基于费效分析的装备延伸保修购买决策

Research on Equipment Extended Warranty Purchase Decision-Making Based on Cost-Effectiveness Analysis

保修机制是部队引入承制方装备维修力量的重要途径,延伸保修对装备的寿命周期费用以及承制方保修费用有很大影响。针对军方延伸保修购买决策问题,在对维修策略分析的基础上,综合考虑装备维修费用和可用度,建立了延伸保修购买决策相关模型,结合装备承制方保修成本及军方装备维修费用——效能分析,得到了在不同价格区间内延伸保修购买决策,并给出了特定条件下存在的双赢延伸保修价格区间,最后通过实例验证了模型的有效性。

Warranty is an important way to introduce manufacture’s maintenance resource into the army,and the extended warranty has significant effect on manufacturer’s warranty cost and equipment’ s Life Cycle Cost (LCC). In order to make a decision for the problem whether purchasing the extended warranty,in this paper a mathematical decision model to obtain the extended warranty purchase decision-making strategy under different price interval based on the analysis of extended warranty policy by balanced the benefit of manufacturer and military is developed. The model also allows looking if there is zone of compromise yielding a win-win relationship with respect to the cost and availability of the product. At last,the model proved to be practical by the case study.
