If you find container shipping interesting, and perhaps Maersk specifically, Markus Völter did an episode [1] on the topic on his Omega Tau podcast a while back. The episode also goes into some depth about how optimisation is applied to some of the processes in the industry. Full disclosure: I am one of the interviewees.
