考虑灾民类型多模式协同应急疏散调度研究

Research on multi-mode cooperative emergency evacuation scheduling considering types of disaster victims

为提高城市在突发事件发生后大规模人员疏散效率,减少人员伤亡和财产损失,考虑灾民行动力的异质性和不同时间窗限制,提出多模式协同疏散策略;构建以总疏散时间和总损失最小为目标的应急疏散调度优化模型;利用蚁群算法求解,结合算例分析验证模型的合理性和算法的可行性。研究结果表明:通过算法求解可使模型迅速收敛,且模型具有一定的稳定性,对于不同类型灾民采用多模式协同疏散更符合实际情况,可以形成高效的应急疏散调度方案。

In order to improve efficiency of large-scale evacuation of people in cities after emergencies,and to reduce casualties and property losses,a multi-mode coordinated evacuation strategy was proposed considering the heterogeneity of disaster victims'mobility and different time window restrictions.Then,an optimized emergency evacuation dispatching model was developed with the goal of minimizing total evacuation time and total loss.Finally,ant colony algorithm was used to solve the problem,and the model's rationality and the algorithm's feasibility were verified based on real case analysis.The results show that the model can converge quickly through algorithm solving,and the model has a certain degree of stability.Moreover,adoption of multi-mode cooperative evacuation for different types of victims is more consistent with actual situation and can form an efficient emergency evacuation scheduling plan.
