BEST COMPROMISE TEST PLANS FOR WEIBULL-DISTRIBUTIONS WITH DIFFERENT CENSORING TIMES

This paper presents the best compromise three-level constant stress ac celerated life test plans for Weibull distributions with different cen soring times. The best compromise test plans choose the stress levels, test units allocated to each stress and censoring times to simultaneo usly minimize the asymptotic variance of the MLE of the mean log life at design stress and total running time. This paper also compares the test plans with existing three-level test plans and concludes that the best compromise test plans (1) have less asymptotic variances, (2) ar e more robust and (3) are more cost-effective, than the existing three -level test plans.
