分别在威布尔分布和对数正态分布场合,通过Monte-Carlo模拟比较了步降试验和步加试验的效率,得到步降试验的效率优于步加试验的条件.
This article compares the efficiency of the step-down-stress ALT and the step-down-stress ALT on the Weibull distribution and the lognormal distribution occasions, respectively by Monte-Carlo simulation. Thus we obtain a condition on which the step-down-stress ALT is better than the step-down-stress ALT.
