Abstract

In order to provide the optimal evacuation path for people and improve the emergency response capability, CEPO method based on RSA is proposed in this paper. Fire Dynamics Simulator(FDS) was used to obtain fire spreading parameters and simulate the fire spreading process, then the CEPO based on the RSA was used to optimize the evacuation path with fire real-time spreading, and Dynamic Path Optimization (DPO) method was taken to verify the effectiveness of the CEPO method. By simulating the high-rise fire evacuation process, the results show that t he total evacuation time of the CEPO method is about 8% shorter than the traditional DPO method. The total number of people who cannot successfully evacuate the DPO method is 270% of the CEPO method. The CEPO method can perform one off-line optimization to obtain the actual optimal fire evacuation path, avoiding the unreasonable phenomenon of the roundabout, and significantly improving the number of people successfully evacuated. © 2019 China Safety Science Journal
