Challenge: can you find the best plan to refuel locomotives?

Via the INFORMS newsletter, I found out this cool competition (trains and analytics, how much cooler can it get?): can you find the best plan to refuel the locomotives of a railroad company?

Create a cost-effective plan to fuel the locomotives that power a railroad’s trains. Specify how many fuel trucks to contract at each yard and how much fuel to dispense into the locomotives of trains that run over a specified time horizon. Ensure that no locomotive runs out of fuel en route between yards. Sounds easy? We’ll see about that!
