De planning van kranen op een containerterminal.
Literature survey,
Report 2001.LT.5471, Transport Technology, Logistic Engineering.
Ninety percent of the international transport nowadays visits mainports.
The general cargo shipped is for over eighty percent containerized.
Because a containership is highly capitalized and their operation costs
are very high, it is very important that the turn-around time of a
container ship in a port container terminal is as short as possible. That
is why the loading and unloading operations have to be planned very well.
The subject of this paper is a survey of research on scheduling of terminal
operations where cranes are involved. The overall
goal is to minimize the time spent in port by the container ship. The
scheduling of terminal operations is divided into two subproblems.
The first subproblem is the scheduling of the quay crane. The methods for the
scheduling of the loading and unloading operations are described. The
scheduling problem is divided in static and dynamic scheduling problem. In
the static version all the ships are at the starting point located in the
port, where in the dynamic problem ships can still arrive while the
loading or unloading is started.
The second subproblem is the scheduling
of the cranes operating in the stack. There are two different cranes
differentiated for the stack operations. The first one is the transfer
crane and the second is the straddle carrier. For both cranes the
scheduling problem has been investigated on two different parts. The
optimal configuration of containers in a stack is one part, while the
other part describes the optimal route through the stack.
