The article considers the issue of substantiating reliability indicators in the design of military automotive equipment based on the study of mathematical models of their functioning. The solution of the optimization problem of choosing the standardized reliability indicators for the developed MVS products based on the available mathematical models depending on the functional purpose is shown. A comparative analysis of the main methods for setting trends to the reliability of MVS (expert assignment of trends, assigning trends to the closest analogue, setting the optimal level of reliability of products as a whole) is carried out. The general principle of choosing a rational (minimum necessary and sufficient) nomenclature of assigned PNs is that in each specific case, military automotive equipment (MVS) products are classified sequentially according to the established attribute characterizing its purpose, specified (assumed) operating conditions, and so on. Further, depending on the totality of classification groups to which the product is assigned, using a work table, a set of indicators to be defined is determined. The optimal dependence “reliability (R) − cost (C)” is considered, which is used in substantiating trends to the reliability indicators of products (the dependence is built). The dependence of cost costs C (R) and technical efficiency W (R) of the product is considered. Further, depending on the totality of classification groups to which the product is assigned, using a work table, a set of indicators to be defi ned is determined. The solution of the problem is shown, depending on the availability of the models “reliability-efficiency”, “costsreliability”. For the best solution to the problem, the use of the FOREL1 taxonomy algorithm is proposed. The results of solving this problem may provide an opportunity to develop organizational and technical measures to improve the design of MAE products and regulatory documents on the operation and repair of military automotive equipment.
