  • Determining scheduling priority using queue time optimization
    Patent number: 7623936
    Abstract: A method for determining priority of a selected workpiece in a process flow including a plurality of operations includes providing an objective function relating manufacturing losses to workpiece priority for the operations in the process flow. The objective function is solved to generate priority metrics for at least a subset of the operations remaining for the selected workpiece to allow completion of the selected workpiece in the process flow by a target completion due time.
    Type: Grant

  • Determining scheduling priority using fabrication simulation
    Patent number: 7460920
    Abstract: A method for processing workpieces in a process flow including a plurality of operations includes employing a fabrication simulation model of the process flow to determine an estimated completion time for a selected workpiece. The fabrication simulation model simulates the processing of the selected workpiece and other workpieces in the process flow through the plurality of operations. The priority of the selected workpiece is adjusted based on a comparison between a target completion time for the selected workpiece and the estimated completion time.
