Backup control system (BCS) for optimizing utilization of multiple fabrication facilities

A method for operating a plurality of fabrication facilities comprising:

• providing a plurality of fabrication facilities, each fabrication facility being controlled by a separate corresponding manufacturing execution system;
• providing within each of the plurality of fabrication facilities, and connected with each of the separate corresponding manufacturing execution systems, a corresponding plurality of backup control systems, each backup control system being connected with the remaining backup control systems within the remaining fabrication facilities within the plurality of fabrication facilities, each backup control system being programmed to forward a request for fabrication in a remote fabrication facility within the plurality of fabrication facilities and receive a request for fabrication from a remote fabrication facility within the plurality of fabrication facilities;
• and
• initiating through a backup control system within a fabrication facility within the plurality of fabrication facilities a request for fabrication within a remote fabrication facility within the plurality of fabrication facilities.
