KW - Interval-valued fuzzy number, weighted possibilistic mean, weighted
possibilistic variance, weighted possibilistic correlation.
AB - <p style="text-align: justify;">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.</p>
