Multi-polar aggregation

Abstract

In this contribution we introduce a notion of an m-polar aggregation operator as a generalization of aggregation operators and bipolar aggregation operators, and we introduce the main properties of these aggregation operators. Extensions of some (bipolar) aggregation operators to m-polar aggregation operators are also introduced, as well as metrics on the category space K × [0,1] related to m-polar aggregation. © 2012 Springer-Verlag Berlin Heidelberg.
