“…Therefore, we will consider, contrary to Imai et al (2007), the vessel operation time for a single ship as the main performance measure. Contrary to many other papers addressing terminal processes (e.g., Vis and Harika 2004;Nguyen and Kim 2007) we study self-lifting vehicles that both perform the transportation and storage processes (refer to the left side of Fig. 1).…”

The containerized trade market has been growing rapidly since its introduction. The capacity of ships and the amount of containers being transshipped at container terminals increases significantly. Terminals should handle their operations efficiently to provide the necessary capacity and customer service. In designing a container terminal, terminal management has to consider the choice for a certain type of berth. In this paper, we compare by means of a simulation study the performance of traditional one-sided marginal berths and indented berths. An indented berth enables quay cranes to unload and load containers from both sides of the ship. As a result, more quay cranes can work on a single ship. As main performance measure in this comparison we use the total vessel operation time required to unload and load a ship. This time depends next to crane productivity also on the efficiency of the transportation and storage and retrieval processes in the terminal. We have performed a sensitivity analysis in which we also study the relation between the selection of an indented berth and other design and control issues in the terminal.

“…A time axis is divided into multiple periods, each of which corresponds to a time interval between event times. Detailed explanations can be found in Nguyen and Kim (2009). However, some notations and modifications are needed to deal with the dispatching problem when considering multi-lifts by QCs.…”

Abstract.To improve the ship operation in automated container terminals, it is important to schedule different types of handling equipment to operate synchronously. For example, a vehicle with container receiving and lifting capabilities is used to transport containers from a storage yard to a vessel and vice versa, while a triple quay crane (QC) can handle up to three 40-ft containers simultaneously. This paper discusses the manner in which vehicles should be assigned to containers to support such multi-lifts of QCs by using information about the locations and times of deliveries. A mixed-integer programming model is introduced to optimally assign delivery tasks to vehicles. This model considers the constraint imposed by the limited buffer space under each QC. A procedure for converting buffer-space constraints into time window constraints and a heuristic algorithm for overcoming the excessive computational time required for solving the mathematical model are suggested. A numerical experiment is conducted to compare the objective values and computational times of the heuristic algorithm with those of the optimizing method to evaluate the performance of the heuristic algorithm.

“…Other works on dispatching different equipments at container terminals can be found in Bae (1999, 2004) for AGV dispatching problem while Kim and Bae (2004) employs a look-ahead strategy which considers local and temporal information of future tasks and assumes a dual cycle operations of AGVs; Nguyen and Kim (2009) extended Kim and Bae (2004) for automated lifting vehicles (ALV); Hartmann (2004) for a wider range of equipments; Narasimhan and Palekar (2002) in which every truck is dedicated to a particular quay crane as opposed to the approach in Kim and Bae (2004).…”

A new class of Intelligent and Autonomous Vehicles (IAVs) has been designed in the framework of Intelligent Transportation for Dynamic Environment (InTraDe) project funded by European Commission. These vehicles which are technologically superior to the existing Automated Guided Vehicles (AGV) in different technical aspects offer more flexibility and intelligence in manoeuver in the area where the logistics operations take place. This includes the ability of pairing/unpairing enabling a pair of 1-TEU (Twenty-foot Equivalent Unit) IAVs join and transport any size between a 1-TEU and a 1-FFE (Forty-foot Equivalent) containers. To accommodate this feature, in this article, we extend the classical mixed integer programming model of AGV scheduling in order to minimize the makespan of operations to transport a set of containers of different size between quay cranes and yard cranes. In particular, a case study on Dublin Ferryport Terminal is carried out. In order to cope with the complexity of the scheduling model, we design a Lagrangian decomposition approach utilized with variable fixing procedure and a primal solution heuristics to obtain high quality solution of instances of the problem.
