Selection of the Double Sampling Plan Through Quality Regions

Abstract

In this article we have developed new method for designing sampling plans based on range of quality instead of pointwise description of quality by invoking a quality regions approach. Maximum allowable percent defective (MAPD) is also considered for the selection of parameters for a double sampling plan. New quality descriptors called operating ratios are introduced to design the sampling plan, and related information is provided. Illustrations are provided for ready-made use of the tables in shop-floor situations.
