Intuitionistic Fuzzy Soft Set

The concept of intuitionistic fuzzy soft set (IFSS) which combines the advantage of soft set and K. Atanassov's intuitionistic fuzzy set (IFS) is proposed. Then some basic notions of IFSS are presented. Based on the "Complement", "intersection", "union" operations on IFS theory, the "Complement", "intersection", "union", "AND" and "OR" operations of IFSS are defined. At last, some properties of the above operations are discussed.
