China has increased 10 percent every year since 1978. In particular, development and growth of Chinese ports make a remarkable in that the marine and coastal transportation handles the 90 percent of export-import cargo. This growth is beginning to threaten Korea's ports which are striving to become the hub of Northeast Asia logistics. Furthermore, the hub strategy of Northeast Asia is closely related to transshipment cargo invitation. The results of documents research indicate Busan and Gwangyang ports play an important role as an intermediate stopover between China and America. The ways to achieve transshipment cargo invitation are the construction of transshipment system based on the supply chain between korea and china, the maximization of trading volumes creation, equipment of ports infrastructure, and the constructions of the rail, road, coastal transportation infrastructures.

우리나라 수출입의 중요한 비중을 차지하는 동아시아 지역은 지리적, 정치적, 경제적, 사회 문화적 상호보완성으로 인해 더욱 증대될 것으로 예상된다. 최근 수출입 증대와 더불어 우리나라 항만과 대동아시아 국가간의 항만 물동량 역시 증가세를 유지하고 있다. 그러나 이들 국가의 경제 규모 및 성장율의 차이, 항만인프라 수준, 지리적 위치 등과 같은 다양한 요인으로 인해 이들 항만과의 물동량은 변동성을 보이고 있다. 항만 물동량의 변동성과 항만 네트워크의 변화에 대한 많은 연구에도 불구하고 우리나라 항만과 동아시아 항만과의 보다 세밀한 연구는 제한적이기 때문에 본 연구가 이러한 갭을 보충하고자 한다. 본 연구는 우리나라의 대동아시아 지역항만간 수출 컨테이너 화물의 유통경로의 추이를 분석하고, 이를 통해 우리나라 무역업체, 선사, 물류업체, 항만당국의 정책적 실무적 시사점을 제시하는데 목적이 있다. 2007~2015년간 우리나라의 주요항만과 대동아시아 개별항만간의 물동량의 변동성을 변이할당기법을 사용하여 분석을 진행한다. 분석결과 우리나라 항만 전체적으로 Shanghai, Ningbo, Ho Chi Minh, Haiphong 등이 규모와 물동량 증가면에서 가장 중요한 항으로 나타났다. 항만단위로 볼 때 부산항에서는 중국항의 경우 Yantai, Weihai, Hakata, Kobe, Ho Chi Minh, Haiphong, 인천항은 Lianyungang, Tianjin, Osaka, Kobe, Ho Chi Minh, Haiphong, 광양항은 Tianjinxingang, Weihai, Yokohama, Ho Chi Mihn, Tanjong, 울산항은 Yantai, Lianyungang, Nagoya, Kobe, Ho Chi Minh, Portkelang항과의 항만네트워크가 중요한 것으로 나타났다. 따라서 우리나라의 정부, 항만당국, 해운 물류업체들은 이들 항만과의 물류네트워크 협력을 강화하는 한편 이들 항만에 대한 투자를 적극적으로 추진해 나갈 필요가 있다.

전 세계 주요 선진 항만에서는 AI, 빅데이터, 자율주행자동차, 커넥티드카 등 4차 산업기술과 ICT 기술을 활용하여 항만의 효율성 증가, 항만 내 오염물질 배출 저간 등 환경규제에 대비하고 있다. 그리고 3D 업종 기피 등으로 인한 인력 감소의 문제를 해결하기 위해 완전무인자동화 터미널 개발에 투자하고 있다. 그러나 국내 항만에서는 선진 기술 도입이 늦어지고 있으며 그로 인한 항만 효율성이 떨어지고 있다. 또한 항만 안전사고 문제도 빈번하게 발생하여 항만 마케팅에도 심각한 영향을 미치고 있다. 이에 각 우리나라 컨테이너 터미널 별 특성과 유형을 분석하고 그에 맞는 자율협력주행 도입요인을 5개의 대분류 요인과 15개의 중분류 요인으로 분류하였다. 계층적으로 분류된 도입요인은 선사, 항만공사, 컨테이너 터미널, 관계 부처 등에 근무하는 종사자를 대상으로 설문 조사를 실시할 예정이다.

