摘要

本文提出了一种改进的预防性维护(PM)策略，该策略只能在计划时间nT (n = 1,2，…)进行:当且仅当故障总数超过指定数量k时，在下一个这样的时间进行PM。讨论了使期望成本率最小的最优k*。此外，当系统由于一定数量的故障、使用、冲击和单元故障而失效时，考虑了四种类似的可选PM模型。

Modified discrete preventive maintenance policies

This article proposes a modified preventive maintenance (PM) policy which may be done only at scheduled times nT (n = 1,2, …): The PM is done at the next such time if and only if the total number of failures exceeds a specified number k. The optimal number k* to minimize the expected cost rate is discussed. Further, four alternative similar PM models are considered, when the system fails due to a certain number of faults, uses, shocks, and unit failures.
