Sensitivity analysis for WOWA, OWA and WM operators

This work is focused on the analysis of the sensitivity of some aggregation operators of the Choquet integral family: the ordered weighting averaging (OWA) operator, the weighted OWA (WOWA), the weighted mean and the arithmetic mean. We show that the arithmetic mean is the one with less sensitivity and that the behavior of OWA, WM and WOWA for small errors is different than the case of large errors.
