摘要

In this paper a cold standby repairable system with geometric process exposing to Weibull failure law, consisting of two identical components and one repairman is studied. Assume that each component after repair is not as good as new. Under this assumption we study an optimal replacement policy N in which we replace the system when the number of failures of component 1 reaches N. We determine an optimal repair replacement policy N* such that the long run average cost per unit time is minimized. We derive an explicit expression of the long-run average cost and the corresponding optimal replacement policy can be determined analytically. Numerical results are provided to highlight the theoretical results.
