Abstract. The features of solving problems related to the optimization of information transfer processes in cyber-physical systems at manufacturing enterprises are considered. A multi-stage process of making an optimal decision on the formation of a cyber-physical system is presented, the use of which makes it possible to overcome the difficulties associated with the large dimensions of the analyzed problem. Conditions imposed on the controlled parameters are revealed. A set of restrictions in the system is presented. A block diagram of the process of making an optimal decision reduced to a certain procedure, is given. A principle of constructing a generalized efficiency criterion is shown. A set of extremal problems used in the course of a cyber-physical system analysis is formulated. On the basis of a system of functional equations presented in the form of recurrent relations, realization of the optimality principle is demonstrated. The features of costs distribution by resources in a cyber-physical system are considered and an example of the rational use of modular capacities in the overall structure of the system is given. The results of mathematical modeling are presented to demonstrate the possibility to increase the efficiency of the data transmission process.

Keywords: cyber-physical system, process, optimality, optimization, modeling
