Application of a modified OWA operator to a designer decision aiding system (DDAS)
DDAS is an intelligent system, which provides active support to decision-makers in various contexts. In decision making over unstructured problems, the ability to actively converge to an operational problem description is fundamental. This, in turn, means that evaluations of that description according to ways of dealing with it should eventually be provided, As a result, an aggregation operator, capable of combining criteria/problems in a way similar to human reasoning, is required. This paper presents DDAS and an aggregation operator based on Ordered Weighted Averaging that is used in DDAS in order to approximate the preference ordering carried out by decision-makers.
