Fun fact: ship scheduling in Rotterdam is a similar exercise in politics. I think the NextLogic centralized barge scheduling initiative started back in 2012 or so (https://www.nextlogic.nl/en/) and is only running in production for a handful of terminals and barge operators since the start of this year. Centralized planning is a bitch of a problem, not for technical reasons, but for political ones. I could go on and on about the various reasons parties did not want to participate, even though in principle everybody agrees that a centralized planning will be more efficient than every terminal doing it on their own.
