Patent ID: 8560374

Claim:
A computer-implemented method to determine daily weight values for use in forecasting daily demand for a product during a forecast week, said method comprising the steps of: storing within a database, implemented within a data warehouse, historical demand data for said product; retrieving from said data warehouse, by a computer in communication with said data warehouse, historical daily demand data for said product for a period of at least one week immediately preceding said forecast week; for each day of said at least one immediately preceding week, calculating, by said computer, a daily weight value for said product by dividing the historical daily demand for a corresponding day of said at least one immediately preceding week by a total of said historical daily demands for all seven days of said at least one immediately preceding week; retrieving from said data warehouse historical, by said computer, daily demand data for said product for a period of at least one week one year prior to said forecast week; for each day of said at least one year prior week, calculating, by said computer, a daily weight value for said product by dividing the historical daily demand for a corresponding day of said at least one year prior week by a total of said historical daily demands for all seven days of said at least one year prior week; analyzing, by said computer, said historical demand data to determine weekly weighting values to be applied to said corresponding daily weight values for said at least one immediately preceding week and said at least one year prior week; and blending, by said computer, said corresponding daily weight values for said at least one immediately preceding week, said corresponding daily weight values for said at least one year prior week, and said weekly weighting values to determine a daily weight value for use in forecasting daily demand for a product.
