In a container terminal, containers unloaded from a ship are moved to the yard during the import operation. The export operation is the reverse of the import process. When a ship is served by multiple shore-cranes having both loading and unloading activities at the same time, a yard-machine can process an import container and an export container in one single round-trip. This paper investigates...

The operational performance of container ports has received more and more attentions in both academic and practitioner circles, the performance evaluation and process improvement of container ports have also been the focus of several studies. In this paper, Data Envelopment Analysis (DEA), an effective tool for relative efficiency assessment, is utilized for measuring the performances and bench...

The efficiency of a maritime container terminal primarily depends on the smooth and orderly process of handling containers, especially during the ship's loading process. The stowage and associated loading plans are mainly determined by two criteria: ship stability and the minimum number of container rehandles required. The latter is based on the fact that most container ships have a cellular st...

In the last four decades the container, as an essential part of a unit-load-concept, has scored a great success in international sea freight transportation. With increasing containerization the number of seaport container terminals and competition has increased considerably. One of the success factors of a terminal is related to the time in port for container vessels and the transshipment rates...

In the process of automatic container terminal loading and unloading, three-dimensional attitude affects security unloading operations, so positioning is very important. this paper, a visual non-contact measurement method used to realize real-time orientation container. First, corner coarsely positioned by small-scale deep learning network. Secondly, precise position keyhole obtained secondary ...

The motivation for this thesis resulted from a study of semi-automated rail mounted gantry cranes at an Australian seaport container terminal. The Sequential Ordering Problem with Time Windows (SOP-TW) can arise as a subproblem of these crane operations. The SOP-TW corresponds to the task of scheduling a single crane to move a set of containers, where each container has: a fixed pick-up locatio...

Hinterland transportation has become increasingly critical for global container supply chain performance. However, the literature on the management of the container supply chain tends to overlook the issues related to hinterland transportation. The problem we consider here is faced by a deep-sea terminal operator who wants to open an inland terminal to facilitate its operations. When developed ...

Continuously increasing global container trade and pressure from a limited number of large shipping companies are enforcing the need for efficient container terminals. By using internal material handling resources efficiently, transfer times and operating costs are reduced. We focus our study on container terminals using straddle carriers for transportation and storage operations. We assume tha...
