Liner carriers move vessels between routes in their networks several times a year in a process called fleet repositioning. There are currently no decision support systems to allow repositioning coordinators to take advantage of recent algorithmic advances in creating repositioning plans. Furthermore, no study has addressed how to visualize repositioning plans and liner shipping services in an accessible manner. Displaying information such as cargo flows and interactions between vessels is a complex task due to the overlap of container demands and long time scales. To this end, we propose a web-based decision support system designed specifically for liner shipping fleet repositioning that integrates an extended version of a state-of-the-art simulated annealing solution approach. Our system supports users in evaluating different strategic settings and scenarios, allowing liner carriers to save money through better fleet utilization and cargo throughput, as well as reduce their environmental impact by using less fuel.

班轮运输船队重新定位的决策支持和数据可视化

班轮承运人每年将舰队在其网络中的路线之间转移几次，这称为车队重新定位。当前没有决策支持系统允许重新定位协调员利用最近算法的进步来创建重新定位计划。此外，还没有研究涉及如何以可访问的方式可视化重新安置计划和班轮运输服务。由于集装箱需求的重叠和较长的时间尺度，显示诸如货物流和船只之间的相互作用之类的信息是一项复杂的任务。为此，我们提出了一个基于网络的决策支持系统，该系统专为班轮运输船队重新定位而设计，它集成了最新模拟退火解决方案方法的扩展版本。
