This paper will introduce a new method to obtain the order weights
of the Ordered Weighted Averaging (OWA) operator. We will first show the
relation between fuzzy quantifiers and neat OWA operators and then offer a
new combination of them. Fuzzy quantifiers are applied for soft computing
in modeling the optimism degree of the decision maker. In using neat operators,
the ordering of the inputs is not needed resulting in better computation
efficiency. The theoretical results will be illustrated in a water resources management
problem. This case study shows that more sensitive decisions are
obtained by using the new method.
