Modified Tables For The Selection Of Qss-1 Quick Switching-System For A Given (Aql, Lql)

This paper presents a set of new tables and procedures for the selection of the following three types of Quick Switching (QS) systems for a given Acceptable Quality Level (AQL), Limiting Quality Level (LQL), producer's risk and consumer's risk. (1) A Single sampling QS system with equal sample sizes but with different acceptance numbers. (2) A Single sampling QS system with two different sample sizes but with same acceptance number and (3) A QS system with double sampling normal inspection and single sampling tightened inspection.The third type of QS system is the one newly presented in this paper. The tables provide unique plans for a given set of conditions as well as providing a smaller sample size or a smaller sum of Average Sample Numbers (ASN) at the AQL and LQL.
