摘要： A prediction control development device according to one aspect of the present invention generates a prediction model of a control amount by analyzing first time-series data of the control amount and provides the generated prediction model to a controller. The prediction control development device acquires second time-series data showing transition of a value of the control amount during prediction control using the prediction model, and evaluates prediction accuracy of the prediction model based on a difference between a prediction value by the prediction model and a value of the second time-series data. When the prediction accuracy of the prediction model is not allowable, the prediction control development device analyzes the second time-series data to newly generate a prediction model of the control amount, and provides the newly generated prediction model to the controller.

摘要： Prediction control of a manufacturing device is appropriately performed. A control device according to an aspect of the present invention executes a step of starting a computation processing of a prediction model; a step of computing a remaining processing time until the computation processing is completed after starting the computation processing of the prediction model; a step of determining whether the determination of the command value based on an output obtained from the prediction model is made within a control timing for controlling the operation of manufacturing by the manufacturing device, on the basis of a computed remaining processing time; and a step of stopping, when it is determined that the determination of the command value is not made within the control timing, the computation processing of the prediction model, determining the command value on the basis of a value of an intermediate result of the computation processing, and controlling the operation of the manufacturing device on the basis of the determined command value.

摘要： A technology for performing prediction control by which performance of a prediction model can be sufficiently exerted. A control system according to an aspect of the present invention estimates a numerical value range within which a command value can fall from a distribution of second data relating to the command value in a learning data set used to construct a prediction model, and in such a manner that a first acceptable range prescribed by a preset first threshold value with respect to a command value for a subject device is extended, decides a second threshold value with respect to the command value for the subject device on the basis of the estimated numerical value range. Further, in an operational phase, on the basis of an output value from the prediction model, the control system decides a command value for the subject device within a second acceptable range prescribed by the decided second threshold value, and controls an operation of the subject device on the basis of the decided command value.

摘要： The accuracy of analysis of data to be processed can be improved. An industrial control apparatus that causes a common processing unit to execute a first execution task for executing processing that does not depend on the number of pieces of data and a second execution task for executing processing that depends on the number of pieces of data, and an assistance apparatus are included. The industrial control apparatus calculates a control load amount of a processing unit incurred by executing the first execution task, and extracts the second execution task from the first and second execution tasks. The assistance apparatus calculates a processing load amount of the processing unit according to the type of the extracted second execution task for the number of pieces of analysis data, and using this processing load amount and the control load amount, calculates a margin of processing that indicates a degree of remaining processing capability of the processing unit.

摘要： An acquiring section acquires a plurality of observed data that are observed data observed from an object of control and that express combinations of explanatory variables and objective variables. A teacher learning section, on the basis of the plurality of observed data acquired by the acquiring section, trains a model for outputting the objective variable from the explanatory variable, and generates a learned teacher model. A learning data generating section, by inputting a predetermined explanatory variable to the teacher model generated by the teacher learning section, acquires a predetermined objective variable with respect to the predetermined explanatory variable, and generates a combination of the predetermined explanatory variable and the predetermined objective variable as learning data for training a decision tree model.

摘要： The disclosure provides an additional learning device, an additional learning method, and an additional learning program . The additional learning device includes: an acquisition unit (12) acquires information based on data observed in a control object which is controlled by an instruction in accordance with an output from a previously learned model outputting an objective variable with respect to an explanatory variable. A determination unit (14) determines whether or not the explanatory variable corresponding to the information acquired by the acquisition unit (12) exists as learning data of the model, that is, whether or not the explanatory variable is unknown. When the explanatory variable is determined to be unknown by the determination unit (14), an additional learning unit (16) acquires the objective variable corresponding to the unknown explanatory variable, correlates the unknown explanatory variable and the acquired objective variable, and additionally learns the model. The model is updated with regard to unknown disturbance events without requiring manpower.
