On Inspection Strategy Based on Sample Inspection Reliability
As we all known, for a certain product, inspection reliability for the product can be considered and calculated by a famous reliability index as POD (Probability of Detection). While, for a batch of product, Stat. character should be added into POD because one-by-one inspection always is not economic, and POD without any consideration of Stat. character is not used directly for inspection reliability of a batch of product. So, inspection reliability for a batch of products can be considered and divided into reliability of inspecting objective (could be defined as POD) and reliability induced by sample inspection (Rs). In this present paper, inspection strategy based on sample inspection reliability is considered, together with some factors influent to Rs is analyzed such as sample size, producer risk and consumer risk, acceptable quality level (AQL), rejectable quality level (RQL).
