On the WOWA operator and its interpolation function

The weighted ordered weighted averaging (WOWA) operator is one of the existing aggregation methods that can be used to fuse numerical data. The application of this operator to a set of data requires an interpolation function. In this paper, we present a few results about the sensitivity of the operator according to the interpolation method used. © 2009 Wiley Periodicals, Inc.Partial support by the Generalitat de Catalunya (2005 SGR 00446 and 2005-SGR-00093) and by the Spanish MEC (projects ARES: CONSOLIDER INGENIO 2010 CSD2007-00004 and eAEGIS: TSI2007-65406-C03-02) is acknowledged.Peer Reviewe
