| 摘 要： | 为了研究道路客运站场规划的站场选址优化，提出了一种基于多目标优化的道路客运站场选址方法。首先，将道路客运站场规划区域的道路网简化为有向赋权图，使选址优化问题转化为0-1规划问题；然后，以道路客运站场的建设投资、网络总运输成本以及乘客的总出行距离为优化目标，同时把道路客运的实际条件转化为优化目标的约束条件；最后，利用基于目标值排序组合选择的多目标遗传算法求解模型的Pareto最优解集合，并通过客运站场选址优化算例阐述了模型的求解过程。

| Abstract: | To determine the location of hubs in road passenger transportation plan, a method based on multi-objective optimization is presented in this paper. First, the road passenger transportation network in planning area is simplified as a directed graph and the hub location problem is transformed into 0-1 planning problem. Then the total hubs building cost, passenger network transportation expenses, and trip distance is selected as the optimization objectives, which is subject to the actual conditions of road passenger transportation. Finally, multi-objective genetic algorithm based on the selection after multi-objective value ordering and combining is adopted for model solution, and a computation example of passenger hub location is tested and analyzed. |
