Since world container throughput continues to grow, the main issues facing decision-makers at port container terminals are how to expand the existing container terminals and construct new container terminals. Simulations can be used in the decision making process tools due to its ease and ability to reflect the real world system. The object-oriented approach provides for both reusability and modularity that best fits these requirements. In this paper, the object-oriented approach to modeling and simulating general container terminals is presented. Simulation tools based on Visual C++ provide a user-friendly input and output environment through the use of an object class-library. This paper also presents the case study of a simulation of a real container terminal in Pusan, Korea.

선박이 대형화되고 경제규모가 커지면서 선박의 화물운송 규모도 매우 커지고 있다. 이에 따라 컨테이너 터미널에서는 안벽하역 장비의 고속화, 대형화를 추진하고 있으며, 안벽의 고속 생산성은 한정된 규모의 장치장 점유율에 영향을 마치게 된다. 본 연구에서는 OHBC, RMGC, RTTC 등의 장비제원과 배치에 따른 장치장 점유율을 산정한다.

The maritime logistics environment including seaborne trade, shipping and ports is changing rapidly and continuously. Large containerships, mega carriers and global terminal operators try to achieve economies of scale and economies of scope. As a result of the changing environment, the competition between ports to achieve competitiveness is intensive. Port competition among China, Japan and Korea is becoming fiercer, both directly and indirectly, resulting from the increased trade in northeast Asia. Port development projects within each country stimulate more intensive port competition. As a result, overcapacity, fierce price competition and overlapping hinterland problems will be caused in the future. Co-operation for survival is considered as a strategy in order to solve anticipated problems caused by port competition Busan port, for instance, could co-operate with China and Japan as well as with other ports in Korea Terminal operators' expansion through investments including joint-ventures will make connections between ports smoother. At the port authority level, continuous cooperative interchange between countries is indispensable.

This paper suggests how can we guarantee terminal quality of service like ship waiting time ratio and ship residing time applying RFID(Radio Frequence IDentification) technology, raising up rapidly as a fundamental solution of new growing industry, to port information system. Also, lead time of whole port logistics can be decreased for reduction of loading & discharging time resulted from productivity improvement of G/C(Gantry Crane) and YT(Yard Tract) etc as applying RFID technology to terminal operation.

Container terminals in Northern Vietnam have recorded an impressive development in recent years. This development, however, also raises a fierce competition among local container terminals to attract customers. Beside the handling charges, the vessels' waiting cost is also an important factor that drive the opinion of users in choosing appropriate terminal. This research plans to estimate the waiting cost in different container terminals in Northern Vietnam by building regression equation that describe the relationship between the rate of throughput/capacity and waiting cost/TEU. Queuing theory with the application of Poisson distibution is used to estimate the waiting time of arrival vessels and uncertainty theory is applied to estimate the vessel's daily expenses. Previous studies suggested two different formation of the equation and according to the research results, cubic equation is more suitable in the given case. The research results are also useful for further research which require calculation of waiting cost per TEU in each container terminal in Northern Vietnam.

Due to the growth of container traffic and port competition, ports have increasingly been under pressure to improve their efficiency in port operation and port management for competitive edge. The purpose of this study is to compare the technical efficiency among major container terminals in China, Korea and Singapore using Data Envelopment Analysis (DEA). This paper analyses the returns-to-scale using the output orientation of VRS and CRS model. The benefits of this study examining the relative performance of container terminals will enable container terminal operating companies or port policy makers in those countries to identify current slacks and to set up a proper port management and operation plan to improve their productivity.

Port development has been remarkably increasing due to the progress of industrialization in ASEAN area. Especially, Vietnam has increased the international physical distribution in this area rapidly. The main issues facing decision makers at container terminals in Vietnam are how to expand the existing container terminals and construct new container terminals. In this paper, we performed the basic design based on simulation analysis in order to support the expansion of Quy Nhon port in Vietnam as a case study. The preliminary capacity analysis was conducted on the one berth at the port to analyze the scale of C/C(Container Crane)and yard area. Alternative scenarios were created based on the preliminary capacity analysis and the detailed simulation analysis was conducted for supporting the scenarios.

최근 심화되고 있는 컨테이너터미널 경쟁에서 각국 항만 및 터미널 운영업체는 터미널의 시설확충 뿐만 아니라 컨테이너터미널 효율성을 화물유치의 중요한 요인으로 인식하게 되었다. 이러찰 환경변화에 따라 컨테이너터미널의 효율성과 관련된 많은 연구가 수행되어 왔었다. 그러나 대부분의 기존 연구에서는 정성적인 설문조사나 기초데이터를 이용하여 컨테이너터미널에 대한 효율성을 부분적인 관점에서 분석하거나 단일 연도의 효율성 수준 및 자국 항만의 효율성만을 분석하였다. 따라서 본 연구에서는 확률프론티어 모형(Stochastic Frontier Model)을 이용하여 계량적이고, 패널자료를 사용하여 연도별 효율성의 변화를 실증적으로 분석하여 개별 터미널간의 효율성이 주는 시사점을 도출하였다. 우리나라 터미널의 효율성 수준은 해외 주요 터미널과 비교해본 결과 경쟁항만에 비해 감만터미널을 제외한 나머지 터미널은 낮은 수준으로 나타났다.

본 연구는 최근 우리나라 항만 물동량 증가세가 둔화되고 있는 가운데 국내 컨테이너터미널 운영기업의 경쟁력 강화를 위한 방안을 마련하고자 기업경쟁력 평가모형을 제시하고 글로벌 터미널 운영사와 비교분석하였다. 기업경쟁력 분석을 위한 퍼지모형은 퍼지이론과 AHP를 활용하였다. 경쟁력 평가를 위한 계층적 구조는 SERM 모형을 활용하였는바, 이는 기업의 성장이 주체(Subject), 환경(Environment), 자원(Resource), 그리고 메커니즘(Mechanism)의 상호작용 과정에서 형성된다는 논리에 바탕을 두고 있다. 분석결과 우리나라 컨테이너터미널 운영기업의 경쟁력은 글로벌 기업에 비해 전반적으로 약한 것으로 나타났다. 특히 기업의 대형화, 사업 다각화, 글로벌 전략수립이 시급한 것으로 나타났다.
