INTERACTIVE SYMBOLIC SIMULATOR FOR RAPID ANALYSIS COMMUNICATIONS SYSTEMS

PREDICTION SYSTEMS, INC. (PSI) HAS INTRODUCED THE CONCEPT OF SYMBOLIC MODELING WITH ITS GENERAL SIMULATION SYSTEM (GSS) TO PROVIDE COMMUNICATIONS SYSTEMS ENGINEERS WITH THE ABILITY TO RAPIDLY BUILD COMPLEX MODELS, RUN SIMULATIONS, AND GET RESULTS VERY QUICKLY. IN THIS PROJECT, PSI IS PROPOSING TO EXTEND THIS CONCEPT TO PROVIDE INTERACTIVE SYMBOLIC SIMULATION, A CONCEPT WHICH WILL ALLOW COMMUNICATIONS ENGINEERS TO INTERACT WITH THE SIMULATION, MANIPULATING SYMBOLIC MODELS AND GETTING SYMBOLIC MEASURES OF PERFORMANCE DIRECTLY, IN REAL TIME. TO SUPPORT THE KINDS OF ANALYSES REQUIRED FOR DESIGN, TEST, AND EVALUATION OF ARMY GROUND COMMUNICATIONS, THE ANALYST MUST BE ABLE TO PAN AND ZOOM OVER MILITARY MAPS. TO ACCOMPLISH THIS, PSI IS PROPOSING TO INTEGRATE ITS HIERARCHICAL TERRAIN DATA BASE, WHICH SUPPORTS FAST PROPAGATION PREDICTIONS, WITH THE LARGEST GRAPHICS TECHNOLOGY USING THE GSS RUN TIME GRAPHICS SUPPORT OPTION. IN PHASE I, PSI WILL DEMONSTRATE HOW INTERACTIVE SYMBOLIC SIMULATION, SUPPORTED BY DETAILED ENGINEERING MODELS, CAN BE USED TO OBTAIN COMMUNICATIONS SYSTEM PERFORMANCE MEASURES IN REAL TIME. THE OBJECTIVE IS TO SHOW HOW COMPLEX ANALYSES CAN BE PERFORMED VERY QUICKLY WITH A MINIMUM OF SCARCE ENGINEERING RESOURCES.
