Abstract

A model of a system with dual (active and standby) redundancy of the components in different subsystems, which significantly enhances its reliability, is considered. The basic formulas have been obtained for the calculation of the reliability function of the system depending on the multiplicity of the active and standby redundancy in the subsystems. The problem of constructing the lower confidence bound for the reliability criterion, which is the probability of the failure-free operation of the system for a preset time, has been considered. Approximate asymptotic expressions, for the case of high reliability, have been obtained for the reliability function of the system and its lower confidence bound.
