This paper considers the integrated problem of quay crane assignment, quay crane scheduling, yard location assignment, and vehicle dispatching operations at a container terminal. The main objective is to minimize vessel turnover times and maximize the terminal throughput, which are key economic drivers in terminal operations. Due to their computational complexities, these problems are not optim...

As more and more container terminals open up all over the world, competition for business is becoming very intense for container terminal operators. They are finding out that even to keep their existing Sea Line customers, they have to make them happy by offering higher quality service. The quality of service they can provide depends on their operating policies and the design of the terminal la...

in static scheduling problem, where there is no change in situation, the challenge is that the large problems can be solved in a short time. in this paper, the static scheduling problem of automated guided vehicles in container terminal is solved by the network simplex algorithm (nsa). the algorithm is based on graph model and their performances are at least 100 times faster than traditional si...

This paper has sorted out application and trend of Ambient Ubiquity Network, put forward the Network requirements construction principles for port digital twin applications combined with experience gained in process construction, provided overall framework universality, developed Exchange Software, conducted actual data access verification targeting at five-layer model based on micro-service te...

Procurement of electricity gains more and more focus in enterprises especially with the introduction of electric mobility. At a maritime container terminal the electricity consumption is highly related to the number of container movements of each day. Short-term load forecasting (STLF) methods have not yet been systematically researched when applied to container terminals. Therefore it seems re...

In this contribution we optimize the transportation of containers in the hinterland of a local area with one terminal and one depot for empty containers and trucks. There are several customers who want to receive goods by inbound containers and several customers who want to ship goods by outbound containers. Additionally, there are empty inbound containers and empty outbound containers. We pres...

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...

Container terminals play an important role in global cargo transportation and they have become an essential intermodal interface between the sea and the land. In the container terminal, the service area is often arranged into rectangular blocks, which leads to a mesh-like path topology. We present a mathematical model for general container routing in mesh yard layouts. Based on this model, a si...
