基于节点重要度的公路运输站场建设序列

Optimizing Items Order of Highway Transport Terminals Based on Analyzing Importance of Nodes

针对传统方法确定公路运输站场建设序列的不足,提出基于节点重要度分析的公路运输站场建设序列确定新方法。利用层次分析法确定权重来计算运输节点的重要度指数,根据运输节点处公路运输站场需求将节点重要度指数修正为节点处公路运输站场需求指数,通过对公路运输站场需求指数,采用循环比较法得出公路运输站场的建设序列。运用该方法对广西玉林市所辖6个区县的11个公路客运站建设项目进行新的排序,所得建设序列更符合各运输节点对公路运输站场的需求。结果表明,基于节点重要度的公路运输站场建设序列优化方法优于经验判断法,是一种新的公路运输站场建设序列确定方法。

To remedy deficiency of empirical method to planning construction order of highway transport terminals, this paper presented a new method of layout construction order of terminals embedding node importance analysis. The importance indices of each node were calculated with AHP, those indices were revised to highway transport terminal＇s demand indices. The construction order was designaed based on comparing terminal＇s construction indices recurrently. With practical example in Yulin city of Guangxi province, 11 intercity bus terminals in 6 nodes were redesignned by the new method. The results show that the new method is more reasonable than original scheme. All the works indicate that the method embedding node importance analysis is excelled empirical method and is a new idea to design construction order of highway transport terminals. 3 tabs, 9 refs.
