摘 要:针对租赁设备的特殊性,提出等周期和变周期策略相结合的多阶段预防性维护策略。该策略将租赁期划分为多个维护阶段,每阶段内进行等周期维护,同时各阶段间的维护周期逐渐缩短。为了适应租赁设备新旧兼备的特点,该策略以虚拟年龄的固定比例作为衡量标准。综合考虑小修、惩罚等多种成本,建立以出租方维护成本最小化为目标的多阶段预防性维护模型。最后的数值分析将其与等周期策略进行了对比分析,验证了其有效性。Aiming at the particularity of leased equipment, a multi-phase preventive maintenance strategy was pro posed by combining equal-cycle strategy with the variable-cycle strategy. Under this policy, the lease period was di vided into multiple phases while equal-cycle maintenance was provided in each of them with the cycle gradually get ting shortened. To adapt the leased equipment's features of both new and old, the fixed proportion of virtual age was taken as the benchmark. By considering Corrective Maintenance(CM) cost, Preventive Maintenance (PM) cost and penalty cost comprehensively, the multi-phases PM model aiming at the maintenance costs minimum of lessor was constructed. The numerical analysis was used and compared with other strategies to validate the effectiveness of pro posed strategy.
