The article offers an algorithm for determining the optimal variant of reserving elements of a complex technical system. The purpose of this work is to develop an algorithm for selecting a backup scheme for a complex technical system, taking into account the reliability of its operation. since increasing the reliability of technical devices is achievable by reserving, and the types of reserving are different, there is a need to choose a backup scheme that provides the required reliability at minimal cost. The reliability of the system is determined by the reliability, maintainability, preservation, and durability of its parts. It depends on how the elements that make up it are combined and to what extent the correct operation of each element is necessary for the operation of the system as a whole. Redundancy allows you to most fully solve the problem of obtaining the required reliability of a complex technical system with relatively unreliable elements, increasing, on the one hand, reliability, and on the other – maintainability. Redundancy allows you to increase the reliability of a complex technical system on the one hand by replacing a faulty element with a serviceable one, and on the other – by allowing maintenance and repair of its elements without discontinuing the use of the system for its intended purpose. To determine the effect of applying redundancy, it is necessary to assess the reliability of the system when applying various redundancy schemes. The redundancy scheme defines the type of redundancy for each element of a complex technical system and the number of redundant elements.
