Abstract

The purpose of Skip-lot sampling is to reduce the Average Sample Number (ASN) and Average Total Inspection (ATI)
as well as inspection costs. The Skip-lot concept is economically advantageous to make decision on the submitted lot. This
paper presents the comparison of skip lot sampling plan SkSP-2 and SkSP-V in terms of Probability Accepting, (Pa), Average
Outgoing Quality (AOQ), ASN, ATI and also cost reduction. The results indicated that SkSP-2 and SkSP-V were not significant
different on the Pa and AOQ. However, SkSP-V gave lowest cost significantly both from ASN and ATI. This property shows
the advantage of SkSP-V for the lowest cost inspection but SkSP-2 for easier implementation because of the smaller parameters in actual operation.
