New Method to Measure Similarity Between Intuitionistic Fuzzy Sets Based on Normal Distribution Functions

Intuitionistic fuzzy set is the generalization of fuzzy set.After investigating several kinds of existent similarity measures,a new kind of similarity measure based on normal distribution functions is presented.Compared with the existing methods,the proposed similarity measure is more reasonable and suited to any special situations.Moreover,this method is more reliable than which proposed by Wen-Liang Hung (2004) in applications with linguistic variables.It brings forth a brand-new method to deal with fuzzy information.
