indicators (p. 133 - 142)
A step-by-step model of forming a balanced factor system of regional differentiation indicators in terms of the canonical correlation system is proposed. The canonical correlation relationships are researched between groups of source variables for the regions of Ukraine for 2015–2019 using the Statistica PPP. The main purpose of the research is to implement the methodology of canonical correlations by identifying the object of research in two characteristic spaces; maximizing communication (spatial display of the object); reducing the amount of raw data (the possibility of eliminating irrelevant factors). The selection of the most informative variables by the characteristic of the close relationship between two sets of variables and the content of the researched processes in dynamics is made by analyzing the structure of canonical variables and the magnitude of canonical correlations. The build up dynamic models of canonical correlations for the formation of a balanced factor system of regional differentiation indicators allow a more precise and logical implementation of meaningful interpretation of the obtained results in comparison with other multidimensional methods. According to the results of the research on forming a balanced representative system of indicators, the following sets of factors have been formed: the set of the most significant factors, the set of significant factors, the set of essential factors, and the set of non-essential factors. The methodology of canonical correlations is applied, which extends the possibilities of formation and research of interconnections of different phenomena and processes in socio-economic systems of different level of hierarchy as a result of involvement in the process of analysis of systems of a large set of studied factor and resultant indicators in one set, providing a fundamental basis for forming a balanced factor system of indicators of regional development and differentiation, both in spatial and temporal, dynamic context, which will improve and upgrade implementation of development strategies and will reduce the regional unevenness.

Using the Economic, Mathematical and Statistical methods in the Study of Mesoeconomic Dynamics (p. 143 - 149)
The article is aimed at practical applying the instrumentarium of economic, mathematical and statistical methods to improve the efficiency of managerial decisions in the context of the development of region. The article examines the components of regional development, defines indicators that characterize the status of the specified components, and provides their dynamics for the period of 2006-2018. Using the instrumentarium of correlation analysis, the density of the link between these indicators and the gross regional product (GDP) as an indicator of regional development is defined. The most influencing factors of regional development are discovered, providing an opportunity to substantiate the directions of dynamic positive mesoeconomic transformations. In particular, it is noted that the change in the real GDP index is most affected by the level of employment of the population, the share of innovative technologies introduced in the region during the relevant period, as well as the volume of consumption of fixed capital. In other words, the most influencing and controlled factors in regional development determine the amount of labor and capital resources involved, as well as the level of technological order. Using the regression analysis, a model of regional development has been built, with the independent variables being the previously identified factors that cause the most significant influence. It is proved that this model meets the criterion of adequacy, and therefore can be used in the subsequent forecast calculations to substantiate the decisions regarding the economic development of Luhansk region.

Research on Causality Between System Risk and the Indicators of Development of the Real Sector of the Economy in Ukraine (p. 176 - 182)
The stable functioning of the national financial system creates objective conditions for increasing the market capitalization of economic entities, increasing the inflow of foreign investment, improving the business climate in the country, as well as increasing the rate of GDP growth. The authors of the article are convinced that the financial and real sectors of the economy are closely related, and therefore it is possible to determine the principium of crisis situations by analyzing the causal relationship between these processes. Granger’s test, which involves the evaluation of auto-regression equations, was chosen as a methodical instrumentarium. To characterize the level of system risk in the country, the financial stress index was chosen, while the status of development of the real sector of the economy was proposed to be analyzed on the basis of the volume of exports of goods, the volume of imports of goods, the index of industrial production, the volume of retail turnover of enterprises, the index of agricultural production. As the informational base of the research was selected the monthly data for the period from April 2008 to December 2019. At the preparatory stage of the research on causality between the level of system risk and the indicators of development of the real sector of the economy, the time series was tested for stationarity, using the expanded Dickey–Fuller test and the stationary time series were converted with the help of the operator of the first and second differences depending on the variable. As a result of the empirical study, it is determined that the cause of the worsening of crisis phenomena in the real sector of the economy is precisely the effect of system risks. Prospect for further research in this direction is to evaluate the extent of the impact of system risks on the status of socio-economic relations in the country. Article is written in Ukrainian

Regression Analysis of the Impact of Demographic and Economic Indicators on the Status of Pension Provision in Different World Countries (p. 183 - 189)
The article is aimed at studying the effect of impact of demographic and economic indicators on the status of pension provision in 54 different countries of the world for 2010-2019. In the analysis and generalization of scientific works of domestic and foreign scholars, it was found that much attention is paid to the dynamics of expenditures and incomes of pension funds, but not taken into account (sufficiently) is the specific numerical influence of the factors, which can lead to a reduction or increase in the expenditures and incomes of PF. Therefore, it is important to research the effects of the impact of economic and demographic indicators on the financial status of PF in different countries. Using the regression analysis, the article analyzes the impact of the increase in the coefficient of age dependency, rate of pension contribution, unemployment rate, GDP and other indicators on the dynamics of expenditures and incomes of pension funds of different world countries, applying the least square method. The fixed-effect panel study method and heteroskedatric standard errors are used to check the reliability and sustainability of the results, which are clustered at the country level to account for successive correlations. Results are the average effect of impact for the total number of observations, the aggregate effect for the specified unions and organizations and a separate effect for Ukraine. According to the author, the previous pension reforms were not effective enough, given the status of Ukraine’s pension provision, as some procedure for introducing reform was not followed and the necessary resources were not adequately prepared. Therefore, a phased scheme is proposed to introduce a reform, to improve the status of pension provision, and ensure its socio-economic efficiency. Article is written in Ukrainian

The Integral Assessment of the Financial Status and Creditworthiness of Communal Enterprises in Ukraine (p. 116 - 122)
The article is aimed at developing a methodical approach to the integral assessment of the financial status of communal enterprises using the multidimensional statistical analysis method, since a comprehensive assessment of the activities of communal enterprises in the industry, which top the rating, will allow to use their achievements to solve the problems of enterprises-outsiders. It is concluded that the methods of calculating integral indicators presented in the Regulations developed by the NBU and the Ministry of Finance of Ukraine do not adequately reflect the true financial status and level of creditworthiness of enterprises. An approach to the integral assessment of the financial status is proposed, which involves building up a model of an integral index of the financial status of the enterprise; introduction and improvement of the information system for monitoring the financial-economic activities of enterprise; organization of a continuous comprehensive assessment and monitoring the main indicators that characterize the enterprise’s financial potential. The main stages of building up an integral index model using the main component method are described. An integral index, which characterizes the financial status of communal enterprises, is calculated and an industry rating of water supplying communal enterprises is compiled, allowing to respond in a timely manner to the deterioration of financial potential in the development of anti-crisis management solutions for enterprises-outsiders. Further research suggests improving the model through repeated testing for communal enterprises in various industries. This will allow to determine the final set of indicators to form the integral index. Article is written in Ukrainian

Managing the Business Systems of the Flexible Associations of Corporate Structures Based on Critical Parameters (p. 135 - 144)
The article is aimed at developing and researching a conceptual methodical approach to defining the critical parameters of economic activities of business systems to manage the flexible associations of corporate structures (ACS). It is shown that in the conditions of modern economic activity, which is exposed to the factors of market uncertainty, the definition of critical, or marginal, indicators of the parameters of the business systems of the ACS is of particular importance. This is necessary, as any kind of resources of the business systems of the ACS are always limited. At the same time, the efficient use of all available limited resources determines the size of the area of their spectacular use, or the area of flexible management of a corporate association. Based on the analysis of published works, it is identified that the problem of complex accounting of the interaction of costs of all types of economic activities to be accounted for in the business planning of industrial production by the ACS, is not solved to determine the critical parameters. The analysis of the limitations of the margin analysis method for flexible management of the ACS in the face of uncertainty of the market environment does not solve this problem. A conceptual model of the ACS activity is proposed, which is used in this research to form and manage the critical values of parameters expressed through the balance sheet sections and the Lebesgue measure. It is proved that the theoretical value of the developed approach to determining the critical parameters of the business systems of the ACS on the basis of the Lebesgue measure consists in a comprehensively taking into account the interaction of costs of all types of economic activities to be accounted for in business planning of industrial production. The calculation data and graphs are presented, which allow to practically determine the critical indicators of the parameters of the business systems of the ACS and to flexibly manage the parameters of the current consolidated balance sheet to prevent the critical status of the business system of the ACS.

It is determined that use of the economic-mathematical optimization models should be feasible in substantiating prices and volumes of products in order to maximize the profit of enterprise based on the analytical capabilities of the economic model of break-even production. The task of optimizing the determination of the level of prices and volumes of products in a multi-topic production is formulated in both substantial and mathematical form, allowing to receive the maximum profit at the limits in terms of the size of production capacity. As an optimization parameter, it is proposed to use the value of margin income by types of products for which the optimal values of price and volume are defined. A scheme is developed to solve the formulated task and recommendations are given for the implementation of its blocks. As the baseline data are used the price dependencies and variable costs per production unit on the volume of output, on the basis of which margin income per production unit along with the the corresponding production output are calculated. A step-by-step optimization method has been chosen to solve the task. Every step represents another type of production. Upon it is formed an array of value of margin income for the volume of products in the physical measurement with the selected interval, from which the maximum value is determined. The terms of the restriction are then checked. As result, the maximum margin income and the corresponding prices and production volume are determined for each product. Further, by subtracting from the maximum sum of the total fixed costs, the amount of profit is calculated, which is the maximum for the conditions of these optimization task. The proposed recommendations are checked using the example of conditional data for three types of products. Article is written in Ukrainian

Mathematical Modeling of the Equilibrium Price Formation Taking into Account the Logistic Factor (p. 125 - 130)
The article is aimed at economic and mathematical modeling of influence of logistic mechanisms on the processes of equilibrium price formation. An approach to consideration of logistics factor in mathematical models of the equilibrium price formation is proposed, according to which virtual logistician is introduced into the model, which, unlike the auctionist in the classical economic and mathematical models of this type, acting on one particular rule, is able to choose on a rational way the rule of price adjustment for balancing the market at some given aggregate. In the system «producer – consumer – market», rules of equilibrium price formation can be related to each of the three specified elements. As a criterion of choice of rules are considered the minimum time of achieving the equilibrium price (some approximation) or the maximum sales volumes with the value or natural calculation. Analysis of the constructed mathematical models (proposed modifications of the equilibrium price model of Evans) allows to demonstrate the possibilities of logistic mechanisms that provide improvement of the most important parameters of market functioning. The probable directions of development of the presented results may be related to research of economic and mathematical problems of construction and type assignment of the possible rules of action of the logistician in the market in order to bring it to equilibrium state in the most rational way.

