Due　to　the　increasing　frequency　of　terrorist　attacks　all　over　the　world,　we　designed　an　emergency　evacuation　model　under　the　situation　of　the　terrorist　attacks.　This　model　uses　the　Ant　Colony　Optimization　(ACO)　as　a　macro　solution,　the　Cellular　Automata　(CA)　as　a　micro-control　method,　and　the　Queuing　Theory　Model　(QTM)　to　solve　the　queuing　problem　of　escape　exits.　Based　on　the　model　we　built,　the　optimized　evacuation　plan　under　different　conditions　were　obtained.
