MODELING PROCESSES IN A CYBER-PHYSICAL SYSTEM USING A SIMULATION APPROACH

Abstract

Background. Cyber-physical systems are currently actively spreading in various fields. In order to carry out their effective management, it is necessary to use approaches based on simulation modeling. The corresponding task is considered in the paper. Materials and methods. The paper discusses the problem of modeling processes in the cyberphysical system. A set of stages that are used in the course of choosing characteristics related to its management is given. In the first step, the variables are selected. At the second stage, the methods to be used in the simulation are selected, taking into account that the processes taking place in the cyber-physical system, as well as external influences, are accidental. In the third stage, homogeneous components in the cyberphysical system are selected. At the fourth stage, based on the average values of the amount of transmitted data in the cyber-physical system, the value of its efficiency is determined. The structure of an algorithm that makes it possible to distinguish homogeneous modules in a cyber-physical system taking into account the influence of external factors is given. The features of a simulation experiment for a cyber-physical system using an optimization model are indicated. The stages on the basis of which the choice of the quasi-optimal option for the placement of modules in the cyberphysical system based on simulation methods is carried out are noted. Results. Simulation of a cyber-physical system with specified characteristics is carried out. It is shown that using the proposed approach it was possible to increase the efficiency of the system. Conclusion. The results of the work can be used to simulate a wide class of cyber-physical systems. The presented modeling algorithm is universal.
