Abstract: The optimal times of changing stress level for simple stress plans under a cumulative exposure model using the Lomax distribution are determined for a wide range of values of the model parameters. The scale parameter of the Lomax failure time distribution at constant levels is assumed to be a log linear function of the stress level. The optimum test plan is obtained by minimizing with respect to the change time, the asymptotic variance (AV) of the maximum likelihood estimator (MLE) of… CONTINUE READING
