报告内容简介：:

In this talk, we propose a framework to analyze accelerated degradation testing (ADT) data in the presence of inspection effects. Motivated by a real dataset from the electric industry, we study two types of effects induced by inspections. After each inspection, the system degradation level instantaneously reduces by a random value. Meanwhile, the degrading rate is elevated afterwards. Considering the absence of observations due to practical reasons, we employ the expectation –maximization (EM) algorithm to analytically estimate the unknown parameters in a stepwise Wiener degradation process with covariates.
