Aggregation of fuzzy aalpha;-C-equivalences

The article deals with notions of fuzzy equivalences, where transitivity is defined by the use of a fuzzy conjunction. In particular fuzzyC-equivalences and fuzzy -C-equivalences are considered. Moreover, the problem of the preservation of their axioms by some aggregation functions is examined. This paper gives a contribution to the discussion of tolerance analysis in soft computing, decision making, approximate reasoning, information fusion problems, and fuzzy control.
