The WOWA operator (Weighted OWA) was proposed as a generalization of both the OWA and the Weighted mean. Formally, it is an aggregation operator that permits the aggregation of a set of numerical data with respect to two weighting vectors: one corresponding to the one of the weighted mean and the other corresponding to the one of the OWA. In this chapter we review this operator as well as some of its main results.
