铁路客运站的瓶颈区段非常复杂，需要长时间进行频繁的技术和调车作业。站线与机务段、客车整备场的衔接对客运站的通过能力也有很大的影响。因此，在工程项目和实践中，存在着许多优化问题。提出了一种基于均衡性和最小化总占用时间的瓶颈优化模型，通过合理安排进路和道岔组来提高通过能力。利用模拟退火算法对该规划进行求解，并给出了优化策略。以我国客运站瓶颈路段优化为例，说明了该模型的应用。
The bottleneck section of a railway passenger station is very complex, and many frequent technical and shunting operations are performed over a long time. The connection of station tracks, locomotive depots, and passenger train stock servicing yards also have great effects on the carrying capacity of a railway passenger station. Therefore, there have been many optimization problems in engineering projects and practices. This paper proposes a bottleneck optimization model to enhance the carrying capacity by reasonably arranging routes and groups of turnouts with the consideration of proportionality and minimized total occupation time. The simulated annealing algorithm is provided to solve this programming, and the optimized strategy is given. A case study focused on the bottleneck section optimization in the passenger station of China illustrates the application of the proposed model.
