A Tool for Decision Making Assistance: SPHINX

This paper presents a system for medical aided-diagnosis, the SPHINX system, based on methods of inference and pattern-matching used in Artificial Intelligence and on various heuristic features: fuzzy heuristics in relation with the suggestion power of the signs and heuristics based on the costs of complementary investigations. The first application was achieved in the diagnosis of epigastric pain. Its results are presented and discussed in the paper.
