현재 국내에서는 물류시설의 부족, 물류시설의 비효율적 운영, 복잡한 유통구조, 물류산업의 낙후, 폐쇄적 정보 이용 등으로 인하여 필요 이상의 물류비용이 발생하고 있다. 이런 문제들을 해결하기 위해서는 물류구조의 전반적인 개선 및 물류시설의 확충 등이 필요하다. 하지만, 이러한 노력들이 기존의 원단위식 규모예측으로 이루어진다면 차량의 하역특성을 세밀히 고려하지 못하게 되고, 또한 향후 하역작업의 기계화 및 자동화 등으로 인한 작업능률의 향상을 반영하지 못 할 우려가 있다. 따라서 본 연구는 화물터미널에서의 화물차량의 이용현황을 기초로 대기행렬이론(queueing theory)을 적용함으로써 화물차량의 하역특성이 고려된 화물터미널의 최적규모산정법을 제시하였다. 또한, 현재의 하역시스템에서 이루어지는 작업들이 기계화 및 자동화, 정보화되었을 경우에는 화물터미널의 최적규모에 어떠한 영향을 미치는가에 대해 분석하였다. 분석결과, 하역시간의 규칙성 증가가 화물터미널의 규모변화에 미치는 영향은 크지 않은 것으로 나타났으며, 하역속도 및 서비스율의 향상은 화물터미널의 규모변화에 매우 큰 영향을 미치는 것으로 나타났다.

This work aims to : establish a model of the container physical distribution system of Pusan port comprising 4 sub-systems of a navigational system, on-dock cargo handling/transfer/storage system, off-dock CY system and an in-land transport system : examine the system regarding the cargo handling capability of the port and analyse the cost of the physical distribution system. The overall findings are as follows : Firstly in the navigational system, average tonnage of the ships visiting the Busan container terminal was 33,055 GRT in 1990. The distribution of the arrival intervals of the ships' arriving at BCTOC was exponential distribution of $Y=e^{-x/5.52}$ with 95% confidence, whereas that of the ships service time was Erlangian distribution(K=4) with 95% confidence, Ships' arrival and service pattern at the terminal, therefore, was Poisson Input Erlangian Service, and ships' average waiting times was 28.55 hours In this case 8berths were required for the arriving ships to wait less than one hour. Secondly an annual container through put that can be handled by the 9cranes at the terminal was found to be 683,000 TEU in case ships waiting time is one hour and 806,000 TEU in case ships waiting is 2 hours in-port transfer capability was 913,000 TEU when berth occupancy rate(9) was 0.5. This means that there was heavy congestion in the port when considering the fact that a total amount of 1,300,000 TEU was handled in the terminal in 1990. Thirdly when the cost of port congestion was not considered optimum cargo volume to be handled by a ship at a time was 235.7 VAN. When the ships' waiting time was set at 1 hour, optimum annual cargo handling capacity at the terminal was calculated to be 386,070 VAN(609,990 TEU), whereas when the ships' waiting time was set at 2 hours, it was calculated to be 467,738 VAN(739,027 TEU). Fourthly, when the cost of port congestion was considered optimum cargo volume to be handled by a ship at a time was 314.5 VAN. When the ships' waiting time was set at I hour optimum annual cargo handling capacity at the terminal was calculated to be 388.416(613.697 TEU), whereas when the ships' waiting time was set 2 hours, it was calculated to be 462,381 VAN(730,562 TEU).

치열한 항만간의 경쟁에서 우위를 확보하고 항만의 주요고객인 화주와 선사들의 요구사항을 만족시키기 위해서는 물류서비스를 개선해야한다. 하지만 물류서비스 불만의 대부분은 터미널 내부의 문제이기 보다는 화주의 잦은 운송변경 및 선사로부터 제공되는 하역정보나 운송사로부터 반입되는 화물정보의 부정확성에 기인하고 있다. 따라서 본 연구에서는 이러한 문제들을 해결하기 위해 장치장의 업무흐름을 프로세스 중심으로 재설계하고 장치장관리 프로토타입 시스템을 구현하였다. 또한 장치 할당 계획 수립에 선복예약목록 정보가 불충분한 화물정보를 보완하여 장치장 관리에서 협업적 공급망을 구성하는데 이용될 수 있음을 확인 하였다.

The purpose of this research is to suggest the activation plan of Busan port. In the past years, Busan port enjoyed the golden days because of the China's rapid economic growth. But China's continuous development of ports, the trend of increasing container ship size and increasing direct call to China are coming threats to Busan port. So Korea needs to revise the 'Northeast Logistics Hub' strategy because it is considered that Korea ports continuously will handle China's transshipment cargoes. But now China's transshipment cargo share has decreased by direct call to China ports. It means that China has a lot of its local cargoes, so many ship companies change liner service route to handle China cargoes except Bussan ports although Busan port is included in the main trunk route. In the future, Bussan port will not be able to compete again about throughput with China ports if Busan port's transshipment cargo share decreases. So we must find out and develop Busan port's strength which is the competitive edge. By good luck, Busan port has a few opportunities such as the developed feeder network service and geographical advantages. Busan port has many feeder network service like spider's web in any northeast countries so we can suggest that if Japanese shippers use Busan port to distribute their cargoes to Japanese local areas, its transport costs are cheaper than when they use Japan's main ports. In this paper analyzed side of cost when they use Bussan port like hub to distribute their cargo to their local areas. Because most companies tried to reduce the total cost about logistics. Finally, this paper suggests when northeast shippers(China, Japan) use Bussan port which is more economical than their local main ports.

The objective of this paper is to analyze the competitiveness of the Cargo Management improvement of FTZ(Free Trade Zone) in East Asia and to suggest several measures to improve it. To the end, various comparisons are made between the FTZ of Incehon and those in Hongkong, Taiwan, Shanghai. Competitive advantages of Incheon's FTZ over others lie in its better contiguity, frequency, quality service, and convenient connections associated with the airport. To be viable, however, the Incheon's FTZ needs to have strong supports from the central government such as more SOC investment, early introduction of RFID/UBIQUITOUS, improvement of customs process and logistics system, and competitive incentives to bring in more international channel hubs to this area. With these implemented promptly as suggested, the Incheon's FTZ will draw its competitive advantages over those in Taiwan and Shanghai and will play an vital role to bring in more MNEs to Korea.

In this study, design parameters of ice-transiting vessels in the world, currently in service or under construction, were collected and a database of principal particulars for each ship was established. To understand the recent design trend, ice-transiting vessels were categorized into four groups, i.e., conventional icebreakers, icebreaking tug/supply/research vessels, ice-strengthened passenger/car ferry and ice-strengthened cargo vessels. Changes in principal particulars for each group were reviewed and summarized. It was found that the most significant change in the design of ice-transiting vessels was the increment of large size commercial cargo vessels. It is believed that the recent hike of oil prices and booming of Russian economy has resulted in the need for year-round operation with bigger ships in the Baltic Sea and in the Sea of Okhotsk and also along the Northern Sea Route in Russian Arctic Sea.
