In automated container terminals, containers are transported from the marshalling yard to a ship and vice versa by automated vehicles. The automated vehicle type studied in this paper is an automated lifting vehicle (ALV) that is capable of lifting a container from the ground by itself. This study discusses how to dispatch ALVs by utilizing information about pickup and delivery locations and ti...

This paper presents an efficient and robust parameter training methodology, based on a previous approach for inverse building modeling that utilizes a simplified state-space approach. One new element of this training methodology is that some seasonal effects, such as variation of window transmittance at different times of the year, are taken into consideration and captured during the training p...

Globally, container terminals are trying to expand capacity and increase performance at a minimum of investments. Often the container terminal operations are changing to meet increased customer demands as well as to adapt to new technologies. This paper proposes a simulation model for container terminal system analysis. A simulation model is developed, called SIMPORT, which uses a Multi-Agents ...

This section contains an overview of the different functional areas of a marine container terminal and a summary of the main types of container handling systems. The main advantages and disadvantages of each type of handling system are also summarized without focusing on technical details. 2.1 Functional Areas of Terminal Operations As every other terminal, a container terminal is a complex sys...

This study is motivated by the practice of large iron and steel companies, which have steady and heavy demands for bulk raw materials such as iron ore, coal, limestone and so on. These materials are usually transported to a bulk cargo terminal by ships (or to a station by trains). Once discharged, they are moved to and stored in bulk material stock yard, waiting for retrieval for production use...

In this paper we present a discrete event simulation model to approach the decision problems arising from an expansion plan of a marine container terminal. In particular the preliminary study herein presented starts from a collaboration with the Southern European Container Hub (SECH) sited in the Port of Genoa, Italy. The planned expansion will take place from 2010, the terminal area will enlar...

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...

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. ...

Railway yard is the basic composition unit of railways, therefore, the efficiency and quality of railway yard design have a crucial effect on the construction and operation of railways. Plane design is the basis and core of railway yard design, consequently, it is significant to research plane design of railway yard. In this study, through analysis and summary of the research status as well as ...
