Generalized interval-valued OWA operators with interval weights derived from interval-valued overlap functions

In this work, we extend to the interval-valued setting the notion of overlap functions, presenting a method which makes use of interval-valued overlap functions for constructing OWA operators with interval-valued weights. Some properties of interval-valued overlap functions and the derived interval-valued OWA operators are analyzed. We specially focus on the homogeneity and migrativity properties.
