Abstract

We propose a new approach for medical diagnosis by employing intuitionistic fuzzy sets [cf. Atanassov [1,2]]. Solution is obtained by looking for the smallest distance [cf. Szmidt and Kacprzyk [7,8]] between symptoms that are characteristic for a patient and symptoms describing illnesses considered. We point out advantages of this new concept over the method proposed by De, Biswas and Roy [4] where intuitionistic fuzzy sets were also applied, but the max-min-max rule was used instead of taking into account all, unchanged symptom values as proposed in this article.
