Medical Diagnostic Reasoning Using a Similarity Measure for Intuitionistic Fuzzy Sets

We propose a new similarity measure for intuitionistic fuzzy sets (cf. Atanassov [1, 2]) and show its usefulness in medical diagnostic reasoning. We point out advantages of this new concept over the method proposed previously (cf. Szmidt and Kacprzyk [23]) where distances were used instead of the proposed similarity measure.
