SYSTEM FOR DYNAMIC INVENTORY CONTROL
First Claim
1. A production management system for dynamically controlling inventory to prevent overstock and stockout, the production management system comprising:
- a production planning module including components containing data of demand forecast, and customer order; and
a dynamic inventory control module including a dynamic inventory control simulation module and an inventory management system, wherein the dynamic inventory control simulation module is configured to adjust a target inventory if a current inventory is beyond a threshold multiplied by the target inventory for M number of review cycles, wherein M is an integer.

Abstract
A production management system is configured to dynamically controlling inventory of a semiconductor product to prevent overstock and stockout. The production management system includes a production planning module including components containing data of demand forecast, and customer order. The production management system further includes a dynamic inventory control module including a dynamic inventory control simulation module and an inventory management system, wherein the dynamic inventory control simulation module is configured to adjust a target inventory if a current inventory is beyond a threshold multiplied by the target inventory for M number of review cycles.

8. A production management system for dynamically controlling inventory to prevent overstock and stockout, the production management system comprising:
-
a production planning module, wherein the production planning module is configured to determine a demand curve for at least one product; and a dynamic inventory control module connected to the product planning module, wherein the dynamic inventory control module includes; a dynamic inventory control simulation module configured to generate instructions for altering a production process based on the demand curve; and an inventory management system configured to store real inventory data and real shipping data. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A production management system for dynamically controlling inventory of a semiconductor product to prevent overstock and stockout, the production management system comprising:
-
a production planning module comprising a first processor configured to establish an initial forecast of target inventory, wafer starts, inventory, shipment, cycle time, upper inventory threshold, and lower inventory threshold for a product including components containing data of demand forecast, and customer order; and a dynamic inventory control module comprising a second processor configured to; review and compare real inventory and target inventory on a periodic basis; reduce the forecast of target inventory, responsive to a determination that the real inventory exceeds the upper inventory threshold for a number of consecutive review periods, and repeat the step of reviewing and comparing real inventory and target inventory data and the step of reducing the forecast of target inventory, responsive to a determination that an end of product life cycle has not been reached. - View Dependent Claims (19, 20)
