The invention relates to the technical field of evacuation path optimization, and particularly discloses a passenger emergency evacuation path optimization management method and system based on dynamic flow allocation, and the method comprises the following steps: obtaining a path set of a target region; obtaining the total investment and the investment distribution of each road section in the path set, and calculating the investment budget of each road section based on the total investment and the investment distribution; constructing a double-layer calculation model; and calculating the maximum criticality minimum value of the road section and the actual investment amount based on the investment amount and the double-layer calculation model. According to the method, the two-layer calculation model is constructed, the sensitivity algorithm is utilized to calculate the actual investment cost of the road section and the minimum value of the maximum criticality, the most important road section in the emergency evacuation path is determined, and the actual investment amount of the road section is obtained, so that the reliability of the road section is improved with the minimum investment cost; the weakest link of the road network system is enhanced, and the emergency evacuation path network system of the ro-ro passenger ship passengers is effectively optimized.
本发明涉及疏散路径优化技术领域,具体公开了一种基于动态配流的旅客应急疏散路径优化管理方法及系统,包括以下步骤:获取目标区域的路径集合;获取路径集合中各路段的投资总额和投资分配,基于投资总额和投资分配计算各路段的投资预算;构建双层计算模型;基于投资金额和双层计算模型计算路段的最大关键度最小值以及实际投资金额。本发明通过构建双层计算模型,利用灵敏度算法计算路段的实际投资成本和最大关键度的最小值,既确定了应急疏散路径中最为重要的路段,也得出了该路段的实际投资金额,从而以最小的投资成本提高路段的可靠性,使路网系统最薄弱的环节得到加强,对客滚船旅客的应急疏散路径网络系统进行有效地优化。
