摘要：
To predict the lifetime based on degradation data analysis has been widely studied. The accuracy of lifetime prediction largely depends on whether the degradation model is appropriate or not. For some products, there is a change point in the degradation process, and the entire degradation process can be divided into two phases by the change point. Motivated by an example of resistors, we studied the difference of several modeling approaches with nonlinear gamma and wiener process. The result indicated that modeling the process after the change point obtained more reasonable estimations in the example.
