<p><P>PROBLEM TO BE SOLVED: To provide a system and method for easily and accurately determining whether the state of a plant is abnormal or normal. <P>SOLUTION: This system comprises a characteristic quantity extraction part 30, a detection part 20 detecting a state quantity showing an operating state of a plant 90, and a database 40. The database 40 stores the state quantities detected by the detection part 20 in conformation to time. The characteristic quantity extraction part 30 generates characteristic quantity groups based on the continued state quantities detected in a predetermined period up to a plurality of times T(i) in reference to the database 40, and outputs the relation between the characteristic quantity groups for each of the plurality of times T(i). <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
