Time Truncated Modified Group Chain Sampling Plans for Marshall Olkin Extended Lomax Distribution

Abstract

Time truncated life test and group sampling technique are introduced for time saving purpose by limiting time of inspection and providing a platform for multiple inspection respectively. The issue of rapid change in operating characteristics faced by sampling plan with zero acceptance number was fixed by chain sampling plan which considers preceding lots in the acceptance criteria. Modified chain sampling reworks chain sampling by providing tighter inspection in order to give more protection to consumer. In this article, the acceptance sampling plans for attributes called Modified Group Chain Sampling Plan (MGChSP) for Marshall Olkin Extended Lomax (MOEL) distribution is developed by combining group sampling and modified chain sampling technique. The performance of MGChSP is measured by obtaining minimum number of groups and probability of lot acceptance following selected values of design parameters.
