摘要: 生产商生产的装备产品整机和整机中由供应商提供的部件,两者保修区间不一致的问题,给生产商带来较高的维保费用,同时影响消费者的使用,给其带来经济损失。为了解决此问题,本文针对装备产品中供应商提供的部件,研究一种灵活延保策略。通过分析部件与整机两者保修区间不一致的几种情形,分别设计供应商的利润函数以及生产商的成本函数,进一步构造以供应商的单位时间利润最大和生产商的单位时间成本最小为目标,以单位时间延保价格、非延保期内单次维修价格和灵活延保策略开始时间与结束时间为决策变量的延保模型,并利用Stackelberg博弈对模型进行优化求解。通过理论分析和数值分析分别得出在不同延保价格与维修价格下和在生产商最大成本预算下的最优延保策略。

Abstract: For equipment products produced by manufacturers, there is a problem of different warranty intervals between a whole equipment machine and its components provided by suppliers. This problem brings high warranty cost to manufacturers, while also affecting consumers’ use and causing their economic losses. To address this issue, this paper investigates a flexible extended warranty strategy for the components provided by suppliers in equipment products. A profit function of suppliers and a cost function of manufacturers are designed respectively through analyzing several cases of different warranty intervals between a whole machine and components. Furthermore, an extended warranty model is proposed, where the objectives are the maximization of supplier’s unit time profit and the minimization of manufacturer’s unit time cost, and the decision variables include the unit time extend warranty price, the single maintenance price during non-extended warranty period, the start and end time of the flexible extended warranty strategy. The model is optimized and solved by Stackelberg game theory. The optimal extended warranty strategies under different prices of extend warranty and maintenance as well as under the maximum cost budget of manufactures are obtained respectively through theoretical and numerical value analysis.
