Abstract

The exploration of component states for optimizing maintenance schedules in complex systems has garnered significant interest from researchers. However, current literature usually overlooks the critical aspects of system flexibility and reconfigurability. Judicious implementation of system reconfiguration can effectively mitigate system downtime and enhance production continuity. This study proposes a dynamic condition-based maintenance policy considering reconfiguration for reconfigurable systems. A double-layer decision rule was constructed for the devices and systems. To achieve the best overall maintenance effect of the system, the remaining useful life probability distribution and recommended maintenance time of each device were used to optimize the concurrent maintenance time window of the devices and determine whether to reconfigure them. A comprehensive maintenance efficiency index was introduced that simultaneously considered the maintenance cost rate, reliability, and availability of the system to characterize the overall maintenance effect. The reconfiguration cost was included in the maintenance cost. The proposed policy was tested through numerical experiments and compared with different-level policies. The results show that the proposed policy can significantly reduce the downtime and maintenance costs and improve the overall system reliability and availability.

可重构多设备系统的基于状态的维护策略

为优化复杂系统的维护计划而对组件状态进行的探索引起了研究人员的极大兴趣。然而，目前的文献通常忽略了系统灵活性和可重构性这两个关键方面。明智地实施系统重新配置可以有效减少系统停机时间，提高生产连续性。本研究针对可重构系统提出了一种考虑到重构的基于状态的动态维护策略。针对设备和系统构建了双层决策规则。为了实现系统的最佳整体维护效果，利用各设备的剩余使用寿命概率分布和推荐维护时间来优化设备的并发维护时间窗口，并确定是否对其进行重新配置。引入综合维护效率指数，同时考虑系统的维护成本率、可靠性和可用性，以表征整体维护效果。重新配置成本包含在维护成本中。通过数值实验对提出的策略进行了测试，并与不同级别的策略进行了比较。结果表明，建议的策略可以显著减少停机时间和维护成本，并提高系统的整体可靠性和可用性。
