Recently, the efficient planning and operations of container terminals have become essential problems to develop the evaluation method with operational rules. Container terminals are required to have enough berths and container yards as well as various equipments and facilities, but in reality there are many differences in their resources owing to the circumstances of each terminal. This study introduces a simulation model for evaluating various operation rules for improving the performance of transshipment container terminal operations. This model can analysis various factors (throughputs, utilizations etc) and shows operational alternative considering design factors of transshipment container terminal with the related circumstances.

해운 항만 분야에서의 환적화물은 항만 물동량의 증가와 고부가가치 산업의 활성화를 통해 국가 및 지역 경제발전에 긍정적인 영향을 미치는 중요한 화물이다. 하지만 최근 중국의 경제성장 및 지속적인 항만 개발로 인해 중국으로 직기항하는 대형선박이 증가함에 따라 우리나라의 환적 물동량은 점차 감소할 것 이라는 예측결과가 제시되고 있다. 우리나라의 경우 항만 물동량 예측을 통해 항만 개발 계획이 수립되고 있으며, 일반적으로 환적화물이 전체화물의 40%를 차지할 것이라는 전제하에 개발을 추진하기 때문에 환적물동량 예측은 중요한 과제이다. 하지만 기존의 연구들은 항만 경쟁력의 변화를 고려하지 않고 과거 실적치를 통하여해 환적화물을 예측한 연구들이 대부분이다. 이러한 측면에서 본 연구에서는 SD기법을 통해 동태적인 관점에서 항만 경쟁력 지수 및 환적 물동량 변화치를 예측하는 것을 목적으로 하였다. 본 연구 수행 결과 2030년에는 한국의 경우 약 2천만TEU의 환적화물이 처리될 것으로 예측 되었으며, 중국의 경우 약9,000만TEU, 일본의 경우 약 250만TEU의 환적화물이 처리될 것으로 전망되었다. 즉 한국과 중국의 경우 연평균 4%, 6%의 성장세를 보여 환적화물 처리량은 지속적으로 증가할 것으로 예상되지만, 일본은 연평균 1%대의 증가세를 보여 일정수준으로 유지될 것으로 분석되었다. 본 연구의 결과는 컨테이너 항만의 환적화물 유치 및 경쟁력 확보를 위한 기초자료로 사용될 수 있다.

This paper estimated the container volumes for the Incheon port with univariate time series. As best suited models Winters' additive model, ARIMA model,and Winters' additive model were selected by import-export, coastal, and transshipment volume respectively, based on the data of monthly volume by October 2008 since January 2001. This study supposed the import-export container volumes would be decreased by 14% against that in 2008 and would have been recovered to the increasing trend of the volumes beyond the fourth quarter of 2010. The future import-export and transshipment volumes showed the increasing trend beyond 2011, while the coastal volumes would be on the stagnation. The yearly container volumes were finally forecasted as 1,705, 2,432, and 3,341 thousand TEU in 2011, 2015, and 2020 respectively.

The port throughput situation has changed since the 2008 financial crisis in the US. Therefore, we studied the situation, accurately estimating port traffic of Korean port after the 2008 financial crisis. We ensured the proper port facilities in response to changes in port traffic. In the results of regression analysis, Korean GDP and the real effective exchange rate of Korean Won were found to increase the container throughput in Korean and Busan port, as well as trade volume with China. Also, the real effective exchange rate of Korean Won was found to increase the port transshipment cargo volume. Based on the ARIMA models, we forecasted port throughput and port transshipment cargo volume for the next six years (72 months), from 2015 to 2020. As a result, port throughput of Korean and Busan ports was forecasted by increasing annual the average from about 3.5% to 3.9%, and transshipment cargo volume was forecasted by increasing the annual average about 4.5%.

Variability factors of transship cargo in the container transportation market analysis short term factors. In the past, studies on the factor of variability in container cargo volume have focused on long term volume forecast and increase in investment and competitiveness from strategic perspectives. Unlike previous studies, this paper analyzes factors of variability in transshipment volume rapidly varying in short term and seeks measures. Since it was identified that transshipment volume depends on vessel operation cost and port volume in long term but effectively on special strategies launched by port authorities in short term, the port authority experienced rapid drop in volume should continue to observe strategies of competition ports and to make use of strategies seeking appropriate countermeasures.

