Reliability and Maintainability Requirements for Mobility Means of Surface-to-Air Missile Systems

: The article solves the problem of complex substantiation of reliability and maintainability requirements for mobility means of surface-to-air missile (SAM) systems considering hierarchical structure of mentioned systems and appropriate characteristics of their mobility means, minimum configuration of SAM system means for air defense operation and a number of tactical characteristics of operation area. The quantitative characteristics of effectiveness of SAM system mobility means are measured by the coefficient of effectiveness sustainment which is the ratio of initial effect considering reliability and maintainability of mobility means to its value in case of faultless mobility means. The developed mathematical models, which are proposed for further use as a program product, are designed for defining the limit values of such reliability measures as mean range between failures and mean recovery time of combat and technical facilities of SAM system corresponding to given values of coefficient of effectiveness sustainment.
