摘要/Abstract

摘要： 针对当前制造企业的产品通常以产品族而不是单一产品的形式存在的现实，对现有的基于单一产品的保证成本计算模型进行了改进，并指出产品族保证成本计算取决于配置产品的元件的可靠性。通过逆向搜索的方法，元件可靠性可以根据故障树模型向BOM模型映射得到。作者通过一个笔记本电脑的案例说明文中方法的操作过程，并比较了企业采用FRW和PRW两种策略时保证成本的差异。

关键词: 保证成本, 产品族, 故障树, 逆向搜索

Abstract: Currently, product warranty cost is calculated based on individual products. However, today, warranty is always offered with respect to product family rather than individual products. Thus, new method is necessary for product warranty cost calculation. In this paper, the existing models for individual products are modified to adapt to product family. In the new model, module reliability is defined through the mapping from the fault tree model to the bill of material (BOM) model by using inverse search. The warranty cost calculation for laptop computer is used to show the application of the proposed method. The results are compared with the existing method such as free replacement warranty(FRW)and prorata warranty(PRW). It shows that the proposed method is effective.

Key words: warranty cost, product family, fault tree, inverse search
