Skip-Lot Sampling Plans

Summary: This article presents a system of skip-lot sampling plans for lot-inspection designated as type SkSP-2, where provision is made for skipping inspection of some of the lots when the quality of the submitted product is good. The operating characteristic properties are presented, as well as the plan's Average Sample Number (ASN), its response-to-change characteristics, and a measure of the Average Outgoing Quality Limit (AOQL) in terms of "nonconforming" lots.
