Abstract : The Expert System Management System (ESMS) Small Business Innovative Research Contract developed a distributed fault-tolerant expert system shell for multiple expert systems in a multiprocessor environment. The ESMS contained four domain specific expert systems called Manager Expert System, Route Planner Expert System, Weapon Expert System, and Situation Awareness and Display Expert System. The ESMS expert system shell was written in LISP and runs on four Explorer II computers. Each of the expert systems were responsible for their own area of expertise, but each communicated and cooperated with the other experts along with along real-time man-in-the-loop flight simulator. The four expert systems developed were host independent, relocatable, and interruptable when a higher priority task arrived. The ESMS was able to detect network and processor failures, along with being able to reconfigure the system according to the available resources. The system was both event and data driven, and shared global variables. The system was interfaced with a MicroVAX II computer to the MIL-STD-1553 data bus in order to receive waypoints and aircraft data from a real-time man-in-the-loop simulation.
