Abstract

In this paper we will analyze some computational problems related with ordered hierarchical aggregations of OWA operators as defined by the authors in a previous paper. In particular, we will provide polynomial algorithms to maximize or minimize the degrees of dispersion and orness of the hierarchical OWA aggregation.
