Weighted Fuzzy Similarity Measure Based on Tangent Function and its Application to Medical Diagnosis

Surapati Pramanik, Kalyan Mondal

In this paper, the weighted tangent similarity measure of fuzzy sets is proposed and its properties are studied. The concept of the weighted tangent similarity measure of fuzzy sets is a decision making tool which is characterized by the degree of membership function, degree of non-membership function (sum of this two components is equal to one). Finally, using this proposed method, an application on medical diagnosis is given for the applicability of the proposed approach.
