铁路客运车站股道运用优化模型及算法研究

A Study of the Optimization Model and Algorithm for Track Application in Railway Passenger Stations

为了提高铁路客运车站的生产作业效率和自动化水平,本文通过对客运车站作业特点及股道运用计划的调查分析,以有效利用车站设备、提高车站接发车对数为目的,考虑车站接发车作业过程中的交叉干扰以及进路建立过程中的技术作业时间差,分别以股道占用时间和空费时间的方差来衡量股道运用的均衡性,建立了股道运用均衡的多目标模型,并用布谷鸟算法求解模型,以实际车站数据进行验证,结果证明了模型的可行性及优越性.

In order to improve railway passenger stations＇ production efficiency and automation level, this paper, through an investigative analysis of passenger stations＇ operation characteristics and track use plans, with the efficient use of railway stations＇ equipment and increasing train departures and arrivals as the object, and taking into consideration the cross interference by arrivals and departures and the technical operation time difference in the approach process, measures the equilibrium of track use using the variance of the hold-up time and time unoccupied respectively, establishes a balanced multi-purpose model for track use, adopts a cuckoo algorithm, and validates the model against actual station data. The results prove the feasibility and superiority of the model.
