System-dynamic Models in Forecasting Development of Complex Economic Systems (p. 121 - 132)

The goal of the article lies in consideration and justification of possibilities of use of the system-dynamic approach in forecasting development of a complex economic system using example of dynamics of a sea port. Generalising scientific works of many scientists, the article holds that the necessary condition of development of minimalistic models, adequate to real systems and set tasks, is a proper selection of methodology of modelling, relevant software and plans of conduct of simulation experiments. The article justifies expediency of use of the system-dynamic methodology depending on the level of abstraction and degree of aggregation of the studied processes. The article offers a set of models directed at forecasting dynamics of the operation activity of a port and connected financial flows for various time prospective. The article shows a general structure and fragments of flow charts of a model of long-term forecasting the port development dynamics. Operation of the model is presented by results of simulation experiments using example of the “Sea Trade Port Ust-Dunaysk” State Enterprise. Simulation experiments are realised on the Ithink software platform and facilitate identification of general tendencies of object functioning and detection of the most significant weak points.
Keywords: simulation model, simulation experiment, system dynamics, flow chart, forecasting
