Abstract: The fire characteristics of emporium were analyzed. The fire safety analysis of emporium was conducted. A typical emporium in Maoming, Guangdong is selected as the prototype to build evacuation model based on Dijkstra algorithm. The evacuation time was calculated. The factors affecting the evacuation were analyzed. In points ofthe layout and management, evacuation guidance, and fire emergency drill of the emporium, the fire emergency management strategy was optimized. It is found that the shortest evacuation time of the three floors is 83.1, 85.5, 145.6 s respectively, and the example area evacuation time is reduced by 8.9 s after taking optimization measures, the optimization rate was 18.6%. This study is meaningful to improve the emergency handling capacity of emporiums and enhance public safety environment.

Key words: emporium fire, emergency management, Dijkstra algorithm, evacuation time
