Article Abstract

* - Research work for this paper was carried out under NSF Grant GK-19537.** - Billy Claybrook's help in computer programming is gratefully acknowledged.In this paper, the reliability of a system with N independent components supplied with a pool of s spares is investigated. The components have an exponential life time distribution and the failed components are repaired, one at a time, with a general repair time distribution. Numerical results are presented or the mean time to system failure (system is said to fail when a component fails with no spare available) and the reliability of the system in some special cases of interest.
