INTEGRATED DEMAND FORECASTING APPARATUS, INTEGRATED DEMAND FORECASTING METHOD AND INTEGRATED DEMAND FORECASTING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an integrated demand forecasting apparatus, an integrated demand forecasting method and an integrated demand forecasting program which can perform more accurate demand forecasting for a plurality of different forecasting periods.;SOLUTION: A forecast value calculation part 2 constructs a plurality of demand forecast models from a sales volume and calculates a forecasted sales volume (predicted demand volume) in each constructed forecast model. A forecast value error calculation part 4 calculates a forecast error from the sales volume and the forecasted sales volume. An integrated demand forecast blend ratio calculation part 6 integrates these processed forecast errors and weight, integrates forecast errors from short-term and long-term view points, and calculates a blend ratio of each forecasting technique so that the integrated forecast error is minimized. A demand forecast result output part 9 calculates forecast values for a forecast period using the forecasting technique and calculates a forecasted sales volume in a final forecast period by integrating the forecast value and the blend ratio.;COPYRIGHT: (C)2009,JPO&INPIT
