- Abstract:
- In this paper, a task-specific measuring capability criterion is described, applicable to select or validate measurement systems that provide data to set the process aim, when the techniques known as "sequence of values" or "difference chart" are used. The criterion is based on the estimation of the "uncertainty of the process mean", which characterizes the dispersion of the values that could reasonably be attributed to the process mean after the setting procedure. The proposed criterion is compared with the discrimination ratio and with the uncertainty per tolerance ratio, showing that the last one fails to predict the measuring capability for aim-setting operations.