By the rapid expansion of containerization and intermodal transportation in international shipping since the 1970's, the larger containerships have emerged and concentrated their calls at a limited number of ports. Moreover, large-scale container terminals have been built to accommodate the ever-larger containerships, and the mordernization of terminal facilities and many developments in information technology etc. have been brought out. Thus, unlimited competition has been imposed on every terminal with neighbouring ports in Japan, Singapore, Hongkong and Taiwan etc. The purpose of this study is to suggest how the container terminal operators cope with unlimited competition between local or foreign terminals. The results are suggested as follows: First, transshipment cargoes, which the added value is high, is to be induced. Second, the function of storage is given on On-Dock Yard. Third, Berth Pool Operation System is to be introduced, especially in Gamman Container Terminal and Kwangyang Container Terminal. Fourth, the cargo handling charges is to be decided by terminal operator.

항만배후단지는 실질적인 신규 물동량 및 고부가가치 창출에 어려움을 겪고 있다. 항만에서 단순 경유되는 환적화물을 수탁가공으로 전환하여 항만배후단지로 유치할 수 있다면 신규 물동량과 고부가가치 창출에 크게 기여할 수 있을 것이다. 본 연구는 국내 수탁가공 실적과 환적화물의 적하목록 실적을 기준으로 항만배후단지 유치에 적합하고 수탁가공으로의 전환도 가능한 품목과 그 규모를 산정하였다. 수탁가공 실적 상위 50개 품목을 분류하고 그 중 33개 품목이 항만배후단지 유치에 적합한 것으로 제시하였다. 부산항은 국내 수탁가공 전체 규모보다 3.2배가 많은 유치 가능 물동량을 단순 환적하고 있는 것으로 나타났다. 광양항도 상당한 물동량이 단순 경유하는 것으로 나타났다. 본 연구는 환적화물의 적하목록을 무역실적과 비교한 첫 번째 연구로서 항만공사, 정부, 지자체 등의 기업유치 활동에 유용한 정보를 제공할 것이다.

본 연구는 철도물류터미널에서 작업선 배정 및 열차조성을 위한 최적화 모형을 제시한다. 본 연구에서는 하루 터미널 작업 종료시간을 최소화하며 처리 컨테이너수를 최대화하는 다기준 정수 계획 모형을 개발하였고, 의왕ICD로부터의 실제 데이터로부터 구성된 현실 문제에 대해 본 모형을 적용하여 실험하였다. 실험 결과 목적함수의 가중치에 따라 다양한 파레토 최적해를 산출할 수 있었으며, 기존의 해보다 전체 작업종료 시간을 약 6% 감소시켰으며 이러한 결과는 본 연구에서 개발한 최적화 모형을 적용할 경우 설비의 추가적인 확장 없이도, 철도 컨테이너 터미널의 처리효율 향상을 가져올 수 있음을 의미한다.

The Port of Busan is currently ranked as the seventh largest container port worldwide in terms of cargo throughput. However, port competition in the Far-East region is fierce. The growth rate of container throughput handled by the port of Busan has recently slowed down. In this study, we analyzed how economic conditions and multiple external shocks could influence cargo throughput and identified potential implications for port business. The aim of this study was to build a model to accurately forecast port throughput using the ARIMA model, which could incorporate external socio-economic shocks, and the VEC model considering causal variables having long-term effects on transshipment cargo. Findings of this study suggest that there are three main areas affecting container throughput in the port of Busan, namely the Russia-Ukraine war, the increased competition for transshipment cargo of Chinese ports, and the weaker growth rate of the Korean economy. Based on the forecast, in order for the Port of the Port of Busan to continue to grow as a logistics hub in Northeast-Asia, policy intervention is necessary to diversify the demand for transshipment cargo and maximize benefits of planned infrastructural investments.
