A Hybrid Group Acceptance Sampling Plan for Lifetimes Based on Gamma, Exponentiated Log – Logistic and Marshall – Olkin extended exponential Distributions

In this paper we have developed a hybrid group acceptance sampling plan for a truncated life test when the lifetime of an item follows gamma distribution, exponentiated log – logistic distribution and Marshall – Olkin extended exponential distribution. The minimum number of testers and acceptance number are determined when the consumer’s risk and the test termination time and group size are specified. The operating characteristic values according to various quality levels are also obtained
