Acceptance sampling plans based on truncated life test for the generalized Weibull model

Abstract

In this paper, we develop acceptance sampling plan (ASP) when the lifetime experiment is truncated at a pre-assigned time. The minimum sample size required to ensure a specified median life of the experimental unit is provided when the lifetimes of the units follow generalized Weibull distribution which exhibits both monotone and non-monotone failure rates. The operating characteristic values of the sampling plans as well as the producer's risk are also presented. The plan is illustrated through one data analysis.
