Abstrakt:
The paper presents basic notions of intuitionistic fuzzy sets and fuzzy inference
systems of Mamdani type for the consecutive design of intuitionistic hierarchical fuzzy
inference systems. On the basis of the given concept, we design and formalize tree
intuitionistic hierarchical fuzzy inference systems of Mamdani type. Moreover, we present a
classification problem realization for an example of municipal creditworthiness modelling.
