The Great Lakes Shipping company ships pallets of goods from an origin to a destination. Sometimes the pallets get loaded onto boats and shipped across a lake, but many pallets get loaded onto trucks for some portion of their trip. The company is making use of cutting$-$edge tech and has invested in self$-$driving electric vans for last mile delivery. They need to be able to track pallets, assign them to a boat or truck or van, load, and unload pallets. Each boat has a captain, and each truck has a driver. In addition, with fuel prices fluctuating, they need to track fuel on the boats and trucks. All vehicles that use fuel, use diesel.
