Demand forecasting support program demand forecasting support system, and demand forecasting support method

摘要

PROBLEM TO BE SOLVED: To improve accuracy in demand prediction by efficiently grouping actual result data to be referred to in a system for supporting product demand prediction.;SOLUTION: An initial group setting program 20 selects group candidates according to kinds and displays the actual result data of the candidates on an initial group setting screen 10. Further, an average absolute error rate is computed in association with a user adding items to the groups, and the result is displayed. An analysis object product group setting program 21 displays the sales result of analysis object products on an analysis object product group setting screen 11. Further, an average absolute error rate is computed in association with the movement of groups to which the analysis object products belong to, and the result is displayed. A group result evaluation program 22 computes a score from the error rate of a prediction result and a result value of every group concerning items and years and months in association with the user inputting optional items and years and months on a group result evaluation screen 12. The names of the items belonging to the groups are also displayed.;COPYRIGHT: (C)2007,JPO&INPIT
