We study the coordinated scheduling problem of hybrid batch production on a single batching machine and two-stage transportation connecting the production, where there is a crane available in the first-stage transportation that transports jobs from the warehouse to the machine and there is a vehicle available in the second-stage transportation to deliver jobs from the machine to the customer. A...
Over the last years, international sea freight container transportation has grown dramatically and container terminals play nowadays a key role within the global shipping network. Terminal’s operations have received increasing interest in the scientific literature and operations research techniques are more and more used to improve efficiency and productivity. In this work we provide an overvie...
In container terminals, one of the most important factors driving the logistic efficiency in the yard is stowage planning for containers designated to be exported. The stowage plan and operations have to meet the requirement of the liner shipping company of ship stability on the one hand, and to ensure the smooth and orderly process of handling containers, deployment and movement of the yard cr...
Crane sequencing in container terminals determines the order of ship discharging and loading jobs that quay cranes (QCs) perform so that the duration of vessels’ stay is minimized. The ship’s load profile, berthing time, number of available bays and QCs are considered. More importantly, clearance and yard congestion constraints need to be included, which respectively ensure that a minimum dista...
Seaport container terminals are source of many interesting large-scale optimization problems, which arise in the management of operations at several decision levels. In this paper we firstly illustrate a recently proposed framework, called two-stage column generation (Salani and Vacca, 2008), which is suitable for a particular class of large-scale problems, where the structure of the original f...
The existing research about multi-agent systems (MAS) in container terminal have not yet fully depicted the entire operations processes. These past works tend to use static (linear programming-based) modeling methods model systems. This method has a weakness because decision optimality is only guaranteed for agents that are directly involved discussion. While other whose performance affected by...
The handling of containers in port logistics consists of several activities, such as discharging, loading, gate-in and gate-out, among others. These activities are carried out using various equipment including quay cranes, yard cranes, trucks, and other related machinery. The high inter-dependency among activities and equipment on various factors often puts successive activities off schedule in...
The berth-allocation problem (BAP) aims to optimally schedule and assign vessels to berthing areas along a quay. The vessels arrive at the port over a period of time and normally request service and departure within a time window. These time windows are usually determined through contractual agreements between the port operator and the carrier, in terms of time of departure after the vessel’s a...
Management of container terminal operations is essentially the allocation and scheduling of the expensive resources such as berths, quay cranes, storage space, yard cranes, and container carriers. Each of these resources plays an indispensable role in the interlocking processes in a container terminal. In this survey we give a critical review and a comparative study on various decision problems...
An overview of literature is conducted on research focusing on improving the performance of container terminals. The growth of containerization has led to numerous decision problems for container terminal management to consider in operating their container terminals more efficiently, e.g. where to place a ship along a quay, scheduling the resources to work a ship, etc. The research papers revie...
