Abstract:
The present research aims to detect certain correlations between four economic indicators, against which
have been evaluated the economic entities of the European Union with 27 Member States, as split into four
categories: micro, small, medium and large enterprises. The mathematical formalism employed for
revealing these dependencies, particularly termed here ‘positive’ and ‘negative consonances’, is a novel
decision support approach, called InterCriteria Analysis, which is based on the theoretical foundations of the
intuitionistic fuzzy sets and the augmented matrix calculus of index matrices. The proposed approach can be
useful in processes of decision making and policy making, and it can be seamlessly integrated and further
extended to other related application areas and problems, where it is reasonable to seek correlations between
a variety of economic and other indicators.
