高速公路养护站点选址模型及其应用研究

Model of Location for Highway Maintenance Site and Its Application

针对高速公路养护站点设置时的经济性和时效性要求,综合考虑养护站点固定费用和养护材料运输费用,构建了使总费用最低的高速公路养护站点多目标选址数学模型;给出了算法求解步骤;通过实例得出最佳的养护站点设置数量及最佳位置。结果表明:该模型和算法是合理的,对于高速公路养护站点选址具有一定的参考价值。

According to the requirements of economy and timeliness for setting the highway maintenance site,the multi-objective model of location for highway maintenance site was established with the lowest total costs,which considered the constant costs and transport costs of maintenance site. And then,the corresponding algorithm was also given. Finally,the best quantity and location of maintenance site was obtained through the case study of highway network. The results show that the proposed model and algorithm are both reasonable,which has certain referential value for the selection of location of highway maintenance site.
