摘要： A gas amount prediction method predicts an amount of gas generated in a factory, and includes a generation amount calculation step of calculating a generation amount of actually usable gas by using a learning model that has learned a relationship between a generation amount of the gas and a use amount of the gas in past operation data.

摘要： A decarburization end point determination method includes: estimating the carbon concentration and oxygen concentration of the molten steel and carbon dioxide gas concentration of exhaust gas in the vacuum chamber by using measurement values of the carbon concentration and the oxygen concentration of the molten steel, a measurement value of internal pressure of the vacuum chamber, and a model formula; correcting a parameter included in the model formula to reduce at least one of a difference between an estimate value and a measurement value of the oxygen concentration and a difference between an estimate value and a measurement value of the carbon dioxide gas concentration of the exhaust gas; estimating the carbon concentration of the molten steel by using the model formula in which the parameter is corrected; and determining timing when an estimate value reaches a target value as the completion time point of the vacuum decarburization treatment.

摘要： A guidance device for selecting a safety factory according to the present invention is a guidance device that selects a safety factory, which is an operating factory at the time of a power failure, and presents a safety operation plan for a plurality of factories in a power system. The guidance device includes a presentation unit that calculates a combination of an operating factory and a non-operating factory within a predetermined period from a planned value of power demand-supply of a factory so that a power consumption amount of the factory satisfies a predetermined condition and that presents information on the calculated combination.
