标题： Real-time Optimization of Transport Chains for Single Wagon Load Railway Transport

摘要： 瑞士国家铁路公司的货运部门SBB Cargo，为其客户提供在货车运输系统（WLV）中运输单个或少量货车的服务。 在此系统中，货车沿着一条运输链行驶，运输链是由连续的列车组成的序列。 最近，SBB Cargo重新设计了其IT系统，并更新了这些运输链的计算方式。 本文描述了主要的设计决策和技术细节：数据结构、搜索算法、实时环境下的吞吐量数学优化，以及一些使算法在操作软件中运行的选定细节。 我们还对所采用的技术栈进行了评论，并最终展示了运行操作中的一些性能指标。 显示英文摘要

摘要： The freight branch of the Swiss national railways, SBB Cargo, offers customers to ship single or few wagons within its wagon load transportation system (WLV). In this system, wagons travel along a transport chain which is a sequence of consecutive trains. Recently, SBB Cargo redesigned its IT systems and renewed the computation of these transport chains. This paper describes the main design decisions and technical details: data structures, search algorithms, mathematical optimization of throughput in the real-time setting, and some selected details for making the algorithms work in the operational software. We also comment on the employed technology stack and finally demonstrate some performance metrics from running operations.
