Generalized Theoretical Models of Cyberphysical Systems

Purpose of research. The purpose of this article is to attempt to unify the existing views of cyberphysical systems, introduce formal models of cyberphysical systems, and consider similarities and differences between this concept and related information technology concepts. 

Methods. The paper considers the existing views of cyber-physical systems, their relationship with related information technology concepts, in particular, with the "Internet of things". To solve the problem of decomposition of the visions of these systems, we used the tools of system analysis and the set theory framework. 

Results. The paper describes high-level and set-theoretic models of cyberphysical systems. The high-level system model describes the relationship between users, converters, and the logical and physical levels. Converters are the centerpiece of cyberphysical systems; they are designed to interact between logical and physical components and are sensors and agents. The set model of cyberphysical systems takes into account the possibility of exchanging energy and information between components. Besides, the paper offers a generalized dynamic model of the cyberphysical system functioning that reflects the processes of changing the state of its components under the influence of the environment and internal factors. 

Conclusion. The proposed set-theoretic model is the basis for developing and describing the behavior of cyberphysical systems. This model describes the relationship of components of cyberphysical systems and shows the impact of one of the parameters on all functional components with which this parameter is associated. Thus, in order to "intellectualize" the environment, it is necessary to develop a number of requirements that take into account the specifics of functional components and the role of users, which will allow implementing data management services based on data about the environment, user behavior, interests and preferences.
