Abstract

The purpose of accelerated life test is to promote more failure units of test products in a shorter time, so as to predict the reliability of products under normal conditions based on the failure data collected under accelerated conditions. In view of the right censored data, some statistical optimality is considered. In the framework of generalized linear model, the semi-parametric Cox proportional hazard model is used to obtain the accelerated life test scheme under the U- and D-optimal criteria. From the perspective of prediction variance, the fitting effect is best when the shape parameter 𝛼 is 1.5 in Weibull distribution. The uncertainty of model parameters is evaluated by Monte Carlo technique to verify the feasibility of the test scheme.
