Recently when developing the onboard management information equipment modules of commercial execution ready to application (to Commercial Off The Shelf - COTS) are widely used. COTS products differ the wide nomenclature, lower prices, first of all because of advantages of mass production, with shorter terms of development and the modernization, the best program support, continuity which interferes with moral obsolescence of used technologies and provides that the bigger term of operation. However increased requirements on resistance to climatic and high-rise service conditions can nullify all these numerous advantages of standard serial components. For permission of this contradiction the methodology of NDI (Non-Developmental Item) "not developed anew" the products, guaranteeing 100% compatibility of modules commercial (civil) and military was offered. Today the methodology of NDI became a basis of formation of technical policy on creation of the military modern systems, accepted by the vast majority of the large contractors creating final systems in interests of air forces of foreign countries. The algorithm of support of decision-making stated in this article allows to reduce significantly computing expenses as doesn't demand repeated calculations for various combinations of varied parameters, and can be used for design of systems of support of decision-making.
