Abstract

In this paper, the concept of weighted possibilistic mean of interval-valued fuzzy number is first introduced. Further, the notions of weighted possibilistic variance, covariance and correlation of interval-valued fuzzy numbers are presented. Meantime, some important properties of them and relationships between them are studied.

Keywords:

Interval-valued fuzzy number weighted possibilistic mean weighted possibilistic variance weighted possibilistic correlation.
