 Ordered weighted averaging aggregation operator

The Ordered Weighted Averaging (OWA) aggregation operator is a mathematical tool used in decision-making and aggregation tasks, particularly in scenarios where decision criteria are uncertain, and risk attitudes need to be accounted for. The OWA operator was introduced by Ronald R. Yager in the late 1980s as part of the field of fuzzy set theory and based on the concept of ordered structures in data.
