Abstract | This article considers the determination of optimum settings of design parameters of a life testing experiment under progressive censoring scheme by minimizing the total cost associated with the experiment. It is shown that the proposed cost function is scale invariant for location-scale and log-location-scale families of distribution. This is a discrete optimization problem, in which the optimum solution cannot be obtained analytically. However, a metaheuristic algorithm based on variable neighborhood search approach is proposed to obtain optimum censoring scheme. Finally, a well-planned sensitivity analysis is done in order to study the effect of mis-specification of parameter values and cost components on the optimum solution.
