  The ordered weighted averaging (OWA) operators play a crucial role in
aggregating multiple criteria evaluations into an overall assessment supporting
the decision makers' choice. One key point steps is to determine the associated
weights. In this paper, we first briefly review some main methods for
determining the weights by using distribution functions. Then we propose a new
approach for determining OWA weights by using the RIM quantifier. Motivated by
the idea of normal distribution-based method to determine the OWA weights, we
develop a method based on elliptical distributions for determining the OWA
weights, and some of its desirable properties have been investigated.
