Condition-based maintenance (CBM) is receiving increasing attention in various engineering systems because of its effectiveness. This paper formulates a new CBM optimization problem for continuously monitored degrading systems considering imperfect maintenance actions. In terms of maintenance actions, in practice, they scarcely restore the system to an as-good-as new state due to residual damage. According to up-to-data researches, imperfect maintenance actions are likely to speed up the degradation process. Regarding the developed CBM optimization strategy, it can balance the maintenance cost and the availability by the searching the optimal preventive maintenance threshold. The maximum number of maintenance is also considered, which is regarded as an availability constraint in the CBM optimization problem. A numerical example is introduced, and experimental results can demonstrate the novelty, feasibility and flexibility of the proposed CBM optimization strategy.

不完善维护操作下连续监测退化系统的基于状态的维护优化

基于状态的维护 (CBM) 因其有效性而在各种工程系统中受到越来越多的关注。本文针对考虑不完善维护操作的连续监测退化系统制定了一个新的 CBM 优化问题。在维护操作方面，实际上，由于残留损坏，它们几乎不会将系统恢复到与新状态一样好的状态。根据最新数据研究，不完善的维护措施可能会加速退化过程。对于开发的煤层气优化策略，它可以通过搜索最优预防性维护阈值来平衡维护成本和可用性。还考虑了最大维修次数，这被视为煤层气优化问题中的可用性约束。介绍一个数值例子，
