Aggregation operators are functions that are used to aggregate individual suitability degrees and compute an overall suitability degree for evaluating decisions. One of the goals of this project is to analyze and compare various suitability aggregators. The emphasis is on new forms of interpolative aggregators, as well as new aggregators that combine idempotent and non-idempotent properties. The methodology for analysis will be based on the graphical presentation of aggregators and on the animation of the continuous transition between the extreme cases of aggregators (drastic conjunction to drastic disjunction). The goal also includes an analysis of the semantic components of decision models implemented using weights. The weights are used to define the relative importance of inputs to each aggregator. In particular, we study the impact of various forms of implicative weights and their suitability in aggregation that closely models human reasoning.
