Container terminals mainly include three types of handling equipment, i.e., quay cranes (QCs), internal trucks (ITs) and yard cranes (YCs). Due to high cost of the handling equipment, container terminals can hardly purchase additional handling equipment. Therefore, the reasonable scheduling of these handling equipment, especially coordinated scheduling of the three types of handling equipment, ...

Decision makers must face the dynamism and uncertainty of real-world environments when they need to solve the scheduling problems. Different incidences or breakdowns, for example, initial data could change or some resources could become unavailable, may eventually cause the infeasibility of the obtained schedule. To overcome this issue, a robust model and a proactive approach are presented for ...

Decision support systems and automated planning have become essential for the effective management of seaport container terminals. Due to ever-increasing levels maritime traffic freight transportation, terminals are expected facilitate their intra-yard operations while respecting tighter vessel schedules. Employed models must therefore be capable providing berth allocation decisions which not o...

Efficient management of port resources plays a crucial role in reducing vessel stay times and avoiding the payment demurrage charges. In this paper, we focus on integrated Laycan Berth Allocation Quay Crane Assignment Problem, which considers three main decision problems an way: dynamic continuous Problem time-invariant Problem. second part, problem is extended to Specific Assignment, includes ...

A U-shaped automated container terminal (ACT) has been proposed for the first time globally and adopted to construct Beibu Gulf Port ACT. In this ACT layout, double cantilevered rail crane (DCRC) simultaneously provides loading unloading services external trucks (ECTs) automatic guided vehicles (AGVs) entering yard. The DCRC a complex scheduling coupling relationship with AGV ECT, its mathemati...

This paper discusses the problem of scheduling quay cranes, the most important equipment in port terminals. A simulation model is developed for evaluating time of quay cranes. Then a dynamic scheduling model using objective programming for quay cranes is developed based on genetic algorithm approach. Finally, numerical experiments on a specific container terminal are made for propose approach. ...

Workers in ports work with and close proximity of heavy machinery. Quay cranes used for moving containers between ships the dockside yard are one most accident-prone equipment types. For picking up containers, these equipped spreaders, i.e. lifting devices which lowered down on top lock to them mechanically. We concerned here monitoring a quay crane spreader so as make sure that safe clearance ...
