  • The main function of a container terminal is to load container freights into vessels and discharge them from vessels. The container terminal needs to utilize its resources effectively in order to improve the productivity of it. This study deals with the deployment model for yard cranes whose type is RMGC (rail mounted gantry crane). We develop a mathematical model for the deployment of yard cranes. The model considers not only the deployment but also the storage plans. It could be divided into two cases according to whether inter-block movements of yard cranes are allowed or not, during the same period Numerical examples are solved and analyzed to validate the model. Then, additional experiments are performed to compare the performance of the model with that of a previous model without the re-deployment of yard cranes.

  • At container terminals, a major measurement of productivity can be work efficiency. For improving the productivity of container crane, the more efficient container yard operation method is necessary in container terminals. Recently, container terminal operators make an experiment on the dual cycle operation, which ship loading/unloading were carried out simultaneously, for increasing the productivity of container crane. In this paper, propose a system operating efficient dual cycle methods as utilize Ad-hoc technology in distributed port operation system. The dual cycle methods that proposed recognizes position information of Y/T during an action in Ad-hoc networks in case of container transfer works by real time as load an Ad-hoc module to Y/T taking charge of a container transfer with quay and yard. Utilize Ad-hoc networks technology in an operating system of container yard, and efficiently distributed processing done Y/T to container crane compare with operation systems of the existing dedicated method, and an improvement can do an operating system of an yard.

  • Container terminals can maximize operational efficiency when appropriate berths (lengths) and yard capacity are secured. However, some container ports, such as Busan New Port, are separated and operated individually, which limits the efficiency of logistics. In this study, it was analyzed that the efficiency of the overall terminal operation (logistics) can be greatly improved when the yard co-petition area is used for two adjacent container terminals.

  • This paper deals with the development of simulation model for the container terminal consisting of 3 berths, 8 container cranes, 16 yard blocks with each yard cranes and 90 yard trucks in order to evaluate the various operational rules. The proposed operational rules are 3 ship dispatching rules, 3 berth allocation rules, 2 crane allocation rules, 2 yard allocation rules and 2 yard truck allocation rules and 4 performance measures like ship time in the terminal, ship time in the port, the number of ships processed and the number of containers handled are considered. The simulation result are as follows. 1) no difference among 3 ship dispatching rules, 2) berth allocation rules depends on performance measures 3) dynamic crane allocation is better than fixed policy 4) pooling yard allocation is better than short distance yard allocation rules and 5) fixed yard truck allocation by berth is a little better than pooling policy.

  • This Paper discusses how to estimate the container yard space of a port container terminal as well as how much the Inventory level of containers Is affected by related factors such as allowable dwell time for containers, handling volume per containership, and loading/unloading productivity of a port container terminal. Under the assumption of static relations among the factors, a model for estimating the container yard space is suggested. In terms of arrival patterns of containers, sub-models for export, import, and transshipment containers are constructed separately. A numerical example and the sensitivity analysis for some parameters are provided to help intuitive understanding the characteristics of the suggested model. The experimental results show that the allowable dwell time for containers is the most critical one of the factors to influence on the maximum Inventory level of containers.

  • Recently, container terminal managers make an experiment on the double cycle and dual cycle operation, which ship loading and unloading were carried out simultaneously, for increasing the productivity of quay side. If, however, we make an experiment on dual cycle operation in a real job site, the efficiency is poor up to terminal operation method as YTs(Yard Tractors)' allocation method, QCs(Quay Cranes)' working speed, and position of export containers. Especially, using the existing yard operation method, it is difficult to support to dual and double cycle operation. Therefore, this paper examine more efficient terminal operation method, when terminal uses dual cycle operation. We developed a simulation model using simulation analysis software, Arena.

  • The major movement block of the containers have range between apron and designation points on yard in container terminal. The yard tractor operated by human takes charge of its movement in conventional container terminal. In automated container terminal, AGV(Automated Guided Vehicle) has charge of the yard tractor's role and the navigation path is ordered from upper level control system. The automated container terminal facilities must have the docking system to guide landing line to have high speed travelling and precision positioning. The general method for docking system uses the vision system with CCD camera, infra red, and laser. This paper describes the detection of AGV's position and orientation using laser slit beam to develop docking system.

  • Because yard monitoring system is a part of real-time operation system and yard planning system, most planers, in container terminal, Busan Port, can not consider real-time and exact yard situation and container information such as position of equipments or movement of container with current planning system when export yard planning os established. Therefore, many planers recognize the limit of current planning system and try to find the solution to get over it. The reason of this, heuristic algorithms for the export yard the limit of current planning ,operating on monitoring system, are suggested and integrated export yard planning system is designed and developed in this paper.

  • This paper proposes a simulation model which evaluates operation plans of container terminal. The operation plans of container terminal consist of berth plan, load plan, unload plan, yard plan, and equipment plan. It is discussed how to apply the simulation method to evaluate those plans. Simulation analysis is based on data about plans from the operation planning system through an interface program. It is discussed what we should got in the simulation, for example, the statistics about container-handling equipment such as container cranes, transfer cranes, yard tractors, and trailers used in the transportation of containers.
