“…The calculation of indicators of reliability and cost of operation (determination of MC parameters) must be performed at the stage of product design. Thus, there is a problem of optimizing the characteristics of the product (system) and the parameters of its MC, while maintaining the technical characteristics within the established limits [1][2][3][4].…”

The problem of extending the service life of complex radio-electronic products and systems remains relevant in our time. Life extension is based on the effective operation of maintenance and repair systems. Each of these systems has its own strategies with corresponding parameters, and these parameters should be different for different products. The criteria that determine the parameters of these systems are often the criteria for minimizing the unit cost of operation and increasing the coefficient of technical utilization. The choice of criterion is determined by the nature of the tasks that the product (system) solves. Also, the parameters of the reliability of the product are significantly influenced by the parameters of the reliability of its component parts, as well as the correct design decisions.The article solves the problem of developing an algorithm for optimizing the parameters of the maintenance process of a radio-electronic product (system) using a maintenance strategy based on a condition with a constant monitoring frequency. The algorithm was developed for the criterion of minimizing the unit operating cost of an object, which is determined for a given period of operation, while ensuring a given requirement for the level of reliability of the object.

The article is devoted to the development of a method for substantiating the requirements for the survivability of a promising automated command and control system. It is known that one of the priority tasks of the country's defense is the creation of an effective command and control system for the Armed Forces of Ukraine based on modern information technologies. But, despite this, its current state, for a number of reasons, does not fully meet the requirements for it. An important reason for this state of the command and control system of the Armed Forces of Ukraine is the imperfection of the methodological apparatus that is used in the study of the command and control process and the justification of the requirements for a promising ACS. One of these important requirements is the requirement for its survivability. The currently existing methods for substantiating the requirements for the survivability of a promising ACCS do not have a single ideology of construction and do not allow studying the functioning of the ACCS in time under the conditions of the complex active influence of the enemy. To achieve the goal of the article, its author has developed a new method, the feature of which, which determines its novelty, is that it provides a comprehensive account of the enemy’s influence on the survivability of control points of a promising automated control system in two main areas: fire damage to control points and radio suppression of ultrashort-wave, short-wave radio communication channels with control points. The method is based on a mathematical model of failure of the control points of a promising automatic control system due to fire damage by the enemy and its restoration. This model, unlike the existing ones, allows you to determine the change in the state of the control system over time. Also substantiated is the relationship between the number of required ultra-shortwave, short-wave radio communication channels with the launcher of a promising automated control system and their reliability.
