Abstract
A simple step-stress accelerated life testing plan is considered when the failure times in each level of stress are geometrically distributed under Type-I censoring. The problem of choosing the optimal plan is investigated using the asymptotic variance-optimality as well as determinant-optimality and probability-optimality criteria. To illustrate the results of the paper, an example is presented and a sensitivity analysis is performed. A simulation study is also performed to investigate the robustness of the criteria with respect to estimation error of the parameters. Eventually, some conclusions are presented.
