Quantification of Uncertainty of Warranty Claims

This chapter reviews the definition of warranty, introduces its different types, discusses possible causes of warranty claims, and then provides an introductory overview of the approaches to modelling warranty claims. When only warranty claim related data are available, statistical models are suggested to model the frequency of warranty claims. This approach is referred to as the black-box approach in the chapter. When the physical structure and the failure mechanism are known, both statistical models and physical models can be applied in modelling the frequency of warranty claims. This approach is referred to as the white-box approach. The chapter suggests that models that can reflect the real-world claim patterns should be the focus studied by researchers in the future.
