—Optimal times of changing stress-level for the simple step-stress plans under the Khamis–Higgins model (an alternative to the Weibull step-stress model) are determined for a wide range of values of the model parameters. The applicability of the “optimal time of changing stress” formula obtained by Khamis–Higgins for a known shape parameter to the case of(More)
