摘要
科学合理租赁设备预防性维修策略对租赁商来说可以降低设备维修成本和延长设备生命周期,对承租企业来说可以拥有工作状态良好的设备。文章假设对租赁设备进行不定期的预防性维修且每次进行相同的维修强度,租赁商以利润最大化为目标,联合优化预防性维修的阀值、维修强度和维修次数,据此通过算例分析故障率和租期分别对维修次数、预防性维修较单纯故障维修的节约成本及节约成本占单纯故障维修成本比重的影响。
The scientific and rational preventive maintenance strategy of leasing equipments can reduce maintenance cost and extend life cycle of equipments for the leasor, and can also provide the leasee with well-conditioned equipments. In this paper, it is assumed that the preventive maintenance is ir- regular, but has same maintenance strength. The threshold, strength and frequency of the preventive maintenance are jointly optimized to maximize the profit of the leasor. Finally, the numerical examples are conducted to analyze the impact of failure rate and tenancy on the frequency of the preventive ma- intenance, the saving cost and the ratio of the saving cost to the pure corrective maintenance.
