I try to introduce three types of designs for automatic container operating system which are designed by Institute of Japan Port Research in 1996. Each types are designedto fit with the situations of Japan Port. 'A'type of these designs adapts Dual Container Crane, AGV, RMG, etc. 'B'type of these designs adapts Dual Container Crane, AGV, OHBC, RTG. And 'C'type of these designs adapts Single Container Crane, AGV, OHBC, etc. Even if three designs are introduced, they have some problems to solve for the future. They are Lashing work, Refeer container problem, check for container and seal in main gate, Establishing EDI NETWORK, etc. I expect that this paper will be a helps to development of our port industry.

This study is to define the Automated Container Terminal(ACT) and container terminal system. Also, we analyze the present condition of the container terminal system in Pusan port and its automation level by systems approach. And this paper aims at evaluating on the priority of R&D investment until the beginning of the second stage of New Pusan Port Project(2006). In this process we have considered 8 factors (cost, labor, area, time volume, reliability, safety, convenience) to analyze 6 subsystems. The priority order of R&D until target year by sub-systems is as follow : Cargo Handling System〉Transfer System〉Port Entry System〉Storage System(Distribution&Manufacturing System included)〉Inland Transport System〉Port Information System.

A thematic land cover map of Pusan port area was developed using Landsat satellite TM(Thematic Mapper) image. Two types of digital data which are road and sea water layer are extracted from existing paper map were overlayed over the developed land cover map. SPIN-2(KNR-1000) image was utilized to make a facility map of JaSungDae port. SPIN-2 image, which has a cell resolution of 1.56 m showed higer accuracy than TM image, which has a cell resolution of 30 m for facility mapping. Overall, the techniques of digital mapping using satellite image are very useful, effective and efficient.

With such a analysis, the Korean ENC sea trial test plan is presented.

Simulation modeling has become an extremely important approach to analyzing complex system. In recent years the number of people using simulation as problem-solving aid has increased. In this Paper, we developed a simulation model for analyzing the physical distribution system in ports. we used Arena 2.2 which is a kind of simulation software based common simulation language, SIMAN V. And then, we applied this model to kwangyang port(partially) and analyzed the effect of it upon port system in according to change of the quantity of goods transported.

For the purpose of building the simulation model on cargo handling capacity of container terminal, we composed a model of container logistics system which has a 4 subsystems ; cargo handling, transportation, storage system and Gate complex system.

For the flexible and efficient application of the systems, we designed the systems with three modules such as "Define Module"."Simulation Module" and "Animation Module". "Animation Module".ule&".ot;.

Todays the efficient management of container has not been realized in container terminal, because of the excessive quantity of container transported and manual system. For the efficient and automated management of container in terminal, the automated container identifier recognition system in terminal is a significant problem. However, the identifier recognition rate is decreased owing to the difficulty of image preprocessing caused the refraction of container surface, the change of weather and the damaged identifier characters. Therefore, this paper proposes more accurate system for container identifier recognition as suggestion of Line-Scan Proper Region Detect for stronger preprocessing against external noisy element and Moment Back-Propagation Neural Network to recognize identifier.

This paper is aimed to handle quick work for all the workers and to improve the productivity by adding more effective content in Crane Monitoring System. This contributing proportion of the increase of port productivity is more increasing concerning not only the port industry, but also all the informations of container crane which is the representative equipment by the rapid increase of the volume of freight of port. The basic of rapid service is the improvement of the productivity, the information of operation as to the productivity of crane for the quick handling within yard and especially the informations of breakdown and to handle breakdown as soon as possible has a greate effect on the increase of productivity.

In this paper, we present a design of optimal 2-DOF PID controller for control of gantry crane which has to control swing motion and trolley position. For tuning the parameter of 2-DOF PID controller, we used evolution strategy(ES). During operate the crane system in yard, the goal is transporting the load to a goal position as quick as possible without rope oscillation. The crane is generally operated by an expert operator, but recently an automatic control system with high speed and rapid transportation is required. However, we developed an optimal controller which has to control the crane system with disturbance.

