DEMAND-PREDICTION DEVICE, PROGRAM, AND RECORDING MEDIUM

Provided with an input device (3) that, when the demand for a plurality of time periods in one day is predicted in the prediction of demand in future time sequence data, inputs as a portion of the input data for the demand prediction of a demand prediction time period the input data for the demand prediction of the aforementioned demand prediction time period and prediction results of the demand of a prescribed time period that is before the aforementioned demand prediction time period; and a demand-prediction calculation unit (5) that calculates the prediction value of the demand in the aforementioned demand prediction time period using input results from the aforementioned input device.
