Performance Comparison of Group Chain Sampling Plan and Modified Group Chain Sampling Plan Based on Mean Product Lifetime for Rayleigh Distribution
The performance of a sampling plan from group sampling family is measured by its minimum number of groups and probability of lot acceptance. Basically, once the minimum number of groups is determined, the corresponding probability of acceptance can be obtained for various sets of design parameters. This article compares the performance of two acceptance sampling plans namely group chain sampling plan (GChSP) and modified group chain sampling plan (MGChSP-1) based on the mean product lifetime for Rayleigh distribution. GChSP and MGShSP were developed based on the operating procedure in both chain sampling plan (1955) and group sampling plan (2009). The findings proved that the MGChSP performed better than the GChSP.
