摘要
客运专线时期列车运行调整对象更加多样化和复杂化。结合目前我国客运专线运输组织情况,建立了客运专线列车运行调整的运筹学模型。提出了基于混沌改进的遗传算法,引进了混沌算子,以郑西客专为研究背景构造实例。仿真结果验证了优化模型的可行性,表明改进算法优于标准遗传算法。
The subjects of Passenger-Dedicated Lines(PDL) train operation adjustment become more complicated.The PDL transport organization of China is analyzed,constructed a operations research model,proposed adjustment model based on chaos-improved GA,and design chaotic mutation operator.Lastly,an experimental example about Zhengxi PDL is constructed.The simulation results demonstrate the feasibility of the optimization model,and the improved algorithm is better than the standard one.
