Sampling Plan Adjustment for Inspection Error and Skip-Lot Plan

Summary: (This paper has been selected for presentation at the Journal of Quality Technology session of the 26th Annual Fall Technical Conference of the Chemical Division of the American Society for Quality Control and the Section of Physical and Engineering Sciences in Atlantic City, New Jersey, October 21-22, 1982.)Inspection errors can have a severe impact on an attributes single-sampling plan for lot acceptance due to misclassification of units as defectives or nondefectives. However, with estimates of the errors, the plan can be adjusted to preserve the desired operating characteristic curve or average outgoing quality limit (AOQL). Allowance is made for a skip-lot plan and a sampling plan for rejected lots that have been screened 100 percent.
