基于Vague集理论的大运量快速交通方式评价与选择

The Mass Rapid Transportation Evaluation and Selection based on the Vague Set Theory

大运量快速交通系统是一种介于地面常规公交与轨道交通之间的交通方式,建设大运量快速交通系统对于合理利用城市经济资源和优化城市土地利用布局等方面具有深远意义。在具体的交通方式选择决策中,采用以Vague集理论为基础的模糊物元分析方法,并以信息论中熵权计算方式确定不同指标权重,考察各方案与理想方案及负理想方案之间的距离,以此来表示各方案的相对效率指数。

Mass rapid transportation system is a middle mode between conventional bus and rail transit。 The construction of mass rapid transportation system is good for urban economic resource utilization and land use. During the specific transportation mode selection, we use fuzzy matter element analysis method based on the theory of vague sets,then determine different index weights by entropy calculation. Finally, the distances to ideal solution and to negative solution are examined, in order to indicate the relative efficiency of the programs.
