Measurement Uncertainty and Metrological Confirmation in Quality-oriented Organizations Measurement Uncertainty and Metrological Confirmation in Quality–oriented Organizations

The effect of measurement uncertainty on estimates and decisions performed under a regime of quality control and improvement, is considered in this paper. Standard statistical quality tools are analyzed such as control charts and instrument calibration procedures. Their performance is characterized under the assumption of both normally and uniformly distributed measurement uncertainty. Exact and approximate expressions are derived that allow the design of suitable procedures including the contribution of measurement uncertainty.
