Abstract Existing sensitivity analysis of accelerated degradation tests design is mainly based on single factor analysis method. The situation where multiple parameters fluctuate simultaneously is not considered. Besides, these researches only aim at guaranteeing that the optimal results do not have large fluctuations with change of model parameters, but the different impact of parameters to the optimal results has not been discussed. To solve these problems, a novel sensitivity analysis procedure is constructed via a normalized orthogonal design method, which can illustrate the different impact of model parameters to the optimal results when the parameters change simultaneously.

A case study is presented accordingly. an optimal constant-stress accelerated degradation test design for GaAs laser is given to illustrate the implementation procedure. The analyzing results demonstrate the rationality and effectiveness of the proposed method.
