Abstract

The main goal of this study is to propose a chain Group Acceptance Sampling Plan (GASP) when the life time of a product follows the Pareto distribution of the 2nd kind. The design parameters such as the minimum group size and operating characteristic values are obtained by satisfying the producer’s and consumer’s risks at the specified quality level, acceptance number and the test termination time.A classical example is considered in order to compare the proposed plan with some existing plans.

Highlights

  • Acceptance sampling is a useful technique for quality assurance assertion

  • If the failed products are less than the specified acceptance number, the same submitted lot will be acceptable for consumer use

  • In established chain sampling plans, a single product is tested but in practice, testers are accessible that can contain more than one product

Summary

Introduction

Acceptance sampling is a useful technique for quality assurance assertion. It is recommended when sample size is essential towards excessive testing for product quality. When an acceptance sampling plan is considered, the lot is either accepted or rejected along with affiliated producer’s and consumer’s risks. If the failed products are less than the specified acceptance number, the same submitted lot will be acceptable for consumer use. The criteria for accepting and rejecting the submitted lot depend on the information of the inspection of immediately preceding samples. The use of chain sampling plan is usually suggested when an extremely high quality product is needed. In established chain sampling plans, a single product is tested but in practice, testers are accessible that can contain more than one product
