Optimisation Model of Distribution of Investments between Business Directions of a Diversified Enterprise (p. 133 - 139)
The article is devoted to problems of distribution of investments between business directions of an enterprise, namely – a search for their optimal correlation with the aim of maximisation of the expected profit or minimisation of risk. The goal of the article is adaptation of instruments of the theory of portfolio investments, in particular, methods proposed by H. Markowitz and W. Sharpe, to the process of building an optimal business portfolio of an industrial enterprise. In the result of the study the article offers methods of assessment based on establishment of a regression dependence between results – profit and factors – investments and also between their changes. The proposed methods give a possibility to determine change of values of profitability of a business portfolio from change of volumes of investing when there is no mathematical dependence between them, it facilitates a better identification of competitive advantages of a business portfolio and, as a result, increase of its stable predictable development. The article builds a mathematical model of optimisation of distribution of investments by business directions, which takes into account the market situation and also distribution of investments between strategic business units during previous periods. Based on analysis of mathematical forecast models the article formulates an optimal strategy of identification of the business portfolio structure.
Keywords: business portfolio, optimisation model, profit, risk, regression dependence, investment volume
