Abstract

In this article, a group acceptance sampling plan is developed based on truncated lifetimes when the lifetime of an item follows a half normal distribution. For a given group size, the minimum number of groups and the acceptance number required are determined for specified consumer's risk and the test termination time. The values of operating characteristic function for various quality levels are calculated and the minimum ratios of the true average life to the specified life at given producer's risk are obtained. The results are illustrated by examples.
