  • This paper aims to determining the optimal capacity of Pusan port in view point of Container Physical Distribution cost. It has been established a coast model of the container physical distribution system in Pusan port is composed of 4 sub-systems and in-land transport system. Cargo handling system, transfer & storage system and in-land transport system, and analyzed the cost model of the system. From this analysis, we found that the system had 7 routes including in-land transport by rail or road and coastal transport by feeder ship between Pusan port and cargo owner's door. Though railway transport cost was relatively cheap, but, it was limited to choose railway transport routes due to the introducing of transport cargo allocation practice caused by shortage of railway transport capacity. The physical distribution ost for total import & export container through Pusan port was composed of 4.47% in port entring cost, 12.98% in cargo handling cost, 7.44% in transfer & storage cost and 75.11% in in-land transport cost. Investigation in case of BCTOC verified the results as follows. 1) The optimal level of one time cargo handling was verified 236VAN (377TEU) and annual optimal handling capacity was calculated in 516, 840VAN(826, 944TEU) where berth occupancy is $\rho$=0.6 when regardless of port congestion cost, 2) The optimal level of one time cargo handling was verified 252VAN (403TEU) and annual optimal handling capacity was calculated in 502, 110VAN (803, 376TEU) where berth occupancy is $\rho$=0.58 when considering of port congestion cost.

  • An environment of world marine port today is rapidly changing. Importance of a hub port is being maximized along with appearance of a large container ship, and Busan port is also growing with the goal as a hub port of Northeast Asia. Busan port currently has competitive power as the 5th top port in the world, but increase rate of transportation quantity, is low compared to Shanghai port in China and other ports in Northeast Asia. For a port to obtain competitiveness, investment on infrastructures of a port is necessary and also it has close relation with an intraregional port logistics industry. However, a port logistics industry in Busan area has a hard time avoiding a small size due to the government support on major companies. Therefore, this study will analyze difficulties of small port logistics companies and the related companies as to vitalize port logistics industry in Busan area in hopes to help vitalizing regional economy.

  • 본 논문의 핵심은 일정한 전용항만을 운용하는데 있어 발생되는 물유비용을 크게 3가지로 나누어 이들의 합계가 최소화 될 수 있는 선박톤수 별 연간 발주 항차 수를 최적화하는 것이다. 즉 항만에서 적항과 양항간을 오가며 발생되는 해상수송비용, 도착 선박이 항만에서 선석을 기다리며 발생되는 대기비용, 그리고 수입된 화물이 하역되어 야적장에 보관된 상태에서 발생되는 재고유지비용 등의 비용발생 행태가 대, 중, 소 3가지 선급별 연간 항차 수의 배정에 따라 상이한 만큼, 이들 비용의 합계가 최소화 될 수 있는 최적 항차 배정 의사결정이 요구된다. 이때 해상수송비용은 주어진 선급 별, 항만 별 요율로써 확정할 수 있고, 항만 대기비용은 시뮬레이션 모델로써 추정할 수 있다. 그리고 야적장의 화물 재고유지비용은 연간 평균재고량에 화물 별 단가(單價)와 이자율 등을 감안하여 추정할 수 있다. 포항제철(주)의 원료수입 전용부두를 운영하는 사례 분석 결과에서 규모의 경제 효과에 의한 해상수송비용을 최소화하기 위해 대형선박의 연간 항차 배정 율을 증가시킬 경우, 일정 비율을 지나면 선박 대기비용이 급격히 상승하고 야적장의 재고비용도 다소 상승되어 결국 총비용이 증가하는 것으로 나타났다. 따라서 현재의 전용항만 구조하에서 물류비용을 최소화하기 위해서는 중형선은 연간 총 배정 항차 수의 약 50% 정도의 비중으로, 대형선은 약 33% 정도, 그리고 소형선은 약 17% 내외로 구성하는 것이 최적인 것으로 나타났다. 물론 이러한 분석 결과는 추후 새로운 선석의 건설, 수입화종과 화물량, 단가 등의 변수에 따라 달라질 수 있다.

