Zadeh defined fuzzy set with membership function A=μA(x ) for the proposition of the type “x is A”. Fuzzy set with single membership function is not sufficient to deal with uncertain information. The fuzzy set with two fuzzy membership functions will give more evidence to deal with uncertainty. In this paper, fuzzy set is defined by generalized fuzzy set A={μABelief(x), μDisbelief(x)} with the two fuzzy membership functions based on Belief and Disbelief. The fuzzy inference and the fuzzy reasoning are studied with generalized fuzzy set. The fuzzy conditional inference for "if … then …" and "if … then … else" are discussed with two fuzzy membership functions, also Fuzzy Certainty Factor is defined with difference between "Belief" and "Disbelief" membership functions to made as single fuzzy membership function. An Medical Expert System is discussed as one of the applications of Generalized fuzzy set. In EMYCIN, Belief anf Disbelief are defined with Probability. In this paper, generalized fuzzy sets are discussed for EMYCIN.Keywords

Medical Expert Systems is one of the challenging area in Artificial Intelligence in Medicine. Medical Expert Systems will act as domain expert (Doctor in Medical diagnosis. Usually information available to the medical diagnosis is inexact rather than exact. Medical Expert System has to deal with inexact information. The Medical inexact information is fuzzy rather than probable (likelihood). In this paper, Fuzzy logic and Fuzzy Knowledge Represention are discussed for Medical diagnosis. Medical Expert Systems and Fuzzy Medical Expert System (FMES) are discussed for Medical diagnosis. Examples are discussed with MYCIN and Prolog for Medical diagnosis. Medical diagnosis is distributed because the Medical information has to garter from various sources. The Fuzzy Medical Expert Systems are to be co-operated and co-ordinate in distributed environment in the distributed environment. Distributed Fuzzy Medical Expert System(DFMES) is studied for Medical diagnosis.Keywords
