In order to predict demand, in a demand prediction computing unit (100) a dealer demand prediction computing unit (200) predicts a demand for a dealer, a corporation demand prediction computing unit (300) predicts a demand for a corporation, and a totaling unit (400) totals the predicted demand for the dealer and the predicted demand for the corporation, predicting thereby an aggregate demand. The dealer demand prediction computing unit (200) takes the attribute of the dealer into account and predicts the demand, and the corporation demand prediction computing unit (300) takes the attribute of the corporation into account and predicts the demand. In this manner the attribute of a demander (customer) is taken into account and demand is predicted, and therefore the prediction accuracy is improved. |
