Time Truncated Group Acceptance Sampling Plans for Generalized Exponential Distribution

Abstract

Two group acceptance sampling plans are considered for a two-parameter generalized exponential distribution when the life-test is truncated at a pre-specified time. It is assumed that the shape parameter of the generalized exponential distribution is known. The design parameters such as the number of groups and the acceptance number are obtained by satisfying the producer's and consumer's risks at the specified quality levels in terms of medians, under the assumption that the termination time and the number of items in each group are pre-fixed. Examples are provided for illustrative purposes. Copyright © 2011 by ASTM International.
