Abstract

The WOWA operator is an aggregation operator that generalizes the weighted mean and the OWA operator. In this paper we study the sensitivity of this operator with respect to the interpolation method used in its calculation. We analyze the sensitivity with respect to the orness and dispersion (entropy) of the weighting vector.
