Acceptance sampling with rectification when inspection errors are present

In this paper we consider the problem of estimating the number of nonconfor mances remaining in outgoing lots after acceptance sampling with rectificat ion when inspection errors can occur. We show that inspection errors can ha ve a serious biasing effect on the predictor that Greenberg and Stokes (199 2) propose for the number of undetected nonconformances. We develop a new b ias-corrected predictor of this quantity. A simulation study shows that thi s predictor performs well with respect to mean square error under a wide ra nge of scenarios. We also propose a predictor for the number of conforming items rejected.
