摘要: 针对现有对点对点应急疏运组织研究存在的不足,以多目标优化为研究方法,分析了不同应急疏运目标对整体应急疏运效率的影响,讨论了多目标 应急疏运的必要性,并重点考虑最小距离和最小风险两个应急疏运组织目标。针对点对点应急疏运的网络特性与约束条件,构建了点对点多目标应急疏运 组织优化模型,并采用NSGA-II算法实现了多目标优化模型的求解。通过对应急疏运网络上增加各路段的风险值,设计并求解算例,体现出更客观有效的 应急疏运策略。

Abstract: According to the problems of the point-to-point emergency evacuation organization in current research, the influence of different emergency evacuation objectives on the total emergency evacuation efficiency was analyzed in the view of multi-goal optimization. Two targets of emergency evacuation organization were focused, that is the minimum distance and minimum risk.The multi- goal optimization model for the point-to-point emergency evacuation organization was established in accordance with its network features and constraint conditions.Meanwhile, the NSGA-II algorithm was proposed to solve the multi-goal optimization model.By increasing the risk values of each section of the emergency evacuation network, the case studies were designed and solved, which reflected a more objective and effective emergency evacuation strategy.

Key words: traffic engineering, point-to-point emergency evacuation, NSGA-II algorithm, emergency evacuation, minimum risk;multi-goal optimization