Researching the Factors of Influence on the Management of Educational Services in Ukraine (p. 161 - 170)
The article identifies and researches factors of influence on the management of educational services in Ukraine. It turned out that education in all the world countries has always been the driving force of society development, since only the presence of qualified personnel in all sectors of the economy provided an opportunity for effective activity and implementation of scientific-technical progress into production. It is specified that today the principles and methods of management of educational services in Ukraine have undergone dramatic changes, as the market requirements dictate new rules, which are conditioned by certain requirements for the educational process and the creation of such an educational environment that would meet European standards. In order to improve the management of educational services in Ukraine, the factors that the most influence the quality and demand of educational services in educational institutions are singled out. To establish a statistical dependence between random values, a correlation analysis was applied, allowing to determine the presence and magnitude of the dependency between several random values. The linear correlation link between a pair of random values measured at the interval scale is determined according to the Pearson correlation coefficient. Factors of influence on the management of educational services in Ukraine are chosen, which have absolute and relative values. The absolute values of the factors that have an impact on the quality of educational services in institutes, academies, universities of Ukraine are computed; the absolute values of the factors that have an impact on the quality of educational services in colleges, technical schools, schools of Ukraine; the values of factors that have an impact on the quality of educational services in higher education institutions of Ukraine are computed as well. It is concluded that the analysis of absolute values of factors of influence on the management of educational services in Ukraine has a high link. This is explained due to the fact that regions of Ukraine, which have a certain rating as to the provision of educational services, also have competitive advantages in terms of the number and quality of scientific-pedagogical workers and, as a result, a significant number of applicants for education. For the relative factors of influence on the management of educational services, there is no high link between relative indicators. Article is written in Ukrainian

Applying the Data Modeling Tools for the Gender Inequality Analysis in the IT-industry in Ukraine and Worldwide (p. 165 - 171)
Nowadays, the information-technology industry is one of the most masculine and asymmetrical in the world labor market. The fact of having male workers in more prestigious and highly paid positions is proved, while female workers are more represented in low-profitable sectors of the economy (healthcare, education, social services, etc.). The article is aimed at researching the status of gender inequality in the IT sphere in the labor market of both Ukraine and the world by means of modeling tools. The publication analyzes the current status of gender segregation of labor in the sphere of information technology worldwide and in Ukraine. The relevance of the research on the process of functioning of companies engaged in foreign economic activity is substantiated. Using statistics of the most technological companies in the world (Amazon, Microsoft, etc.) it is proved that the average share of women in the companies comprises 30-40% of all employees. Gender inequality, as it has been proven, harms the business of companies around the world. Replacing female employees who resigned from a job because of the inability to build a career increases business costs and slows down the activities of individual projects and/or companies in general. At present, most large international companies deliberately perceive the need to achieve gender equilibrium among their employees. Despite numerous measures that have a positive impact on the involvement of women in the IT market, there are factors in the global labor market that increase gender discrimination, as emphasized in the article. Economic-mathematical models of the process are built up using multiple regression with panel data. With the help of the appropriate criteria, the quality of the built up models has been proven. Economic interpretation of the results is provided. Prospects for further research in this direction are described. Article is written in Ukrainian

Estimating the Payback Period of an Investment Project in the Framework of a Fuzzy Set Statement of the Problem (p. 173 - 179)
The article is concerned with the problem of fuzzy-set-based evaluation of the payback period of real investment projects. Initially, the most general features of the approach, which is implemented to find a discounted payback period for an investment project in the form of a fuzzy value (number), were highlighted. After that, the approach to modeling the latter with the help of payback function was thoroughly considered. It is identified that, along with the obvious advantages of this instrument, its significant disadvantage, in terms of the original version, is that the scope of the payback function is limited to the investment projects, for which, after a minimum period of time, when there may be a payback scenario among other scenarios, the sequence of fuzzy estimates of the indicator of accumulated discounted cash flow is non-decreasing. The publication formulates a generalized version of the payback function of the investment project, free from this disadvantage. Using conditional data, the proposed modification was tested, which demonstrated its viability. Particular attention is paid to the formulation and approbation of the indicators that can be obtained on the basis of the payback function and which reflect certain, significant in terms of analytical needs aspects of the payback of the investment project in time.

Determining the Probability of Bankruptcy of Production Enterprise (p. 186 - 191)
The main aim of this publication is to research and substantiate the possibilities of using traditional methods of analyzing the financial position of entrepreneurial entities in conjunction with the methodology for determining the probability of bankruptcy of enterprise. The country’s economy is characterized by a financial and economic crisis, which caused a powerful wave of bankruptcies, which intensified scientific and applied research directed towards introduction of an effective system of early warning and response to the threat of critical bankruptcy at domestic enterprises. Both foreign and domestic methods of analysis of the probability of bankruptcy of enterprise are researched, their advantages, disadvantages and possibility of application are defined. The reasons for the bankruptcy of domestic economic entities are highlighted and a set of actions within the framework of the anti-crisis financial management to prevent bankruptcy is proposed. Both the Western and domestic models of bankruptcy probability assessment are considered. As an example of the Western model, the Altman’s five-factor model and the Springate model were chosen, as an example of the domestic model – the one by O. Tereshchenko and A. V. Matviychuk. The purpose of use of the models analyzed in the article is to determine the financial stability of enterprise in order to assess its financial potential. Also the benefits of using these models among other existing ones along with the factors that may impact them are highlighted. For the example of application of these models data of PJSC «Kyiv Vitamin Plant» was used. Stabilization of finances of enterprises was and will be a priority direction of financial stabilization of both the individual enterprise and the economic system. A practical solution to this problem is possible only by replacing the existing financial policy with flexible forms of it and ensuring the stability of the enterprise operation. Depending on the probability of bankruptcy, regulatory measures such as entering the voluntary administration or the transition to anti-crisis management be implemented.

Evaluating the Efficiency of Commercial Banks Using the DEA Method (p. 192 - 197)
The article examines the application of the DEA (Data Envelopment Analysis) method in assessing the efficiency of commercial banks. This approach does not require knowledge of the efficiency function form. Using empirical input values and results of the financial and banking institutions, we are looking for a weight ratio to maximize efficiency. The article is aimed at evaluating the quality of management of commercial banks using the DEA model. As the methodology was chosen the DEA-modeling, because this method eliminates the problem of heteroscedacticity, which occurs during the parametric modeling. In the methodology of the analysis of the environment of the banks’ operation, commercial bank is considered as an economic unit with specific costs, which, as a result of the implemented activities, are used to generate concrete results. The article develops the principle of extracting information from observations. Thus, compared to the parametric approach dealing with the data averaging within a single regression model, the DEA method allows building up a Pareto-optimal-limit of all solutions, taking into account each individual observation. When analyzing the activities of commercial banks, their assets and the number of employees were selected for research taking into account resources, respectively. On the other hand, the result was the achieved value of deposits, the cost of loans, the number of clients of the bank and the provision of this bank, determined by the solvency coefficient. It is determined that the greatest impact on the results of the research have the size of the received deposits and loans of commercial banks. Measuring the efficiency in this article lies in finding a minimum value of the efficiency ratio, which reduces inputs, but so that the level of the source data remains at the same position. Upon the basis of the research, it can be stated that human resources and assets mostly influence the size of deposits and loans and have a high level of efficiency. Therefore, competition between financial institutions for clients is intensifying. Article is written in Ukrainian

Development of a Model of Strategic Controlling for Confectionery Enterprises in the Conditions of Anti-Crisis Management (p. 271 - 279)
Ensuring the harmonious economic development of enterprises in leading sectors of the economy requires constant monitoring of the objectives and the availability of a plan to combat potential crises at various levels of management. The experience of implementing the tools of operational and strategic controlling in enterprises shows a significant increase in the level of competitiveness, improving the forecasting of rapid response to such a problem. The purpose of this article is development of an improved model of analysis and forecasting of the probability of crisis and bankruptcy for the enterprises in confectionery industry. The article analyzes the confectionery industry of Ukraine. The main problems and prospects of the industry development are identified. Strategic controlling as a tool of crisis management is considered. The model of the analysis and forecasting of probability of a crisis situation and bankruptcy at the enterprises of the industry is developed. In contrast to the existing ones, the proposed model for confectionery companies considers the importance of financial indicators in the dynamics, as well as takes into account the external factors of the country (political and social environment). The main advantage is that it is designed for domestic enterprises and allows to take into account their quality indicators and the specifics of activities, as well as the macroeconomic situation in the country. The universality of the indicator of financial condition assessment is that it can be applied both to joint-stock companies (participants of stock exchanges, foreign economic activity) and to enterprises that do not operate in the stock market and are not engaged in foreign economic activity (the first part of the formula). A confectionery company can successfully fight competition only if effective controlling is applied. The calculation of indicators according to the proposed model in a few years will help to predict the threat of a crisis in order to timely implement the necessary management measures to address current problems and avoid them in the future. Preventive anti-crisis management with the use of operational and strategic controlling tools will ensure the implementation of goals and increase the efficiency of the company's management.

The Empirical Evaluation of Both the Internal and the International Fisher Effects for the Economy of Ukraine (p. 279 - 285)
The article works out the essence of theoretical concepts of both the internal and the international effects named after I. Fisher. A review of professional publications gave reason to conclude that in the countries with higher levels of marketing of the economy, the strength of these effects is higher, which indicates a higher level of integration of their national financial markets into the global financial market. Based on the results of an econometric analysis, the authors have concluded about the relative weakness of the internal Fisher Effect and, consequently, on the need to use multifactor analysis in the study of the dynamics of the real interest rate in Ukraine. The empirical evaluation of the dependencies of monetary variables in the model describing the international Fisher Effect gave reason to conclude about the relative weakness of this effect, in particular for the currency pair of «dollar – hryvnia», and therefore, the differential of national interest rates is not sufficient basis for forecasting the dynamics of the foreign exchange rate. The article uses a number of statistical criteria and tests to examine the used econometric model, which gave grounds to conclude about its adequacy and statistical significance of variables. The authors elaborated the factors that have a restrictive impact on the international movement of capital and therefore can cause differences in the real interest rates, especially in emerging markets, namely: asymmetry of market information, psychological barriers, national legislative restrictions that quota the international capital flows, high transactional costs, peculiarities of the tax system, currency risks, political risks, etc. The thesis that the presence of weak Fisher Effects for the Ukrainian economy is one of the reasons for the low effectiveness of the interest channel of the transfer mechanism of monetary policy in Ukraine is substantiated.

Features of the Sale of Export Products of Agricultural Enterprises in the Conditions of Risks (p. 285 - 292)
The article is aimed at modeling the sale of exported crop production and animal husbandry of agricultural enterprises in the conditions of risks. It is identified that agricultural activities are accompanied by a number of threats of socio-economic, financial, market, infrastructure, systemic, environmental and institutional nature; some risks have been exacerbated in recent years due to climate change and food price instability. It is proved that small agrarian enterprises are especially vulnerable to the problems of ensuring their means of livelihood, may experience difficulties in assessing and managing risks, and do not receive an appropriate effect from investment opportunities that can improve business and strengthen their sustainability. Several risks that accompany the agricultural sector of Ukraine and often become real threats to its socio-economic development are allocated as such that are the least taken into account by agricultural enterprises of various organizational forms and sizes. They are gathered to six groups (market; reduction in labor potential; systemic; loss of trust; political; legal). The method of fuzzy sets (fuzzy logic) is applied, based on the Matlab package and the Fuzzy Logic Toolbox module, within which a fuzzy logical classification and inference system is created. The fuzzy format of the calculation results is ensured by the two-step sequence of the formation of sets (phazification and dephazification). According to the results of modeling the optimal export volumes under the influence of external and internal risks, it is proved that ensuring large volumes of plant exports is accompanied by medium and high levels of market risks, medium and high risks of reducing labor potential and medium and high levels of market risks; ensuring large volumes of exports of animal products is accompanied by low and medium levels of market risks, medium and high levels of risk of reducing labor potential, high levels of market risks and high levels of legal risks. The proposed model is favorable for agricultural enterprises in the process of their economic activity in order to identify the strength of either positive or negative impact of risks and other hidden connections to predict and optimize their activities, which will allow to more clearly establish the strategic priorities of their activities and use resources more rationally.

The Information and Analytical Model of the Decision-Making Process for the Development of Health Insurance Programs (p. 119 - 133)
The article is aimed at studying and automating the stages of decision-making process for the development and implementation of health insurance products using the economic, mathematical, and simulation modeling. When analyzing the scientific works of scholars on the development of health insurance in Ukraine, the main stages of the decision-making process are allocated, the major of them are: the market need for an insurance product in the external environment; clear definition of the company’s tactical and strategic goals; examining the properties and characteristics of the insurance product; risk assessment and profitability of the insurance product. In the course of the study, the modeling of risk assessment, profitability of health insurance programs and analysis of the obtained results were carried out in detail. It is substantiated that a comprehensive analysis of the risk and profitability of health insurance programs will allow to form the necessary insurance reserves, to ensure the competitive position of an insurance company and to fulfill the targeted goals. If statistical information is available, any health insurance programs, including the COVID-19 insurance programs that require an assessment of pandemic risk, which requires special attention from both society and insurance, can be analyzed. It should be noted that modeling is a key element for assessing and managing pandemic risk. Prospects for further research in this direction are the expansion of the base of economic, mathematical and analytical models for assessing the risk of insurance portfolio and the inclusion in the simulation model of a wider range of factors of both the external and the internal environment.

