Abstract: The accident-process oriented safety simulation method was proposed to ensure the safety of high risk systems, as well as explore the movement during the accident evolution and emergency treatment. The modeling and simulation method was designed upon the principle of finite state machine and the technology of Stateflow. By this method, the modeling and simulation of process logic and continues mechanism in hybrid system can be achieved. Then the simulation result can reflect the system characteristic of state transforming and man-machine communicating, and the mechanism in the accident process, accordingly, the quantitative support can be provided for the emergency treatment decision-making. Finally, the model design and simulation experiment for the typical accident process in some product were implemented, and the validity and rationality of this proposed method were validated by the result.