In this paper the sway-control problem of a container crane is investigated. The control loop is divided into two stages. The first stage is a modified time optimal control for trolley traversing. The velocity command for trolley traversing consists of three components ; a reference velocity and two feedback signals for compensating the deviations of trolley and sway angle from their desired trajectories. For trolley's exact positioning the trolley dynamics is identified via an error equation identifier structure. The second stage is a nonlinear residual sway control that starts at the end of first stage. The control design for the second stage is investigated from the perspective of controling an underactuated system, and the control law combines the feedback linearization and variable structure control.

Recently several researches of high speed container ship and loading system are mainly accomplished in U.S.A. and Japan. Its shipping service is not realized but it is realized in near future. To effective use of the feature and efficiency of them, quay, loading/unloading. yard operation system, port management system and connection transport system must be well integrated and operated. Specially, loading /unloading speed of container crane is important for making effective use of them. To speed up loading/unloading system, RO-RO and LO-LO methods that are mostly exclusive system are studied on the container crane with special structure and mechanism to handle individual container or bundle of containers. In this paper these methods are shown. When new high speed loading system of container is desighed, the realistic constrains must be considered.

In container crane system, the variation of cargo weight have effect on the travelling and sway control of load. For precise travelling and/or anti-sway control of crane system, the cargo weight should be measured and considered with control algorithm. But, and added attachment for measuring the cargo weight put restraint upon the control freedom for travelling and anti-sway. In this paper, we propose an estimation method for cargo weight in container crane system by using observation technique. First of all, we model the container crane system as a bilinear system and transform this model into linear system with external disturbance model. Second, we propose a generalized type - disturbance estimation observer and set a disturbance model, where, the cargo weight is related with the sway of load, and the sway is represented as a periodic external disturbance. Lastly, by using simulation we verify that the proposed algorithm of disturbance estimation observer is effective to estimate the cargo weight, and it will be used with anti-sway control algorithm.

A quartz crystal analyzer is utilized to monitor the cmsion process of an aluminum surface of a quartz crystal by sea water. A quartz crystal having 2000${\AA}$ of aluminum layer is installed in a spedally designed cell and is in contact with an electrolyte solution. While a constant potential is applied to the cell, the resonant frequency and resonant resistance are simultaneously measured using the quartz crystal analyzer. In addition, surface topographs are taken with an atomic force microscope(AFM) and the element analysis of the surface is conducted using an energy dispersive X-ray spectrornetedEDX). The simultaneous measurement of resonant frequency and resonant resistance during the corrosion process explains the change of surface structure caused by the corrosion. The variation of resonant frequency addresses the amount surface metal dissolution. As a conclusion, it is found that a simple measurement using the quartz crystal analyzer can replace the complex monitoring employing large equipments in the investigation of a corrosion process of metal surface.

Wave-induced current model is developed in our study and this model is composed with wave transform model and current model. Two types of wave model are used in our study, one is Copeland(1985) type which is applied in the offshore region and the other is Watanabe and Maruyama(1984) type which is applied in the surf zone. The depth-integrated and time-averaged governing equation of an unsteady nonlinear form is used in the wave induced current model. Lateral mising, radiation stresses, surface and bottom stresses are considered in our current model.

Numerical solutions are obtained by Leendertse scheme and compared with Noda's(1974) experimental results for the uniform slope coastal region test and Nishimura & Maruyama's(1985) experimental relults and numerical simulation results for the detached breakwater test. The results from our wave model show good agreement with the others and also show nonlinear effects around the detached breakwater. Wave induced current model is developed in this study and this model shows nonlinear effects around the detached breakwater and can be applied in the surf zone and also consider the friction stresses.

By the rapid expansion of containerization and intermodel transportation in international shipping since the 1970's, the larger containerships have emerged and concentrated their calls at a limitted number of ports. Moreover, large-scale container terminals have been built to accommodate the ever-larger containerships, and the mordernization of terminal facilities and many developments in information technology etc. have been brought out.