The Impact of Monetary Policy on the Financial Stability of the Banking System: Setting a Modeling Problem (p. 81 - 88)
The publication is concerned with highlighting the results of the carried out analysis of the existing practice of developing macroeconomic models directed towards determining the main parameters of monetary policy of central banks, as well as assessing their impact on the indicators of financial stability of the banking system. Given the low efficiency of the traditional approaches to the formation of the monetary rule both in countries with developed market economies and in countries with small open economies (in particular, Taylor rule), possible ways to solve this problem are proposed taking into account the existing experience in shaping monetary policy parameters in the context of inflation targeting, which is already available at the NBU. The strengths and weaknesses of the main approaches to the modeling of the monetary transmission mechanism, as well as the forecasting of its impact on the financial stability of the banking system, which are used in the formation of basic and auxiliary models of the central bank, are analyzed. Particular attention is paid to structural econometric models, vector autoregression models and dynamic stochastic models of general equilibrium. As a result, a possible variant for developing an approach to macroeconomic modeling is proposed, in the framework of which assessment and analysis of the impact of monetary policy on the indicators of financial stability of the banking system is envisaged. The practical implementation of this approach makes it possible to develop models for assessing and analyzing the efficiency of the current monetary policy, projecting macroeconomic development scenarios in the short and medium term, which will both directly and indirectly determine the indicators of financial stability of the banking system.

Features of Modeling the Probability of Bankruptcy Using Discriminant Models with Application in Economic Forensics (p. 88 - 93)
The article is aimed at studying the methodologies of forecasting bankruptcy, their application in forensic economic expertise, which will allow to make managerial decisions substantiated from the point of view of financial security of an enterprise and create opportunities for stable functioning and development of the enterprise. All enterprises are affected by negative factors and may find themselves in a crisis situation. That is why the management of enterprise should apply all existing measures to prevent bankruptcy and overcome crisis situations. Any crisis situation can be corrected if you respond to crises in time and form a balanced and adequate management system. Therefore, the use of bankruptcy forecasting methodologies will allow the management of enterprise to identify in advance negative trends in its development. The article analyzed the existing discriminant models for determining the probability of bankruptcy with their application in forensic economic expertise. In modern practice of the financial-economic activities of foreign firms, to assess the probability of bankruptcy, the discriminant models of Altman, Beaver, Taffler, Tishaw and some others received the widest application. It is defined that for a more justified forecast, it is advisable to use several methods at the same time to predict the probability of insolvency (bankruptcy) of enterprise. It is proposed to use a set of models to determine the probability of bankruptcy of enterprise in solving issues of economic forensic expertise, which will significantly increase the degree of probability of the results obtained. The proposed measures can be used not only to diagnose the likelihood of bankruptcy, but also to develop anti-crisis measures. Article is written in Ukrainian

The article proposes a model for evaluating the activities of retail enterprise, which is based on five stages and allows determining ways to increase the efficiency of functioning, which will improve the adaptive properties of the economic object. The analysis of types of KPI is carried out, process and functional approaches are identified as the main ones for the direct development of key performance indicators, as well as the characteristics of the evaluation of effective marketing at enterprises, including those that function in the sphere of retail trade, are determined. The authors considered how modeling and forecasting of key financial indicators of an enterprise contribute to the creation of strategies for its development. The article notes that for the initial evaluation of a retail enterprise focused on long-term success, it is mandatory to conduct an audit aimed at assessing the efficiency of the economic object and defining how quickly the enterprise adapts to dynamic environmental conditions. The carried out analysis allowed to identify the key factors that contribute to an improvement of the enterprise’s operation. Also, on the example of the Isikawa diagram, the ratio of KPI, strategies and understanding of business processes was considered in order to set, control and analyze the achievement of goals.

Applied Aspects of Industrial Production Research in Ukraine (p. 73 - 81)
Industry is one of the important sectors of the economy of any country in the world. At the same time, statistics show that the industrial complexes of many countries are developing unevenly, with periodic changes in the structure and volume of production under the influence of many internal and external factors. Ukraine's industrial complex is also undergoing spatial and structural distortions, but these trends do not always correspond to those formed in the world's leading countries in the direction and pace of change, although today the industrial complex of Ukraine is the most important structural part of Ukraine's economy, a third of fixed assets and more than 30% of the employed population. As one of the largest spheres of social production in the country, industrial production determines the level of its socio-economic development, the specialization of the economy and the extent of participation in the territorial division of labor. Properly chosen strategy for the development of industrial production, the appropriate volume and structure of production, a reasonable volume of sales allows all participants in production to achieve their financial goals. This is due to the importance of studying the activities of industrial enterprises. The article constructs nonlinear models of multiple regression, which describe the main trends in industrial production, the effect of external and internal factors on the economic performance of industry in general and industrial enterprises in the western region of Ukraine. It is established that innovative transformations in industrial production have led to the renewal of fixed assets and have had a positive effect on the dynamics of economic results. At the same time, this process was accompanied by a reduction in the number of people employed in industry. It is revealed that the influential factors of the external environment include economic conditions of management, and among the factors of the internal environment – the management of innovation and innovation activity of economic entities. It is recommended to expand the set of tools at the expense of distribution-lag, autoregressive, simulative and other econometric models to describe the relationship between the economic performance of enterprises and factor characteristics.

Management of Development of Projects of Product IT Companies on Simulation Platforms (p. 108 - 123)
The article is aimed at disclosing the possibilities of using the simulation modeling apparatus in the management of the development of projects of product IT companies. Based on the analysis of a number of literary sources, an overview of research in the field of IT project management is carried out and the existing status of application of the simulation instrumentarium in the solution of applied tasks is described. The compliance of simulation technologies with the special requirements of the tasks inherent in the processes of software products development is substantiated. According to the life cycle of software creation, a brief characterization of the typical stages of project promotion is provided. A simulation model is proposed that reproduces the dynamics of the deployment of product projects of IT companies. The model is built using a hybrid approach – a combination of discrete-event and agent-based methodologies – on the software platform for multi-platform simulation AnyLogic. The discrete-event approach provides a high degree of detail of the processes being modeled. The agent-based approach allows to define the project as a dynamic unit with specific properties, which makes it possible to take into account the peculiarities of products ordered by consumers – clients of an IT firm. The model’s work is demonstrated by the results of standard and optimization simulation experiments implemented on conditional data of an average product IT company. These situations prove the possibility of using the model as a platform for making managerial decisions by the head of the product project development team. The model is presented as a simulator with the modular, open architecture and parametric adjustment for specific conditions of experiments. It may be recommended for product IT companies to practice management of the projects of software development. Article is written in Ukrainian

Modeling the Impact of Intensification of Migration Processes on the Socio-Economic Stability in Ukraine (p. 123 - 133)
The article is aimed at elaborating an adequate mathematical instrumentarium for the formation of migration flows to assess their impact on the socio-economic stability together with unshadowing the Ukrainian economy, as well as to identify efficient measures of the State-based policy directed towards regulating these flows to prevent risks of socio-economic destabilization. The article carries out an empirical analysis of the peculiarities of the development of migration processes in Ukraine and their impact on the socio-economic state in both the medium and the long term perspective. A system of complementary dynamic macromodels of the Ukrainian economy is developed, which includes a vector autoregression model and a separate complex of simulated submodels of systemic dynamics aimed at researching migration processes and their impact on the indicators of socio-economic stability. At this, the developed models of system dynamics can be combined into a single original simulation macromodel of Ukraine, and be used independently subject to the research goals. This allows to adequately describe complex nonlinear processes, systemically identify and examine the mechanisms of supply and demand formation in the labor market, taking into account the shadow component and assess their impact on the formation of the size of migration flows, as well as to research the consequences of increasing the intensity of migration processes on the socio-economic stability in Ukraine. The implementation of the developed complex of dynamic models has allowed, in particular, to calculate the annual value of the net migration flow in Ukraine through the aging chain of the population; to empirically confirm that migration flows in Ukraine are underestimated; to detect the dynamic structure of the net migration balance and a noticeable fading of the amplitude of migration processes over time, which indicates the presence of a balancing structure for the formation of migration flows.

Correlation of the Main Indicators of Economic Development of Regions (p. 90 - 99)
The stability of dynamics of economic phenomena in the regional economy is associated with the general level of economic development of the country. The most important studies are based on the results of the analyses of the economy of developed countries. The article formulates conclusions on the relationship between economic differentiation and economic stability, as well as between instability and economic growth. Research of regional development should be based on a comprehensive and comprehensive definition of the management object – the region. Therefore, the authors emphasize that studying the economic development of regions is of particular relevance in modern economic conditions, when decentralization processes are taking place in Ukraine. To study the status of Ukraine’s economy at the regional level, it is proposed to implement a methodology based on the methods of synthesis and gradual specifying. To formalize the results of the practical application of the proposed research methodology, generally accepted indicators of the dynamics of certain directions of the country’s economy development were used. The use of dynamics indicators allowed to identify, on the one hand, long-term tendencies and trends of individual elements, and on the other hand, short-term changes in the processes of economic growth and development. The use of the built regression model can be used in forecasting GDP values per capita within the framework of the regional economic development policy. The authors demonstrate that an analysis of the similarity of dynamics of indicators of the economy of regions (correlation) and the dynamics of results of their economic activity, calculated according to the GRP indicator per capita, should be applied when substantiating the provisions of the regional economic development policy. It is recommended to build the policy of economic development of the regions taking into account the experience of the above-mentioned regions in the sphere of economic development. An interdependence is identified, which indicates an increase in the share of the resource economy and a decrease in the share of the science-intensity economy, the development of which contributes to the welfare of the country’s population.

Displaying the R-Assessment of the Enterprise’s Level of Financial Condition on the Verbal-Numerical Scale (p. 100 - 107)
The publication considers the features of construction of the so-called «Harrington’s scale», which is widely used for economic research in Ukraine. It is demonstrated that the scale proposed by Harrington cannot be applied for arbitrary economic indicators. For the purposes of this study, an analysis of the applicability of the Harrington’s function for specific economic studies is carried out and it is shown that the «Harrington’s scale» cannot be applied to economic indicators, the increase in the value of which indicates an increase in the «quality» of the functioning of enterprise, for example, such as the «economic potential of the enterprise» or the enterprise’s «level of financial condition» (the latter requires the construction of a verbal scale according to the new probabilistic principle which is considered in this article). The indicator of «level of financial condition» is chosen because, as a rule, the current monitoring of the financial condition of enterprise is to be carried out automatically, by means of the appropriate tools, based on the multi-criteria methods for assessing the level of financial condition. One of these methods is the method of R-assessment of the financial condition of enterprise according to the Sayfullin – Kadykov model, which takes into account five criteria and puts them in line with the R-assessment. The article considers the main provisions of Harrington’s work in order to provide the possibility of correct use of the Harrington’s desirability function for the qualitative assessment of economic indicators, including complex and integral indicators that are used to monitor the financial condition of enterprise. The article proposes another function in place of desirability function, namely the function of distribution of the indicator under research, whether theoretical or empirical. In addition, the limit values that separate the different values of the linguistic variable at the base interval are proposed to be determined according to the statistics of the group of companies to which the enterprise under research belongs, or can be included according to the criterion of homogeneity with any enterprise of the researched group. An example of constructing the correct qualitative scale for a normally distributed variable of «level of financial condition of the enterprise» at the probabilistic level is provided. Attention is drawn to the fact that the boundary values of the qualitative scale significantly depend on the law of distribution of the variable under research. Article is written in Ukrainian

The Information-Analytical Provision of Analyzing the Export-Import Potential of Enterprise (p. 107 - 113)
The article contains theoretical and practical recommendations on analyzing the export-import potential of industrial enterprises in modern conditions; the content of the information-analytical provision for analysis of such a potential is considered. The expediency of organizing the technology of analysis of export-import potential of the enterprise (EIPE) is substantiated according to the following logic of stages: 1) description of this potential on the grounds of signs and formation of a system of indicators; 2) establishing tendencies in changing the values of indicators based on the analysis of their dynamics; 2) comparison of the achieved levels of values with planned or normative (reference), accompanied by the search and detection of reserves and diagnosis of critical situations; 3) determination of the external environmental factors influence; 4) determination of levels of development of structural components of potential on the basis of integral indicators; 5) determination of causal relationships of elemental composition of the potential; 6) determination of the internal environmental factors influence; 7) analysis of dynamics of structural changes in the export-import potential; 8) determination and analysis of reserves for the efficiency of the use of the EIPE; 9) forecasting the values of the EIPE indicators for a better understanding of the changes taking place. In the information provision of analyzing the EIPE it is recommended to include partial and integral indicators that form a hierarchical system of indicators to describe this potential; criteria to determine the degree of achievement of the goal of functioning and development; references of the indicators that allow comparing and carrying out an analysis.

