Abstract: There is provision of an operation support system for supporting an operation of a demand-supply system including a resource supplying facility and a resource demander facility. The operation support system receives an input of a demand-supply system model of the demand-supply system, facility-capacity information of the resource supplying facility, and analysis condition information defining a plurality of variables and an external variable of the demand-supply system, to generate a correlation logical formula representing a relation among the plurality of variables and the external variable. The operation support system further acquires performance data of the demand-supply system which includes actual values of the plurality of variables and the external variable during an operation, and renders an area represented by the correlation logical formula when the external variable is equal to an actual data included in the performance data and a point represented by the performance data of the plurality of variables.

Abstract: A control device is configured to calculate a difference between a target value and a current value of a controlled variable for a control target; store predicted values obtained by forgetting a predicted value of the controlled variable that is predicted in a past time by a plant response function; calculate a corrected difference from the difference and a predicted value of the controlled variable after a predetermined lookahead length elapses, based on the predicted values; calculate a change in a value of a manipulated variable based on the corrected difference and a predetermined control gain; calculate a new value of the manipulated variable by adding the change of the value of the manipulated variable to the value of the manipulated variable; and output the new value of the manipulated variable to the control target so that a value of the controlled variable is caused to track the target value.

The design assist device generates a response prediction formula predicting a variation value of the control amount at each control timing included in the sequence of control timings by using an amount of change of the operation amount at each operation timing included in the sequence of operation timings; generates evaluation formulas; and converts a logical product formula into a first first-order predicate logical formula. The design assist device generates a control logical formula indicating a relationship between the current value of the target deviation and the change amount of the operation amount.
