公路网灾害应急救援点多目标选址模型及算法

为减少自然灾害频发对公路交通带来的损失，研究并建立针对自然灾害的区域公路网应急救援点显得十分必要。本文首先从公路自然灾害应急救援点的功能需求、选址影响因素、选址要素（顾客、设施、空间、度量）和选址目标等方面对救援点选址规划特征进行了研究。然后从公路应急救援的快速反应、集合覆盖、灾害损失最小化等三个方面提出了公路网应急救援点的多目标选址优化模型，并探讨了模型的求解算法和求解步骤，通过lingo软件编程实现优化目标的求解。最后通过浙江桐庐公路网的应急救援点规划这一实例对提出的选址优化模型进行了应用。

Multi objectives Location Planning Model and Solution Algorithm for Disasters Rescue Site of Highway Network

In order to reduce the losses resulting from frequent natural disasters in highway transportation, it is essential to study on and set up natural disasters rescue sites in regional highway network. Firstly, the characters of highway emergency rescue site location planning were analyzed from four aspects including the functional requirement, location impact factors, location elements (customers, facilities, space and measurement) and location objectives of emergency rescue site. Base on three objectives in rapid response, set covering and disaster loss minimum, a multi-objectives decision model for location optimization was established. Then the algorithm and procedures of this model were discussed and the optimized objective was achieved through the Lingo programming. Finally, the method of rescue site planning has been applied to the Tonglu highway network in Zhejiang province.
