Dynamic State-Based FM Design and Analysis Tool

Odyssey proposes a new fault management planning and design tool and methodology that uses state-based simulations with programmable dynamic state definitions to provide early assessments of fault management system scope and cost. The tool will utilize models developed in SysML to capture system characteristics and relationships between system components as well as mapping of functionality to requirements and mission objectives, and a probabilistic state-based simulation to determine requirements compliance, fault probabilities, and the number of fault paths in the system. The tool will provide useful visualization of the FM design and fault paths, including the dynamic aspect of the system, as well as visual representations of system complexity. In addition, the tool will provide automated means to estimate the complexity of the FM design based on system characteristics and simulation results. The tool will provide engineers and managers with the ability to scope the fault management (FM) effort from requirements development through verification at a point early in the design process. Phase I will focus on proof of concept and demonstration of key aspects of the tool, with full tool development and scaling to complex systems in Phase II.
