Truncated Life Test Sampling Plan under Log-Logistic Model

M.Gomathi, Dr. S. Muthulakshmi

Skip Lot acceptance sampling plan is proposed for the truncated life test based on product quality following log-logistic distribution. For the proposed plan the minimum sample size 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. The minimum ratios of the true population median life to the specified median life are also obtained at the specified producer’s risk. Selection and application of sampling plan is illustrated with a numerical example.
