摘要：

列车运行线作为构成列车运行图的基本单元，其效率反映列车运行图编制质量.定义列车运行线效率为其反馈技术指标与占用运输资源的赋权比，给出各影响因素的计算方法；针对其相对性特点，基于DEA-CCR模型构建全图列车运行线效率计算模型并求解.以成遂线石板滩—新桥线路所列车运行图进行实例验证，结果表明，所提方法能够客观计算列车运行线效率，算例中动车组列车运行线效率均值为0.961 1，高于普速列车均值0.909 5；全图上行方向列车运行线效率均值为0.944 2，高于下行方向均值0.933 7，说明列车运行线效率与铺画优先级及始发时刻可调整度有关，并提出了改善列车运行线效率的途径.

Abstract:

As the basic unit of train diagram, the train path efficiency is the key to evaluate the train diagram drawing quality. Define the train path efficiency as the weighted ratio of feedback technical indexes and transport resource indexes, and give the calculation method of train path efficiency elements, considering the relative feature, based on DEA-CCR model built a train path efficiency calculation model and solved. Chengsui railway Shibantan to Xinqiao sector block train diagram is used as a study case. The results show that the proposed method can get an objective value of train path efficiency, in the case, the EMU train paths have an average efficiency value of 0.961 1, higher than normal train with 0.909 5; the overall up direction train paths have an average efficiency value of 0.944 2, higher than down direction trains with 0.933 7, these indicate that the train path efficiency is affected by the drawing priority of train paths and adjustable degree from the departure station, the ways to improve the train path efficiency are given.