The rapid progress of the intermodal freight transportation in recent years has induced fierce competition among the adjacent hub ports for container transport. This brings increased attention to the evaluation of the port competitive ability. But it is not easy to evaluate the port competitive ability because this belongs to ill-defined system which is composed of ambiguous interacting attributes. Paying attention to this point, this paper deals the competitive ability of container port in Far-East Asia by fuzzy integral evaluation which is adequate to interacting ambiguous attribute problem. For this, the proposed fuzzy evaluation algorithm is applied to the real problem, based on the factors such as cargo volumes, costs, services, infrastructure and geographical sites These are extracted from the precedent study of port competitive ability, etc. The results show that the port evaluation factors come in following order ; services, costs, infrastructure, geographical sites and cargo volumes. There are some interactions(interaction coefficient, ${\lambda}=-0.664$ between evaluation attributes. The port competitive ability comes in following order : Singapore, Hongkong, Kobe, Kaoshiung and Busan. According to the sensitivity analysis, the rank between Busan and Kaoshiung changes when ${\lambda}=0.7$. From the analysis of the results, we confirmed that the proposed fuzzy evaluation algorithm is very effective in the complex-fuzzy problem which is composed of hierarchical structure with interacting attributes.

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.

최근 컨테이너항만은 서비스 차별화 전략을 통한 경쟁력 확보의 중요성이 커지고 있다. 서비스 차별화 전략은 기본적으로 고객의 요구사항에 대한 객관적인 평가가 필요하다. 이를 위해서 서비스의 품질을 측정할 수 있는 척도 및 방법을 개발하여야 한다. 본 연구에서는 부산항에 기항하는 주요 컨테이너 선사를 대상으로 연구를 수행하였다. 이에 따라, 선사가 컨테이너항만에 입항하여 출항하기까지 제공되는 서비스에 관한 측정항목을 도출하였다. 조사자료를 기반으로 탐색적 요인분석, 신뢰성 분석, 타당성 분석 등 개발된 정제과정을 통해 평가척도를 제시한다. 제시된 평가척도는 고객만족 및 기항의도와 높은 관련성을 보여주고 있으며, 향후 경영전략 수립에 유용할 것으로 기대된다.

Sea-ports in Northern Vietnam have experienced a rapid growth of container throughput in recent years. To accompany with such development, huge investment also has been performed to enhance not only local port capacity but also the regional logistics system. Container terminals in Northern Vietnam locate centrally along Cam river of Haiphong city, leaving 2 others in Quang Ninh province. Five out of totally 11 container terminals in the area are under the control of Vinalines - a national corporation in field of maritime industry. In this paper, those terminals are classified in terms of location and ownership. The volume of container throughput and facilities of all container terminals in Northern Vietnam from 2005 to 2014 are recorded in order to compare the performance of groups. A Data Envelopment Analysis (DEA) is then applied to evaluate the relative efficiency of such terminals. Before conclusion, number of suggestions will be contributed to related parties.

For the merit of a container in transportation and cargo handling the amount of container freight has been continuously on the increase. On the other hand container crane had got the bottle neck in cargo handling due to low productivity so that freight congestion had been often occurred at ports. in this paper A mathematical model for container crane system is represented a method for designing a fuzzy controller of container crane system for high productivity in cargo handling is presented. The fuzzy controller is compared with other optimal controller at the same condition. in the computer simulation the fuzzy controller obtained an excellent response to reference change better than the optimal controller. For disturbance such as a strong storm and parameter change due to change of cargo weight the result was also stable and robust than the optimal controller.

This paper addresses the design of container liner shipping service networks by explicitly taking into account empty container repositioning and container fleet size. Two key and interrelated issues of deployments of ships and containers are usually treated separately by most existing studies on shipping network design. In this paper, both issues are considered simultaneously. The problem is formulated as a two-stage problem: the upper-problem being formulated as a Knapsack problem and the lower-problem as a Flow problem. A genetic algorithm based heuristic is developed for the problem. Through a number of numerical experiments that were conducted it was shown that the problem considering empty container repositioning provides a more insightful solution than the one without.
