Intuitionistic fuzzy approach to n-ary systems

We adopt the fundamental concepts of intuitionistic fuzzy subalgebras to n-ary groupoids, i.e., on algebras containing one n-ary operation. We describe some similarities and differences between the n-ary and binary case. In the case of n-ary quasigroups and groups we suggest the common method of investigations based on some methods used in the universal algebra.
