Abstract:
|
A number of authors have considered the procedure of on-line process control in which every m-th item produced is inspected. The process continues if the inspected item conforms to specifications. If the inspected item fails to conform, then the process is stopped, examined, and adjusted as necessary. More recently, a modification has been considered which has incorporated the possibility of misclassifying items when they are inspected and different schemes have been suggested for dealing with this. The item which is inspected is typically now subjected to repeated independent classifications which may classify the item differently. Some rule is used to determine whether the item should be ultimately judged as conforming or nonconforming. We review this literature and propose and study new schemes for ultimately judging the item.
