  • In constant stress accelerated degradation testing (CSADT)scheme, there are four variables: stress levels, interval of performance inspection, sample size and number of inspection at each stress level need to be determined. However, the issue about how to optimize stress levels is seldom discussed. For optimizing the four variables comprehensively a method was proposed. First stochastic process was used to describe a typical CSADT problem. Next, under the constraint that the total experimental cost does not exceed a predetermined budget, the objective is to minimize the asymptotic variance of the estimation of the reliability of the pth quantile of product-s lifetime under use condition. The optimal plan can give the four variables mentioned above. Then a simulation example was presented to illustrate this method. Finally, sensitivity analyses of optimal plans to misspecifications illuminates that the optimal plan is quiet robust for a moderate departure from the assumed value of parameters.
