大秦线港口站对位卸车模型及算法

Research on para-position unloading model and algorithm in port station of Datong-Qinhuangdao Railway

本文结合大秦线港口站卸车方式,综合考虑车流的集中到达、列车的限制性对位因素,建立了以待车时间最短,且翻卸时间最短的数学模型,用模拟退火算法进行求解。通过算例对模型和算法进行了验证,生成最优翻车机对位计划,为港口站加快卸车效率、车站智能化提供了较好的解决途径。

This paper established a model of the shortest waiting time and the shortest unloading time based on the characteristics of the unloading method in the port station of Datong-Qinhuangdao Railway, considering the concentrated traffic flow and the restrictive para-position factor of the train. This model used Simulated Annealing Algorithm approach. The optimization effect was obvious by verifying the model and algorithm with an example. This paper provided the better way to improve the unloading efficiency and the intelligentilize in the railway station.
