[2] Mann, N.R. (1972). Design of Over-Stress Life-Tests Experiments when Failure Times have the Two-Parameter

Mathematical Subject Classification: 46N10 Abstract: This paper investigates optimal plans of accelerated life tests (ALT) for exponentially distributed lifetimes under progressive Type I interval censoring with random removals. For dierent combinations of total number of inspections and removal probability, we search for the optimal ALT plans which minimize the asymptotic variance of the estimated mean. Sensitivity analysis on the asymptotic variance of the estimated mean is also conducted to assess the robustness of the results with respect to the given parameters. Finally, suggestions are given to experimenters in designing an ALT under progressive Type I interval censoring with random removals
