ABSTRACT
A schematic diagram of the polystructural system is presented. The implementation of the principle of process-functional management of the elements of the polystructural system is described. The methodology of organizing information flows and their intelligent processing in the process-functional model of management of the elements of the polystructural system is presented. The organization and architecture of the polystructural system are considered. The metrological aspect of the construction of the polystructural system is described. The roles of digital twins of the elements of the polystructural system and their interaction with the body of the polystructural system are defined. The mechanism of interaction between digital twins of the body of the polystructured system with the goal tree of the polystructure and digital twins of its constituent elements is presented. Three models of behavior of control systems of objects of digitalization based on their digital twin are considered. The issues of system development prediction accuracy by means of digital twins are considered; the role of digital twin metrology is shown. The interaction of digital twins to achieve the overall goal of the system and the goals of individual digital objects in their relationship is considered. As an example of the application of the proposed theory, the management of a smart home through interacting digital twins is considered. The smart house is considered a polystructural system in which the interaction of its components occurs through the energy and information flows of the elements of the polystructural system, taking into account the physical processes taking place.
