The continuing evolution of the military standard 105d sampling system

Military Standard 105D is the most widely used set of acceptance sampling plans in the world. This paper reviews the early development of the standard and points out the many contributions made by Bell System researchers, such as H. F. Dodge. The paper also reviews recent analyses and indicates areas where the special structure suggested by Dodge, and adopted in the standard, has been extremely valuable. Finally, the paper identifies many questions related to the standard that are still open for investigation.
