This was verified by trials with the following systems which were developed by our group in Vietnam a fuzzy expert system for syndromes differentiation in oriental traditional medicine an expert system for lung diseases using fuzzy logic case based reasoning for medical diagnosis using fuzzy set theory a diagnostic system combining disease diagnosis of western medicine with syndrome differentiation of oriental traditional medicine a fuzzy system for classification of western and eastern medications and finally a fuzzy system for diagnosis and treatment of integrated western and eastern medicine. All the above mentioned systems were developed and tested at the hospitals. 1. Introduction In recent years computational intelligence has been used to solve many complex problems by developing intelligent systems. And fuzzy logic has proved to be a powerful tool for decision-making systems such as expert systems and pattern classification systems. Fuzzy set theory has already been used in some medical expert systems. In traditional rule-based approach knowledge is encoded in
