Abstract

Facing the uncertainty in transaction of two-dimensional extended warranty, a flexible pricing model is presented considering imperfect preventive maintenance combined with the degradation characteristics of item. The measure of two-dimensional preventive maintenance is carried out based on specified age interval or usage interval, the effect of imperfect preventive maintenance is described by age reduction model. The extended warranty cost is modeled from the perspective of manufacturer and customer, the method of gridding search is employed to optimize the maintenance strategy under different cases. Moreover, customized extended warranty price and warranty services are proposed on the basis of consumer usage rates. The results demonstrate that it is helpful to maximize the benefit of vendor by providing customized warranty strategy, the implementation of preventive maintenance during the whole warranty period can effectively reduce warranty cost for both sides.

摘要

针对延长质保合同交易的不确定性，结合产品的性能退化规律，提出了考虑不完全预防性维修的二维延长质保定价模型。同时考虑时间间隔和使用度间隔对产品实施二维预防性维修措施，采用虚拟年龄法描述预防性维修的实施效果。分别从制造商和顾客的角度完成延长质保成本建模，在不同的预防性维修方案下，采用网格搜索法优化预防性维修策略以及延长质保价格，根据顾客使用率的差异性提出定制化延长质保定价方案。案例研究表明：根据使用率不同，通过为顾客提供定制化的延保价格和维修策略，有助于制造商利益的最大化；在整个质保期内实施预防性维修措施，可以有效减少双方的质保费用。