  • 본 연구에는 국제무역이론에서 자주 이용되고 있는 중력모형을 이용하여 시계열 분석에서 고려되지 못한 항만입지(주간선항로상의 위치여부), 항만비용(해상운송비용), 지역경제협력(ASEAN, EU, NAFTA) 등을 시계열 자료와 결합하여 부산항의 해상물동량을 추정하였다. 부산항의 수출입물동량에 대한 분석 결과를 살펴보면, 두 나라간의 거리에 (-) 영향을 받고, 우리나라와 교역상대국 GDP의 합에 대해서는 (+) 효과를 나타내는 것으로 분석되었다. 교역상대국이 주 간선항로 위치 여부(LINE)와 해운협정 체결(ARG) 여부는 (+) 부호를 나타내며 통계적으로 유의한 결과를 얻었다. 해상운송비용의 경우는 해상운임이 1% 포인트 상승하면 부산항의 수출입물동량은 0.323에서 0.490% 정도 감소하는 것으로 분석되었다. 부산항의 입출항 환적물동량에 대한 분석 결과, 우리나라와 교역상대국 GDP의 합은 (+)의 호과를 나타내는 것으로 분석되었으며 주간선항로의 위치변수(LINE)는 (+)의 부호를 나타내고 통계적으로도 유의한 것으로 나타났다. 해상운송비용은 1% 포인트 상승하면 부산항의 환적 물동량이 약 0.586에서 0.895 가량 감소하는 것으로 분석되었다. 지역경제협력체인 EU에 대해서는 수출입과 환적물동량 모두에서 (-)의 부호를 나타내었고 ASEAN은 환적물동량에서 (+)의 부호를 나타내며 통계적으로 유의한 결과를 얻었다.

  • In this study, to identify the ineffectiveness of inter-connected system of cargo volume between the Pusan Port and inland areas and also to make more rational suggestions, the following conclusions were drawn by analyzing Container Cargo Traffic from BCTOC to Off-Dock CY: 1. There existed about 30% to 50% reduction in the container transport times when the container transport vehicles were operated during the off-peak period to alleviate the traffic congestion due to mixed traffic. 2. There appeared to be more economic when Off-Dock DY's scattered around the City of Pusan were unified in one ODCY Unit at YangSan, and the Exclusive Overpass Freeway System for the container transport vehicles were constructed and operated on the existing Urban Freeway from BCTOC ti this ODCY Unit (Expected to make about 230 billions Won in net present value by NPV method).

  • Globalization of production, changing technology in ocean shipping sector, shifting bargaining power from port service provider to port users, changing distribution patterns of the containerization and new implementation for the environment and safety concerns introduced new ways of administration in port sector. In these days, port industries cannot survive alone. Port operation and management has to be proactive to cooperate and integrate with other port operators or other industries. In the 21st century, cooperation in maritime sector is more common than that in the past with several different reasons in a mixture of forms of cooperation. Cooperation among port authorities, port operators, shipping line, inland transport service providers and/or related organizations themselves becomes to exist to overcome the challenges and development of the global transport chain. This paper investigates the concept of port cooperation and the case analysis of the cooperation in the port industry.

  • A Numerical model is developed in order to predict cross-shore beach profile change. In this model it is assumed that sediment transport is generated by waves(bed load transport suspended load transport) and undertow which is defined as offshore directional steady flow in the surf zone. In addition wave tank experiments which reproduce storm-surge were performed. By comparing resulting profile of calculation with experiments, the applicability of this method is verified.

  • This study aims to propose an assessment tool of port service quality (PSQ) in the context of container transport logistics (CTLs), by taking the perspectives from port users. The CTLs defined in this study are the relevant activities of serving the physical flows of a container box from a point of origin via a container port to a point of destination. To address the ports' role in collaboration between its channel members in CTLs, the PSQ measures for all port user groups (i.e. common PSQ measures) are selected based on the relevant CTLs activities involved by port, and its users within terminal/port area as well as throughout the CTLs chain. An importance-performance analysis (IPA) is applied as a diagnostic tool to analyse the status quo of Busan Port in CTLs contexts, by comparing the importance and performance (IP ) scores against each individual CTLs criterion. The findings from the IPA reveal that port managers and policy makers at the Busan Port should concentrate on six PSQ measures (i.e. SR1, SR4, ITS1, VAS1, VAS4, ICI3) to enhance PSQ in CTLs. However, four measures (i.e. ITS2, ITS3, ITS4, VAS2) are identified as a possible overkill, indicating an area of inefficiency where a remedial action of the cost-cutting decision is necessary. On the other hand, the Busan port shows an outstanding performance on four measures such as SR2, SR3, ICI1 and ICI2. The measures are not only important but also high performance. The study findings provide managerial guidance to port managers in Busan Port, in view of searching for managerial and operational strategies for sustainable port growth.
