On intuitionistic fuzzy modal operators in medical diagnosis

In this paper we propose a new approach for Medical diagnosis with the symptoms of disease using IFS with modal operators. These operators apply to identify the disease of the patient with symptoms in the data. The membership and non-membership values are not always possible upto our satisfaction, but in deterministic(hesitation) part has more important role here, the fact that in decision making, particularly in case of medical diagnosis, there is a fair chance of the existence of a non-zero hesitation part at each moment of evaluation.
