摘要: 列车开行方案是编制列车运行图的基础,合理设计列车停站方案对区段内的客流分配有着直接影响。通过研究现行的列车开行方案,结合客流量等数据,考虑提高线路通过能力和列车能力利用效率,进行本线列车与跨线列车的协同优化研究。结合数据,提出假设条件,建立本线与跨线高速列车开行方案协同优化模型。使用多目标优化的线性加权算法进行目标函数的转化和求解,并以京沪高铁为案例,对模型的参数进行标定,得到本线与跨线列车协同优化开行方案。通过对现行方案与优化方案的车站服务频率、停站次数等的对比分析,验证了模型的有效性和可行性。Abstract: Train operation scheme is the basis for the preparation of the train operation diagram. The reasonable design of train stop station plan has a direct impact on the distribution of passenger flow in the section. Through the study of the current train operation scheme, combining with the passenger flow and other data, considering the improvement of the line capacity and the utilization efficiency of the train capacity, this paper carried out the collaborative optimization research of this line train and cross line train. Based on the data, the paper puts forward the hypothesis conditions and establishes the collaborative optimization model of this line and cross line high-speed train operation scheme, used linear weighting algorithm of multi-objective optimization to transform and solve the objective function. Taking Beijing Shanghai High-speed Railway as an example, the paper calibrated the parameters of the model, and obtained the coordinated optimization scheme of this line and cross line train operation.The validity and feasibility of the model are verified through the comparative analysis of the station service frequency and stop station times between the current scheme and the optimized scheme.
