应急疏散策略是应对地下商场突发灾害的主要方法之一。针对地下商场的火灾情

Emergency evacuation strategy is one of the main methods to deal with the underground mall sudden disasters. For the case of a fire underground mall, using the principle of system dynamics analysis evacuation characteristics. The emergency evacuation process into contact with each other, while the presence of four subsystems, namely the mobilization of emergency evacuation, evacuation command guidance, evacuations and evacuation ambulance subsystems. Vensim constructed using causal loop diagrams and subsystems and the entire staff of the emergency evacuation system of emergency evacuation SD model and simulation. The results showed that: the effect of the mobilization of emergency evacuation, affect the number of command guidance and ambulance personnel who number in the whole of the pre-emergency evacuation process of evacuation effect is more obvious. Propose appropriate emergency evacuation strategy based on simulation results.

Emergency evacuation strategy is one of the main methods to deal with sudden disasters in underground shopping malls. In view of the fire situation of underground shopping malls, the principle of system dynamics is used to analyze the evacuation characteristics of personnel. The emergency evacuation process is divided into four subsystems that are related to each other and exist at the same time, namely, emergency evacuation mobilization, evacuation command guidance, evacuation operation and evacuation rescue subsystem. The causality map of each subsystem and the whole emergency evacuation system and the SD model of personnel emergency evacuation were constructed and simulation experiments were carried out by Vensim. The experimental results show that the effect of emergency evacuation mobilization, the number of command guides and the number of rescue personnel have obvious effect on the evacuation effect in the early stage of the whole emergency evacuation process. According to the simulation results, the corresponding emergency evacuation strategy is proposed.

Emergency evacuation strategy is one of the main methods to deal with sudden disasters in underground shopping malls. Aiming at the fire situation of underground shopping mall, the characteristics of evacuation are analyzed by using the principle of system dynamics. The process of emergency evacuation is divided into four subsystems, namely, emergency evacuation mobilization, evacuation command and guidance, evacuation action and evacuation rescue subsystem. Vensim is used to construct the causality diagram of each subsystem and the whole emergency evacuation system and the SD model of personnel emergency evacuation. The experimental results show that the effect of emergency evacuation mobilization, the number of commanders and rescuers have a significant impact on the evacuation effect in the early stage of the whole emergency evacuation process. According to the simulation results, the corresponding emergency evacuation strategy is proposed.<br>
