On Possibilistic Mean Value, Variance, Covariance and Correlation of Fuzzy Numbers

  • Chapter

Part of the book series: Studies in Computational Intelligence ((SCI,volume 243))

Abstract

In 2001 we introduced the notions of possibilistic mean value and variance of fuzzy numbers. In this paper we give a short survey of these notations and show some examples of their application from the literature.
