Abstract: In order to address emergency evacuation of personnel in airport terminals in the event of violent terrorist attacks, relationship between various influencing factors was analyzed by usingISM method and decision-making trial and evaluation laboratory (DEMATEL). And key factors affecting personnel evacuation ability were screened out. Then, classification standards of warning levels for emergency evacuation were put forward according to relevant standards, regulations, severity and controllability of attacks and emergency evacuation area. The results show that building structure, safety facilities, violent terrorist attacks, age, emergency preparedness, evacuation channel, environment familiarity and on-site status have great influence on other factors of evacuation capacity. Those that are greatly affected by other factors are mainly speed, evacuation guidance, emergency rescue, crowd's angle, evacuation distance, safety facilities, violent terrorist attacks and evacuation channels. The key influencing factors are evacuation guidance, speed, emergency rescue, safety facilities, violent and terrorist attacks, building structure, crowd's angle and evacuation distance. And attribution causes that affect evacuation ability rank in order of importance as building structure, age, familiarity with environment, safety facilities, site condition, gender, violent terrorist attacks and emergency preparedness.

Key words: violent terrorist attacks, terminal, evacuation capability, evacuation warning, interpretative structural modeling(ISM) method
