  • Patent number: 7653451
    Abstract: Disclosed is a method of controlling a manufacturing system. The invention automatically monitors current levels of partially completed products waiting to be processed by a tool (or group of tools) and determines whether the current levels exceed a predetermined limit. If the current levels do exceed the predetermined limit, the invention performs an optimization process. However, if the current levels do not exceed the predetermined limit, the invention performs a dispatching process. In this dispatching process, the invention automatically projects future levels of partially completed products that will be supplied to the tool to identify a future work-in-process (WIP) bubble. The WIP bubble occurs when larger than normal amounts of partially completed products are supplied to the tool. The invention automatically adjusts the operating parameters of the tool based upon both the current levels and the future levels.

  • Patent number: 7239930
    Abstract: The present invention provides a method, system, and computer program product for improved flow of development lots in a manufacturing facility. A method in accordance to one embodiment of the present invention comprises: establishing at least one target for processing of a set of development lots in the manufacturing facility; monitoring a progress of the set of development lots in the manufacturing facility; comparing the progress of the set of development lots against the at least one target; establishing at least one suggested action for the set of development lots if the progress of the set of development lots deviates from the at least one target; and deciding which development lots in the set of development lots to assign to at least one tool in the manufacturing facility, wherein the at least one suggested action is incorporated into the assignment decision.

  • Patent number: 7043322
    Abstract: A system and method for utilizing computer-implementable decision support systems to determine factory schedules. Methodologies associated with the invention include advanced planning systems, optimization and heuristic based algorithms, constraint-based programming, and simulation. The method may iteratively assign lots to non-full batches based on comparison of the resulting impact to mean flow time with the continuously approximated cost per batch. Once lots have been assigned to batches, potential interchanges of lots among batches are explored. If the variable cost per batch changes from one interchange to the next, the method may backtrack and attempt to re-allocate lots to batches based on the increased cost per batch.