Optimizing the Intellectual Property Management in Accordance with a Process-Functional Approach (p. 41 - 51)
The article is aimed at developing a way to optimize the management of intellectual property (IP) objects by a process-functional approach based on the use of neural networks in combination with planning networks in conditions of uncertainty. When analyzing the works of various scholars, conceptual approaches to the formation of IP management according to both the process and the functional approaches to management were considered. The use of artificial neural networks in intellectual property management at industrial enterprises in combination with network planning in conditions of uncertainty is systematized. Neural networks consist of different architectures, but to manage intellectual property it is advisable to use either Self-Organizing Maps (SOM) by Kohonen, or Generative Pre-trained Transformer 3 (GPT-3), or Rumelhart Multilayer Perceptron, or an combination of the above. It is proved that the proposed scientific approach (instrumentarium) in the form of neural networks and network planning allows reducing the time for implementation of works related to the management of intellectual property at industrial enterprises on the grounds of a process-functional approach. Based on the carried out study, the computation of spent time was carried out, which confirmed the efficiency of the implementation of neural networks in combination with network schedule for the management of intellectual property in industrial enterprises. Prospects for further research in this direction are the development and construction of a universal instrument using neural networks and network schedule. Further development of intellectual property management will increase production efficiency and profitability of enterprises. Article is written in Ukrainian

Measurement of Economic Risk for a Non-Probabilistic Problem Formulation (p. 52 - 58)
The subject of the article is the methodical apparatus for quantitative assessment of the degree of economic risk for the situation of decision-making, under load of the nonstochastic (nonprobabilistic) uncertainty. The research implemented the task of further development of fuzzy-multiple risk measurement instrumentarium for the case of simultaneous nonstochastic uncertainty of assessments of the criterial economic indicator (criterion) and its norm. In accordance with the set goal and methodical approach to the interpretation of fuzzy assessments on the basis of an analogy between random and fuzzy values in the work a number of practically significant situations determined by the nature of the nonstochastic assessments of the criterial economic indicator and its norm were consistently considered, for each of these mathematical ratios were found to calculate the degree of risk. The proposed calculation formulas were tested on conventional examples. The results of the tests showed the capability of the developed computing apparatus. The research also focuses on the situation of risk measurement, when the assessment of the criterial economic indicator is modeled as a random variable, while its normative level is described by an assessment, either interval or fuzzy. As a perspective direction of further scientific research on the issues raised in the article, the formation of some generalized methodology for quantitative assessment of the degree of economic risk, which would allow to measure the risk for various situations of information uncertainty from a single theoretical position, is defined.

Modeling the Volumes of a Special Stabilization Reserve Fund (Example of the Hotel «Zhovtnevyi») (p. 58 - 64)
The article specifies the use of an economic-mathematical instrumentarium to ensure a sufficient level of financing of operating periods of enterprises. This instrumentarium is represented by a special stabilization reserve fund of enterprises and a system of models: a model of the formation of the fund, its adaptive mathematical model and an algorithmic model of fund management, implemented in the form of a relevant computer program for assessing the volumes of additional financing and recovery and the volumes of increase of the fund. To build a conceptual model of the process of ensuring financing of operating periods of enterprises, system analysis methods along with predictive proportional method were used, which is due to the use of data of balance sheet statements of enterprises. The economic essence of the process is a special stabilization reserve fund of the enterprise, which, according to the legislation of Ukraine, is formed at the expense of its own investments and is created at the conscious desire of the owners, and this is fixed in the statutory documents of enterprises. The mathematical essence of the process is a system that contains a mathematical and an algorithmic models of the fund. In order to assess the volumes of the special stabilization reserve fund of the enterprise, an analytical approach to the value of money over time was applied to the analysis of the cost function. Quantitative assessment of the upper limit of the increase in the special stabilization reserve fund of enterprises is based on the assumption that the forecast amount of money flow of costs for each subsequent operating period will reflect the financial limit of the development of the process in the next period in a crisis-free situation. The mathematical model of the fund easily adapts to the working conditions of each particular enterprise. It can be used even in the downturn production process as a stabilizing investment. The proposed instrumentarium should be used both for production enterprises and for enterprises providing services, for example, hospitality institutions. The publication is based on statistics of the hotel «Zhovtnevyi» (Ukraine). Article is written in Ukrainian

The Perspective Directions of Modeling the Processes of Estimation and Analysis of Investment Component of the Socio-Economic Development of Region (p. 116 - 121)
The publication is devoted to highlighting the results of the study of the existing practice of evaluating and analyzing the indicators that determine and characterize investment processes at the regional level. The carried out analysis of available methods of assessment of the investment climate of region showed that quite often in the process of research a number of factors are not taken into account, which, under other equal conditions, can become pivotal in the process of deciding whether to invest or abandon such an intention. It is proved that the size and efficiency of use of the investment climate of individual territorial systems and entire regions will depend both on the level of investment attractiveness and investment activity, as well as on investment potential and the level of investment security provided. In other words, precisely investment potential and investment security act as prerequisites and a basis for the formation and practical implementation of investment policy at both the national and the local levels. As a result of the carried out analysis of the extant approaches to solving the problem of evaluation and analysis of the main parameters and characteristics of investment activity at the regional level, the main shortcomings and weaknesses of the currently available developments are identified. This made possible to outline promising areas of analysis using the advantages and capabilities of economic and mathematical methods and models. A practical implementation of the perspective directions of analysis with the use of an appropriate economic and mathematical instrumentarium allows to form models for assessing and analyzing the investment component of the socio-economic development of region, as well as projecting scenarios for regional socio-ecological and economic development in the short and medium term.

The Measurement (Assessment) and Modeling of the Operational Risk of Bank (p. 144 - 153)
In modern conditions of implementing banking activity under the influence of rapid technologization, the worldwide globalization and transformation processes, there is a significant vulnerability to risks. The risks that banks are exposed to during their activities can be divided into those that are subject to quantitative measurement (assessment) and those that cannot be quantified. Among all banking risks, operational risk has the greatest unpredictability and destructive nature of influence on the bank, able of instantly jeopardizing as the bank’s activities so its functioning. Operational risk is one of the risks that are inherent in quantitative measurement (assessment). Measurement (assessment) of the bank’s operational risk is an element of management of such a risk. The impact of operational risk on banking activities is manifested in the amount of economic effect (losses). To assess the economic effect of the impact of operational risk on banks, a retrospective approach was used as part of the study described in the article. The study on assessment of losses from operational risk was carried out on the basis of analysis of statistical data on the operational risk events in both the worldwide and the domestic banking practice for the last 30 years: from 1991 to 2021. Since the norms for maintaining databases of internal and external events of operational risk by the banks of Ukraine are correspondingly applied as mandatory and additional instruments for measuring operational risk since 2018, the authors of the article carry out modeling and analysis of the aforementioned databases of operational risk events on the basis of statistical data on the operational risk events for 2018–2021. As a result of the study, the model of measurement (assessment) of economic effect (losses) of operational risk, taking into account its sources, is specified. The model approbation in practical banking activities will increase efficiency of the operational risk management. A prospect for further research on measurement (assessment) and modeling of operational risk can be the accumulation of data on operational risk events for more annual periods and the construction on their basis of the model of losses from the operational risk of bank.

Modeling and Optimization of the Self-Cost of Production of an Entrepreneurial Structure (p. 154 - 161)
The article is aimed at analyzing the production self-cost of dairy products as an indicator of the efficiency of the economic activity of the entrepreneurial structure. The analysis consists in: determining which indicators of the articles of calculation form the self-cost of production for a certain period of their description; modeling the degree of influence of the calculation elements on the indicator; search and selection of practical measures to optimize the production self-cost of products of the enterprise Kharkiv Dairy Plant LLC. In the course of analysis of the dairy market of Ukraine, important problems of the industry are highlighted and the following factors of influence on the self-cost of production are identified: shortage of dairy raw materials, increasing the share of imported goods, and industrialization of enterprises. The dynamics of changes in the structure of production self-cost and production volume of dairy enterprise products within 22 months is considered. It was found that the main impact on the production self-cost have raw materials and wages of employees. After solving the equation of multiple linear regression using matrices, an adequate economic and mathematical model is obtained with the level of influence of six articles of calculation on the production self-cost of 1 tons of the fermented milk drink with the «Laktomix» fruit filler. The articles of calculation, in turn, represent the sum of productions of specific norms of costs and prices for them. Practical measures to optimize and reduce the production self-cost of dairy products on the part of the enterprise and on the part of the State are considered. Some measures are already being implemented at the enterprise, the other still exist only in the plans. One of the effective measures to optimize the self-cost of production is the use of membrane technologies, innovative biotechnological solutions, recycling of reverse waste and expansion of sales areas, which leads to an increase in production and sales of products.

Researching the Impact of Financial Innovations on the Main Financial Indicators of Ukraine (p. 108 - 113)
The article researches the impact of financial innovation on the yield of government bonds based on the models of ARCH family, it is proved that the introduction of financial innovations affects government bonds. It is determined that the dynamics of volatility of many financial variables is subordinated to stable regularities. The traditional pricing model for capital assets and its dynamic modification indicate a proportional relationship between the expected over-delivery of the market portfolio and its conditional standard deviation. The ARCH model is a natural instrument for studying this problem in a dynamic context where the conditional dispersion changes over time. The results confirm the influence of the exogenous factor of diffusion of financial innovations on the yield of government bonds of market participants in all cases. So, for the government bond yield curves, there is a significant possibility of forecasting. This is a very important issue in terms of active bond trading and taking into account the risk management of the loan portfolio. The influence of information flows and messages to financial markets regarding the behavior of the rates of two main foreign currencies, namely: the Euro and the US dollar, is researched. It is determined that there is a significant influence with the introduction of financial innovation along with information of market participants on exchange rates, which is expressed by the diffusion coefficient during the period of time chosen by diffusion. It is proved that the diffusion coefficient has a significant impact on market participants in terms of average profitability and historical volatility, it is also researched that the introduction of financial innovations reduces the displacement of model coefficients and volatility. The methodology presented in this publication can be used to compare different classes of assets, indices, and financial innovations. Article is written in Ukrainian

Inventory Management Modeling in the Budget Process of an Industrial Enterprise (p. 152 - 158)
The article is aimed at studying and substantiating the role of stocks in the budget process of an industrial enterprise, as well as elaborating a dynamic economic and mathematical model of inventory management, which would take into account the stochastic nature of demand for products and maximize profits that directly depend on the volume of output and, accordingly, on the stocks of finished products and raw materials available in stock. Since stocks affect profits, which, in turn, reflect a positive financial result of the enterprise, the application of the elaborated model will be the key to more effective activities of the economic entity as a whole. In addition, the use of the elaborated model simplifies the process of developing the enterprise’s budgets. The article proposes a perspective method for solving the problem of inventory management of an industrial enterprise in the budget process, taking into account the stochastic nature of demand. The simulation model of order formation and dynamic model of inventory management are elaborated, which allows to determine for each individual period the optimal production volumes that contribute to maximizing the total profit of the enterprise. The connection of stocks and budget is determined and the role of stocks in the budget process is established, as well as the need for research in this area. The elaborated model was applied at an industrial enterprise, which confirmed its effectiveness. Calculations for two different strategies for the purchase of raw materials are made and the optimal volumes of monthly production are determined. The result obtained through the use of the described methods is analyzed. The elaborated model can be used in the planning and development of budgets at any enterprise engaged in production activities. The actual direction of further research is the development and automation of the budgets consolidation system. Article is written in Ukrainian

