1. A plant operation optimization support device for improving an efficiency of a plant operation, the plant operation optimization support device in communication with a processor, memory and storage, the plant operation optimization support device comprising:
an input device that inputs an operation amount signal provided to a plant and a process signal detected by the plant as input signals;
a sensitivity estimation device that requires a time-series change of the process signal as for the operation amount signal, as a sensitivity signal;
a signal classification device that classifies an operation state of the plant from the input signals to provide an operation state signal and that extracts the sensitivity signal indicating a high sensitivity from the sensitivity signals in every classified operation state, as a state-classified high sensitivity signal;
a display device configured to present the operation state signal and the state-classified high sensitivity signal provided by the signal classification device as a displayed data;
a control device that determines the operation amount signal provided to the plant based upon the displayed data including at least the operation state signal and the state-classified high sensitivity signal, and
a control rule optimization device that, on receipt of the state-classified high sensitivity signal, determines an optimized control rule in a plant control for transition to a target state and provides the above as a control rule signal to the control device, when a high efficiency operation state of the plant is defined as the target state,
wherein based upon at least the state-classified high sensitivity signal, an amount of data from the input signals required for the determination of the operation amount signal is reduced, and
the plant operation transitions to the target state based upon the optimized control rule.
