Abstract
In order to reduce the calculation cost of industrial plant evaluation, an industrial plant evaluation devicecomprises: a reception unitconfigured to receive an actual machine manipulated variable in process control of an industrial plant and an actual machine process variable to be controlled by the process control; an estimation unitconfigured to determine a process variable as an estimated process variable by using a process model defining a mathematical relationship between a manipulated variable and a process variable in the process control, the process variable as the estimated process variable being obtained by substituting the actual machine manipulated variable for the manipulated variable in the process model; and a comparison unitconfigured to compare the estimated process variable and the actual machine process variable with each other.
