摘　　要：突发事件人群疏散模型是制定安全、高效疏散策略的分析基础。本文将粒子群算法和模拟退火算法相结合,提出了SAPSO疏散模型,并针对疏散不同阶段特征,对模型参数进行了动态调整。此外,针对传统PSO模型的不足进行了改进,充分考虑了障碍物对个体疏散路径选择的影响,同时分析了出口位置变化导致的疏散差异。最后基于典型建筑物室内场景,对应急疏散过程进行了仿真分析,仿真结果验证了SAPSO模型的有效性。Pedestrian evacuation model is the basis of the formulation of safe and efficient evacuation plan, combining particle swarm optimization （PSO） algorithm with simulated annealing （SA） algorithm, this paper conducts the research of the pedestrian evacuation model in emergency, and through the analysis of the population characteristics in different evacuation stages, a new crowd evacuation model with dynamic parameters based on PSO and SA is proposed. Furthermore, the shortcomings of the previous model are improved, and the impact of obstacles to the evacuation route selection is fully considered, meanwhile, the differences in the location of exit are analyzed. Finally, the effectiveness of the proposed model is verified by a crowd evacuation simulation in a building.
