The fuzzy logic and fuzzy set theories were introduced by Prof. Zadeh in the 1960s and are consolidated in various areas of the human knowledge. Fuzzy logics have also been used in conjunction with FCA in order to provide a way of handling continuous attributes. In this presentation, FCA and fuzzy logics were briefly introduced, as well as some applications.
