Abstract: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.
Keywords:Exponential distribution   sampling inspection plan   maximum likelihood estimator   Cornish-Fisher expansion.
