Similarity Measure of Intuitionistic Fuzzy Numbers by the Centroid Point

The aim of the paper is to introduce a new similarity measure between intuitionistic fuzzy numbers (IFNs). The proposed method is based on the centroid point of IFNs. It is also proved that the proposed measure satisfies the properties of similarity measure. Examples are considered to compare the proposed similarity measure with the existing similarity measures. The similarity results show that the new similarity measure can overcome the faults of the existing similarity measures.
