高速磁浮车站客运列车作业方案优化研究

A Study on Optimization of Passenger Train Operation Scheme in Highspeed Maglev Station

为提高高速磁浮旅客运输作业效率,以列车时刻表为基础,优先考虑列车按图行车条件,综合考虑列车在车站运行的总耗时,以列车径路占用唯一性、径路交叉疏解等为约束条件,构建高速磁浮车站列车作业径路优化模型,设计基于高速磁浮车站列车作业逻辑的适应度函数,构建求解模型的模拟退火算法,并通过高速磁浮通过式始发站进行算例检验。结果表明,优化方法能够在列车“按图行车”条件下有效提高列车的径路方案质量和在站作业效率。

In order to improve the operation efficiency of high-speed maglev passenger transport,this paper built an optimization model of the train operation route of a high-speed maglev station based on the train timetable and gave priority to the train operation as per the diagram,comprehensively considered the total time consumed by the train in stations,and took the uniqueness of train route occupation and route crossing relief as constraint conditions,and designed an adaptability function based on the train operation logic of high-speed maglev station.A simulated annealing algorithm for solving the model was constructed,and an example test was carried out with the high-speed maglev through-type departure station.The results show that the optimized method can effectively improve the quality of train route scheme and the efficiency of onstation operation under the condition of“train operation as per the diagram”.
