Expert System for the Evaluation of Measurement Uncertainty: Making Use of the Software Tool uncertaintyMANAGER®

Abstract

An expert system for the evaluation of the measurement uncertainty is presented. It follows the four-step process established by the Eurachem/CITAC guide QUAM. The expert system provides a considerably better estimate of the overall measurement uncertainty than certain summary approaches used nowadays in most private and public laboratories and in industry. This is demonstrated by an example from the production control in a pharmaceutical lab. In addition, the expert system allows performing the entire process to evaluate the measurement uncertainty much faster than the summary approaches used in industry.
