Emrouznejad, A. (2008). “MP-OWA: The most preferred OWA operator.” Knowledge-Based Systems 21(8): 847-851. In practical term any result obtained using an ordered weighted averaging (OWA) operator heavily depends upon the method to determine the weighting vector. Several approaches for obtaining the associated weights have been suggested in the literature, in which none of them took …
