본 연구에서는 컨테이너 터미널의 적정 안벽능력(Quay Capacity)을 분석하기 위한 시뮬레이션 모델을 구축하였다. 모델에서는 선박의 터미널 도착 특성, 선박별 양하량 및 적하량, 컨테이너 크레인(Container Crane, C/C) 생산성 및 투입대수 등을 입력변수로 입력하였으며, 시뮬레이션 결과로써는 안벽점유율, 선석 점유율, 대기시간 비율, 대기비율, Norm time 초과비율 등을 출력하였다. 이중 컨테이너 터미널의 평가지표로는 Norm time 초과비율, 대기비율 및 안벽점유율을 적용하였다. 컨테이너 터미널을 운영중인 터미널의 터미널 운영실적 자료를 이용하여 모델의 확인 및 검증을 실하였다. 모델은 Knowledge Base에 근거하여 수행되는 G2를 이용하여 구축하였다.

This study aims at calculating berth length required of the given volume of containers. For this, unlike previous studies assuming 300,000 TEU per berth as the capacity of a berth, this study attempts to apply more realistic situation such as the distribution of vessel size, lifts per vessel, berth time by vessel size, and average berth occupancy ratio. the result are compared with that of Pusan New port planning.

The scale of ship's cargo transport is getting larger, more economics of scale are gained the speed is higher and the size of quay fundling equipment in container terminal is larger. The productivity cf the quay qffects occupation for limited scale of yard. This paper aims to calculate the yard occupation by handling systems, such as OHBC, RMGC, RTTC, etc, and lay-out.

This study aims to analyse the coefficient used to estimate the quay capacity per year at the container terminal. The capacity of the container terminal is composed of the capacity at the quay side and the other working conditions at the back of the quay side. But when we refer the capacity of the container terminal, generally we used capacity as that of the container terminal. To estimate the quay capacity independently of the working conditions at the back of quay side, we calculate the quay capacity as th product of working hours per year, productivity of container crane and relate other coefficients, such that berth utilization, crane utilization and efficiency. So that coefficients are properly defined to reflect the other working conditions. If we calculate the quay capacity by the product of working hours modified by the berth utilization and crane productivity modified by the crane utilization and efficiency, the meaning of that coefficients must be strictly defined. So there could be no confusion to apply that coefficients to calculate the quay capacity. In this study, we exclusively define the meaning of the berth utilization, crane utilization and efficiency according to the internal-meaning of thats in the function to calculate the quay capacity. And compare each coefficients by decomposing the working hours at the terminal.

With advancements of quay side handling equipment and technologies, congestion in terminal operation has moved to the storage yard side from the quay side. The importance of storage yard management has increased in overall terminal operation. Thus, many studies have been conducted to optimize the storage yard management of container terminals. However, there is no academic work to estimate the change of storage yard occupancy ratio by itself in the future. This paper examines the probability of storage yard occupancy ratio in the container terminal of Busan New port using the Markov chain analysis which explains probability change with passing time. The result shows that it is most likely to have the probability of maintaining a high level of storage yard occupancy ratio in the container terminal of Busan New Port.

A problem of handling capacity calculation of berth is very important factor for decision about a port development scale like as the number of berth, size of back storage yard. If handling capacity per berth calculated low, the number of berth is increasing and the size of yard decided for propriety level of handling capacity. The propose of this paper is re-calculate of handling capacity for Busan container port by firstly government plan and actual result of Busan port like as waiting rate, berth share and handling capacity, and then realistic number of crane and berth share to be applied.

Most q the domestic container terminals are inferior to throughput q container. The reason why they have the difference between the handling capacity q planed quay and its real. By putting into quay handling equipment, the productivity of quay can be improved, waiting rate q the ship can be lowed. This paper suggests more resonable terminal construction, throughout comparing with previous construction way, improved handling capacity and the economical efficiency of equipment costs, labor costs, construction costs, operation costs on change of terminal size by adding the equipment.
