摘要:The article examines the system of interaction of control and supervisory services and structures (CSS) in the process of managing the development of socio-economic systems (SES). The system of interaction of the CSS is considered as a complex independent dynamic regulated process. The new concept of “synergy management system (SMS) of interaction” of control and supervisory services of complex socio- economic systems is substantiated. The basic principles and structure of the organization of the system of management of synergy of interaction of CSS are proved. It is noted that in the theory of complex synergetic systems, an important place belongs to the processes of self-regulation in local areas. It is shown that the existence of mechanisms for implementing self-regulation indicates the maturity of synergy management systems. The essential functions and principles of the organization of the system of interaction between control and supervisory services are highlighted, and the concept of complexity and maturity of this system is revealed. Methods of reducing the risks of possible implementation of negative events when coordinating within a self-regulating system for managing the synergy of interaction of subsystems are indicated. It was also emphasized that a mandatory aspect aimed at establishing the work of the SMS is a methodically based assessment of the effectiveness of the management systems for the synergy of interaction between control and supervisory services.
