面向地震应急的救援路径规划模型

地震灾害场景下，面向应急的救援路径规划需要兼顾救援效率和交通抢通对救援的影响，以支撑有限交通资源的高效利用，避免交通拥堵或瘫痪耽误应急救援行动.通过定义面向应急需求的交通网络、交通路线的通行成本和交通线的通过性等，对救援与抢通路径规划问题进行了描述；将最优救援路径和最优交通抢通方案作为该问题的约束条件，基于双层优化方法建立了双层路径规划模型以实现集成优化并构建了模型求解方法.经案例仿真分析，本文提出的救援路径规划模型可以生成准确、高效的应急救援与交通抢通集成方案，可以为具有针对性的交通管制措施的拟定提供科学依据，助力地震应急救援行动的顺利实施.

Rescue Path Planning Model for Earthquake Emergency

In the earthquake disaster scenario, the rescue path planning for earthquake emergency should aim at rescue efficiency taking into account the impact of emergency traffic restoration on it, to support for efficient use of the limited traffic resources, avoiding traffic congestion or paralysis that could delay emergency rescue operations. By defining the traffic network, traffic cost, traffic passability and so on for emergency, the problem of rescue and traffic restoration path planning is described; taking optimal rescue path and optimal traffic restoration scheme as the constraints of the problem, a model of bi-level path planning based on the bi-level optimization is eatablished for the purpose of integrated optimization and the solution method of the model is proposed. It is validated that an accurate and efficient integrated emergency rescue and traffic restoration plan is able to be prepared by the proposed model, which can provide scientific decision basis for targeted traffic control measures, and help improve the efficiency of earthquake emergency rescue.
