Evaluation Theory and Method of High-Speed Train Diagrams

In order to improve the quality of high-speed train diagram,a complete evaluation index system for high-speed train diagrams was established. In the system,the evaluation indexes are extracted from three aspects,i. e.,the train diagram production efficiency,passenger service quality, and dynamic performance; and their quantification methods are provided. As an example,the train diagram of the north section of Zhengzhou-Xi'an high-speed railway was evaluated using the proposed method. The result shows that the proposed evaluation index system is convenient and feasible for a single train diagram evaluation,and it is also can be used for comparison of multiple train diagrams. The grey evaluation result of Zhengzhou-Xi'an north section is 3. 294,indicating the good quality of the train diagram.
