基于信息颗粒的城市轨道交通换乘枢纽评价研究

随着城市轨道交通网络的不断扩大,换乘枢纽的地位越来越突出,成为影响轨道交通效率和服务水平的主要因素.分析了换乘枢纽的评价指标体系.由于指标信息数据的不完备性,利用模糊聚类对不完备信息表进行完备化,并引入经典粗糙集理论阐释了信息颗粒的含义,构造了信息颗粒;提出了基于粗糙信息颗粒的属性约简算法,建立了轨道交通换乘枢纽评价模型.通过示例说明了该方法的有效性,并给出了基于给定阈值的置信度评价规则集.

Evaluation of Urban Mass Transit Transfer Hub based on Information Granules

With the expansion of mass transit network,the position of transfer hub becomes more and more important.In this paper,the evaluation index system is discussed,the fuzzy-cluster is used because of the incomplete data.Since the rough set is introduced to construct information granules,this paper explains its meanings,gains a complete information table,then puts forward an algorithm for the attribute reduction to establish an evaluation model.Finally this paper uses an example to testify its efficiency,and pro...
