Economic Design of SkSP-R Skip-Lot Sampling Plan

Abstract

Skip-lot sampling plans are widely used in industries in order to reduce sampling costs and inspection efforts when products have a good quality history. This type of skip-lot sampling plan is economically advantageous and useful to minimize the cost of the inspection particularly with costly and destructive testing. Recently, a new type of skip-lot sampling plan called SkSP-R was developed. In this paper, an economic design of the SkSP-R plan is proposed for both destructive and non-destructive testing by considering various cost items in order to optimize the plan.
