The document summarizes a collaboration between the University of Southern Maine's Maine Center for Business and Economic Research (MCBER) and Hannaford Bros. Co. to develop an automated statistical forecasting system. MCBER helped Hannaford improve the accuracy of its weekly sales forecasts for over 6,000 store-level product categories. The system reduced Hannaford's average weekly forecasting error by over 50% and estimated annual savings of $170 million by reducing overestimation and underestimation costs.
