Abstract: An information processing device includes a controller that: inputs information that is based on a raw material of a product that is produced at a plant to a physical model and acquires a first output result; inputs component information that is based on optical spectrum data that are obtained by spectroscopic sensing for the raw material and an output of the physical model to a machine learning model and acquires a second output result; and outputs information concerning a state of the plant based on the first output result and the second output result.

Abstract: An information processing device includes a controller and a display. The controller acquires a first prediction result that indicates information concerning a state of a plant that is predicted by a physical model, and acquires a second prediction result that indicates information concerning a state of the plant that is predicted by a machine learning model that is generated based on data concerning the plant. The display displays the first prediction result and the second prediction result.

Abstract: A plant operation support device for simulating an operation of a plant based on information obtained from the plant, includes: an operation condition setting part that sets an operation condition of the plant and a timing for applying the operation condition; and a transient state prediction part that predicts a transient state of the plant from a specific time point to the future in a case in which the operation condition of the plant set by the operation condition setting part is applied at the timing.

Abstract: Provided is a plant operation support apparatus including a plant simulator, a predictor, and a predicted KPI deriver. The plant simulator simulates a state at a current time or a predetermined time of a plant based on information obtained from the plant, to output an estimated value at the current time or the predetermined time of process data in the plant. The predictor predicts a state at a predetermined future time of the plant based on the estimated value and outputs a predicted value of the process data in the plant. The predicted KPI deriver derives a predicted KPI which is an index for monitoring the state at the future time of a task to be monitored in plant operation based on the predicted value.
