With the development of airborne system towards integration, complexity, and intellectualization, the function logic, architecture design, and fault-tolerant design of the system become more and more complex. The traditional safety and reliability analytical methods based on artificial deductive reasoning cannot meet the current requirements. The model-driven design method is becoming an important technique for the safety and reliability design of complex systems. Especially in recent years, model-based system engineering technology has developed rapidly and has been widely used and recognized in domestic and foreign aviation enterprises, providing favorable conditions for the further development of model-based system safety and reliability design technology. This paper mainly introduces the research progress of model-based safety and reliability analysis technology of complex system at home and abroad analyzing the future development direction and trend of this technology, providing references for system safety and reliability analysis of the material.
