In order to overcome the shortcomings or insufficiency of analysis methods individually based on graph theory or quantitative analysis method, semi-quantitative fault diagnosis method based on graph theory and fuzzy theory combined with functional fault analysis (FFA) theories and Failure Mode and Effects Analysis(FMEA) is studied. And a multi-hierarchical functional directed graph modeling method is proposed for aircraft system fault diagnosis. Nacelle Anti-Ice subsystem of an aero engine is taken as a specific application to present the detailed MHFDG modeling method.
Keywords:System modeling; Aircraft system; Fault diagnosis; Graph theory; Function Fault Analysis
