A time-phased forecasting and replenishment system (20) for retail
organizations which can be used for inventory management and financial
management. One or more computers (28) create time-phased plans for one
or more retail facilities, such as various types of retail stores (23)
and/or various types of suppliers (24). The system calculates projected
sales for each product at each facility and calculates projected
replenishment shipments between facilities and suppliers a specified
number of weeks into the future. The calculated forecasts and
replenishments are done in ways that account for the unique needs of
retail organizations, and allow efficient processing and storage of the
large data volumes typical in many retail organizations.
