Optimum Design for Type-I Step-Stress Accelerated Life Tests of Two-parameter Weibull Distributions

摘要：

In the paper, we focus on k-step step-stress accelerated life tests with censored sample from twoparameter Weibull distributions based on the tampered failure rate (TFR) model. We get the optimum design for the TFR model using the likelihood function and Fisher information matrix. Finally, we illustrate the feasibility of this method through two examples.
