Unit 12 coordination of container transport

There is a fixed number of container terminals, called sites. Each pair of sites is connected by exactly two routes: one in each direction. A fleet of vehicles is available to carry out the transport. All vehicles are operationally equivalent and all carry single loads; on average a loading or unloading handling will take one to two minutes, exclusive waiting times. The fleet is managed by a fleet manager. Each site is managed autonomously by a site manager. On the request of the site managers, the fleet manager allocates vehicles to be hired by the site managers. Next, within these allocations, each site manager issues transportation jobs and assigns these jobs to the allocated vehicles.

However, because of the autonomy of the terminal operators, such a setup is organizationally not acceptable. More precisely, the objectives of the fleet manager on one side and the objectives of the site manager will differ and, dependent of the operational situation, may be conflicting. The objective of the fleet manager is to avoid unpaid empty driving and to keep the size of its fleet just large enough the serve the demand for vehicles. The objective of the site managers is to minimize the operational costs. Then the challenge is to develop a real-time optimizing coordination system for the deployment of vehicles and the execution of transportation jobs that respects the autonomy of all participants.
