- Abstract:
- In the last years, the Authors have proposed the use of the Random-Fuzzy Variables (RFVs) to represent measurements results. An RFV is an extension of a fuzzy variable, which is the natural variable in the mathematical possibility theory (in the same way the random variable is the natural variable in the probability theory). The aim of this presentation is to show, through a remotely controlled Virtual Instrument (VI) (accessible via the web page http://131.175.120.11:8000/RFVcalculator.html), how RFVs are built, starting from the available information about the uncertainty contributions affecting the measurement results; how they are combined, considering also the possible correlations between the uncertainty contributions; and how they are compared.
