A new approach of chain sampling inspection plan

TL;DR

This paper introduces a modified chain group acceptance sampling plan that reduces sample sizes by effectively chaining past lot results, offering a more efficient alternative to traditional sampling plans.

Contribution

It proposes a new chaining approach called the modified chain group acceptance sampling plan, which requires smaller samples than existing methods.

Findings

The proposed plan reduces sample sizes compared to traditional methods.

Comparison studies show the efficiency of the new approach.

An illustrative example demonstrates practical application.

Abstract

To develop decision rules regarding acceptance or rejection of production lots based on sample data is the purpose of acceptance sampling inspection plan. Dependent sampling procedures cumulate results from several preceding production lots when testing is expensive or destructive. This chaining of past lots reduce the sizes of the required samples, essential for acceptance or rejection of production lots. In this article, a new approach for chaining the past lot(s) results proposed, named as modified chain group acceptance sampling inspection plan, requires a smaller sample size than the commonly used sampling inspection plan, such as group acceptance sampling inspection plan and single acceptance sampling inspection plan. A comparison study has been done between the proposed and group acceptance sampling inspection plan as well as single acceptance sampling inspection plan. A example has been given to illustrate the proposed plan in a good manner.
