摘要
客专时期列车运行调整的对象更加多样化和复杂化,采用高效率的运行调整避免晚点传播现象,成为运输组织的焦点问题。针对此问题,对客专列车运营模式进行分析,建立了客运专线列车运行调整的数学模型,提出了基于混沌改进的遗传算法列车运行调整模型,设计了混沌变异算子,以郑西客运专线构造实例,仿真结果验证了优化模型可行性,表明改进算法具有优越于标准GA的优化能力。
The objects and subjects of Passenger-Dedicated Lines （PDL） train operation adjustment become more complicated at the period of Passenger-Dedicated Lines（PDL）,researching high efficient operation adjustment measure to avoid delay propagation is becoming a focus of PDL transportation organization.Aiming at this problem,this paper analyzes PDL train operation adjustment model,constructs the mathematical model of PDL train operation adjustment,proposes train operation adjustment model based on chaos-improved GA,and designs chaotic mutation operator.At last,an experimental example about Zheng-Xi PDL is constructed, the experimental result demonstrates that the improved algorithm can acquire a better optimal ability than SGA,and the improved adjustment model is feasible.
