Finding problem of mean operating time between failures of restorable system with load-mixed reserve, common and individual switches is considered. The aim of the article is to obtain correlations allowing to estimate mean operating time between failures of this system with redundancy ratio m = 2 taking into account switches unreliability. Markovian model of system reliability is used. As a result of problem solution the expressions for calculating mean operating time between failures, estimation of reliability gain to it from considering system application as compared with restorable system with loaded reserve are obtained. These expressions may be used with any type of reserve on a load and with the execution of the assumptions received.
Key words: reliability, redundant restorable system, load-mixed reserve, common and individual switches, mean operating time between failures, reliability gain to mean operating time between failures.
