Theory of copulass and aggregation operators

 We have developed new results formulated in the frame of the theory of aggregation operators and their specific instance, theory of copulas. Main attention was focused on the algebraic properties of copulas, especially regarding their additivity, and on the parametric characterization of aggregation operators. The modern quantitative methods of the processing of realistic data contaminated by uncertainty or vagueness display evident trends of development aiming to modern and advanced mathematical methods of data representation and data processing under uncertainty, with special stress on the economic ones. Namely the copulas theory and triangular-norms theory closely related to it appear to represent the basic tools for handling those problems. Moreover, the analysis of copulas and triangular norms is widely developed in many countries (Italy, Austria, Slovakia, Ireland, Spain, France, Netherland, China, and others), and the successful results achieved by our team motivated wide and intensive international cooperation with partners from those countries.

Management of uncertainty in cooperation and communication 

Parallely with the investigation of the general models widely covering the field of potential methods of modern quantitative economy, some more applied problems of econometric modeling were intensively investigated. Namely, special attention was paid to two areas of interest. First of them is the modeling of cooperative behavior and its stability in optimization problems where the expected pay-offs are only vague. The study of these problems is a continuation of the research activities realized in the previous periods, and extends the results achieved in their frame. Qualitatively new topic of interest is represented by the analysis of the vague information sources and information with hardly identifiable alphabets and symbols. The fuzzy information theoretical analysis of the fuzzy information source aims to the applicable methods of analysis of such economic and econometric concepts like “expectation” and “Expected values” of some parameters entering, especially into prospective economic models.
