Acceptance Sampling Plans from Truncated Life Tests Based on the Log-Logistic Distributions for Percentiles

Abstract

In this article, acceptance sampling plans are developed for the log-logistic distribution percentiles when the life test is truncated at a pre-specified time. The minimum sample size necessary to ensure the specified life percentile is obtained under a given customer's risk. The operating characteristic values (and curves) of the sampling plans as well as the producer's risk are presented. Two examples with real data sets are also given as illustration.
