The authors have developed a diagnosis system with a Fuzzy inference on a personal computer. In this system, we use the membership functions for evaluating data and can get the excellent detecting ability in borderline cases. One of the characteristrics of the new system is a multi-layer structure. As we can examine one case from many point of view, we can often find combined disease. Moreover, We can easily use the information which denies the probability of some disease, and become able to rule out a lot of disease more exactly.
