The basic operations for combining real values are the weighted mean (WM)and the Ordered Weighted Averaging (OWA) operator. The weighted mean allows the system to compute an aggregate value from the ones coming from several sources, taking into account the reliability of each information source. Alternatively, the OWA operator allows the user to weight the values supplied in relation to their alternative ordering. The Weighted OWA operator (WOWA) allows the user to consider both aspects using two sets of weights. In this chapter we describe an extension of the WOWA operator to the continuous case after arguing its convenience. Then, we analyze the use of this operator for defuzzification.
