An evolvable tri-reasoner IVHM system

Meeting the challenges of decreasing operational costs and increasing operational readiness for future aircraft will require a systemic approach to integrated vehicle health management (IVHM). Realizing such an approach will involve synergistic deployments of component health monitoring technologies, as well as integrated, model-based reasoning capabilities for the interpretation of the monitor outputs. Further, it will involve the introduction of learning technologies to support the continuous improvement of the knowledge enabling these reasoning capabilities. Finally, it will involve organizing these elements into an architecture that governs integration and interoperation-within the VHM system, between its on-board elements and their ground-based support functions, and between the VHM system and external maintenance and operations functions. We present and discuss the architecture for an evolvable tri-reasoner integrated VHM system, its particular elements and their interrelationships.
