In this paper we introduce a novel Similarity measure for Iintuitionistic fuzzy multi sets (IFMS) based on Zhang and Fu’s measure, as Similarity Measure is an important topic in fuzzy set theory. The unique feature of this method is that it considers multi membership, non membership and hesitancy degree for the same element. Since the proposed measure of IFMS is mathematically valid and demonstrates the superiority of the existing methods, we apply this measure to medical diagnosis and, pattern recognition problems.
