PROBLEM TO BE SOLVED: To provide a state supervising system that can properly model a state of an instrument even in a case where the state of the instrument changes.;SOLUTION: A state supervising system 1 has: a phenomenon component storage unit 8 that stores a phenomenon component serving as a physical model in accordance with a phenomenon likely to occur in an instrument in advance; instrument data acquisition means 2 that acquires state data from sensors; model analysis result acquisition means 5 that acquires an analysis result simulated from the physical mode of the instrument; comparison means 3 that compares the state data with the analysis resu parameter adjustment means 6 that adjusts a parameter of the physical model; phenomenon component selection means 7 that takes the physical component in to the physical mode; and phenomenon component control means 4 that, on the basis of a comparison result of the comparison means, instructs phenomenon component selection means to select the phenomenon necessary for the physical model and adjust the parameter of the selected phenomenon component.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
