• ZERO-ONE DOUBLE SAMPLING PLAN FOR TRUNCATED LIFE TEST BASED ON KUMARASWAMY-LOG-LOGISTIC DISTRIBUTION

Abstract

A double acceptance sampling plan for the life test truncated at the pre-assigned time to decide on acceptance or rejection of the submitted lots is considered. This double acceptance sampling plan uses only zero and one failure scheme. The probability model of the lifetime of the product is specified as Kumaraswamy-log-logistic distribution which contains several sub models. The minimum sample sizes of the first and second samples necessary to ensure the specified median life are obtained at the given consumer’s confidence level. The operating characteristic values are analyzed with various ratios of the true median lifetime to the specified lifetime of the product. Numerical examples are provided to explain the utility of sampling plan.
