摘要 针对二手产品的维修问题,给出了二手产品生命周期的定义,提出了考虑更新延长两阶段保修的维修策略模型.该策略综合考虑了产品的年龄变化、延保折扣、小修和生产损失费用等因素,从顾客的角度出发,建立以顾客期望总费用率最小化为目标的免费更换保修和按比例更换保修两种策略模型,并给出模型最优化的相关理论证明.算例研究验证了模型的有效性,并对参数的灵敏度进行了分析,文中结论可为顾客进行产品维修计划提供决策依据. This paper presents a model for second-hand products with an extended two-phase warranty while the definition of life cycle is reexamined.The factors such as product’s age changed,extended warranty discount,minimal repair and lost production costs are taken into consideration in this model.It aims to fulfill the custom-ers’expectation of minimizing the total cost rate per unit.Accordingly,free replacement/repair warranty policy and pro-rata replacement warranty policy are offered.As a proof of the model’s optimal value,related theoreti-cal explanation is provided.Above all,a case study,including the analysis for the sensitivity of the parameters,verifies the validity of the model.The conclusion can provide decision basis for customers with product mainte-nance plans.
