动车组列车车底交路优化研究

高速铁路、城际铁路以及客运专线正在随着我国高速铁路技术的发展，日益呈现着不断扩建的趋势。作为上述运输生产技术中最为核心的部分，动车组列车的生产和检修成本比重较大。因此，降低动车组列车数目、提高列车的运行效率，对于提高高速铁路经济性来说意义重大。在分析动车组运用计划概念、动车组交路计划约束因素的基础上，以动车组交路为优化目标，构建了动车组交路优化模型及算法，并进行了实例验算，验证了方法的有效性。

Optimization of EMU Train Stock Routing

With the development of technology for China high-speed railway, high-speed railway, inter-city railway and passenger dedicated line are built and expanded. As the most important mobile devices in transportation and production tasks, the production and maintenance cost of EMU takes a large part in whole investment. So, reducing the number of EMU and improving the operating efficiency of the train has important meaning for improving the economy of high-speed railway. On the basis of analyzing the con-cept of train-set scheduling and restriction factors of EMU routing scheme, taking EMU routing as optimi-zation object, the article establishes the optimization model and algorithm, and sets example to verify the validity of the method.