Determination of Intra-Variable Losses of Working Time of Equipment by the Method of Instantaneous Observations (p. 159 - 164)
The article considers the use of the method of instantaneous observations to determine the intra-variable losses of working time and operating time of equipment by the method of instantaneous observations. The application of the method of instantaneous observations is especially relevant in the conditions of mass production, especially in the conditions of automated and semi-automated production. Additional reserves for the use of variable working time and increased productivity have been revealed. A separate example considers the method of applying the method of instantaneous observations to determine intra-variable losses. Based on the obtained results, absolute and relative indicators were calculated according to the elements of variable time fund losses. When processing the results of sample observation, averages were calculated, which characterize the average number of downtimes or average time loss per machine in absolute terms. It was found that non-production losses were recorded in 245 cases, which was 14.85% of the variable fund of equipment operating time. Based on the analysis of these indicators, it was concluded about the uneven use of variable stock of operating time of machines. The amount of losses of the variable working time fund, calculated on the basis of the method of instant observations, was much larger compared to the method of photography of the working day. The use of the method of instant observation in the company requires significantly fewer workers than in the photography of working time. The use of this method allows to obtain sufficiently reliable results that can be used in operational production at an industrial enterprise. Article is written in Ukrainian

The Determinants of Efficiency in Terms of the Scale of Operations by Leasing Companies in Ukraine (p. 165 - 171)
The article contains a regression model for assessing the average value of the efficiency of the scale of operations by leasing companies in Ukraine, which is built on the basis of DEA analysis. To determine the factors that cause a statistically significant impact on performance indicators obtained on the basis of DEA analysis, the authors use the appropriate regression models for panel data. To assess the efficiency of the scale of Ukrainian leasing companies for the analyzed period, the input-oriented DEA model with variable VRS and sustainable CRS scale effects was used. A statistical sample of the performance indicators of 21 leasing companies in Ukraine was formed, which was obtained from their financial and accounting statements for 2019-2020. Due to the significant sensitivity of SE scale efficiency to input and output variables, it was proposed to use an average scale efficiency value based on eight different DEA models. It is noted that if the CCR model determines the success of the management of a leasing company in the transformation of input resources into the output ones, then the efficiency of scale evaluates the correctness of choosing the scale of the leasing company. The analysis showed that the efficiency of the scale of the lessor’s activities in most cases depends on determinants such as administrative costs, fixed assets, and net profit of such companies. The obtained results indicate that with the increase in the size of the leasing company, the efficiency of the scale of their active operations decreases, since with an increase in the size of fixed assets and the volume of administrative costs, the average efficiency of the scale of their activities decreases. It is shown that the greater the net profit, the closer leasing companies work to the optimal scale of activity for them, which is determined by the volume of long-term receivables of the lessor and the size of his assets.

Formation of Directions for Increasing the Investment Attractiveness of Enterprise on the Basis of Methods of Economic-Mathematical Modeling (p. 38 - 48)
The article is aimed at defining the general directions for increasing the investment attractiveness of a construction enterprise on the basis of the use of economic-mathematical methods that allow taking into account the real state of the enterprise along with the impact of the external environment, and forming the main trends for the short term. On the basis of factor analysis, the main factors of influence on the investment activity of the enterprise are determined. On the grounds of the defined factors, the main directions for increasing the level of investment attractiveness of the enterprise under study are formed. Applying the method of analysis of hierarchies, it is identified that the most appropriate from the point of view of experts is the direction of development of financial intermediation between the bank and its clients. At the same time, this method is the safest, because it does not pose a threat to the growth of the amount of borrowed funds, at the same time, the attractiveness as a potential object of investment increases due to more favorable conditions for the provision of funds from the bank. In addition, in cooperation with banks of the Kharkiv region, an increase in the investment attractiveness of the region is ensured. Investment activity of economic entities is constantly influenced by the changing factors of the external and internal environment, so its research, including by using the methods of economic-mathematical modeling, remains relevant and requires further research in this direction.

Analyzing the Prognostic Properties of Composite Uncertainty Indices in the Preventive Crisis Management Systems (p. 84 - 91)
The publication researches the prognostic properties of composite indicators obtained on the basis of the method of the main components and uncertainty indices, allowing to provide a qualitative assessment of the probability of a «shock». The base of signal indicators for assessing the efficiency of composite uncertainty indices as preventive indicators is substantiated; a composite uncertainty index based on the methods of reduction of signs, in particular, the method of the main components, is elaborated; the predictive properties of the composite uncertainty index are evaluated in comparison with the generally accepted system of signal indicators. The received results showed that the most common signal indicators for both the developed and the developing economies have low preventive power and actually reflect the beginning of the recession phase, that is, the moment of the onset of a crisis. Further on, the indicators under consideration do not always allow prognosing the duration of the crisis phase. It is demonstrated that the traditional system of signal indicators is advisable to supplement with uncertainty indices that allow to predict a crisis with a certain warning lag. An approach to building a composite uncertainty index based on such a method of reduction of signs as the method of the main components is proposed. A comparative assessment of the efficiency of the signal indicator systems based on the NSR indicator made it possible to conclude that the composite uncertainty index has a better preventive characteristic of crises development, which can be used in the preventive management systems for the purposes of the timely use of the instruments of financial stabilization and security provision.

Regarding One Cointegration Task of Trade Relations Between Ukraine, Azerbaijan and Georgia (p. 49 - 60)
In this article, the integration processes between Azerbaijan, Ukraine and Georgia are considered through the indicators of integratedness of Azerbaijan’s GDP and the trade turnover of this country with the other two. All the time series considered are non-stationary. Therefore, the construction of a model of correlation-regression analysis will lead to the obtainment of shifted estimates of the coefficients. So, there are problems of correct modeling of the corresponding time series, the components of which lead to a deviation from stationarity. The publication uses an econometric integration methodology for modeling the relationship between the non-stationary time series. The modeling correctly used econometric methods, all the necessary step-by-step statistical procedures to determine the order of integration of the non-stationary time series – to identify and evaluate the parameters of the model and to check its adequacy and accuracy of both the short-term and the long-term forecast values using the tools of Excel and the EViews 8 package. An analysis of empirical tests for their deviation from the trend was carried out. The speeds of elimination of the imbalance and the visible convergences of the corrective system from the equilibrium trajectory are determined. A dynamic model of the long-term equilibrium is built, allowing to qualitatively forecast the state of foreign trade integration of the three countries under consideration and analyze the openness of the Azerbaijani economy in the regional aspect. As a result of the constructed model, econometric substantiated recommendations have been developed that allow for a dynamic analysis of effective State regulation of export-import operations between these countries to balance mutual trade.

Assessing the Efficiency of Leasing Operations in the Case of an Annuity Scheme for Calculating Leasing Payments (p. 75 - 80)
The article proposes a method for assessing the efficiency of leasing operations in the case of an annuity scheme for calculating leasing payments, which is based on comparing leasing with loan that is close in terms of economic essence to the method of financing real investments. This approach is often used by leasing companies and other participants in the leasing market in the United States when assessing the efficiency of leasing agreements. In the development of mathematical instrumentarium, the authors took into account the peculiarities of taxation and the functioning of all parties to leasing contracts in Ukraine and the current legislative and other regulatory documents in this area. This approach to assessing the efficiency of a leasing agreement is based on the fact that two cash flows, payments on which occur at different points in time, will be considered equivalent if their current values (or accrued amounts) calculated at the same discount rates turn out to be equal. In determining the discounted value of cash flows under the leasing agreement, it was taken into account that leasing payments, in addition to the minimum rental payments, also include the cost of services payable to the lessor, taxes and unforeseen leasing payments. Thus, if the present value of the company’s cash flows during leasing is greater than the present value of the cash flows of the same enterprise taking a loan, then it can be stated that the purchase of equipment through credit borrowings will be more profitable for the enterprise. Conversely, if the present value of the company’s cash flows during leasing is less than the present value of the cash flows of the same enterprise taking a loan, then the cost of equipment obtained through leasing will be lower compared to the purchase through loaning, and therefore it is more expedient for the enterprise to stick with the leasing agreement.

The Complex System of Simulation Modeling of Assessment of the Efficiency of Financial Resource Management of an Industrial Enterprise at the Microeconomic Level (p. 27 - 33)
The purpose of the article is to examine the features of a systematic approach to the total aggregate of methods for assessing the efficiency of resource management of an industrial enterprise, which methods can be divided into threshold and non-threshold, parametric and non-parametric ones. The peculiarity of a systematic approach to the corporate security system is studied and the main stages of this approach are identified. It is specified that a systematic approach is such one in the presence of which managerial decisions aimed at a competitive direction of strategic development of corporate security be considered in the form of an interconnected and interdependent integral complex. The objectives of the corporate security strategy of an industrial enterprise are substantiated, which should be subordinated to the general strategy of economic development, and the implementation of the management of the strategy for the formation of general corporate security, carried out through decision-making. It is concluded that the mechanism of management of the corporate security system must be represented as an integral organizational-economic system, which is also an integral part in the overall structure of the mechanism of an industrial enterprise. The main tasks and components of the model of the strategy of general corporate security are identified. In addition, it is noted that mechanism should be understood as a sequence of measures that are caused by an aggregate of interdependent elements of economic, logistics, personnel, legal, resource, transactional, information, technological security, forming the state and content of processes in accordance with a certain corporate security strategy.

Applying the Gravity Models for the Analysis of Trade between Ukraine and the European Union (p. 140 - 145)
This article presents the application of gravitation models in bilateral trade in agricultural products such as wheat, corn and barley between Ukraine and the European Union. The power of influence of factors related to the process of globalization on the volume of trade flows of agricultural products between countries is shown. These determinants were considered as an alternative to the physical distance between countries in the equation of gravity proposed by Jan Tinbergen. Trade relations between the EU and Ukraine are of interest in influencing the functioning of the entire sector of the economy. The weight of these ties is especially important if we take into account such sensitive markets as, e. g., market of agricultural products. In this case, trade and its results are affected by complex agricultural policies, including diversified support instruments or rules applicable in the EU and in Ukraine. Disparities in the scale of financial support for individual markets and their impact on the level of domestic prices have led to a diversification of the impact on trade turnover. This phenomenon also explains the lack of mutual attractiveness of economies in terms of trade flows. In the traditional gravitation model, the value of trade between any two countries is proportional (all other things being equal) to the GDP gain of these countries and inversely proportional to the distance separating them. In today’s global economy, physical distance between countries is no longer such a significant brake on international trade, and thus the distance in the gravitation model can be understood as the degree of similarity between economies trading with each other.

The Model of Control and Risk Assessment of Foreign Economic Security of National Economies in the Conditions of Global Crises (p. 40 - 47)
The aim of the research work is to form a model of control and risk assessment of foreign economic security (FES) of national economies in the conditions of global crises. Its implementation will make it possible to take into account the likely future threats of FES in time and introduce effective mechanisms for their extinguishing or reduction in the present time to form an optimal trajectory for the development of foreign economic relations. The article substantiates that as the forecast values of FES indicators for the formation of a model of control and risk assessment of FES of national economies, it is advisable to include the following indicators: the level of openness of the economy; import export coverage ratio; growth rates of exports and imports; the share of imports in domestic consumption of the country; level of unemployment. As a method of forecasting the FES indicators, it is proposed to use a consensus forecast based on the principle of calculating the median values of indicators based on expert assessments by macroeconomic analysis and forecasting specialists. The practical implementation of the model of control and risk assessment of the FES of national economies was carried out on the example of the Ukrainian economy as one that is subject to the strong influence of crisis phenomena that cause a complex of threats to the FES. The projected level of FES risk for Ukraine according to a pessimistic and probable estimate is dangerously high, according to an optimistic one – high. This means the presence of a destabilizing negative impact of the crisis occurrences on the foreign economic activity of the national economy and a significant decrease in its functionality. To ensure the proper level of the FES of Ukraine in the context of crisis, it is necessary to: improve the regulatory framework by introducing a mandatory norm for calculating the FES index annually along with the forecast value of the risk level; introduction of mechanisms to increase Ukraine's role in the world trade system through the development of high-tech sectors of the economy, in particular through attracting international investment; search for new opportunities for foreign trade cooperation and development of the internal market.

