Renoir, Pneumon-IA and Terap-IA: three medical applications based on fuzzy logic

The research at the IIIA has produced over more than a decade two versions of a tool for developing knowledge-based systems: Milord and Milord II. This tool has been mainly used for the development of medical applications. In this paper we summarize the Milord II approximate reasoning approach based on fuzzy sets, and three medical applications: rheumatology diagnosis (Renoir), pneumonia diagnosis (Pneumon-IA) and pneumonia treatment (Terap-IA).
