Tables for Determining Expected Cost Per Unit under MIL-STD-105D Single Sampling Schemes

AIIE Transactions, 6, pp. 135-142. When a MIL-STD-IOSD sampling scheme is used for a long period, some lots will be subjected to normal, some to reduced, and some to tightened inspection. This paper provides for several single sampling plans and various quality levels,'the expected fraction of lots rejected,the expected sample size per lot, and the expected number of lots to be processed before sampling inspection must be discontinued. Eq.uations are given to calculate the long term cost of sampling inspection using these expected values and appropriate cost parameters.
