Plant evaluation system, plant evaluation method, and program

A plant evaluation system comprising:

• a plant form information acquisition unit configured to receive an input of plant form information in which a combination of configurations of devices installed in a plant is decided;
• a condition acquisition unit configured to receive an input of a condition related to evaluation of the plant indicated by the plant form information;
• a storage unit configured to store various pieces of information necessary for a process of evaluating the plant;
• a performance information calculation unit configured to calculate performance of the plant in which a secular change occurring in the plant during an evaluation target period included in the condition is reflected according to a secular change model stored in the storage unit;
• and
• an optional component selection unit configured to select a component which is used for at least one of the devices included in the plant and improving performance of the device,
• wherein the performance information calculation unit is configured to calculate the performance of the plant in which an improvement of the performance of the device by the component selected by the optional component selection unit is reflected.

A plant evaluation method in a plant evaluation system, comprising:

• a step of receiving an input of plant form information in which a combination of configurations of devices installed in a plant is decided;
• a step of receiving an input of a condition related to evaluation of the plant indicated by the plant form information;
• a step of calculating performance of the plant in which a secular change occurring in the plant during an evaluation target period included in the condition is reflected according to a secular change model stored in a storage unit included in the plant evaluation system;
• and
• a step of selecting a component which is used for at least one of the devices included in the plant to improve performance of the device,
• wherein in the step of calculating of the performance of the plant, the performance of the plant in which an improvement of the performance of the device by the selected component is reflected is calculated.

A program causing a computer included in a plant evaluation system to function as:

• a means for receiving an input of plant form information in which a combination of configurations of devices installed in a plant is decided;
• a means for receiving an input of a condition related to valuation of the plant indicated by the plant form information;
• a means for calculating performance of the plant in which a secular change occurring in the plant during an evaluation target period included in the condition is reflected according to a secular change model stored in a storage unit included in the computer;
• and
• a means for selecting a component which is used for at least one of the devices included in the plant and improving performance of the device,
• wherein the means for calculating the performance of the plant is configured to calculate the performance of the plant in which an improvement of the performance of the device by the selected component is reflected.
