基于熵权灰色关联分析法的市域铁路线路方案比选研究

Study on Route Scheme of Regional Railway Based on Entropy Weight and Grey Relational Analysis Method

根据我国市域铁路的特点及其现状,分析市域铁路线路方案比选的各种影响因素。通过从市域铁路线路总长度、吸引客流量、环境保护以及既有铁路资源利用率等多方面切入,建立关于市域铁路线路比选评价指标体系。运用熵权法和灰色关联分析法对市域铁路线路方案进行比选,从备选方案中选择最优方案,并结合实例进行分析。

According to the characteristics of regional railway in China, the internal and external factors of regional railway route scheme are analyzed. Based on the total length, passenger volume, environmental protection, utilization of existing railway resources and so on, this article establishes the evaluation system of regional railway route scheme. Adopting entropy weight and grey relational analysis method, the best scheme could be chosen. At last, a practical example is demonstrated.
