Selection Of Three Stage Chain Sampling Plan Of Type Chsp (0, 1, 2) Indexed With Aql And Aoql

摘要

This article provides a new procedure for selection of three-stage Chain sampling plan of type ChSP (0, 1, 2) indexed with AQL and AOQL. Tables and Procedures are also provided for the selection of plan with AQL and AOQL. Illustrations are also provided for the ready-made shop floor situations. Soundararajan and Raju (1984) outlines the structure of the generalized family of Three-Stage chain Sampling Plan, extending the concepts proposed by Dodge (1955) and Dodge and Stephens (1966). Expressions are also derived for operating characteristic (OC) curves for several sets of three-stage Chain Sampling Plans, with cumulative acceptance numbers of (c_1, c_2,c_3) = (0, 1,2), (0, 1, 3), (0, 2, 3), (1, 2, 3), etc., respectively. Dodge (1955) has considered only acceptance numbers of 0 and 1 with a more limited rule of cumulation. Soundararajan and Raju (1984) has also given the OC curves for a number of plans and comparisons are made with some single sampling plan and two-stage chain Sampling Plans.
