| 摘 要： | 从高速公路网与物流网络同构相似的关系出发，将高速公路网纳入物流网络体系并构建高速公路物流网络．结合选址-路径问题（LRP）模型来探讨高速公路物流网络规划的方法，把高速公路物流网络规划分解为高速公路服务区作为物流节点的选址布局问题和高速公路作为物流通道的路径安排问题；使用遗传算法对该模型进行求解，并对遗传算法的要素进行设计和改进，提高了求解的精度和效率；最后，通过算例分析验证了模型的实用性和算法的有效性．

| Abstract: | According to the similarity between expressway network and logistics network,Expressway network is incorporated into logistics network,and logistics network of expressway is constructed.Through studying logistics network planning of expressway on the basis of Location-Routing Problem model,the problem of logistics network planning of expressway can be divided into the location of service area of expressway which is regarded as the logistics node,and the routing of expressway which is considered as logistic passage.In this paper,Genetic Algorithm for this model is proposed,and GA is improved for efficiency and precision.Finally,both practicability of the model and the efficiency of the algorithm are illustrated by a calculation example. |
