Abstract

In case of a fire, it is the primary task of fire emergency response to safely and quickly evacuate indoor personnel to a safe area. Aiming at the characteristics of fire development and evacuation of multi-storey buildings, a layered evacuation strategy based on entropy is proposed for multi-storey buildings. With the help of PyroSim software to simulate the fire combustion process, the influence of the spread state of fire smoke on the selection of escape path exit in the building was analysed. Using AnyLogic, an agent modeling and simulation platform, making hybrid modelling of agents, discrete-event simulations and simulation of fire spread using system dynamics. Considering various influencing factors such as the gender, age, evacuation speed, and spatial distribution of the evacuated population, a simulation model close to the real layered evacuation process of personnel was established. The entropy optimization path selection strategy was used to make full use of various exits. The simulation results show that the fire smoke has different effects on different floors; By comparing the two plans, Plan B is obviously better than Plan A, so as to improve the effective occupation time of exit; The stratified evacuation strategy under the influence of fire smoke can reduce the evacuation time, improve the evacuation efficiency, and effectively ensure the safety of evacuees.
