Abstract:
|
We consider a process control model in which the quality of the inspected items is classified as being in one of three states rather than simply conforming or nonconforming. Items may be judged to be superior, acceptable, or nonconforming and the percentages associated with these categories will differ based on whether the process is in control or out of control. There is, however, a possibility of misclassifying the quality of an item. Thus, when using any rule for deciding whether or not the process is in control, there is the possibility of being mistaken. Various probabilistic quantities of interest are derived for our rule.
