IGF::OT::IGF GLOBAL TECHNOLOGY CONNECTION, INC. IN CONJUNCTION WITH ITS PARTNER, VANDERBILT UNIVERSITY, IS PROPOSING TO BUILD A FUSION-ENHANCED VEHICLE DIAGNOSTICS SYSTEM (FVDS) FRAMEWORK TO COMBINE VARIOUS INFORMATION TO HELP MAKE GO/NO-GO DECISIONS FROM A SAFETY POINT OF VIEW. SPECIFICALLY SINGLE VEHICLE WILL BE PURSUED BY LOOKING AT EACH AIRCRAFT AS A SINGLE ENTITY. THE SYSTEM WILL ENSURE THAT THE AIRCRAFT WILL MAKE THE NEXT MAINTENANCE INTERVAL BY CATCHING ERRORS IN THE SHOP AND/OR DETECTING EMERGING PROBLEMS TO MAINTAIN VEHICLE SAFETY BETWEEN MAJOR INSPECTION INTERVALS WITH AN EMPHASIS ON THE SUBSYSTEMS OF AIRFRAME, AVIONICS, AND PROPULSION. THE SYSTEM WILL PROVIDE CONDITION INDICATORS, USING MODEL-BASED OR DATA-DRIVEN APPROACHES, FROM A SUBSYSTEMS' OR COMPONENTS' POINT OF VIEW, AND THESE WILL BE FUSED, USING THE HYBRID MODELING BASED ON BAYESIAN THEORY AND/OR GRAPH THEORY, TO PROVIDE OVERALL SAFETY FROM A SYSTEM POINT OF VIEW. FVDS APPROACH CONSISTS OF A MULTI-LEVEL PROCESSING ARCHITECTURE THAT INCLUDES THREE LEVELS OF REASONERS: 1. INDIVIDUAL COMPONENTS AND LINE REPLACEABLE UNITS THAT PROVIDE BIT TEST, SENSOR MEASUREMENTS AND CONTROL COMMANDS TO TRACK THE BEHAVIOR OF THE PARTICULAR COMPONENT, AND REPORT FAULTY AND ABNORMAL CONDITIONS; 2. SUBSYSTEM REASONERS TO MONITOR THE STATE OF HEALTH OF THE AIRFRAME SUBSYSTEM; AND 3. SYSTEM OR VEHICLE LEVEL REASONER TO COMBINE DIAGNOSTIC AND PROGNOSTIC INFORMATION FROM THE INDIVIDUAL SUBSYSTEMS, PUTS THEM ON A TIME LINE, AND ALSO ANALYZES CASCADES OF FAULTS.
