BASIC PROVISIONS OF THE SCIENTIFIC AND METHODOLOGICAL APPARATUS OF THE SUBSTANTIATION OF THE STRUCTURE OF THE LOCAL COMPUTER NETWORK OF THE COMPLEX OF AUTOMATION OF THE CONTROL POINT OF THE ANTI-AIR DEFENSE
The work proposes a scientific and methodological approach to solving the problem of substantiating the composition, structure and methods of organizing the fault-tolerant functioning of the local computer network of a complex of automation tools for an air defense connection control center in difficult conditions for its use. Justification of the structure of the local computer network of a complex of automation tools involves improving, on the one hand, models for evaluating the effectiveness of its functioning under the influence of destabilizing factors, and on the other, methods for structural and parametric optimization of a complex of automation tools. This approach allows, under conditions of restrictions on the parameters of the used technical means, to ensure: at the design stage - minimization of the cost of a complex of automation means, while fulfilling the quality requirements for solving control problems, and at the operation stage, under the influence of destabilizing factors - maximization of its performance indicator. The task of substantiating the structure of the local computer network of a complex of automation tools is reduced to solving three private subtasks. The first two are solved at the design stage: the synthesis of the rational structure of the local computer network of a complex of automation tools, which provides for the search for a rational composition of the used electronic computers and the distribution of tasks among them, which ensures the minimum cost of creating a complex of automation tools; the task of justifying the means and methods of organizing the fault-tolerant functioning of the complex of automation means, which consists in finding a rational option for backing up electronic computers of the complex of automation means and the option of using program-logic methods that ensure the minimum cost of means and methods to achieve a given value of the probability of successful solution of all functional tasks of the complex . The third task is solved at the operational stage and consists in justifying the option of distributing tasks among electronic computers of a complex of automation tools in case of failures in some of them. The proposed scientific and methodological apparatus will improve the efficiency of the complex automation equipment with numerous destabilizing factors due to the limited values of the reliability characteristics of its elements.
