REAL-TIME EXPERT SYSTEMS

THIS PROJECT WILL DEVELOP A GUARANTEED-PERFORMANCE, HARD, REAL-TIME EXPERT SYSTEM FOR THE EVENTUAL SUPPORT OF REAL-TIME MISSION PLANNING AND CONTROL FOR FLIGHT OPERATIONSOF THE SHUTTLE ORBITERS AND OF THE SPACE STATION FREEDOM. THE OBJECTIVES ARE TO DETERMINE THE FEASIBILITY OF USING AN INNOVATIVE SCHEDULER, IN COMBINATION WITH AN APPROXIMATE REASONING TECHNIQUE, AS A MEANS TO SCHEDULE EXPERT-SYSTEM RULE PROCESSING IN A WAY THAT GUARANTEES A HARD, REAL-TIME RESPONSE TIME FROM AN EXPERT SYSTEM; TO DETERMINE WHICH APPROXIMATE REASONING TECHNIQUE--PROGRESSIVE DEEPENING, PROGRESSIVE REASONING, TIME-CONSTRAINED INFERENCE, OR OTHER--IS MOST APPROPRIATE TO USE WITH THE SCHEDULER; AND TO DEVELOP A DESIGN FOR A REAL-TIME PLANNER FOR SHUTTLE ORBITER AND SPACE STATION FREEDOM ORBITAL DOCKING PROCEDURESAS A DOMAIN IN WHICH TO STUDY POSSIBLE PERFORMANCE IMPROVEMENTS. THE PROJECT WILL DETERMINE AN IMPROVED METHODFOR SCHEDULING THE ORDER OF PROCESSING RULES AND FACTS IN RESPONSE TO A REAL-TIME INPUT AND WILL APPLY INNOVATIVE MANAGEMENT OF THE (USUALLY) LIMITED COMPUTING RESOURCES IN EMBEDDED APPLICATIONS.
