부산항 북항은 일제 강점기에 축조된 일반부두(1,2,중앙,3,4)에서 시작하여 자성대, 신선대, 감만 부두 등으로 확장되었다. 그러나 도심과 접합 항만의 입지적 특성으로 인하여 물류 활동 및 도시 활동 양 측면에서 문제가 대두되어 왔다. 장치장 부족으로 인한 부두밖 장치장(ODCY) 확대가 대표적이다. 이것은 물류비용 증가뿐만 아니라 우암로, 충장로 등 주요 간선 도로상의 화물 차량 비중을 높이는 결과를 가져와서 심각한 사회 문제가 되고 있다. 본 연구는 일반부두와 자성대부두 재개발로 인한 충장로, 우암로 등 인접 주요 간선도로의 통행량 감소 효과를 분석하고 그동안 차량 통행으로 발생된 교통혼잡으로 인한 사회적 비용의 절감효과를 분석하여 두 부두의 재개발로 인한 효과를 제시하는데 목적이 있다.

Since the middle of 1950's, containerization has been rapidly spread over the world in virtue of great merits providing to interensts, and the fundamental changes in port management and prot operations are resulted. As the container terminal is a complex system which is consisted of various subsystems, the treatment for improving the productivity is required in a comprehensive fashion, both in each of its parts and as an integrated system. This paper aims to make an intensive analysis of the Busan Container Terminal system, especially focusing on its subsystems such as ship operation system, storage system and transfer system. First of all, the intrinsic capacity of various subsystems is calculated and it is checked whether the current operation is being performed effectively through the formal analysis. Secondly, the suggestion is presented to improve the operation by considering the throughput that the port of Busan will have to accept in the near future. The results are as follows; 1) As the inefficiency is due to the imbalance between various subsystems at Busan terminal, transfer equipment level must be up to 31% for straddle carrier and 67% transfer crane above all. 2) The yard capacity must be increased by reducing the free dwell time of containers in order to accept the traffic volume smoothly in the near future. 3) The better way to reduce the port congestion is to change berthing rule from the FIFP to the Pre-allocated system by considering the ship arrival pattern.

컨테이너 터미널에서느 매일 24시간, 365일 운영하는 데에 있어서 다양한 의사결정을 필요로 하며, 이 모든 의사결정들은 상호 관계를 가지게 된다. 이러한 의사결정의 궁극적인 목표는 선박 작업시간, 작업 처리를 위해 사용되는 자원들, 터미널 내부 도로의 혼잡도 등을 최소화하는 것이다. 또한 필요한 저장 공간을 효율적으로 이용하는 것이다. 따라서 컨테이너 터미널의 운용 효율을 더 한층 강화하기 위해서는 이러한 의사결정의 범위와 복잡성이 더해지게 되어 의사결정 도구의 필요성이 강조될 수 밖에 없다. 이 논문은 이러한 목적을 위해 의사결정시스템을 위한 평가요소들을 도출하고, 의사결정시스템 설계에 가장 큰 영향을 주는 평가요소, 즉 야드장치장 배경, RTGC 배정, QC당 YT 배정의 최적화 전략을 제안한다. 그리고 G2 언어를 상요한 시뮬레이션에 의해 의사결정시스템 설계의 효율성을 선박작업시간 비교를 통하여 평가한다.

Rapid change in the technological environment of marine transportation and the development of the ocean shipping industry have fostered a revolution in the port system. This in turn has caused major changes in the function and use of port in Korea. Aside from this. Mokpo Port, however continues to decline, because the existing port facilities and related subsystem are already obsolete with no chance of regaining operational effectiveness and treatment for proper implementation. Although a few studies have been done on the Mokpo Port, has not been found, any reseach for the analytical approach to the transportation system of it. This paper aims to make an extensive analysis of the physical distribution system in Mokpo Port focusing on the coordination of subsystems such as navigational aids system, quay handling and transfer system, storage system and inland transport system. The base of introduced simulation tool here is the queueing theory. The overall findings are as follows; 1. Among those vessels called at Mokpo Port in 1994, the average size of oceangoing vessels is 4,922.1 G/T, and the domestic is 317.8 G/T. The average arrival interval and service time of the domestic vessels are 6.0 hours and 24.1 hours respectively marking the berth occupation rate over 100%. Those for oceangoing vessels are 34.5 hours, 120.0 hours and 37.2%. In order to maintainin the berth occupation rate to 70% the capacity considering the 1994 of domestic piers must be extended to 145% and oceangoing vessels must be increased to 165% year called. 2. The capacity of approaching channel is enough to handle the total traffic volume. 3. Tugs are sufficiently being provided to handle all ships requiring their services 4. The capacity of storage and inland transportation systems are sufficient to handle the throughput and the yard stroage utilization rate of No.1 $\cdots$ No.5 is 4.5% and No.6 1S 30% of 1993's. 5. The utilization rate of LLc(Level Looping Crane) and PNT(PNeumaTic) are 2.7% and 18.8%, respectively. Practical solution and proposal for improvement of Transportation System in Mokpo Port are as follows; 1. To avoid the congestion in domestic pier introduction of a new port operation system is necessary allowing the domestic vessel to use the oceangoing pier. 2. To establish the port management information system to improve the efficiency of port operation. 3. To build a new storage system for high valued cargos including modernization of the present storage and handling system. 4. To insure the safety of navigation in approaching channel, The Vessel Traffic System including separation scheme is introduced. 5. To interest enormously on public relation to ship owner's association, shippers and consignees by showing that they can save cost and ship turnaround time in order to promote the call to Mokpo Port. At last, to be strategically change the function of Mokpo Port to the Leisure, Fishing & Ferry as well as Maritime port.
