Monitoring a demand forecasting process

摘要

Systems and methods of monitoring a demand forecasting process are described. In accordance with a demand forecasting monitoring method, a measure of forecast error variability is computed at each period of a selected time frame, and an indicator of forecast bias is computed at a given period within the selected time frame based on forecast error consistency over periods of the selected time frame prior to the given period. A computer program for implementing the demand forecasting monitoring method is described. A system for monitoring a demand forecasting process that includes a graphical user interface configured to display a measure of standard deviation of percent forecast error at each period of a selected time frame also is described.