Modeling of Price Changes for Standard Rooms in Polish Hotels (Krakow) (p. 93 - 98)
The tendencies in the development of the hotel industry in Europe and in Poland in particular are analyzed. Extensive and relevant statistical material was taken from booking sites as of November 2022. Most often, the analysis of economic tendencies in the development of the hotel industry is based on expert assessments or statistical data from travel agencies. The conducted analysis is based on mathematical modeling and the use of Microsoft Excel mathematical and statistical tools. The world market of hotel services is constantly changing, has a dynamic structure, develops in interaction with other markets of goods and services, is influenced by the market environment. Therefore, modern hotels have to adapt to a new type of tourists with rather high requirements for accommodation conditions. In Europe, there is a tendency to stay in 1* and 2* hotels. The study covers data from the Polish city of Krakow. These data represent the spatial series, on the basis of which regression mathematical models are built for evaluating the tendencies of changes in the level of prices for the corresponding hotel rooms. The series are spatial because the data are collected at a specific point in time, but from different objects located geographically at different points. The built models are not representative, but they provide an opportunity to assess the tendencies of price growth or decline and the possibility of entering into crisis economic occurrences. The work is devoted to the analysis of tendencies of changes in hotel room prices and the evaluation of these changes using the construction of regression economic-mathematical models of space and time series. The relevance and significance of the study lies in the analysis and assessment of price tendencies for standard hotel rooms in the popular segment of 1* and 2* hotels in Poland. This country is Ukraine’s closest neighbor, therefore the study of economic trends in the development of its hotel industry is relevant not only for tendencies in Europe, but also for the future of the hotel segment of our country. The conducted analysis showed the presence of a mathematically defined tendency towards a moderate increase in prices for «standard» hotel rooms. The price function for these hotel rooms is an increasing one, but it does not cross the growth limit of the corresponding exponential function built on the same spatial number series. But such a tendency should not lead to any crisis occurrences in the hotel sector of Poland. Article is written in Ukrainian

A Cost Forecasting Model for Innovation Activities in the Industrial Sector of Ukraine (p. 73 - 79)
The article considers the problem of increasing the reliability of estimation of the cost of innovation activity in the industrial sector of Ukraine. Using as primary data the information of the previous study, the dependence of the costs of innovation activity on a group of factors is analyzed, as a result of which it was decided to build several multi-factor regression models. In order to build this group of models, the least squares method was used. In the course of checking the obtained multivariate models, it was found that each model has internal parameters in which the value of p-values exceeds the limit value, which means that the obtained values of the internal parameters of the model are not significant. Therefore, all multivariate models constructed using the least squares method were eliminated from further research. At the next stage of the research, one-factor regression models were constructed using the least squares method, where the amount of mastered production of new types of products (technological processes) was used as a factor. After sorting out the non-essential models, the remaining ones were compared with respect to their quality characteristics. However, in all univariate models, it was found that the calculated values of the average approximation error exceeded 10%. Therefore, yet again, all models have been eliminated from further research. Due to the impossibility of obtaining a model using the least squares method in the simulation process, it was decided to use machine learning methods with a teacher. Among the methods of machine learning, it was decided to pay attention to the following methods: k-near neighbors, regression trees, and neural network method. Taking into account that these models are not adversely affected by the multi-collinearity between factors, both the data for the models were used raw data without additional transformations. According to the results of the research, it was found that among the models using machine learning methods, the best models were the binary regression decision tree (with a hyperparameter value of max_depth = 3) and the neural network model. When comparing these models, it was found that the model based on the decision tree has a smaller value of the average approximation error, which means that this model can be recommended for use in making management decisions on forecasting the costs of innovation activity of industrial enterprises in the future.

Selection of Econometric Instruments when Building a Scoring Model Based on Dummy Variables (p. 128 - 133)
The aim of the study is to select adequate econometric instruments for building a scoring model on a specific array of initial data, which contains the vast majority of fictitious variables. Despite a significant number of developments devoted to the construction of scoring models, a universal method allowing to obtain a highly efficient classifier for any data has not been identified. Therefore, the task of selection of the best method for building a scoring model remains relevant, depending on the characteristics of the available data. The most successful approach when selecting a model for solving the problem of binary classification is the use of several types of econometric models and the choice of the best of them according to the results of classification. In the presented study, the following types of models were applied: discriminant model, logit and probit regressions, and polynomial logistic regression. Training samples with different structure were used. Comparison of all obtained models allows us to conclude that polynomial logistic regression is preferable in this case. This model demonstrates high classification rates for all introduced object classes and has an important advantage compared to models that make a binary selection. The advantage of polynomial logistic regression is also the possibility of selecting in each case a convenient scale for dividing borrowers into more than two classes and determining the level of probability of reliability of the borrower acceptable for its own conditions, at which it should be assigned to one of the selected classes. Prospects for further research in this direction are the use of machine learning methods that will be able to use ensembles of the best of the considered models. In addition, the proposed models can be used in solving similar problems in other spheres of economic activity. Article is written in Ukrainian

Risk Modeling of Banking Activities (p. 138 - 148)
The article is devoted to the study of the issue of banks’ risk management. Risk management is a complex but necessary process to ensure the financial stability of banks. Research and assessment of banks’ risks helps banks understand and manage risks, make more informed decisions about granting loans, investing and other operations. Risk modeling is an important part of risk management in banks, so the article proposes improving the methodology for assessing the level of risks of banking activities, which, on the basis of forecasting methods and simulation modeling, allows to improve the validity and quality of managerial decisions in the field of management of financial activities of a bank. The task of risk assessment is a central element of the risk management system in banks. In order to improve the methodological base, the article proposes a conceptual scheme of modeling the risks of banking activity, which includes four blocks: development of currency risk assessment models; development of credit risk assessment models; stress testing of banking risks; making decisions to stabilize the financial condition of the bank in each of the proposed scenarios of modeling the risks of banks’ activity. In accordance with this, on the basis of the carried out study of the bank’s financial statements and methods of assessment and analysis of risks of banking activity, the following simulation models have been developed: a model for assessing the level of currency risk; a model for assessing credit risk and determining the amount of its reserve according to national and international standards; a complex risk assessment model. After building and examining the models, the methods of system dynamics were used, namely: simulation modeling, stress testing, and sensitivity analysis. Simulation modeling has become an effective tool for studying the risks of banking activities, as it made it possible to create virtual models of banking operations and test them on various risk scenarios. Stress testing allowed to study the impact of shock events on the financial stability of the bank. Sensitivity analysis was used to identify the most sensitive parameters of the model and to determine how changing these parameters affects the model results. Article is written in Ukrainian

A Study of the Efficiency of Functioning of the National Economy Using the Tools of the «Input – Output» Model (p. 111 - 117)
The aim of the article is to determine the indicators of efficiency of functioning of the national economy by the methods based on the economic-mathematical model of «input – output», and to conduct their comparative analysis. The publication allocates two main approaches to assessing and analyzing the efficiency of functioning of economic systems that use the above mentioned model. According to the first of them, the Frobenius number of the technological matrix of V. Leontiev’s model is considered as an indicator of efficiency (productivity, cost). Another approach uses the relevant elements of the matrices of the coefficients of direct and total material costs to build performance indicators. By demonstrating numerical examples, it is shown that performance indicators using Frobenius numbers can give incorrect results for some changes in the values of the elements of the technological matrix. This circumstance casts doubt on the possibility of using such indicators in the economic and mathematical analysis of macrosystems of production and distribution of products under the description of their functioning by V. Leontiev’s models. The carried out analysis of the dynamics of efficiency indicators, which are based on the elements of the main matrices of the «input – output» model, and the GDP growth rate indicator, calculated for the national economy in 2012–2020, shows that the processes of change in the size of the Ukrainian economy in this period are not directly related to the efficiency of its functioning and are determined mainly by simple scaling. Further research can be developed in the direction of using the economic and mathematical apparatus of the «input – output» models to form recommendations for improving the efficiency of the functioning of the relevant economic systems, as well as a more detailed analysis of the features of the dynamics of the Ukrainian economy.

The Method of Hierarchy Analysis as a Mechanism for Choosing a Development Strategy for a Pharmaceutical Enterprise (p. 117 - 122)
The aim of the publication is to develop a method of hierarchy analysis for choosing the optimal market strategy for the development of a pharmaceutical enterprise. The article substantiates the need for continuous improvement of the decision support system of a pharmaceutical enterprise, which operates in conditions of constant changes in the external environment, to ensure the processes of continuous and stable growth of the enterprise. The main components of the external destabilizing factors of the modern pharmaceutical market, which require the introduction of special mechanisms for ensuring the continuity of the process of managerial changes for the contemporary domestic pharmaceutical enterprises, have been allocated. It is determined that one of the effective mechanisms for choosing the optimal market strategy for the development of a pharmaceutical enterprise is the method of analytical hierarchy as one that is simple in terms of mathematical tools and at the same time gives consistency to the conclusions obtained. The key strategies for the development of a pharmaceutical enterprise include: expanding the range of export-oriented pharmaceutical products; expanding the range of generic pharmaceutical products for sale in the domestic market; building own network of pharmacies for the retail sale of pharmaceuticals both of own production and of other manufacturers. The main indicators of efficiency of the pharmaceutical enterprise in the modern market environment are defined as follows: increase in marginal income; stability of functioning and strengthening of competitiveness; share of the additional sales market. The practical implementation of the method of analytical hierarchy for choosing the optimal market strategy for development is carried out on the example of PJSC «Fitofarm» as a pharmaceutical production and trade enterprise, which occupies a leading position in the pharmaceutical market of Ukraine and needs to maintain and improve it, taking into consideration the influence of modern challenges.

An Analysis of Alternative Methods of Measuring Economic Risk Within the Fuzzy Set Approach (p. 141 - 149)
The article is devoted to the problems of measuring economic risk on the basis of fuzzy sets. An analysis and further development of the methodical apparatus for quantitative assessment of the degree of economic risk is carried out within the framework of the interpretation of the degree of risk as the degree of possibility of discrepancy between the value of the criterion indicator and its normative level. As a direct subject of consideration, the case is taken when there is a simultaneous fuzziness of assessments of the criterion and the normative. The principal emphasis in the study is made on the computational aspect (computational versions) of the analyzed methods for assessing the degree of economic risk. Initially, one of the existing methods for measuring economic risk is considered, the scope of which is the situation when fuzzy assessments of the criterion economic indicator and its normative imply a horizontal, i.e. by levels of affiliation (alpha-levels) way of presentation. Based on the results of the analysis of expressions that define this method, its modification is proposed, which is based on the alpha-level weighing of its basic structural components. Comprehensive attention in the study is paid to the method of assessing the degree of risk for a fuzzy assessment of a criterion economic indicator in relation to a fuzzy assessment of the normative, which is based on a probabilistic analogy. Within this framework, the formulas that form the computing apparatus of this methodical approach are systematized and supplemented. Among other things, the generalized computational formulas of the commented method have been supplemented. For the conditional situation, on the basis of a series of simulation computations, a comparative analysis of the studied alternative methods of measuring economic risk is carried out. The accomplished analysis made it possible to identify certain regularities of the mutual distribution of values of the degree of risk, obtained when they are applied simultaneously.

The purpose of this scientific study is a deep systematic analysis and generalization of existing models for forecasting the bankruptcy of enterprises. In the context of the unpredictability of the world economy, ensuring the stability of enterprises becomes an extremely urgent issue and requires a detailed analysis. For this purpose, the Scopus database was chosen, known for its impressive list of publications in terms of quantity and quality. After a systematic search using 18 keyword combinations, it was possible to identify 1448 potentially relevant publications. However, only 1127 of them met the criteria and were selected for further analysis. The main emphasis of the research was placed on an in-depth study of the characteristics, advantages and limitations of each of the models under consideration. The data obtained made it possible to outline key areas for further research in this area. Testing the models in practice was one further important aspect. For this purpose, data for 2019-2020 were used. Regarding 17907 enterprises, it should be noted that 353 of them subsequently became bankrupt in the period of 2021-2023. Using the Python programming language, a deep statistical analysis and visualization of the results were carried out. Based on the analysis, it was found that some models, including those of Altman, Lees, Springate, Duran, and Tereshchenko, showed impressive accuracy in predicting bankruptcy. Of particular note is the effectiveness of Matviychuk’s model, which showed an accuracy of 67.7%. As a result, this study has made a significant contribution to the development and understanding of approaches to forecasting the bankruptcy of enterprises in Ukraine. The results are of great theoretical and practical importance for specialists in the financial sector, and also lay the foundation for further research in this direction.

