As the environment surrounding ports is rapidly changing and ports competition in Southeast Asia has become more severe to secure cargo volumes, ports strive to enhance their competitiveness by improving the efficiency of operations. The operational efficiency of ports, plays a crucial role to improve a nation's. This study aims to analyze the efficiency of container port and its determinants during over five year(2006 to 2010) period using DEA-O and Tobit regression respectively. The results show that firstly, Gamman is the most efficient container terminal, followed by New Gamman container terminal and Hutchison Busan container terminal. Secondly, it is notable that the efficiency of Busan Newport is dramatically increasing, and finally, the yard productivity of the container port is only influencing determinant of all.

The port industry is an important national industry which significantly affects Korea's imports and exports which are centered on economic structure. For instance, the Port of Busan, which handles 75% of domestic container freight volume, is expected to become increasingly critical for container liner routes. For this reason, there have been continued efforts to expand freight service to attract international freight volume. This study analyzes the structural characteristics of the port network connected to the Port of Busan by analyzing the pattern of the container liner route from 2012 to 2016 by using social network analysis. According to the Port of Busan's liner route network, the port with the highest degree of centrality, closeness centrality, and betweenness centrality was found to be the Port of Singapore. The comparison of Busan's annual container handling rank by countries and the port center network analysis of Port of Busan rank was found to be different. As a result, it was established that China's East Port, which occupies a high percentage of the volume of cargo handled by Port of Busan, is not a hub port of Busan when viewed on the Busan's container terminal liner network. In addition, even if the number of Port of Busan container liner service increases, it is estimated that the vessels to be added to the fleet will be limited to small to medium sized, or that Busan port has characteristic of a feeder port for the Port of Singapore, according to the network.

항만물류산업은 서비스가 무형적이며 생산과 동시에 판매되어 소비되는 즉시성 및 비저장적인 특성으로 인해 정보의 이용, 관리 및 흐름이 중요하다. 최근의 정보통신기술의 발전은 정보의 이용 및 흐름을 위해 여러 가지 기술들을 등장시키고 있으나, 항만물류산업은 공공성이 강하여 여러가지 제약이 따르는 제약성, 해상운송선박의 불규칙한 입출항 패턴과 관련한 불규칙성, 노동집약적인 특성으로 인해 적극적으로 도입이 되지 못하고 있는 실정이다. 따라서, 디지털 경제의 확산에 따라 변화하는 환경에 적극적으로 적응, 대처하기 위해 항만물류산업의 정보화 및 e-비즈니스 도입을 가속화하며, 최근 B2B 전자상거래 프레임워크로 전세계적인 표준으로 자리잡고 있는 ebXML을 항만물류산업에 적용하여 항만물류산업에서 e-비즈니스를 원활히 수행하기 위한 기술적, 관리적, 제도적 전략 계획이 수립되어 할 것이다. 본 연구는 우리나라 국가표준으로 채택된 ebXML을 항만물류산업에 선도적으로 도입하기 위한 연구로서 항만물류산업의 환경 및 현황을 분석하고 ebXML을 항만물류산업에 효과적으로 적용하기 위한 목표모델을 설계하며, 아울러 실행전략을 수립하였다.

The purpose of this study is to suggest a major strategy to become effective for each port in Northeast Asia by analyzing the relative efficiency of each port to determine the current level of efficiency, efficient harbors plan. Individual port of the major 16 ports in Northeast Asia was analysed targeting efficiency and relative efficiency. In this study, DEA technique was used. Of the DEA model, CCR (constant returns to scale) models and BCC (variable return to scale) model was applied to analyze the efficiency and effectiveness of the port. Then the efficiency measured through CCR model is again compared with the efficiency measured by the BCC model. In this way, the empirical analysis includes the input factors of the operating ports such as the number of berths, wharf, depth, total area of the pier, C / C numbers and output elements includes the container throughput. The results of the study show that most of the ports in China is efficient whereas those in Korea and Japan are relatively inefficient. There are some pairs of ports which has the similar input factors, like Busan port and Shanghai port, Lianyungang port and Incheon port, Dalian port and Gwangyang port, but the container throughput of them has a huge difference.

This paper aims to implement an empirical research about the efficiency of America and Northeast Asia pots, and to suggest an effective strategy which can operate these ports more well. This study tries to apply the Data Envelopment Analysis(DEA) model to America and Northeast Asia ports. DEA is a methodology of comparing the relative efficiency of each decision making unit(DMU) by comparing it with other DMUs having similar input and output structure, and is specially very useful when a form of production function of each DMU such as a port is not known. DEA provides the extent of inefficiency of DMUs, which is practically useful information (like the efficiency score and reference sets) required to improve efficiency. This paper analyzed the relative efficiency of 35 ports in America and Northeast Asia for 3 years from 2005 to 2007 through DEA-CCR, DEA-BCC model and scale efficiency. Accordingly, this paper evaluates the efficiency of America and Northeast Asia ports, grasps the position at the present time, and suggests an advanced direction in future.

The purpose of this paper is to show the clustering trend and the comparison of empirical results and is to choose the clustering ports for 3 Korean ports(Busan, Incheon and Gwangyang Ports) by using the bootstrapped DEA(Data Envelopment Analysis) and game Cross-efficiency models for 38 Asian ports during the period 2003-2013 with 4 input variables(birth length, depth, total area, and number of cranes) and 1 output variable(container TEU). The main empirical results of this paper are as follows. First, bootstrapped DEA efficiency of SW and LT is 0.7660, 0.7341 respectively. Clustering results of the bootstrapped DEA analysis show that 3 Korean ports [ Busan (6.46%), Incheon (3.92%), and Gwangyang (2.78%)] can increase the efficiency in the SW model, but the LT model shows clustering values of -1.86%, -0.124%, and 2.11% for Busan, Gwangyang, and Incheon respectively. Second, the game cross-efficiency model suggests that Korean ports should be clustered with Hong Kong, Shanghi, Guangzhou, Ningbo, Port Klang, Singapore, Kaosiung, Keelong, and Bangkok ports. This clustering enhances the efficiency of Gwangyang by 0.131%, and decreases that of Busan by-1.08%, and that of Incheon by -0.009%. Third, the efficiency ranking comparison between the two models using the Wilcoxon Signed-rank Test was matched with the average level of SW (72.83 %) and LT (68.91%). The policy implication of this paper is that Korean port policy planners should introduce the bootstrapped DEA, and game cross-efficiency models when clustering is needed among Asian ports for enhancing the efficiency of inputs and outputs. Also, the results of SWOT(Strength, Weakness, Opportunity, and Threat) analysis among the clustering ports should be considered.

This research attempts to explore the competitive advantage of the Busan New Port based on the comparative analysis against the major ports. The competitive environment of the global shipping business poses a variety of challenges for the port authorities. Pursuing the hub position in the Northeast Asia, Busan new port needs an in-depth competitive analysis against the major ports in Singapore and China. This research proposes the strategies to exploit the locational advantage of the port while upgrading the operational efficiency. The recent development of the information technology suggests a viable solution for the Busan port.

In order to effectively operate and manage the port terminal, it is necessary to use port terminal simulator for the analysis of port terminal. However, there are many difficulties in applying an existing port terminal simulator to various terminals, because each of the port terminals has different structures, facilities, equipment, and job processes. Therefore, in this paper, we propose a design method of port terminal simulator for the improvement of reusability by using model-based techniques. We also showed the implementation of the prototype of the port terminal simulator of applying the research content.
