A Two Stage Group Acceptance Sampling Plans Based on Truncated Life Tests Using Log-Logistic and Gamma Distributions
Abstract
In this paper, a two stage group acceptance sampling plan is developed for a truncated life test when the lifetime of an item follows Log – Logistic and Gamma distributions. The minimum number of groups required for a given group size and the acceptance number is determined when the consumer’s risk and the test termination time are specified. The operating characteristic values according to various quality levels are obtained. The results are explained with examples.
