Vessel discharge and load jobs in a container terminal can be divided into sequences, one for each assigned quay crane (QC). A QC sequence lists containers in their desired handling order. The common practice for operators is to make do with just this sequence, without generating a job schedule (i.e. desired start-times of handling each container). Operators who need job schedules generate crud...

We consider the ship planning problem at maritime container terminals where containers are loaded onto and discharged from ships using quay cranes. The container transport between the ships and the yard positions in the terminal is carried out by a fleet of straddle carriers. Based on a stowage plan provided by the shipping company, the dispatcher assigns containers to specified bay positions. ...

In order to accommodate the growth in intercontinental container transport, port facilities have to be up-scaled drastically. One of the major challenges is to double the capacity of the marine operation on a container terminal. In this study the model of a quay transport system using automated guided vehicles (AGVs) is integrated with a detailed model of the container stack. The result is a ge...

In this paper an hybrid model for scheduling crane movements is presented. Cranes sharing the same track are considered. Cranes can reach any location along the track performing loading or unloading operations. As cranes share the same track their movements are constrained to avoid over crossing; tasks deadlines and priorities are also considered. Scheduler output are the assignment of the task...

The berth allocation problem (BAP), which de nes a processing interval and a berth at the quay wall for each ship to be (un-)loaded, is an essential decision problem for e ciently operating a container port. In this paper we integrate mobile quay walls into the BAP. Mobile quay walls are huge propelled oating platforms, which encase ships moored at the immobile quay and provide additional quay ...

The baseline plan of terminals will be impacted to a certain extent after being affected by uncertain events, such as vessel delay and unscheduled arrival, resulting in disorderly terminal operations, wasted resources, reduced loading unloading efficiency, which further aggravates congestion. To effectively cope with the disturbance operations above events improve operational efficiency contain...

This paper investigates cumulative scheduling in uncertain environments, using constraint programming. We present a new declarative characterization of robustness, which preserves solution quality. We highlight the significance of our framework on a crane assignment problem with business constraints.
