  • Patent number: 10732913
    Abstract: A system and method is used to manage scheduling of a plurality of print jobs in a multi-site print shop environment. The multi-site environment includes a plurality of print shops each having resources and equipment to complete at least one type of print job. Also included is a multi-site scheduler configuration arranged to assign and schedule print jobs to one of a home shop and a non-home shop. The assigning and scheduling is based on a fastest completion time, wherein a completion time of a print job in a home shop is defined as the actual time taken to complete the print job and a completion time of a print job in a non-home shop is defined as the actual time taken to complete the print job and a transportation delay.

  • Patent number: 9423989
    Abstract: A method and system for processing jobs in a print shop is provided. The print shop includes at least two autonomous cells, and each autonomous cell includes a resource for performing an operation relative to at least one of the jobs. In one approach, the number of jobs requiring an operation at each one of the two autonomous cells is monitored. When the number of jobs requiring at least one operation at each one of the two autonomous cells exceeds a selected number, a reconfiguration mode is simulated for at least one of the two autonomous cells to obtain a reconfiguration desirability value. The at least one of the two autonomous cells is reconfigured when the reconfiguration desirability value differs from a selected reference value.

  • Patent number: 9396445
    Abstract: A control system usable in a print shop where print jobs are processed with at least one print shop related resource is provided. The at least one print shop related resource is operated over multiple discrete time intervals such that production related data is generated for each one of the multiple discrete time intervals. The production related data generated during each one of the multiple discrete intervals is collected and stored in memory. The control system includes a controller and a program. The program operates with the controller to calculate at least one performance measure value from the stored production related data, and to determine, with the at least one calculated performance measure value, whether any further collection of production related data is required.
