按比例和免费保修策略下费用分析

Cost Analysis of Pro Rata and Free Warranty Policies

本文研究了单部件组成系统的保修策略,提出了一种新的按比例保修和免费保修策略,在假定故障部件不能"修复如新"的条件下,利用几何过程分别考察了顾客和商家关于产品的长期运行平均费用,并给出了它们的明显表达式。

This article considers the warranty policies of a repairable system consisting of one component,involving two kinds of the new warranty policies:the free warranty and the pro rata warranty.Assume that the system after repair is not 'as good as new',by using the geometric process, we examine the longrun expected costs under these policies for both consumer costs and manufacturer costs.Also,the explicit expression of the costs can be found.
