Smart Metrology
{{short description|Approach to industrial metrology}}{{Advert|date=December 2023}}
Smart Metrology is a modern approach to industrial metrology. The name was introduced by Jean-Michel Pou and Laurent Leblond, a French meteorologist and a French statistician. The term was coined in their book, La Smart Metrology: De la métrologie des instruments à la métrologie des décisions.{{Cite book|last=Pou, Jean-Michel.|url=https://www.worldcat.org/oclc/952466728|title=La smart metrology : de la métrologie des instruments à la métrologie des décisions|date=2016|publisher=AFNOR Editions|others=Leblond, Laurent, (19 ... – ... ; expert en statistique industrielle), Nordon, Didier.|isbn=978-2-12-465545-8|location=La Plaine Saint-Denis|oclc=952466728}} It was then adopted by Deltamu, a French company providing services in the field of industrial metrology.
The approach promoted by Smart Metrology applies the exploitation of data and information, including that provided by big data,{{Cite journal|last1=Mari|first1=Luca|last2=Petri|first2=Dario|date=2017|title=The metrological culture in the context of big data: managing data-driven decision confidence|url=https://ieeexplore.ieee.org/document/8036688|journal=IEEE Instrumentation & Measurement Magazine|volume=20|issue=5|pages=4–20|doi=10.1109/MIM.2017.8036688|s2cid=19784029 |issn=1094-6969|url-access=subscription}} to implement an approach based on the three pillars of metrology{{Cite journal|last=Ferrero|first=Alessandro|date=2015|title=The pillars of metrology|url=https://ieeexplore.ieee.org/document/7335771|journal=IEEE Instrumentation & Measurement Magazine|volume=18|issue=6|pages=7–11|doi=10.1109/MIM.2015.7335771|hdl=11311/984646 |s2cid=20051541 |issn=1094-6969|hdl-access=free}} (uncertainty,JCGM 100:2008, Evaluation of measurement data — Guide to the expression of uncertainty in measurement, 2008, https://www.bipm.org/utils/common/documents/jcgm/JCGM_100_2008_E.pdf calibration and traceability) in industrial applications.{{Cite journal|last1=Lazzari|first1=Annarita|last2=Pou|first2=Jean-Michel|last3=Dubois|first3=Christophe|last4=Leblond|first4=Laurent|date=2017|title=Smart metrology: the importance of metrology of decisions in the big data era|url=https://ieeexplore.ieee.org/document/8121947|journal=IEEE Instrumentation & Measurement Magazine|volume=20|issue=6|pages=22–29|doi=10.1109/MIM.2017.8121947|s2cid=22216034 |issn=1094-6969|url-access=subscription}}
Approach
The approach suggested by Smart Metrology is fully framed within the ISO 9001 recommendations. Usual metrology is often regarded as a pure cost and is actually not following the ISO 9001 quality standards.

Smart Metrology follows a different approach according to the following steps:
- The measuring equipment is monitored using historical and relevant data to detect whether a doubt exists. If such a doubt exists, the equipment is calibrated.
- The available (a priori) information is used by applying advanced statistical approaches, such as Bayesian inference, for monitoring and is used in the decision-making process.{{Cite journal|last1=Pou|first1=Jean-Michel|last2=Leblond|first2=Laurent|date=2018|title=ISO / IEC guide 98-4: A copernican revolution for metrology|url=https://ieeexplore.ieee.org/document/8515699|journal=IEEE Instrumentation & Measurement Magazine|volume=21|issue=5|pages=6–10|doi=10.1109/MIM.2018.8515699|s2cid=53232687 |issn=1094-6969|url-access=subscription}}{{Cite book|last1=Ferrero|first1=Alessandro|last2=Salicone|first2=Simona|last3=Jetti|first3=Harsha Vardhana|title=19th International Congress of Metrology (CIM2019) |chapter=Bayesian approach to uncertainty evaluation: Is it always working? |editor-first1=Sandrine |editor-last1=Gazal |date=2019|url=https://cfmetrologie.edpsciences.org/articles/metrology/abs/2019/01/metrology_cim2019_16002/metrology_cim2019_16002.html|language=en|publisher=EDP Sciences|pages=16002|doi=10.1051/metrology/201916002|isbn=978-2-7598-9069-9|doi-access=free}}
- The calibration intervals were not at fixed intervals.
Smart Metrology and big data
Smart Metrology plays a key role in ensuring the reliability of data in the context of Big Data. This technological paradigm is defined by the ability to collect and store vast volumes of data from diverse sources, and to process them using advanced computing techniques, including Artificial Intelligence (AI).
In such data-driven environments, the veracity of the data becomes a fundamental requirement. The primary mission of Smart Metrology is to ensure the reliability of measured values, thus enabling accurate and meaningful decision-making. Unlike traditional approaches that focus mainly on compliance with standards, Smart Metrology incorporates risk management and measurement uncertainty as central components of the decision-making process.
Additionally, Smart Metrology promotes the use of a priori knowledge—previous understanding of the system or entity being measured—to improve the interpretation of measurement results. This approach helps reduce uncertainty and enhances the accuracy of predictions and industrial control systems.{{Cite journal |last1=Pou |first1=Jean-Michel |last2=Leblond |first2=Laurent |title=Smart Metrology: From the metrology of instrumentation to the metrology of decisions |journal=International Journal of Metrology and Quality Engineering |volume=8 |year=2017 |pages=205–209 |doi=10.1051/ijmqe/2017020 |url=https://www.researchgate.net/publication/319897264_Smart_Metrology_From_the_metrology_of_instrumentation_to_the_metrology_of_decisions |doi-access=free }}
