Abstract
This paper proposes a new sampling strategy by considering the concept of resampling with switching rule based on the process yield index. The proposed plan is designed involving a flexible critical region and two inspection policies for deciding on the submitted lot. The computation result shows that such design can lessen the average sample number (ASN) for inspection under the same quality requirements and tolerable risks. Besides, the proposed method provides a better shape of operating characteristic (OC) curve which guarantees better performance on its discriminatory power. The plan parameters of the proposed method with selected conditions are provided as well for quick reference.
