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 (R_s). In this present paper, inspection strategy based on sample inspection reliability is considered, together with some factors influent to R_s is analyzed such as sample size, producer risk and consumer risk, acceptable quality level (AQL), rejectable quality level (RQL).
