MIL-STD-105 was a United States defense standard that provided procedures and tables for sampling by attributes based on Walter A. Shewhart, Harry Romig, and Harold F. Dodge sampling inspection theories and mathematical formulas. Widely adopted outside of military procurement applications.
A single sampling plan for attributes is a statistical method by which the lot is accepted or rejected on the basis of one sample. [4] Suppose that we have a lot of sizes M {\displaystyle M} ; a random sample of size N < M {\displaystyle N<M} is selected from the lot; and an acceptance number B {\displaystyle B} is determined.
Re-shipment acceptance sampling, involving inspection, and acceptance testing, may be agreed upon between a buyer, a supplier, and a bank, and it can be used to initiate payment under a letter of credit. A PSI can be performed at different stages before shipment, such as checking the total amount of goods and packing, controlling the quality or ...

This plan requires the knowledge of the statistical model (e.g. normal distribution). The historical evolution of this technique dates back to the seminal work of W. Allen Wallis (1943). The purpose of a plan for variables is to assess whether the process is operating far enough from the specification limit. Plans for variables may produce a ...
Lot quality assurance sampling (LQAS) is a random sampling methodology, originally developed in the 1920s [1] as a method of quality control in industrial production. Compared to similar sampling techniques like stratified and cluster sampling , LQAS provides less information but often requires substantially smaller sample sizes.
