Abstract: An information processing device includes a data acquisition unit that acquires process data of target equipment, a first index value calculation unit that calculates a first index value related to operation of the target equipment based on the process data, a second index value calculation unit that calculates a second index value related to the operation of the target equipment based on the process data, and a display control unit that displays a coordinate space defined by an axis denoting the first index value and by an axis denoting the second index value and a representative point of the process data in the coordinate space on a display unit.

Abstract: Provided is a display device including a display screen, in which a plurality of evaluation models are configured to be displayed in a selectable manner in a first display area of the display screen, an evaluation result of evaluation data, which is obtained by using a selected first evaluation model, is configured to be displayed in a second display area of the display screen, and an evaluation result of the evaluation data, which is obtained by using a selected second evaluation model, is configured to be displayed in a third display area of the display screen.

Abstract: A diagnosis apparatus includes: a sensor that detects diagnosis target information generated by a diagnosis target device; a threshold setting unit that sets a threshold for the diagnosis target information; and a diagnosis unit that diagnoses the diagnosis target device based on the diagnosis target information detected by the sensor and the threshold, in which the threshold setting unit sets the threshold based on the diagnosis target information in a predetermined period before a diagnosis time point, and the diagnosis unit performs diagnosis based on a current time point threshold set at the diagnosis time point and at least one past threshold set in the past.

Abstract: A prediction system includes a storage unit that stores a history of an operation state of each of a plurality of target devices and attribute information indicating an attribute of each of the plurality of target devices; a first acquisition unit that acquires an attribute information filter condition in which at least one attribute information included in attribute information of a prediction target device is specified; a second acquisition unit that acquires an operation state filter condition in which at least one operation state included in a history of an operation state of the prediction target device is specified; an extraction unit that extracts a history of an operation state of a target device satisfying the attribute information filter condition and the operation state filter condition; and an estimating unit that predicts the operation state of the prediction target device based on the extracted history of the operation state.

Abstract: Provided is a supporting device for supporting an operation of a plant. The supporting device includes a question output unit that outputs a question based on process data of the plant; an answer reception unit that receives an answer to the question output from the question output unit; and an estimation information output unit that outputs estimation information that supports the operation of the plant on the basis of the answer received by the answer reception unit.
