基于J2EE的铁路编组站车流仿真系统设计

Design of Wagon-Flow Simulation System of Railway Marshalling Yard Based on J2EE

由于铁路编组站车站调度员很难掌握自动编制阶段计划推流、配流的全过程,导致自动编制的阶段计划在车站无法被工作人员接受,最终导致计划无法很好地实施,针对这种情况,分析了问题存在的原因,并提出了建立一个可以仿真车流随计划动态变化、统计计划预执行情况、根据统计结果为站调提供决策支持的车流仿真系统。阐述了基于J2EE的铁路编组站车流仿真系统的设计思路,给出了针对此系统的J2EE软件集成方案和部分核心技术(Remote Service和Fa ade等)的具体实现。也给出了车流随阶段计划动态变化、对车流仿真结果进行统计、为站调提供调整计划策略的实现方法,最后给出了仿真结果。

Phase plans which are scheduled automatically can＇t be accepted by the staff in the marshalling yard, because the station dispatcher does not well know how the wagon-flow of the automatic phase plan was calculated or distributed. In such cases, the reasons of the problem were analyzed, and a system called wagon-flow simulation system was established to simulate the dynamic change of wagon-flow according to the phase plans. Also it could count and analyze the result of the implementation of the plans, then provide decision support for the station dispatcher according to the statistics. The design ideas of the system based on J2EE were proposed, and the ways of programming of partial key technologies such as Remote Service and Facade were given. At the same time, the implementation method of dynamic changed of the wagon- flow according to the phase plan, counting the results of traffic simulation and providing the strategy of adjustment for the station dispatcher were described. Finally, the simulation results were showed.
