In this paper, the maintenance optimization problem of multi-component system is considered. It is assumed that the exact cause of system failure might be masked. That is, the exact cause of failure is unknown, and we only know that it belongs to a set called mask set. Both opportunistic perfect preventive maintenance (OPPM) and perfect corrective maintenance are considered. Threshold of OPPM and inter-inspection interval are considered as decision parameters which are optimized using long-run cost rate criteria. The applicability of the proposed maintenance policy is investigated using an illustrative example.

存在屏蔽数据的机会主义完善的预防性维护策略

本文考虑了多组件系统的维护优化问题。假定系统故障的确切原因可能被掩盖。也就是说，失败的确切原因是未知的，我们只知道它属于一个叫做掩码集的集合。机会主义完美预防性维护 (OPPM) 和完美纠正性维护都被考虑。OPPM 阈值和检查间隔被认为是使用长期成本率标准优化的决策参数。使用说明性示例研究了提议的维护策略的适用性。
