Average Run Length and the OC Curve of Sampling Plans

Summary: [This abstract is based on the author's abstract.]The distinction between Type A and Type B sampling plans for individual lots and processes is expanded. Binomial distribution is introduced as a Poisson-type finite analog to the hypergeometric distribution in the construction of appropriate Type A OC curves for defects. It is also noted that average run length has not been utilized as a characterizing feature in the evaluation of Type B sampling plans.
