Research on accident process meta-modeling based on SysML

Based on the situation that faults cause hazard in complex equipment system, an accident process meta-model is proposed based on the meta-model theory. The meta-model of the accident process is explained from the implementation view. Four modeling views and the modeling steps of the accident process meta-model are presented based on SysML. Eventually, the method is applied in a case study of Servo of main rotor in flight control system. The result shows that accident path can be found through meta-modeling of accident process.
