A computerized system and method for supply chain order aids a manufacturer's production control departments in setting manufacturer production schedules and purchase schedules. A computerized production control system in communication with a computerized ordering system presents a consistent demand level to reduce changes to the purchase and delivery schedules. A next day production schedule is adjusted to keep total demand within the supply chain constant. At the end of a production day, actual production is compared to an original production plan to calculate an adjustment value. The adjustment value is applied to the next day's production schedule to revise the production schedule. If the actual number of units produced is lower than the planned number of units, units are added to the next day's purchase schedule to determine a revised purchase schedule. Other adjustments may be made if the actual number of units produced exceeds the planned number of units.
