高速铁路网络能力计算研究

充分考虑高速铁路网络作为多级递阶控制系统的复杂性和对旅客运输服务质量的要求,构建基于时段特定场景的高速铁路列车服务与需求意向集合（t@n-tsdis,train service-demand intention setat network）,定义以完成这个集合所需基础设施占用时间为网络能力的衡量标准。提出了两阶段的优化计算方法,并提出多目标优化改进的Pareto（1+1）— PAES算法流程,采用交互式滚动优化策略处理整数约束条件、模糊逻辑罚函数法处理连续实数约束条件、Pareto存档进化策略求解多目标优化问题。以某高速铁路网络为例进行能力计算,验证了模型与算法的有效性。

Calculation of network capacity for high-speed railway

Taking full account of the high speed railway network as the complexity of the multilevel hierarchical control system and requirements for the quality of passenger transport service, this article set up the high-speed train service-demand intention set at railway network according to the specific scenario of the period ( train service-demand intention set at network, abbreviated as t@n-tsdis ), and then took the occupation time of the infrastructures needed to fulfill the set as the criteria to measure the network capacity, proposed the two stage optimization calculation method. On solving the model, the article proposed improved (1+1)-PAES Algorithm flow for multi-objective optimization, and took the interactive-rolling strategy to tackle the integer constraints, the fuzzy-logic penalty function to tackle the real constraints, and the Pareto archived evolution strategy to solving multi-objective optimization problems. The model and the Algorithm were applied to a high speed railway network for case study, the validity of the model and the Algorithm was verified.
