A group multiple dependent state sampling plan using truncated life test for the Weibull distribution

Group and conditional sampling methods have been recently developed to apply in industrial environments. Based on the combination of two group and conditional schemes, this article introduces a group multiple dependent state sampling plan for a truncated life test when the lifetime of item follows the Weibull distribution. The proposed plan can be applied when the quality history of process is accessible and a multiple number of items are installed as a group in each tester. The proposed plan has merits which are illustrated via a comparative study over the existing group acceptance sampling plan. Furthermore, a real example is provided.
