Title:
需要予測装置及び需要予測方法
Document Type and Number:
Japanese Patent JP5129799
Kind Code:
B2
Abstract:
The present invention provides a demand prediction device and a demand prediction method capable of performing demand prediction with higher accuracy. A demand prediction server 10 includes a data acquisition unit 1 for acquiring estimated population information that indicates population estimated in a predetermined area, a spatial weighing unit 3 for acquiring relative distance information that indicates a distance between a position of a prediction reference area included in the predetermined area and a position of a prediction target area for which the number of demands is to be predicted with the prediction reference area as a reference, and a regression analysis unit 4 and a demand prediction unit 5 for, by performing regression analysis using the estimated population information acquired by the data acquisition unit 1 and a residual based on the relative distance information acquired by the spatial weighing unit 3, predicting the number of demands in the prediction target area.
