摘要
针对二手设备的维护优化问题,从租赁企业的视角出发,提出考虑学习效应的二手设备维护优化策略.该策略考虑学习效应对预防维护成本的影响,建立以租赁企业期望总成本最小化为目标的二手设备维护策略模型,并给出了模型优化的相关算法.算例研究表明:考虑学习效应的优化策略的期望总成本最优值低于未考虑学习效应优化策略下的期望总成本最优值,并对参数的灵敏度进行了分析,文中结论可为租赁企业进行设备维护决策提供理论依据.
Abstract
From the perspective of leasing company,this paper studies the optimal mainte-nance strategy for second-hand equipment considering learning effect.Aiming at minimizing the expected total cost for leasing company,this optimal strategy establishes a maintenance model for second-hand equipment as well as providing the related algorithms,with the consid-eration of learning effect's impact on preventive maintenance costs.Based on numerical study,it is shown that the optimal expected total cost of the strategy is lower than that without considering learning effect.The sensitivity of parameters in the model has also been analyzed subsequently.The optimal strategy provided in this paper is able to help leasing company determine equipment maintenance policy with solid theoretical basis.
