Warranty Cost Analysis for Product Family Based on Fault Tree Mapping

Abstract

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
