인천항은 동북아 경제권의 중심항만으로 경인공업지대 및 수도권지역에 각종 원자재를 공급하며 수도권 일대에서 필요로 하는 소비물자의 적기공급등 국가경제발전에 중추적 역할을 담당하고 있다. 또한 인천항은 대 중국화물, 장래 남북화물을 유치하는데 아주 유리한 여건에 있어 인천지역의 물동량은 해마다 더욱 증가할 것으로 예상된다. 하지만 인천항의 처리능력의 한계를 이미 넘어섰고 이로 인해 만성적인 체선 · 체화현상이 발생하고 있다. 이러한 항만시설의 부족은 항만시설의 신규건설을 통한 항만공급 능력의 확대가 장기적으로 바람직하나 현실적으로는 항만시설의 기능재배치를 통한 운영효율화로 시설능력을 증대해야 한다. 본 연구에서는 시뮬레이션을 이용하여 시설소요 화물량과 하역능력을 비교하여 하역능력이 절대적으로 낮은 화물과 하역능력이 높은 화물을 부두별로 재배치함으로써 시설능력의 증대를 도모하고자 한다. 특히 인천항의 기능재배치의 시뮬레이션을 위한 본 시스템은 화물의 이동이나 화물량의 변화, 선석의 배정규칙을 변경하여 여러 가지의 시나리오를 설정할 수 있고, 이에 대한 결과를 하역사, 화물군, 부두별로 분석하여 영향을 검토함으로써 항만운영계획에 대한 의사결정을 지원할 수 있을 것이다.

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.

So far, the port cargo handling capacity of general cargo was computed using simple formulae based on mathematical models. However, this simple calculation could not be able to reflect the reality. Thus, the simulation method was applied in this paper to overcome the limitation that the calculation method used in the past studies has. The process occurring from arrival to departure of a ship, which is reflecting the process rules of berth, was modeled to estimate the optimum level of handling capacity by using an example of the loading and unloading of an appropriated wharf at the harbor, and simulation was performed by developing the prototype. The actual processing capability of Mukho port was compared to the estimated capability calculated using the simulation method and the optimum level of capability could be computed by repeatedly simulating the input variable condition of the simulation prototype.

In the future, the global container handling market will be reorganized into larger ships and shipping alliances, and the bargaining power of shipping companies will be further strengthened. Therefore, the global terminal operator (GTO), which has a global network, vast experience, and operational know-how, is expected to strengthen its competitiveness. In Korea, the central government promoted the development of GTOs in the mid-2000s, but it failed, mainly due to disagreements between port stakeholders. In this study, the macroeconomic indicators that have the same effect in all regions were used to analyze GTO management performance. In the short term, it could be used to establish the business strategy of domestic terminal operators based on changes in macroeconomic indicators. In the long term, it would be used to establish a promotion strategy for GTOs in Korea. The results of analyzing the impact of macroeconomic indicators on the GTO's profit show that the GTO's profit is significantly affected by cargo handling capacity, the consumer price index of the United States, the Shanghai Composite Index, the Crude Oil Price, and the London Inter-bank Offered Rate (LIBOR). However, the scale of impact was not significantly different between public and private GTOs.

This paper investigate the problems of standard container port handling capacity in establishing national port development plan in Korea. Considering container port developing, it's not easy to adopt container port service quality parameters such as lay time constraint of very large container ships by using the standard guideline of container port handling capacity. A simple methodology that connects vessel waiting to service time(w/s) and berth occupancy to costs has been used to evaluate the performance of a container terminal. But the total handling capacity have to be calculated by the performance of the handling system and number of equipments and layout of terminal by using computer simulation that represents of reality events needs to be performed by probabilistic techniques. A simulation model of estimation of container terminal capacity is introduced in order to establish a hub terminal for very large container ships that focus the port's quality of service and also suggest as tool for policy maker to justify a required port investment.

In order to mitigate the overcapacity of Busan port, Busan new port has been developed as transshipment port which is capable of handling 8,000 TEU containership. Generally, design of transshipment port has to reflect the capacity of feeder because both mother vessels and feeders enter the planned port at the same time. However, the existing plan of Busan new port capacity needs to be reexamined since the adopted capacity of each berth at new port, 300,000 TEU, does not seem to be enough to handle both mother vessels and feeders. Therefore, in this study we calculated the required number of berth and berth length by considering cargo handling capacity in terms of the ship size and this study makes some implications in relation with the terminal development plan.

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.

세계경제의 성장과 더불어 꾸준히 증가하는 해상물동량을 원활히 처리하기 위하여 정부에서는 항만시설 확충사업과 기존시설의 개량사업을 지속적으로 추진하고 있으나 국가재정의 한계로 항만시설에 대한 투자가 미흡하여 만성적인 하역능력 부족현상이 해소되지 못하고 있는 실정이다.(중략)
