Abstract
In this paper, repetitive types of group acceptance sampling plans are proposed when the lifetime of the product follows the Weibull distribution or the generalized exponential distribution. Quality characteristics are considered in terms of percentile lifetimes. Plan parameters are found by satisfying the producer's risk and consumer's risk at the same time while minimizing the average sample number. Extensive tables are given for practical use. Two examples are given to illustrate the proposed plan in real world.
