摘要
利用信息熵分析和优化了城市轨道交通运营安全评价指标体系,建立了基于数据包络分析(DEA)的城市轨道交通运营安全评价的C2R模型.以广州地铁一号线为例,应用该模型对历年运营的安全性进行了评价与分析,并运用Matlab软件编程进行了求解.根据计算结果,在产出指标确定的情况下,对非DEA有效的决策单元的输入指标进行了有效的调整.
The index structure system of urban rail transit is analyzed and optimized by applying information entropy,and a safety evaluating C2R model on analyzing urban rail transit is set up based on DEA.Finally,a case study of Guangzhou Metro Line 1 is carried out,and annual relative validity of subway operation safety is evaluated by using the Matlab software program.According to the results of the calculation,and in invariable circumstances of output indexes,the input indexes of non-DEA effective decision making units are adjusted.At last,the conclusion according to the front real analysis and suggestions as well as the countermeasures are elicited.
