This paper presents a method for designing layout on the yard and evaluating alternative designs of the layout by applying simulation. The method is based on the concepts of the conventional port container terminal with a perpendicular yard layout. In general, yard design of the container terminal is consists of the two major parts. One is to divide yard area between the number of sections and the number of runs and the other is to decide the number of equipment that is the yard truck and yard crane. In the past days, this design was depended on the experience of the terminal operator and the structure of the conventional terminal layout because it is a very complex decision problem. In this paper we suggest the method of yard design as a conceptual procedure and estimate the efficiency of the container crane and the optimal the number of equipment using the simulation. Numerical examples are provided in order to illustrate the conceptual procedure. As the example, the suggested method and simulation are applied to the virtual container terminal with a perpendicular yard layout. In the results, the number of sections and runs on yard area, the number of yard truck per container crane and the number of yard crane per run are decided. In additional, the traffic among blocks on yard layout is estimated in terms of rate.

본 연구는 시뮬레이션을 활용하여 장치장의 레이아웃을 설계하고 레이아웃의 대안설계를 평가하기 위한 방법을 제시한 다. 설계방법론은 장치장 레이아웃을 가진 재래식 컨테이너터미널의 개념들을 기초로 한다. 일반적으로 컨테이너터미널의 장치장 설계는 두가지 부분으로 구성되는데, 하나는 섹션수와 런수간의 장치장 면적을 분리하는 것이고, 다른 하나는 야드트럭과 야드크 레인과 같은 장비의 수찰 결정하는 것이다. 과거에는 이 설계가 매우 복잡한 문제이기 때문에 재래식 컨테이너터미널의 복제와 운영자의 경험에 의존했다. 본 논문에서는 개념설계로서 장치장 설계 방법을 제안하며, 시뮬레이션을 사용하여 컨테이너크레인의 효율과 장비의 최적대수를 추정한다. 실험결과로서 장치장 영역에서 섹션과 런의 수, 컨테이너 크레인당 야드트럭의 수, 런당 야드 크레인의 수 똥이 결정된다. 추가로 장치장 레이아웃에서 블록간의 통행량 흐름이 비율별로 추정된다.

The design of the container stacking yard influences significantly the productivity of handling operations in port container terminals. This study proposes methods for determining specifications of the yard considering the travel distance of vehicles and the storage capacity of yards. For a given length and width of a yard, it is discussed how to determine the layout and the dimension of yard blocks. The alternatives of the yard layout are evaluated by using a simulation study.

This thesis is to make it clear that simulacre concept of is an important factor that provides the motive to make spaces and to make it clear that yard in Korean traditional architecture has more meaning of a container that contains the simulacres of life than formal aspects. Namely, focusing on the simulacres, among existing important factors that cause changes in architectural spaces such as structure, function, beauty, I shall make it clear that simulacre concept, which is a creation thinking of post-structuralism philosopher, Deleuze, is a logic that builds and changes spaces. Also, the purpose of this research is to investigate successive circularity of yard spaces with the mutual relationship between simulacre concept that has virtual multiplicity and yard in Korean traditional architecture, a space of infinite emptiness. When certain simulacres occur in the yard, the ambivalence of simulacres provides meanings to yard by affiliating numerous simulacre factors, then by combination among those meanings, yard get mutual dependence. This is an important core point that I have focused on the beginning of this research. This research has found out the successive circularity of yard based on the relationship between simulacres and the essence of yard. The meaning of this research is to have found out that yard has the meaning of "a bowl that contains the simulacres of life," going over the simple meaning as a space between door and fence. Also, the simulacre concept is thought to be discussed as a motive for creation of various spaces from now on.

Purpose - Yard inventories increase when export containers are carried into the terminal and decrease when import containers are delivered to the consigners. The purpose of this study is to analyze container inventories according to the weekly ship arrival pattern at container terminals. Research design, data, and methodology - As container ships operate according to weekly schedules based on shipping companies and their routes, specific terminals provide a fixed-day service in a week. Thus, yard inventories can change with weekly fluctuations. The data used in this study were the actualdata at specific container terminals. Result - The dwell times of each container at a terminal represent an important variable that affectsyard inventories. Even cargo flows are steady in a given period, if dwell times are prolonged, yard inventories increase. Conclusion - Dwell time is another factor causing yard inventory change. Therefore, the calculation for yard inventories should consider the weekly ship arrival patterns and dwell times of each container. Further, at the planning stage, dwell time should be more carefully considered to calculate yard capacity.

The Internet has been developed interactive media for electronic commerce. This progress is affected by the growth and adoption of virtual community technology, real time dialogue, and video conference etc. Recently, 'blogs' are rapidly diffusing to personal media on the internet. In this paper, we first review the previous research relevant to 'blogs', and then analyze the business models for blog systems presented by previous researchers. We develop a yard-sale shopping mall on the basis of analysis, design, and implementation of blog application for e-commerce, using Mcrosoft ASP.Net. This article describes the yard-sale shopping mall on a blog, presents an example of its abilities, and describes planned future research.

항만 운영은 크게 게이트부문, 야드 부문, 선석 부문으로 구분되며, 이들 부문에 대한 운영전략과 효율적인 자원할당이 항만의 생산성향상에 중요한 역할을 한다. 특히, 선석 부문에서의 자원할당 계획은 선석 계획으로서 선박의 작업시간과 직결되기 때문에 최적화를 필요로 한다. 선석 계획은 독립적인 자원할당이 아니라 야드 부문의 장치 공간 할당과 상호 관련성을 가지고 있다. 따라서 기존 연구들이 선석 계획에 대해 독립적인 자원할당을 연구한 것과 달리 야드의 장치 공간 할당과 상호 관련성에 중점을 두고 선석 계획의 최적화 모듈을 설계하였다. 선석 계획 최적화 모듈의 설계는 수리적 기법으로 표현된 기존의 제약조건에 야드의 장치공간 할당과 관련된 제약조건을 제안하여, 해를 탐색하고, 찾은 해를 최적화하는데, 타부탐색을 사용하여 선석 계획 최적화 모듈을 설계하였다. 그리고 선석 계획 최적화 모듈의 성능 실험에서는 야드의 장치공간 할당계획을 적용한 선석 계획이 그렇지 않은 경우에 비해 작업시간이 단축됨을 알 수 있었다.

Cai-go management facility of harbor are required an expansion due to increase of cargo quantity. Design technology of Yard AGV call be possible to deal many cargo rapidly and accurately. So it is produced a profit about cal-go management. This study is presented optimum of suspension parameter for design technology Yard AGV. Model I, II are modeled about Initial of container weight, height. When the maximum stroke of suspension is 0.26m, optimum is achieved to reduce the reaction force at the minimum. Also, the reaction force is study to become stability in I second. A change of spring constant and coefficient of damper make change the reaction force and minimum reaction force appear in optimum value. All modeling and analysis are used combination. contact element of Ansys program.

In recent booming up of the ship building market, the supplying of large scale casting is difficult to keep the delivery schedule for ship yard because of the restrict manufacturer in Korea. And also, it is main cause to rise-up the cost of castings. This paper describes the outline of guidance of optimizing design for Rudder Horn Casting to reduce the risk of the delivery problem to ship yard.
