The unloading process at container terminals can be described
as follows. Vessels arriving at container terminals are assigned to
a berth. Upon mooring, vessels are unloaded by one or more quay
cranes according to an unloading plan. Containers are then relayed
to transfer vehicles, which transport them to the storage yard
where they are temporarily stored (typically) by yard cranes.
Depending on their destination, containers might be transshipped
to another vessel, or dispatched via the terminal gates for transport
by trucks or trains after being inspected. The loading process at
container terminals is the reverse of the unloading process, except
that the loading is done according to a loading (or stowage) plan.
Typically, the loading of the vessel occurs after the unloading process
is completed. The logistical challenge for container terminals
arises as at any point in time there might be several moored vessels,
some of which are being unloaded and others loaded. Terminal
managers aim in operational decision making to minimize
vessels’ turnaround times while meeting agreements with shipping
companies. For a more detailed description of all the decisions
made in container terminals the readers are referred to Vis and De
Koster (2003) and Steenken, Voß, and Stahlbock (2004).
