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 an
overlap functions and we discuss 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 analysed. We specially focus on the
homogeneity and migrativity properties.
