非随机干扰导致了时刻表驱动的客运铁路交通延误管理的必要性。最大限度地减少延误的负面影响成为经济成功的最相关的挑战之一，因为它直接影响到乘客的及时性，这是客户满意度的核心指标。在这篇文章中，我们评估和比较各种延误管理策略在客运铁路网络。已经实现了一个模拟器，以产生延误，并执行操作控制决策，以解决连接冲突引起的乘客连接涉及延误的列车。我们比较了基于数学优化的调度策略与简单的基于规则的策略。对德国铁路长途客运时间表的模拟表明，由于该决策问题的在线性质，简单的等待时间规则策略优于每次中断后在线重新优化运营的策略。© 2010 Wiley Periodicals，Inc.网络，2011年
Unavoidable disruptions induce the necessity of delay management in timetable‐driven passenger rail traffic. Minimizing the negative consequences of delays becomes one of the most relevant challenges for the economic success, as it directly affects the timeliness of passengers, which is a core indicator of customer satisfaction. In this article, we evaluate and compare various delay management strategies in a passenger railway network. A simulator has been implemented to generate delays and perform operations control decisions to resolve connection conflicts induced through passenger connections involving delayed trains. We compare dispatching strategies based on mathematical optimization with simple rule‐based strategies. Simulation runs with a timetable from the long‐distance passenger traffic of German Railways show that, due to the online nature of this decision problem, a simple waiting time rule strategy can outperform a strategy where the operations are reoptimized online after each disruption. © 2010 Wiley Periodicals, Inc.
