Abstract
A multi-facility control system includes a controller and attendant memory. Stored in the memory are a plurality of rules, each of which includes a conditional portion representative of a condition to be examined and a conclusive portion describing action to be taken when the condition is satisfied. Also stored in memory is the current status of each facility, information representative of the tasks to be performed by the facilities and updated status information resulting from the satisfaction of the conditional parts of the rules. The controller monitors the status of the facilities and compares monitored status information with the conditional parts of the rules stored in memory. When rule conditions are satisfied, control instructions are generated which are employed to produce command signals that are coupled to the respective facilities for controlling the operations thereof.
