Estimating the term…
A method and system that creates a rule-based Operation Job Supervisor System (OJS) or decision engine to automate and control Fab production for the optimum movement of wafer boxes through the Fab. It is integrated with current manufacturing control systems and a cooperative model between the dispatching and scheduling functions. This easy-to-maintain system architecture makes use of a dynamic evaluation formula and sub-formula that can handle exception cases and consider wafer box physical position concurrently. Because the decision engine is rule based, rule can be revised without need for re-compiling and shutting down the system. New patterns are learned by the system automatically when variables and parameters in the formulas are revised.
