基于离散事件系统的客运专线车站作业仿真系统研究

客运专线动车组运行具有小编组、高速度和高密度的特点,客运专线车站作业组织中对时间要求严格,作业复杂性增加,使得在实际运营过程中很难用公式对其车站各种能力和指标进行准确描述,而系统仿真则是解决这一问题的有效方法.进行客运专线车站作业系统仿真的研究可以为客运专线车站设计提供支撑和建议,为运营提供可靠的参考数据.车站作业系统是一个典型的微观离散事件系统,旨在此系统理论基础上研究客运专线车站作业仿真的方法,构架仿真系统结构,建立车站作业仿真模型,设计咽喉区进路排列优化高速算法与到发线运用问题的解决方案等,在此基础上开发客运专线车站作业仿真系统,证明论文所研究车站作业仿真模型、子模型及选择的仿真策略的有效性.

Study on Station operation SimulatiOn System of PaSsenger Dedicated Line based on Discrete EVent System

Electric multiple unit operation on the Passenger Dedicated Line had the features of less marshalling, high speed, and high frequency, trains in an initial station had a larger quantity than that in an existing railway station with similar situation, that meant a complex situation in station operation but little study on it. Study on the Passenger Dedicated Line Station Operation Sim-system could provide the theoretical support and suggestion in yard designing and reference database for further operation. Station Operation Sim-system was a Typical Discrete Event System from microcosmic view, it was required to track state parameters of technological processes of any train to obtain detailed information. Based on the mentioned theory, it was established a system simulation model of station operation, designed a high speed optimized algorithm of throat route arranging and optimized scheme of application of arrival-departure lines, then developed the Station Operation Sim-system, presented an example to calculate an example station capacity with System. The effectiveness was proved.
