基于不同租期下的预防性维修优化策略

针对租赁市场的实际情况,提出了一种既考虑租期不同又考虑维修服务质量的多设备租赁的预防性维修策略;策略综合考虑了惩防成本、预防维修、小修、故障率阈值以及维修服务质量等因素对利润的影响,以出租方利润最大化为目标的预防性维修策略,优化了故障率阈值,并利用遗传算法共同优化了修复程度和不同租期下的维修次数;实例证明了模型的可行性,也为企业的设备维修管理提供了一种新的建模与决策思路。

Optimization Strategy of Preventive Maintenance Based on Different Lease Periods

In view of the actual situation of the leasing market, a preventive maintenance strategy for multi-equipment leasing considering the different lease periods and the quality of maintenance service is proposed.In this strategy, the influence of the cost of punishment, preventive maintenance, minor repair, failure rate threshold and maintenance service quality on the profit is considered comprehensively.The preventive maintenance strategy aiming at maximizing the profit of the lessor is optimized, and the failure rate threshold is optimized.Genetic algorithm is used to optimize repair degree and maintenance times under different lease periods.The example proves the feasibility of this model and provides a new way of modeling and decision-making for enterprise equipment maintenance management.