Innovation Development of an Enterprise: Modeling Dynamics (p. 162 - 174)
At the present stage of economic development, the leading role in ensuring the competitiveness of both an singular enterprise and the country as a whole, as well as in creating conditions for the transition to sustainable development, is played by the successful implementation of the latest scientific developments in production processes, comprehensive support for the strategy of innovative development. The development and implementation of innovations is a complex dynamic process that requires the use of special research methods. Such a method is system dynamics, which makes it possible to take into account the nonlinearity of the impact of innovation on the state of the economy. The paper considers the methodology for building a model for managing innovation processes, taking into account the self-organization of the logistic type. The main danger that can accompany the evolution of innovation processes is the emergence of unacceptable dynamic modes, so one of the tasks of the study was to determine the conditions capable of ensuring the stability of equilibrium states of a complex dynamic system according to the proposed models. The object of research is a complex dynamic system, between the elements of which there is both positive and negative feedback. To build a model of the dynamics of innovation processes, the mathematical apparatus of the theory of differential equations was applied, which made it possible to consider the development of the innovation process in continuous time. With the help of the instrumentarium of nonlinear dynamics, a study of the stability of diffusion of innovations depending on the parameters of the control influence was carried out. The conditions for the transition of the system to a critical state, which may be accompanied by the occurrence of bifurcations and chaos, have been determined. Particular attention was paid to determining the structural stability of the regulated innovation process in the case when both equilibrium positions are close in terms of parameter values. It is expedient to apply the proposed model to solve the problem of innovation management both at the State level and at the level of an individual industry or an individual enterprise. The obtained theoretical conclusions were confirmed through the use of simulation modeling. Article is written in English

Analyzing the Demand for Educational Services of Higher Education Institutions of Ukraine in the Context of Modern Challenges (p. 174 - 183)
The aim of the article is to study the demand for educational services in Ukraine under the influence of economic, political and social factors that are effective in the country. Among the main factors influencing the demand for educational services are the COVID-19 pandemic, the full-scale invasion of the russian federation on the territory of Ukraine and, as a result, migration processes, the destruction of educational infrastructure, changes in the structure of the labor market, budget constraints, reduction of funding at the expense of households, etc. The projected value of the reduction in demand for educational services (number of entrants) by 2025 based on the studied parameters is on average 10%. A correlation and regression analysis was carried out to study the demand for educational services of higher education institutions (HEIs) depending on the main demographic, economic, political and social indicators. According to the analysis of the correlation matrix, the factors that have a high level of closeness of interconnection and a direct impact on the number of entrants to HEIs are the number of school graduates, the number of population aged 16–59 years and the employment rate. Factors such as a decrease in education costs, the COVID-19 pandemic, and the occupation have an inverse impact on the number of entrants. The paper considers the study of the effectiveness of the State regulation of admission to the budget form of education in individual specialties. For this purpose, data on the results of the 2023 admission campaign from the Unified State Electronic Database on Education were used. It is found that in 2023, the highest demand is for specialties related to the social and philological direction (Psychology, Journalism), as well as those that have a well-established importance in terms of prestige and employment (Dentistry, International Relations, specialties in the IT profile, etc.). On the other hand, the lowest demand is for engineering specialties, where the competition is two applications for three budget-funded places. The article uses econometric methods of analysis of digital information, analyzes the influence model between the indicators of the passing score and the general competition. Recommendations are provided on the revision of the policy of admission and competitive selection of students in certain specialties, taking into account the existing established trends in the demand for engineering specialties and taking into account the factor of occupation of the country’s territory and, as a result, changes in the structure of production and needs in the labor market.

Modeling the Level of Socioeconomic Development of Regions on the Basis of Proxy Variables (p. 187 - 194)
The article proposes models for assessing the level of socioeconomic development and economic security of regions, on the basis of a synthesis of the proxy variable technique and cluster analysis, which allow to assess changes in interregional differentiation, spatial economic transformations, identify «pivotal» regions, assess the level of economic security of regions under conditions of limited data. The system of proxy-variables of socioeconomic development of regions is substantiated; classifications of regions by the level of socioeconomic development on the basis of methods of hierarchical, agglomerative and iterative cluster analysis have been developed; a dynamic analysis of the structure of clusters is carried out; changes in the characteristics of the distribution of proxy-variables are analyzed; an assessment of interregional differentiation and asymmetry of development is carried out. The results of the carried out cluster analysis based on proxy variables helped to conclude that recent years have led to significant transformations of the economic space in the regional aspect. In the cluster of «pivotal» regions, there is a strengthening of the positions of Dnipropetrovsk and Lviv regions, convergence with regions with an average level of development – Kyiv, Kharkiv and Odesa regions. The most critical situation is typical for Luhansk, Donetsk, and Kherson regions. Donetsk region has moved from a cluster of regions with an average level of development to a cluster of regions with crisis development. The relocation of enterprises and smoothing out the asymmetry in the variable of «Growth of legal entities» currently affects the indicators of budget security of the regions to a lesser extent. Kharkiv region, despite the deterioration of the socioeconomic situation, maintains its position in the cluster of «pivotal» regions. The obtained results can be used in the system of anticipative management of regional development to adapt regional strategies to new realities. Article is written in Ukrainian

Improving the Subsystem of Diagnostics and Prevention of Crisis Situations in the Activities of Business Entities (p. 114 - 127)
The article analyzes the current causes of the formation of crisis phenomena in the economy of Ukraine, also the main approaches to assessing the probability of occurrence of a crisis at enterprise. In order to improve the subsystem of diagnostics and prevention of the formation of financial crises, a conceptual model has been developed, which provides for the definition of the class of crisis of industrial enterprises on the basis of cluster analysis. Further, an assessment of the probability of occurrence of crisis situations on the basis of discriminant membership functions is carried out. The application of the conceptual model allowed to develop an approach to improving the system of anti-crisis management of enterprise on the basis of assessment of the sanitation potential of enterprise. A matrix model of choosing the sanitation strategy of enterprise on the basis of positioning of the enterprise in the two-dimensional plane depending on the level of sanitation potential and the class of crisis has been built. The type of sanitation strategy is determined, taking into account the class of crisis, the expedient way of implementing the strategy, corresponding to the actual and potential capabilities of the enterprise and the state of its sanitation potential. The key element of the proposed mechanism is the procedure for selecting and implementing the sanitation strategy depending on: the level of the sanitation potential of the enterprise and the class of crisis; external factors and the class of the crisis. The results of the study can be implemented in the activities of industrial enterprises for the formation and substantiation of crisis management. Article is written in Ukrainian

Cointegration and Causality Relationship of the USA Stock Market with Selected World Markets (p. 128 - 134)
This article, based on data from 1995 to 2022, considers the commercial and economic processes between the USA, Japan and China and stock indexes indicators of these countries. In the course of research, the authors have created multiply regression model, adequacy of the model was determined using the Fisher’s F-test, Student’s t-test, and the stability of the parameters of the regression model was checked using the CUSUM test. Stationarity of the time series was checked by the Dickey-Fuller test. As a result, econometrically sound recommendations are developed, which allows to conduct dynamic analyses to effectively regulate economic processes, integration and international trade, foreign investment operations between the three countries. The Granger causality of the relationship was investigated. Johansen tests were implemented to find the cointegration space, after which a vector error correction model was constructed that describes the long-term equilibrium relationship between the studied indicators and the path to return to the equilibrium trajectory in case of deviation from it. During the modelling, all necessary statistical procedures were used to identify and evaluate the parameters of the model and check its adequacy, accuracy of short-term and long-term forecast values using Eviews 8 tools. The results show that not only for the countries studied here, but also for each country, conduction of monitoring by the governments by using the methodology of the vector model of error correction is very important in order to ensure effective regulation of foreign trade and to participate in regional and global integration processes.

Forecasting the Dynamics of Stockbreeding Development Using Time Series (p. 110 - 117)
The construction of time series using historical data is one of the urgent problems of management in the agrarian sector, since the analysis and forecasting of processes related to the food security of the State, of region, and of economic entities is crucial. With the help of forecasts, businesses can adjust their production activities in such a way as to meet demand and deliver products to consumers on time. The aim of this study is to forecast the dynamics of the development of stock of cattle and cows and to determine the optimal forecasting period. For this type of analysis, statistical methods related to autoregression are used: autoregressive models, moving average models, or combinations of both; integrated models with a variable structure, and models that include seasonal effects and exogenous factors with an autoregressive and moving average component in the model. Monthly statistics on the number of cattle and cows are provided: mean, standard deviation, minimum and maximum values, asymmetry and excess. The dynamics of decline in the number of stock of cattle and cows is shown. The studied series were tested for stationarity. To the time series of the number of cattle, the Box–Cox transformation was applied. The optimal parameters of the models used are presented. Forecast values for time intervals (months) have been obtained and changes in the number of stock of cattle over the past 17 years have been analyzed. The built time series are compared with the actual values, which is illustrated in the graphs. Estimates of standard deviation, mean absolute error for different forecasting terms are provided. When comparing these estimates for different time intervals, the optimal time period for the forecast (24 months) was determined. This study allows farms and enterprises of the industry to realize how much products (milk, meat) can be harvested or obtained in the future. This assists in taking the necessary managerial steps: plan for resource needs, improve efficiency, increase profits, reduce costs, and adapt to changes in the market. Article is written in Ukrainian

A Methodical Approach to Rating Assessment of Competitiveness of Tax Systems of European Countries (p. 117 - 123)
The aim of the study is to develop an alternative scientific and methodological approach to the rating assessment of the level of competitiveness of the tax system of the leading countries of the world. A review of scientific studies devoted to the integral assessment of tax systems of different countries showed a variety of approaches to the choice of indicators and valuation methods. Despite the obvious positive aspects of the methodology for calculating the International Tax Competitiveness Index (ITCI), there are claims regarding the number of indicators and the methods for calculating final scores in subcategories and categories. A methodical approach to an alternative integral assessment of the level of tax competitiveness based on the use of the model of the iterative method of principal components is proposed, which made it possible to compile a ranking of the level of efficiency of the tax systems of European countries in 2023. The presented model is easily implemented without the involvement of special applied statistical programs. Ukraine (like most countries with developing economies) is not yet among the 38 countries of the Organization for Economic Cooperation and Development, so the official ITCI index for Ukraine can only be calculated unofficially. The taxation system of Ukraine is characterized by both positive indicators and some shortcomings. Therefore, in order to improve the tax system of Ukraine, it is necessary to study the positive and negative experience of other countries and determine the factors influencing the country’s position in the ranking of international tax competitiveness. In the course of further research, it is necessary to critically review the system of indicators, excluding the ones that do not significantly affect the final result, but can lead to certain errors.

