Minimum average fraction inspected for TCSP-1 plan

This paper presents the calculation of the average outgoing quality limit (AOQL) for the tightened single-level continuous sampling plan (TCSP-1 plan) based on a numerical method. A solution procedure is developed to find the parameters (i, f, k) that will meet the AOQL requirement, while also minimizing the average fraction inspected (AFI) for the TCSP-1 plan when the process average pmacron(> AOQL) is known.
