Abstract:
A normally distributed fuzzy variable is defined by a unimodal and symmetric membership function, and is proved to be the most uncertain one when expected value and variance are given. In this note, a lognormally distributed fuzzy variable is defined and the membership function, expected value and variance of this variable are discussed. Based on these results, some properties about geometric Liu process are given. |
| Keywords and phrases: fuzzy variable, expected value, variance, fuzzy process. |
