摘　　要：本文给出了制订定时截尾下指数分布产品可靠性抽样检验方案的统计方法.检验统计量是平均寿命倒数的极大似然估计.提出了一种选择截尾时间的方法.利用分布分位数的Cornish-Fisher展开近似地确定了样本量和接收常数.模拟结果表明,本文给出的方法是可行的.This paper gives a statistical method of working out reliability sampling inspection plans for items whose failure times are distributed as exponential distributions. The sampling inspection plan allows Type I censoring. The test statistic is the maximum likelihood estimator of the parameter, the reciprocal of the mean life. An approach for choosing a truncation time is proposed. The sample size and the acceptability constant are approximately determined by using the Cornish-Fisher expansion for quantiles of the distribution. Simulation results show that the method given in this paper is feasible.
