【摘要】：高速公路应急救援资源多分散于其网络中的各个管理所,应急救援时快速和有效地调度这些分散的资源,对于降低交通事故损失至关重要。通过分析高速公路应急救援工作的基本流程、管理方法及存在的问题,基于系统资源共享、区域联动的动态调度模式,以应急救援资源到达应急救援需求点的总成本最低为优化目标,以高速公路管理所静态管理资源和在途动态管理资源以及救援时效等为约束条件,构建高速公路应急救援资源动态调度优化模型。运用Dijkstra算法对其进行求解。以某高速公路网为算例,运用该模型并进行算法设计,以实现模型的优化求解。结果表明,用该方法能从众多备选出救点集合中快速搜索出应急救援所需要的最佳出救点和出救路径。
[Abstract]:Expressway emergency rescue resources are mostly scattered in each management station in its network. It is very important to dispatch these scattered resources quickly and effectively in emergency rescue for reducing the loss of traffic accident. By analyzing the basic flow, management method and existing problems of expressway emergency rescue work, the dynamic dispatching mode based on system resource sharing and regional linkage is analyzed. Taking the minimum total cost of emergency rescue resources to reach the point of emergency rescue needs as the optimization objective, taking the static management of resources and the dynamic management of resources on the way, as well as the time limit of rescue as the constraint conditions, the highway management institute can manage the resources statically. The dynamic scheduling optimization model of expressway emergency rescue resources is constructed. Dijkstra algorithm is used to solve the problem. Taking a highway network as an example, the model is used and the algorithm is designed to optimize the solution of the model. The results show that this method can quickly search out the best rescue point and rescue path from many sets of alternative rescue points.
