Acceptance Sampling Plans Based on Truncated Life Tests in the Inverse-Gamma Model

In this article, acceptance sampling plans are suggested for the life test that is truncated at a preassigned time. The life time of the test units are assumed to follow the inverse-gamma distribution. The minimum sample sizes necessary to ensure the specified mean life is obtained. The operating characteristic function values of the proposed sampling plans and the producer's risk are provieded. Some tables are given and the results are illustrated by numerical examples
