SYSTEM APPROACH FOR SOCIAL AND ECONOMIC SYSTEM RESEARCH
All the social and economic systems are complex dynamic systems. One of the most important peculiarities of such systems is a big number of feedback networks and strong interaction between system parameters. There are practically no independent control parameters in such systems. It leads to occurring of the periods of unexpected random behavior. The goal of the research of the systems is beyond formal performance and considerably limits possibility of application of mathematical methods of system behavior description based on statistical material. Search of solution of the problems led to development of the specialized method of simulation modeling which is called «system dynamics». With the use of mental models of researchers, this method makes it possible to create simulating models of complex systems as compositions of feedback networks and to study dynamics of development of the systems experimenting with their models.
