摘要

Most products are affected by multiple stresses simultaneously, so it is necessary to study the optimal method for accelerated degradation testing (ADT) with multiple stresses. This method is proposed for constant stress ADT (CSADT). First, uniform orthogonal test theory is used to determine the combined mode of different stresses. Then stochastic process is used to model the perform degradation of products. Under the constraint of the total experimental cost, the optimumproblem is established with the objective that minimizing the asymptotic variance of the estimation of the reliability of the pth quantile of product’s lifetime under use condition. Optimal test variables are given, including: levels of each stress, total sample size and testing time, and sample size and testing time at each stress combination. Finally, simulation examples are presented to illustrate the proposed method.
