Evolutionary Approach to the Concept of Robust Control of Economic Systems
A.A. Tropin, E.V. Freydina, Mikhail AlekseevFundamental goal-setting of the functioning of economic systems is manifested in the intention for the sustainable development in the environment which is represented by “chaos” and is filled with uncertainty and the fundamental goal-setting is limited to “fundamental stochasticity” and “fundamental instability”. This feature stimulates the development of theoretical and practical aspects of new control mechanisms which include robust control that is a control configured to dampen uncertainty in an application to open systems. The article considers the development of the concept of robust control of economic systems in the continuum of fundamental paradigms “subject-object”, “subject-subject” and “subject-polysubjective environment” which determine the evolutionary view of control. The research is aimed at revealing the changing environment of the functioning of economic entities and developing models of reflexive and robust control of their interaction. The model of market (polysubjective) environment used in the analysis takes into account the chaos and uncertainty and reflects the fundamental characteristics of the behavior of market participants: the existence of different pictures of subjective perception of the surrounding reality, the need for decision-making in the conditions of uncertainty, the emergence of reflexive processes that accompany the interaction of market actors. The methodology of introdu robust control into the polysubjective environment is based on the approach to structuring a reflexively active method, where the business situation, regarded as the carrier of uncertainty, and the elementary organizational structure, is the "subject-subject" interaction as its elementary organizational structure. The action in the context of "subject-subject" is determined by the generated model of reflexive control, which differs from the model of J. Soros, by the introduction of an interpreting function. It is shown that the result of interaction between economic entities is a random variable and to assess the admissibility of making a decision in the "point of agreement" it is necessary to seek compliance of the meeting result with the constraints imposed by the robust limit. The image of the process of generating control actions is represented by means of functions of reflexive governance acting within the limits of a robust limit.
