FAULT DIAGONISTIC EXPERT SYSTEM AND DIAGONISTIC METHOD

摘要

The present invention relates to a fault diagnosis expert system and a fault diagnosis method that can improve the reliability of a result of failure by using a case-base of past fault diagnosis information. The fault diagnosis expert system of the present invention includes a first process of case-baseting current fault diagnosis information, a second process of drawing a possible element that can be predicted as a fault with information of the current fault situation by using a matching algorithm, The third step of finding the most similar case of past failure cases by comparing current failure cases established by using the ranking algorithm and past failure diagnosis information, and determining whether to register the current failure cases in the previous failure cases. 4th process.
