Japanese government has instituted and carried out Super-core Ports Policy to improve their operating efficiencies of international container ports from 2004. Despite of diverse institutional and administrative supports within this policy, this paper has assessed that they couldn't accomplished goals at the end of 2009 when the policy ended. In short, Japanese Super-core ports have explicitly lost the competitiveness for functioning as a hub-port in the East Asia region. We could find some defaults in the policy i.e. some limits of the private terminal operating units, inefficiencies in teaming between ports within Super-core port, lacking with system for collecting cargoes. In 2010, Japan is going to reinforce International Strategic Container Port Policy following Super-core Ports Policy. With this policy, they ought to prepare for the last leap on the basis of selection and concentration rules in international port. This new policy is particularly focused on recapturing their T/S cargo via Busan port. Regarding these changes, Busan port needs to prepare counter measurements for preserving Japanese T/S cargo firmly.

The coastal shipping transport for containers had been serviced by Hanjin Transpotation Co., Ltd. and Korea Express Co., Ltd. from 1995. But Korea Express Co., Ltd. and Hanjin Transpotation Co., Ltd had stopped a coastal shipping transport service routed Busan-Incheon bemuse of getting worse of operation balance in 1999 and 2006 respectively. As a result of these situations, korean-flag and foreign-flag fleets are having difficulty in handling T/S cargos and in-time transport service among inter-ports in korea. As shippers also use lorry to transport their cargos than using costal shipping, it occurs increasing in national logistics' cost as well as time-consuming due to congestion on the road. Therefore, this paper identifies not anly current costal shipping transport systems but also those problems and analyses a economic effect in case of participation in the costal shipping transport service by foreign-flag vessel using monte carlo simulation.

Logistics needs in Asia are surprisingly increasing due to rapid growth of China Therefore, each country is trying to develop ports in order to attract logistics needs. Korea, also, begins to perform active port marketing policy, centering around Busan port and Kwangyang port, in order to become a logistics hub in Northeast Asia Recently, competitiveness of Japan has decreased due to increase in the inland transport costs, so Japanese is deliberating various counter plans. While Japan is stagnant, Korea has an opportunity for activating Busan port and Kwangyang port. This study estimates logistics costs by classifying types of delivery routes of Japanese imports and exports containers; that is, by dividing the case of using main ports in Japan, or Busan port and Kwangyang port. As a result, logistics costs are greatly reduced when the containers go by way of Busan port and Kwangyang port social and logistics costs.

Busan Port has been facing critical situation in terms of container handling volume, especially growth rate of transshipment(T/S) container of the year of 2006 was at a standstill. Annual average growth rate of T/S container during the period of 2003 to 2006 slowed down to 7.7% while it recorded over 34% to the period of 1999 to 2002. It has mainly resulted from the change of circumstance of Northeast Asian ports, that is, firstly mega carriers' increasing direct call to Northern Chinese ports such as Qingdao, Tianjin and Dairen effected to T/S container volume of Busan port, secondly start to operate deep-water port of Shanghai, thirdly Japanese super hub port project to handle their local containers at domestic ports. This paper aims to analyze the T/S type of inter-routes and hub and spoke and statistical status of Busan port. The purpose of the paper is to propose new concept which is to attract T/S container utilizing hub port function of Busan port in Northeast Asia It is that mega carriers are given dedicated terminals to use Busan port as T/S base in the region.

Hub-and-spokes전략은 교통분야에서 널리 이용되는 네트워크전략이지만, 철도의 경우 대개 이 전략을 이용하기 어려운 네트워크구조를 가지고 있어 그 적용사례를 찾아보기 어렵다. 그러나 유럽에서는 철도망이 도로망처럼 조밀하게 형성되어 있다는 점과 환적 처리기술의 발달로 90년대 초부터 이 전략이 철도화물운송부문에도 도입되기 시작했다. 이러한 관점에서 본 논문은 철도화물운송망에서의 hub-and-spokes전략을 구현하는 서비스네트워크 디자인모형을 개발하고, 모델의 실제철도망에의 적용성을 평가한다. 개발되는 모형이 전략모형임에도 불구하고 모형에서는 일반화된 운영비용 외에 열차속도, 서비스빈도, 터미널에서의 화물처리속도 등에 따른 시간지체비용도 고려되었다. 시간지체비용의 고려에 따라 야기되는 비선형 목적함수는 빈도별 서비스결정변수의 설정을 통해 선형화되어 결과적으로 모형은 선형 binary정수 최적화문제로 표현되었다. 규모가 큰 네트워크의 경우 해도출의 어려움 때문에 본 논문은 전체문제의 분할(decomposition)에 기초한 휴리스틱방법((heuristic method)으로 해결한다. 해도출의 효율성을 높이기 위해 서비스빈도개선과 관련하여 세 알고리즘이 개발되었다. 개발된 알고리즘은 유럽의 실제네트워크를 기초로 도출한 4개의 테스트문제에 적용되어, 해의 정확도와 해 도출의 효율성이 비교·평가되었다.

This study intends to verify the effectiveness of incentive schemes at Busan Port' aimed at promoting transshipment cargo. The current incentive schemes of Busan port intended to increase the T/S cargo volume have been disputed constantly. It is imperative, therefore, to restructure the system in accordance with the planned strategy. In this study, in order to ensure objectivity of the incentive schemes, all the parties (carriers, terminal operators and Port Authority) with a direct interest are answered and analyzed using the AHP methodology. Effectiveness is the top priority in the analysis of beneficiary validity of incentive schemes, when incentives are provided to Global overseas carriers compared with Global national carriers, IntraAsia carriers and Terminal operators. In the analysis of incentive schemes, direct cash support corresponding to the quantity of the T/S cargo had the highest effectiveness compared with exemption of port dues, cost compensation, port infrastructure support and subsidy for the service opening. The study results, therefore, reference the Port Authority when restructuring the schemes. This study has been conducted only focusing on the Busan port; however, the findings may have significant implications for overseas Port Authorities intending to implement incentive systems to promote cargo volumes similar to those at Busan port.

The explosion of a chemical tanker ship during cargo transshipment via double-banking at Ulsan Port, resulted in major damage including fires involving nearby ships. As a follow-up measure to prevent the recurrence of similar accidents, the 'Safety Management of Dangerous Goods in Port' was established, and the designation of a transshipment pier for dangerous goods is required given the risk of explosion and the impact on major facilities in the port. This study evaluated the Fire & Explosion Index of major transshipment cargoes in Ulsan Port to design a transshipment pier based on the Explosion Risk Assessment. Based on the results of Fire & Explosion Index evaluation of styrene monomer and benzene, severe explosion risk was confirmed, and the exposure radius was calculated. Based on the results of the exposure radius, the risk range for each major pier was calculated, and 12 terminals were proposed as transshipment pier candidates considering port facilities, surrounding dangerous facilities, and residential aspects. Since the results of the study suggest transshipment piers based on the risk radius alone, maritime traffic safety, pier and mooring facilities, safety facilities and accessibility for emergency response should be considered comprehensively to designate actual transshipment piers.
