针对部分恢复预防性维护行为（不完全预防性维护行为）和变工况联合作用下的系统，提出了两种部件级控制极限预防性维护策略，并研究了所提策略的性质.扩展比例风险模型（EPHM）被用来模拟系统的故障可能性的影响，这两个因素。利用真实的寿命和运行条件数据以及不完善PM行为和维护持续时间的典型表征，进行了几个数值实验用于策略属性分析。实验结果表明，考虑这两个因素时，他们确实存在的必要性，表征的联合效应的两个因素对性能的优化PM政策，并探讨了随时间变化的操作条件的加载顺序对性能的优化PM政策。所提出的政策扩展PM优化技术的适用性。
This paper develops two component-level control-limit preventive maintenance (PM) policies for systems subject to the joint effect of partial recovery PM acts (imperfect PM acts) and variable operational conditions, and investigates the properties of the proposed policies. The extended proportional hazards model (EPHM) is used to model the system failure likelihood influenced by both factors. Several numerical experiments are conducted for policy property analysis, using real lifetime and operational condition data and typical characterization of imperfect PM acts and maintenance durations. The experimental results demonstrate the necessity of considering both factors when they do exist, characterize the joint effect of the two factors on the performance of an optimized PM policy, and explore the influence of the loading sequence of time-varying operational conditions on the performance of an optimized PM policy. The proposed policies extend the applicability of PM optimization techniques.