Modeling the Factors of Socioeconomic Development of the Regions of Ukraine and Determining the Role of ICT (p. 111 - 117)
The aim of this article is to analyze and model the factors of socioeconomic development of the regions of Ukraine, taking into account the peculiarities of the influence of information and communication technologies (ICT). The article is directed towards identifying the relationship between various aspects of regional development and the introduction of ICT, as well as determining the role of these technologies in increasing the competitiveness and sustainable development of regional economies. One of the tasks is to reveal the importance of information technology for the effective management of regional development and to develop recommendations on strategies for improving the efficiency of the use of ICT in order to promote sustainable development of the regions of Ukraine. In order to determine the generalized factors of socioeconomic development of regions and to establish the impact of ICT on this development, a model of the main components has been built, which has allowed to transform the 16-dimensional feature space into a four-dimensional space of generalized factors that explain 88.7% of the variation of the features selected for analysis. This indicates a high level of factorization of the built model of principal components. The following generalized factors have been identified and ranked according to the degree of importance: 1) development of ICT and labor potential (impact: 39.9%); 2) the state of finance and investment (impact: 14.4%); 3) development of production (impact: 24.7%); 4) the results of the functioning of enterprises (impact: 9.6%). The computations were carried out using the «Statistica» application package, in particular the «Factor analysis» module. The use of the developed model made it possible to prevent subjectivism in determining the main factors of socioeconomic development of the regions of Ukraine. The carried out research allowed to substantiate the theoretical and methodological foundations of statistical modeling of factors of socioeconomic development of regions and to determine the role (impact) of ICT. The allocated factors can be taken as a basis for the formation of key directions and strategies for the development of regions, as well as for making effective managerial decisions in the field of ICT.

Modeling of Sustainable Economic Development in Terms of the Resource-Ecological Component (p. 183 - 192)
The purpose of the study is to reflect the relationship between economic development and environmental pollution. To achieve this goal, a simulation model of ecological and economic processes has been built. The article discusses general economic reforms that lead to unforeseen damage to the environment. Therefore, the existence of outdated policies, market imperfections, and organizational structures elsewhere in the economy can interact in unpredictable ways with broader economic reforms and create incentives for overuse of natural resources and environmental degradation. That is why the correction of such a situation usually does not require the abandonment of the original economic policy. When conducting simulation experiments, the whole range of possible pictures of the model’s behavior is obtained by varying the coefficient of choice of the strategy, which is a managerial one. The built model reflects the ecological and economic processes associated with air pollution and purification in a certain area based on the specified initial conditions and time series that describe the dynamics of exogenous variables. The model proposed in the study allows predicting the dynamics of endogenous variables (qualitatively and quantitatively), and this behavior is possible with the unchanged structure of the system, and quantitative estimates are reliable until 2040 (further, the dynamics of the main variables is provided to demonstrate the possible S-shaped behavior of the system). The model presented in the paper reflects the relationship between different subsystems (sectors of the economy) with the help of feedback loops and allows to consider the influence of selected subsystems (one on the other), which cannot be done with the help of classical methods used in economics. The built model makes it clear that in order to maintain the ecological balance in the world, the situation will require a serious increase in investments in the development of environmental technologies and reduction of environmental damage from existing production technologies.

Modeling the Impact of Climate Change on the Productivity of the Agrarian Sector (p. 146 - 151)
The article proposes a conceptual approach to modeling the impact of climate change on the productivity of the agrarian sector, substantiates the factors of climate change, and forms the information base of the study. Specifically, rainfall data was taken from the Climate Hazards Group InfraRed Precipitation with Station database (CHIRPS), which is a quasi-global dataset of precipitation amounts over 30+ years. CHIRPS incorporates 0.05° resolution satellite imagery together with data from local stations to create gridded rainfall time series to analyze trends and monitor seasonal drought. In order to obtain rainfall data for each of the selected countries, the Large-Scale International Borders (LSIB) database was used. This data is taken from two other datasets: the LSIB Lines Vector File and the World Vector Shoreline (WVS) from the National Geospatial-Intelligence Agency (NGA). Additional precipitation information was obtained using the Google Earth Engine after performing procedures with a sample of geolocation data for each country, obtaining actual precipitation data for the observation period, exporting the data and processing them to bring the results to the annual figure. The formed information base on the factors of climate change has allowed to develop models of productivity of grain production in the countries that are the largest wheat producers in the world. The results of the development of models led to the conclusion that climate change affects crop yields in countries that are leading producers of cereals. The obtained results can be used to predict changes in yield and production depending on climatic parameters such as temperature and precipitation, as well as to determine the optimal and extreme values of climatic factors.

The Neural Network Predictive Technologies for Crisis Classification and Bankruptcy Assessment of Trade Industry Entities (p. 196 - 206)
The ongoing war in Ukraine has led to a significant increase in the number of business bankruptcies. Timely assessment of bankruptcy risk is critical for making effective management decisions. The aim of the study is to develop an adaptive model for assessing the propensity of an enterprise to bankruptcy based on fuzzy neural networks, taking into account the specifics of the Ukrainian market in wartime. To achieve the aim, several stages were carried out: formation of a sample of enterprises in the trade industry; determination of crisis classes using cluster analysis; building a fuzzy neural network using the Fuzzy Logic Toolbox package in MATLAB; training the network on historical data and testing on new data. At the first stage, a sample of enterprises is formed, with the help of which the model will be trained. At the second stage, classes of crisis (threat of bankruptcy) are formed. At the third stage, with the help of the apparatus of fuzzy neural networks, a membership function with a certain set of parameters is formed. With the help of this function, it is possible to attribute this or that enterprise with a certain degree of belonging to one of the classes of crisis formed at the previous stage. The fourth stage is to check the adequacy of the obtained model and the possibility of its practical use. At the fifth stage, the practical implementation of the model is carried out: with the help of the membership function, the propensity of the researched enterprise to bankruptcy is determined, that is, to what extent the studied enterprise belongs to one or another class of crisis. As a result of the application of the proposed algorithm, a fuzzy neural network was built, which used the financial indicators of Ukrainian enterprises. To train the model, a dataset was used that included 12 enterprises in the trade industry. The developed model allows to classify enterprises by the level of financial sustainability with high accuracy. Fuzzy neural networks have been shown to be an effective tool for predicting bankruptcy under uncertainty. The use of fuzzy neural networks made it possible to take into account uncertainty and adapt to changes in the external environment. The obtained results indicate the perspective of using fuzzy neural networks to assess the financial sustainability of enterprises. The developed model can be used as a tool for early detection of signs of crisis and making timely managerial decisions. Article is written in Ukrainian

Modeling the Impact of Foreign Direct Investment on the Economic Development of Countries (p. 165 - 174)
The article examines the impact of foreign direct investment (net inflows, net outflows) on the economic development of countries with an emphasis on modeling this impact through the gross domestic product (GDP) indicator. The aim of the study is to develop econometric models that allow to quantify the contribution of foreign direct investment (FDI) to the economic development of countries, in particular Ukraine, the countries of the European Union and the world. To achieve the aim of the study, the methodology of correlation and regression analysis was used, which made it possible to identify the relationship between FDI and the economic development of countries, to assess the significance and efficiency of foreign investment. Paired linear regression equations have been built, the significance and quality of the parameters of econometric models have been checked, in particular, the values of the correlation and determination coefficients have been calculated, and the relationship between the resulting features and dependent variables has been assessed. With the help of the Student’s t-test, conclusions are made to confirm the statistical significance of the model regression coefficients, and through the F-test, the statistical reliability of the regression equations is verified. An analysis of the impact of FDI on the GDP of Ukraine, the EU and the world revealed significant differences in the relationship between these economic variables, which can be explained by different economic and structural features. The greater impact of FDI on Ukraine’s GDP compared to the EU and the world is due to the economic structure, the level of investment attractiveness, the need for external capital and vulnerability to external shocks. It is found that a significant part of Ukraine’s GDP depends on foreign investment, which stimulates economic growth by creating new enterprises, jobs and increasing productivity. The outflow of FDI from Ukraine has a direct impact on the economic stability and investment attractiveness of the country. The article emphasizes the need for a systematic approach to modeling the impact of FDI on GDP, which will contribute to more effective economic development and stability of countries. The results of the simulation can be useful for governments, enterprises and investors in the formation of strategies for attracting and managing foreign investment. Article is written in Ukrainian

Multifactor Model of Assessment of Risks and Their Impact on the Economic Security of Enterprise (p. 148 - 153)
The article is devoted to the development of a mathematical model for assessing the risks that may affect the agro-industrial enterprises of Ukraine. The article highlights the need to take into account external and internal factors, such as economic, military, material, technical, technological and climatic risks, which significantly affect the activities of agricultural enterprises in modern conditions. The main aim of the study consists in building an effective multifactor model of risk analysis and forecasting, which takes into account the weight of each risk, the probability of occurrence, and the impact on the economic security of enterprise. To do this, it is proposed to use the cumulative risk indicator (R), which is calculated on the basis of the weight of each risk (Wi), its probability (Xi) and its impact (Si) on the financial stability of the enterprise. The authors examine in detail different types of risks, including economic ones, such as exchange rate fluctuations and rising resource prices; military risks associated with possible losses as a result of hostilities; logistics risks, such as port blockades and export disruptions; technological risks associated with outdated equipment and problems of access to the latest technologies; climate risks caused by adverse weather conditions. Each of these risks has a different level of impact on the economic security of enterprise, which is taken into account in the developed model. The article emphasizes that the application of the multifactor model contributes to improving the efficiency of managerial decisions directed towards minimizing risks and ensuring the stability of enterprise. Thanks to the flexibility of the model, businesses can adapt it to their specific conditions, adding new risks or changing the weights of existing ones, and thus making it versatile. Additionally, the model allows for real-time risk monitoring, which helps businesses respond quickly to changes in the external environment and make informed strategic decisions. Summing up, it can be said that the multifactor model proposed in the study is a significant tool for reducing uncertainty and increasing the resilience of agro-industrial enterprises to risks both at the internal and external levels. Its versatility allows for the assessment of short-term threats and for long-term forecasting, which is crucial for planning the sustainable development of enterprises in unstable conditions.

Application of Machine Learning Methods in the Algorithm for Finding Partners for Collaboration on the Example of the Retail Sector (p. 153 - 161)
Retail companies play an important role in the global economy by meeting the daily needs of consumers. During the general economic crises, these companies demonstrate relatively smaller «setbacks» compared to the market, but, on the other hand, such a factor of stability is also a certain limiter of growth. Therefore, it is very common for companies to collaborate with each other, creating business collaborations to expand their market and achieve joint growth and success. The aim of the study is to develop and implement an algorithm for finding partners for collaboration. The proposed algorithm contains the following steps: formation of the research information base; preliminary statistical analysis of the generated dataset; classification of objects in the multifactorial feature space; assessment of the quality of classification; substantive analysis of the obtained classification; ranking objects within the cluster group and selecting candidates to create a collaboration. The algorithm is implemented for the output dataset of companies in the retail sector, which were part of the SP500 index as of the beginning of August 2024. The initial dataset contained information on the values of such financial and economic indicators as: dividend income, price/net profit ratio, return on assets, return on equity, profit margin, debt-to-equity ratio, price/revenue multiplier, price/money flow multiplier, price/book value multiplier, share of equity capital, current liquidity ratio. The implementation of the algorithm allows you obtaining a quantitative assessment of the suitability of the analyzed company for participation in the collaboration. Such a quantitative assessment is obtained as a result of the implementation of machine learning algorithms, namely, the k-medoids algorithm, which allows classifying the objects of study into relatively homogeneous groups, as well as identifying a representative of each group, whose coordinates play the role of a cluster centroid.

Stability of Equilibrium and Bifurcation Behavior of the Production and Economic System (p. 161 - 170)
This study considers some key problems of analysis of nonlinear dynamic systems on the example of production and economic objects. The construction of a mathematical model of systems, functioning in the market environment, is aimed at qualitative forecasting (along the development trajectory) of the behavioral properties of such a system. The conceptual orientation of the study involves the analysis of structural instability of equilibrium states within the framework of the proposed model by the presence of characteristic combinations of the most important economic parameters that have a significant impact on the static and dynamic characteristics of the production and economic system. Critical modes of functioning of the object have been identified and its stability area has been built in three-dimensional space depending on significant parameters. An example of such dynamic modes, which were revealed in the process of analysis using the proposed model, is an unstable boundary cycle that provokes the so-called «hard» mechanism of excitation of self-oscillations around the equilibrium state of the «focus» type. Also in this system, the global bifurcation of the saddle joint in the presence of a loop of the «saddle» separatrix around the state of equilibrium was found and studied. Such modes are rather dangerous, since there are cyclic processes with very long periods, which significantly affects the accuracy of predicting the behavior of the object under study.
