Methods for synthesis of informational and technical structures of critical application object’s control system

Abstract

The subject matter of the paper is the processes of synthesis of the structures related to control system (CS) for critical application object (CAO). The goal is to develop the methods for CAO CS’s informational and technical structures synthesis. The tasks to be solved are: 1) derive formalized descriptions for the problems, which occur during the synthesis of CS’s organizational structure; 2) choose the optimal structure of the computer system (CompS), which ensures the operation of the CAO CS and its subsystems; 3) derive formalized descriptions for the problems, which occur during the synthesis of the technical structure of the CAO CS CompS. For this purpose, methods of the theory of sets and integer programming with Boolean variables were used. The following results were obtained. The methods for CAO CS’s informational and technical structures synthesis are obtained. The first of them takes into account the problems of CS components control, the algorithms and methods for solving problems, as well as the distribution of tasks among the components during their solution. Formulated quality criteria and possible constraints. Separately raised the problem related to the synthesis of the CS’s organizational structure, which is one of the fundamental. The second method consists of two steps, which include the synthesis of the smallest possible set of components for the implementation of the CS, their location within the corresponding CompS, the number and nature of the interconnections between the components, as well as the synthesis of acceptable options for the implementation of each component and interconnections. Conclusions. The scientific novelty of the obtained results is as follows: the methods for synthesis of theCAO CS’s informational structure and the corresponding CompS’s technical structure, which underlies the CS, are first developed.
