DECISION MAKING IN COMPLEX ENVIRONMENTS WITH UNCERTAIN GENERALIZED UNIFIED AGGREGATION OPERATORS

A new decision making approach is presented where the available information is uncertain and can be assessed with interval numbers. We consider complex environments where the available information is formed by using different sources of information that have to be considered in the analysis. We introduce a new aggregation operator adapted for these situations that we call the uncertain generalized unified aggregation operator (UGUAO). It includes a wide range of classical aggregation operators in the same formulation.
