Abstract
A skip-lot sampling program is described consisting of three states:
(1) | lot-by-lot inspection | ||||
(2) | skip-lot inspection | ||||
(3) | skip-lot interruption. |
The proposed switching rules are based on controlling three characteristics:
(1) | the number of lots inspected during the lot-by-lot state until qualification | ||||
(2) | the number of lots inspected during the skip-lot state until detection of a change in quality | ||||
(3) | the probability of resuming skip-lot inspection from the interruption state. |
The program has been submitted as a proposed ANSI standard to the ASQC Statistical Standards Committee and currently is in the Draft 2 stage of acceptance.
