Abstract
This article considered the problem of developing double acceptance sampling plans (DASP) in terms of truncated life tests considering that the lifetime of the lot follows the two-parameter Xgamma (TPXG) distribution. The mean of the TPXG distribution is utilized as the quality parameter. The smallest sample sizes of the first and second samples desired to emphasize the identified mean life are obtained at a given consumer's confidence (CC) level. The corresponding operating characteristic (OC) values for several quality levels are found as well as the smallest ratios of the mean life to the indicated life are presented. Also, the producers risk (PR) is studied. Numerical results and examples are analyzed for illustration.
