PLANT MODEL CONSTRUCTION SUPPORT SYSTEM

PROBLEM TO BE SOLVED: To provide a plant model construction support system which can support gradual refinement of a plant simulator on the basis of detailed facility data to be gradually acquired when a detailed model and a statistical model of each facility coexist.SOLUTION: The plant model construction support system includes a detailed model group 12 for expressing facility characteristics with a detailed model and a simple model group 13 for expressing the facility characteristics with a simple model such as a statistical expression, performs signal separation of operation data by a model other than the detailed model group 12 for each target facility, performs a gradual parameter update of the facility model of the simple model group 13 with the data in which the signal has been separated, and thereby gradually constructs a plant simulator 1.
