| 摘 要： | 基于我国城市家庭小汽车普及率低的现状，构建停车场、车站以及避难所三者组成的疏散网络。以车辆总疏散行程时间最小为目标，建立以公共交通工具（客车）作为主要工具的紧急疏散路径优化模型，并设计基于最小费用、最大流的求解算法。通过算例说明模型和算法的有效性和可行性，并得到在给定的疏散路网方案情况下，停车场现存车数、车站所需车辆数以及避难所容车数的变化，会引起所有客车最短径路选择变化的结论。

| Abstract: | For the situation of low car ownership rates in Chinese cities,an evacuation network combining with the parking lots,stations and shelters is formulated.Aiming at minimizing the total evacuation travel time,a path choice optimization model of the public transportation vehicles(here the buses) for evacuation is established,as well as its solution algorithm via the Max-flow/Min-cost model.The feasibilities and the effectiveness of both the optimization model and its solution algorithm are evaluated by a case ... |
