Probabilities in the OWA operator

Expert Systems With Applications, 2012
We analyze the use of the probability in the ordered weighted average (OWA). We introduce the probabilistic OWA (POWA) operator. It is an aggregation operator that provides a parameterized family of aggregation operators between the minimum and the maximum that considers the degree of importance that the probability and the OWA operator have in the ...

MP-OWA: The most preferred OWA operator

Knowledge-Based Systems, 2008
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 into account the preference of alternatives.

On the orders of OWA operators

Journal of Intelligent & Fuzzy Systems, 2023
In this paper, we propose a partial ordering ⪯ on the set of ordered weighted averaging (OWA) operators. Based on this relation ⪯, we introduce the negation, conjunction and disjunction operations, and establish a bounded De Morgan lattice equipped with an involutive negation for OWA operators.

Two new models for determining OWA operator weights

Computers and Industrial Engineering, 2007
The determination of ordered weighted averaging (OWA) operator weights is a very crucial issue of applying the OWA operator for decision making. This paper proposes two new models for determining the OWA operator weights.

On the Comparisons of OWA Operators and Ordinal OWA Operators

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 1997
In this paper, comparisons of OWA operators and ordinal OWA operators are carried out by using lattice theoretic methods. It is proved first that in both cases, the set of all aggregation operators forms a lattice, then the concept of positive valuation is used to measure the "orness" of aggregation operators and the structures of all such possible ...

How well does the OWA operator represent real preferences?

European Journal of Operational Research, 2017
We present the results of an empirical study, in which we analyze the ability of the Ordered Weighted Average (OWA) operator to model actual preferences in a multi-attribute ranking task. We compare the OWA to a competing model (Simple Additive Weighting

Stancu OWA Operator

IEEE Transactions on Fuzzy Systems, 2015
A critical issue when selecting an ordered weighted aggregation (OWA) operator is the determination of the associated weights. For this reason, numerous weight generating methods have appeared in the literature. In this paper, a generalization of the binomial OWA operator on the basis of the Stancu polynomial is proposed and analyzed.
