To perform, not by trial and error, the fast and most appropriate controlled operation.
On the basis of operation data 11, a parameter 19 for nonlinear differential equations representing a nonlinear physical model 18 is identified, and the nonlinear physical model 18 is converted into a nonlinear optimization problem 23 that seeks optimum value solutions for manipulated variables. The objective function is a function having, as its variable, the variable u (t) of the nonlinear physical model 18, the discrete optimum value solution u (t) obtained when the objective function is optimized is outputted just as it is as the sequence logic for the operation, and its solution is obtained speedily. It is possible, by connecting a computation center and plants in various locations on-line, to use the latest operation data for the optimum operation more precisely, coping with the aged deterioration quickly.
