考虑租赁双方的租赁设备多目标预防维护策略

针对当前租赁市场上设备承租方对租赁服务要求提高的市场环境，综合考虑设备出租方和设备承租方的经济利益，建立了考虑租赁双方的租赁设备多目标预防维护模型。首先，基于设备故障状态对设备多维护方式进行决策，考虑设备承租方生产计划与产品质量的需求，利用承租方产品质量需求描述其满意度。其次，建立设备维护的总成本、设备维护活动时长以及设备维护活动对产品质量影响的多目标联合优化模型，最小化设备维护成本的同时，最小化设备总的加工时间，最大化承租方满意度，优化了设备的预防性检测维护周期。最后，通过数值分析验证了这一模型的有效性。联合考虑租赁双方对维护活动的要求更加符合实际的市场需求，降低了设备总维护成本和总加工时间，并且提高了承租方的满意度。

Multi-objective preventive maintenance strategy of leased equipment considering equipment lessors and lessees

Currently, the leaseholder''s demand for leasing services is improved. A multi-objective preventive maintenance model is established by considering the economic interests of the lessors and the lessees. First, based on equipment failure state, the multi-maintenance modes of equipment were decided, the production plan and product quality requirements of equipment lessee were considered, and the product quality requirements of the lessee was used to describe their satisfaction. Then, a multi-objective joint optimization model was proposed to minimize the cost of equipment maintenance and the total processing time of equipment, maximize the satisfaction of the lessee, and optimize the preventive inspection and maintenance cycle. The objective included the total cost of equipment maintenance, the duration of equipment maintenance actions and the impact of equipment maintenance activities on product quality. Finally, the validity of the model was verified by numerical analysis. Joint consideration of the requirements of both parties for maintenance activities was more in line with the actual market demand. The total maintenance cost of equipment and processing time are reduced, and the satisfaction of the lessee is improved.
