Abstract

Measurement uncertainty plays a very important role ensuring validity of decision-making procedures, since it is the main source of incorrect decisions in conformity assessment. The guidelines given by the actual Standards allow one to take a decision of conformity or non-conformity, according to the given limit and measurement uncertainty associated to the measured value. Due to measurement uncertainty, a risk of a wrong decision is always present, and the Standards also give indications on how to evaluate this risk, although they mostly refer to a normal probability density function to represent the distribution of values that can be reasonably attributed to the measurand. Since such a function is not always the one that best represents this distribution of values, this paper considers some of the most-often used probability density functions and derives simple formulas to set the acceptance (or rejection) limits in such a way that a pre-defined maximum admissible risk is not exceeded.

 

Author Biography

Simona Salicone, Politecnico di Milano

Simona Salicone is an Associate Professor of electrical and electronic measurements at Dipartimento di Elettronica, Informazione e Bioingegneria (DEIB), Politecnico di Milano.

Her principal research interests are concerned with the analysis of advanced mathematical methods for uncertainty representation and estimation. Her research activity is reflected in the over 100 papers published in international and national scientific journals, in the proceedings of national and international conferences in the field of instrumentation and measurements, and in two monographs, edited by Springer: “Measurement Uncertainty. An approach via the mathematical theory of evidence” (2007) and “Measuring Uncertainty within the Theory of Evidence” (2018).

In 2004 she has received, by the IEEE Instrumentation and Measurement Society, in recognition of contributions made to measurement uncertainty theory, the 2004 Outstanding Young Engineer Award. In 2007, Simona Salicone is elected, by the Officers and Board of Directors of the IEEE, to the grade of IEEE Senior Member. In years 2013 to 2017, Simona Salicone has been part of the Academic Board of the PhD in Electrical Engineering at Politecnico di Milano. Since 2014 until the end of 2016, she has been part of the Editorial Board of the IEEE Instrumentation and Measurement Magazine, as the responsible of the column “Future Trends in Instrumentation & Measurements”. Since January 2016 until the end of 2017, Simona Salicone has been the Associate Editor in Chief of the IEEE Instrumentation and Measurement Magazine. In 2016 Simona Salicone has received, in appreciation of outstanding service to IEEE Transaction on Instrumentation and Measurement, the recognition as one of the Transactions Outstanding Reviewers of 2015, by the IEEE Instrumentation and Measurement Society. Simona Salicone is the winner of the 2016 IEEE Instrumentation and Measurement Society Faculty Course Development Award.

In 2019, her monograph “Measuring Uncertainty within the Theory of Evidence” was among the top 25% most downloaded eBooks in its respective eBook Collection. In 2020, Simona Salicone has been recognized as a Top 70 Most Published Author of All Time by the IEEE Instrumentation and Measurement Society – Transaction on Instrumentation and Measurement.

Since 2019, Simona is part of the Selection Committee of the IEEE Faculty Course Development Award. Since 2021, she has been part of the Editorial Board of the MDPI Metrology journal.
