Although a number of container terminal simulators have been developed for various purposes, none of the existing simulators allow the system structure to reuse the system structure depending on application. Our goal is to develop highly reusable, highly inter-operable and flexible container terminal simulation system. The High Level Architecture(HLA) is an architecture for reuse and inter-operation of simulation. It is based on premise that no simulation can satisfy all use and users. An individual simulation or set of simulations developed for one purpose can be applied to another application under the HLA concept of the federation : a composable set of interacting simulations. The intent of the HLA is a structure which will support reuse of capabilities available in different simulations, ultimately reducing the cost and time required to create a synthetic environment for a new purpose, and the possibility of distributed collaborative development of complex simulation applications. In this paper, we discuss the design of a HLA-based port container terminal simulation system. Furthermore, we describe various technical motivations for HLA, the key elements of the architecture and how they are minimum and essential to the goal of reuse and interoperability.

In this study, we carried out a precedent investigation for an ultra-large container ship, which is expected to be a higher value-added vessel. We studied a preliminary optimized design technique for estimating the principal dimensions of an ultra-large container ship. Above all, we have developed optimized dimension estimation models to reduce the building costs and weight, using previous container ships in shipbuilding yards. We also applied a generalized estimation model to estimate the shipping service costs. A Genetic Algorithm, which utilized the RFR (required freight rate) of a container ship as a fitness value, was used in the optimization technique. We could handle uncertainties in the shipping service environment using a Monte-Carlo simulation. We used several processes to verify the estimated dimensions of an ultra-large container ship. We roughly determined the general arrangement of an ultra-large container ship up to 1500 TEU, the capacity check of loading containers, the weight estimation, and so on. Through these processes, we evaluated the possibility for the practical application of the preliminary design model.

An SADT-based methodology is presented for systematically analyzing the container working process in container terminal, as well as an object-oriented design method for an integrated information system for container terminal resource planning and management. Our design architecture is composed of four levels, activity interface, activity PDCA control, human resource management, and facility resource management. Especially, the consideration of the human resource management level makes it possible to support cooperative tasks, to make the authority and responsibility on a task clear, and to extremely promote the balance between human and facility resources. Finally, The system architecture is suggested for Virtual Container Terminal, in which a planned container working process is simulated for previous feasibility check, work orders are transferred to control real devices, and to manage the entire process and related data.

In the present study, the structural response of breakwaters installed on container carriers against green water impact loads was numerically investigated on the basis of the fluid-structure interaction analysis. A series of numerical studies is carried out to induce breakwater collapse under such conditions, whereby a widely accepted fluid-structure interaction analysis technique is adopted to realistically consider the phenomenon of green water impact loads. In addition, the structural behaviour of these breakwaters under green water impact loads is investigated simultaneously throughout the transient analysis. A verification study of the numerical results is performed using data from actual collapse incidents of breakwaters on container carriers. On the basis of the results of a series of numerical analyses, the pressure distribution of green water was accurately predicted with respect to wave mass and velocity. It is expected that the proposed analytical methodology and predicted pressure distribution could be used as a practical guideline for the design of breakwaters on container carriers.

In the case of railway freight, there's a lot of process at railway freight terminal. In these days, for operation efficiency improvement, Load/Unload planning is being carried out research. Load/unload problem can be classified as track assignment, container assignment, yard truck route problem, unload equipment scheduling, container yard plan. In this paper, we focus on track assignment and container assignment among the load/unload problem. we analysis information architecture to solve this problem. And we compares two precesses for existing method and optimization method of track/container assignment processes. An contents different analysis of two methods can shows reformation of an information architecture for load/unload process in the railway freight terminal.

To promote process effectiveness and efficiency, it is necessary that port logistics employ automated equipments for handling containers. There exists a system for automatically managing the container flow, called Control Module. However, it has limitation to assign the execution order to the machine and monitor the container flow in real time process. Business process management (BPM) provides a suitable and effective framework to address this problem including controlling and monitoring the flow of each container. Since the nature of container handling process is different with the common process in BPM that is conducted by human performer, it is necessary to adjust the BPM framework in the domain of port logistic management. This study presents a BPM framework corresponds with both human-based and machine-based activity to enhance the efficiency of port process flow including container flow. This framework is introduced as an integrated approach and mechanism of BPM application into the container handling system for the purpose of port logistics process automation.
