<p>PURPOSE:To reduce corrected value calculating man-hour and to make sales amount prediction highly accurate by fetching the actual result value showing an abnormal value from an input device and automatically calculating the sales amount as the corrected value of the abnormal value. CONSTITUTION:A planner fetches data for prediction of the sales plan object product set by the interactive form with a computer 1, referring to displayed data setting and supporting information for prediction. Next, supporting information for designating an actual result value affected extremely by a sudden factor in sales actual result data is displayed on an output device 2. Referring to the displayed abnormal actual result value designating and supporting information, the planner fetches the abnormal actual result value in the data for prediction which is designated by the interactive form with the computer 1. Next, the corrected value of the abnormal actual result value is calculated. Further, by using sales actual result data, the predicted value of sales amount at a prediction object time is calculated. Referring to the displayed predicted value correcting and supporting information, the planner fetches the corrected value of the predicted value corrected by the interactive form with the computer 1.</p> |
