  • To analyze the port choice hierarchy, factorial and AHP analysis were conducted based on the survey for shippers using west coastal ports. As the result of analysis with 17 factors, 6 main factors; port service, port operation and geographical condition, connectivity to hinterland, port cost, accessibility and facilities were chosen. Based on this, AHP and correlation analysis of each factor were conducted. And the results were shown as cost, service, facility, connectivity, accessibility and operation in order. In addition, several ways for incentive program, the most important factor based on AHP analysis, to influence shippers around west coastal port were reviewed. As the result of review for the incentive program of domestic container ports, it was shown that three ports, Gun-san, Dae-san and Mok-po, offer incentive to shipper while two ports, Pyeong-tak and Dang-jin, do not. Therefore, the former three ports need to reinforce the existing incentive program while the latter ones introduce it.

  • The economic appraisal of a port remodeling project must be transparent and persuasive to the public over the entire stage of the project. A project evaluator need to be familiar with the guidelines on evaluation, and to do his best to follow the guidelines to evaluate the given project. To make the right decision on investment, the evaluator must take into consideration not only economic efficiency, but also equity issues such as income redistribution and balanced development between regions. Port remodeling projects tend to produce externalities to the environment. However, these externalities are of qualitative nature, and hard to measure in monetary terms, so these are liable to be ignored in the process of project evaluation. Two different approaches - RP(revealed preference) and SP(stated preference) have been tried to assess the value of these non-market goods. Government authorities need to set minimum guidelines which project evaluators must follow in order to make the evaluation more reliable.

  • This study aims to apply and examine the stochastic approach for empty container repositioning and leasing problem. For this a case study has been carried out on actual data such as various cost components and traffic flow. The results reveal that the proposed methodology produces more realistic results than the conventional deterministic approaches. It is also found that the results are significantly affected by the accuracy of demand and supply forecast.

  • 종래부터 CATV 또는 MATV시스템의 신호분기회로로 사용되어 오고 있는 Tap-off는 단지 실험적 경험적으로 제작되어 왔으며 이론적인 해석이나 엄밀한 설계법이 확립되어있지 않았기 때문에 그 성능에 있어서도 대역폭이 좁거나 분기 특성이 나쁜문제점등이 있었다 따라서 본 논문에서는 보조변성기가 부가된 변형된 약결합성 신호분기기를 제안하여 설계의 자유도를 높힘으로써 상당히 조밀한 결합간격의 회로구성이 가능한 설계법을 제안하고 그 주파수특성을 계산하여 제안한 변형된 신호분기기의 설계법의 유효함을 확인하였다.

  • This study estimated the economic value of port redevelopment projects. The port redevelopment project consists of a combination of goods between market goods and non-market goods. The value of market goods can be measured at prices in the real market, but it is difficult to convert value estimates for non-market goods into currency values. Therefore, in this study, economic benefits of port redevelopment projects were estimated by the using the CVM. The estimated model used the Hanemann's model and the Bayesian approach to estimate the WTP of the sample group's using the single boundary model. Estimating the household's WTP, the Hanemann's model was estimated at KRW 10,038.33 and the Bayesian approach at KRW 12,217.1. As of the five-year period(discount benefits), the economic benefits of the port redevelopment project were estimated at 920.7 billion won for the Hanemann's model and 1.12 trillion won for the Bayesian model on a national basis. Meanwhile, as a result of estimating economic benefits(discount benefits) based on the administrative districts of Busan·Gyeongnam·Ulsan regions(five-year period), the Hanemann's model was estimated at KRW 140.4 billion and the Bayesian approach was estimated at KRW 170.8 billion.

An Empirical Comparison and Verification Study on the Containerports Clustering Measurement Using K-Means and Hierarchical Clustering(Average Linkage Method Using Cross-Efficiency Metrics, and Ward Method) and Mixed Models (K-Means 군집모형과 계층적 군집(교차효율성 메트릭스에 의한 평균연결법, Ward법)모형 및 혼합모형을 이용한 컨테이너항만의 클러스터링 측정에 대한 실증적 비교 및 검증에 관한 연구)

  • The purpose of this paper is to measure the clustering change and analyze empirical results. Additionally, by using k-means, hierarchical, and mixed models on Asian container ports over the period 2006-2015, the study aims to form a cluster comprising Busan, Incheon, and Gwangyang ports. The models consider the number of cranes, depth, birth length, and total area as inputs and container twenty-foot equivalent units(TEU) as output. Following are the main empirical results. First, ranking order according to the increasing ratio during the 10 years analysis shows that the value for average linkage(AL), mixed ward, rule of thumb(RT)& elbow, ward, and mixed AL are 42.04% up, 35.01% up, 30.47%up, and 23.65% up, respectively. Second, according to the RT and elbow models, the three Korean ports can be clustered with Asian ports in the following manner: Busan Port(Hong Kong, Guangzhou, Qingdao, and Singapore), Incheon Port(Tokyo, Nagoya, Osaka, Manila, and Bangkok), and Gwangyang Port(Gungzhou, Ningbo, Qingdao, and Kasiung). Third, optimal clustering numbers are as follows: AL(6), Mixed Ward(5), RT&elbow(4), Ward(5), and Mixed AL(6). Fourth, empirical clustering results match with those of questionnaire-Busan Port(80%), Incheon Port(17%), and Gwangyang Port(50%). The policy implication is that related parties of Korean seaports should introduce port improvement plans like the benchmarking of clustered seaports.

  • 항만 배후단지는 항만과의 연계된 네트워크로 점점 중요해지는 가운데 다국적으로 앞 다투어 고부가 가치 창출을 위한 다양한 법과 제도를 마련하고 있다. 유럽, 아시아, 북미 등 여러 국가에서 배후단지 활성화를 위한 투자와 발전을 위해 노력하고 있으며 이에 한국도 제3차 항만배후단지개발 종합계획을 통해 단계적 변화의 움직임을 보여주고 있다. 따라서 본 논문에서는 DEA(Data envelopment analysis)와 Malmquist 분석을 통해 한국의 주요 항만배후단지의 생산성과 효율성을 파악하였다. 분석결과 부산 신항 북컨, 광양항 서측배후단지는 효율성이 높고 부산 신항 운동, 광양 동측 배후단지 및 아암 1단지는 효율성이 낮게 나타났다. 연구 분석을 통해 향후 항만 배후단지의 경영 환경 및 수익성이 개선되어야한다는 점을 시사한다.
