Appendix E – Calculation of the Mean Value and Variance of Fuzzy Numbers

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


This appendix describes the expressions deduced for calculating the mean value and variance of fuzzy numbers presented by Carlsson and Fullér in [1]. These definitions are consistent with the extension principle and with the definitions of mean and variance in probability theory.
