Patent number: 7565218Abstract: A system and method are disclosed for prioritizing a plurality of lots in a manufacturing process. Portions of a priority for each lot are created. The portions are combined to form a unique range priority for each lot. The range priorities may be used to equitable compare all of the active lots in a fabrication facility. The system and method may be implemented as part of a range management system.Type: GrantFiled: March 30, 2006Date of Patent: July 21, 2009Assignee: International Business Machines CorporationInventors: Richard G.

Patent number: 7480538Abstract: Methods, systems, and computer program products for managing movement of work-in-process materials between processing units in an automated manufacturing environment are provided. A system includes a host system in communication with a work-in-process (WIP) material lot. The system also includes an application executing on the host. The application implements a method that includes tracking a position of the WIP material lot, receiving a list of the processing units designated to be inoperative during a down time, and receiving a start time and a duration of the down time. The method also includes determining a maximum dwell time for each of the designated processing units and scheduling movement of the WIP material lot during an interim between a current time and the start time of the down time based on current position of the work-in-process material lot, the current time, the start time and duration of the down time, and the maximum dwell time.Type: GrantFiled: November 14, 2007Date of Patent: January 20, 2009Assignee: International Business Machines CorporationInventors: Richard P. Volant, Bradley P. Jones, Sameer T. Shikalgar, Michael J. Toner, Yutong Wu

Patent number: 7477957Abstract: A system and method for driving new technology WIP at a controlled speed side-by-side with production WIP using a common range management infrastructure. The system and method allow new technology WIP and production WIP to be driven together in the same fabricator with the same degree of speed and predictability. The system and method may include at least one device configured to create a target based on a sum of active WIP targets for at least one route, find all lots of active WIP on the at least one route, tag each of the lots until a first occurrence of a sum of WIP of the tagged lots exceeds or equals the target, and assign a priority to each of the tagged lots based on a predetermined criteria.Type: GrantFiled: March 30, 2006Date of Patent: January 13, 2009Assignee: International Business Machines CorporationInventors: Richard G. Burda, Aseem K. Joshi, Sameer T. Shikalgar, Susan Kangas van Oss, Patrick R. Varekamp

Publication number: 20080167743Abstract: Methods, systems, and computer program products for managing movement of work-in-process materials (WIPs) between processing units are provided. A system includes a host system and an application executing thereon. The application implements a method that includes receiving a list of WIP lots, and indexing a list of routes with raw process time by process steps and with safe holding points. The method also includes indexing a scheduled start time of shutdown for the process units and calculating transport time for moving each of the lots to the next nearest safe holding point in the route. For each lot, the method includes determining whether the lot is at a safe holding point, and assigning a dispatch priority to the lot if it is not at the safe holding point. The method further includes sending a list of assigned dispatch priorities to a dispatcher for transporting the lots to corresponding safe holding points prior to initiating the shutdown.Type: ApplicationFiled: October 8, 2007Publication date: July 10, 2008Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Richard P.
