| Abstract: | Two statistical methods of working out reliability sampling inspection plans were respectively proposed in this paper under complete sample, the failure times are distributed as exponential distributions. The quality statistic is a monotonous function of a method of moments estimator for the unreliability. An approach of choosing a truncation quality are advanced. The acceptability constant and the sample size were approximately determined by using chi- squares distribution or normal distribution. |
