Abstract
Common principles of substantiation of reliability requirements for vehicles (mobility means) of surface-to-air missile (SAM) systems are discussed. The principles mentioned include the impact of a hierarchically-branched structure of SAM system and reliability of their vehicles on system effectiveness under the real conditions. As the complex measure of SAM system effectiveness the coefficient of effectiveness sustainment of SAM system combat (technical) mobility means is used, which is the ratio of system output effect characteristic taking into account reliability measures of mobility means to its value in case, when mobility means do not have failures. The coefficient used here is considered to be the function of mean distance between failures (MDBF) of mobility means and their number.

Modern experience of local wars and conflicts testifies to necessity of high mobility of military equipment in order to improve their survivability
Our article is devoted to the developing the method for substantiation of reliability requirements for mobility means of surface‐to‐air missile (SAM) systems, which takes into account their hierarchic structure as well as the influence of the SAM system mobility means reliability on the system effectiveness
Due to the complexity of SAM systems, it is advisable to evaluate the mobility means influence on the whole system performance using the coefficient of effectiveness sustainment (Keff), which can be calculated as the ratio of the target output characteristic (Eim) that accounts for the imperfection of the vehicles to its value (Eid) in the ideal case, when mobility means do not have any failures, or: Keff
Summary
Modern experience of local wars and conflicts testifies to necessity of high mobility of military equipment in order to improve their survivability. 92 P.V. Open’ko, P.A. Drannyk, V.V. Kobzev, M.B. Brovko and G.S. Zalevsky ated with the necessity to substantiate requirements for their vehicles (mobility means) intended to provide mobility [1, 2]. The problem of substantiating the dependability requirements [3, 4] for mobility means of SAM systems, to which design and technological solutions, implemented by the motor vehicle chassis designer must comply with, needs more detailed research. The developed method for substantiating the reliability requirements for mobility means of SAM systems, which accounts for the functioning peculiarities of the mentioned systems, is described in the article