The forecasting of container cargo volumes should be estimated correctly because it has a key roles on the establishment of port development planning, and the decision of port operating system. Container cargo volumes have a dynamic characteristics which was changed by effect of competitive ports. Accordingly forecasting was needed overall approach about competitive port's development, alternation and information. But, until now, traffic forecasting was not executed according to competitive situation, and that was accomplished at the point of unit port. Generally, considering the competition situation, simulation method was desirable at forecasting because system's scale was increased, and the influence power was intensified. In this paper, considering this situation, the objectives can be outlined as follows. 1) Structural model constructs by System dynamics method. 2) Structural simulation model develops according to modelling of competitive situation by expended SD method which included HEP(Hierarchical Fuzzy Process) And actually, effectiveness was verified according to proposed model to major port in northeast asia.

This paper aims to suggest the strategies for Korea port, especially Busan to develope into a viable transhipment center and/or Hub port as the articulation points between mainline and feeder nets. To tackle this goal, the authors clarify the requirements for Korea port which will be critical in determining its position as Hub through the careful analysis on competitiveness, environmental impact, port policy and capacity, transhipment traffic and inherent ablity to generate traffic. The results are summerized as follows. (1) Coping with increasing container volumes, new investment is sustainedly necessary to increase the capacity and inherent ability of container port and create economies of scale. Moreover, increasing port capacity will increase the potential for the Korea port's inclusion into mainline rather than feeder networks. (2) Considering an increasing awareness of need for customer-oriented option s and service quality rather than simply a reliance on infrastructure-led efficiency, privatization of one sort or another and corporation of port have been key strategies in achieving greater efficiency in Korea containerport.

This paper deals with the problem of port administration and management of the port of Pusan. As the port of Pusan has been administrated by central government, Efficiency of port is worse than other foreign ports. These include the time-lagged port development, the inconsistent port planning with city planning, the insufficient long-term port development planning, the various operating authorities and the lack of port sales activities etc. To solve the above-mentioned problems, other superior ports are compared. The port Authority is proposed. It takes part in the long term port planning and the planning of financial provision. It designates and supervises the port manager, measures the result of port management and arranges the proposals. The port ownership transfer from Ministry of Maritime Affairs and Fisheries to Pusan Metropolitan. The port management is to be taken by the port authority and the port operation is to be performed by private companies. As a result, it is expected that port productivity increases and marketing power strengthens.

Delay time of receiving and delivery is one of important factors that should be considered in the evaluation of the customer service level of a container terminal. In this study, dispatching rules are tested with the objective of minimizing the service delay time for arriving outside trucks. A dynamic programming model is suggested for a static dispatching problem in which all the truck arrivals are known in advance. In order to overcome the excessive computational time of the dynamic programming technique, several heuristic rules are suggested that can be applied in practices. A simulation study is carried out to test the performances of the heuristic rules.

It is discussed how to route yard-side equipment during the loading operation in port container terminals.

The objective of the problem is to minimize the total container handling time in the yard. An encoding method to represent nodes in the search space is introduced utilizing inherent properties of the optimal solution by which the search space is greatly reduced. A beam search algorithm is suggested. A numerical experiment is carried out to compared the performance of the beam search algorithm with those of other approaches.

과거의 터미널은 사회 간접자본으로서 수출입 화물을 처리하는 항만의 기능을 중요시하여 왔다. 하지만 21세기를 맞이하는 지금에 와서는 고부가가치를 창출하여 내는 전략산업으로서 보다 많은 이익을 위해 터미널의 효율적인 운영을 필요로 한다. 그러므로 터미널 종합 관제 시스템은 보다 지능화 되어 터미널에서 발생하는 문제들에 시스템 스스로 이에 대한 해결책을 만들어 내고 이를 실제의 운영에 반영할 수 있도록 하여야 한다. 하지만 현재의 터미널에 도입되어 있는 시스템은 단순히 현재의 터미널 상황을 모니터링 하는 수준에 그치고 있다. 시스템에서 자동적으로 문제를 검출하고 해결하기보다는 어떤 문제가 발생하였을 시 문제가 생긴 상황을 파악하는 용도로서만 이용되고 있는 실정이다. 본 논문에서 기술하고자 하는 지능형 종합 관제 시스템은 이러한 용도를 넘어서 시스템 스스로 문제 상황을 파악하고 이에 대한 해결책을 시스템이 스스로 찾아내고 이를 직접 지시하여 터미널에 발생한 문제들을 해결하여 주는 시스템이다.
