<P>PROBLEM TO BE SOLVED: To provide a method and a system of abnormality detection/diagnosis capable of detecting abnormality with high sensitivity and at an early stage in facilities such as a plant. <P>SOLUTION: Abnormality detection is performed using operation information such as operating time of a facility and output signals of multiple sensors attached to the facility. With a maintenance history such as a work report including past measure examples such as a work history and replacement part information, measures for the detected abnormality are associated, the abnormality detection and the past maintenance history are linked together, and a facility record is consulted, to classify and present the abnormality which needs action. Thus, the accuracy of diagnosis can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
