  • In this paper we presents an approach to assessing the efficiency of freight railroad stations reflecting freight item importance weights with multiple performance indicators and multiple operational condition indicators. We evaluate 187 freight railroad stations using data envelopment analysis with assurance region. Each freight item's loading/unloading volume is used as a performance indicator. Freight labor and yard capacity are used as operational condition indicators. Freight item importance weights are reflected to the data envelopment analysis as assurance region. The evaluation results facilitates the organization's decision making by providing valuable information.

  • The modal spilt for road has been increased, but, for railroad it has been decreased from 17.2%(1990) to 6.3%(2006). It is important to study on improving competition for railroad transportation so that freight transport industry for railroad which is getting to decrease in Korea will be increased. The objective of this study is to analyze the competitiveness of railroad transport compared with road by providing a high-speed railway. The indicators representing the competitiveness of railroad transport are determined. The main influenced factors for mode choice include transport cost, transport time, level of service. Precisely, three commodities type, container, cement, steel, are analyzed.

  • This study is an attempt to grasp the spatial patterns and characteristics in the freight flows based on freight quantity data in 1997. The spatial background for the study is the Capital Region, which plays an important role in regional economics and industrial development. The methodology in the research used factor analysis to produce a functional region. The study selected three categories of freight that account for more than 60 percent of freight flows, chemical industrial goods, light industrial goods, and metal machinery industrial goods. The target analysis unit is divided into 36 zones. The common characteristic of the three categories is that they are concentrated at one specific region than are dispersed regionally. And in particular, the remarkable feature is that the central region of the study is Seoul. Usually the eminent regions of nows were made where environment of distribution facilities is good but these were made in a less than good environment. I think a reason is that facilities were uneven distribution.

  • The study developed physical distribution channel choice models reflecting decision making of the firms and studied how choice decision factors influence selection of distribution channel. The distribution channel survey data in Korea was used to do empirical study. As a choice set, distribution channels were classified into two main choice channels: direct and indirect channels. In addition, indirect channels were classified into other three channels according to the type of intermediate point: distribution center, wholesale store, and agency. This study developed choice models by applying both binary and multinomial logit model with various set of factors. The results showed that the developed logit models seemingly reflect distribution channel choice behaviors. The hypothesis tests on how each factor influences choice of distribution channel were performed and discussed as well.

  • 물류활동에서 운송부분이 차지하는 중요성은 기업의 경영자층에게 더욱 중요하게 인식되고 있는데, 이는 경쟁 환경 때문이다. 경쟁환경에서는 'Output Logistic' 즉, 운송활동의 수행정도에 따라 물류활동의 성패가 결정된다. 따라서 기업물류활동의 근간인 운송활동의 주요 결정요인과 선택형태를 알아보고, 이들이 실제로 기업의 물류활동에 어느 정도 영향을 미치는지를 심층적으로 분석해보는 것도 매우 의미 있는 일이라 하겠다. 더구나 우리 나라의 현재의 경제여건에서는 물류비에 대한 효율화 작업이 필요한데 반해 그 동안의 연구들을 살펴보면 SP 자료를 이용한 가상적 상황하에서의 화주의 선택행태를 분석하였으므로 실제 선택한 수단간의 gap을 극복할 수 없었다. 기업은 운송수단의 선택시 복잡한 결정과정을 갖는다. 이는 운송부문이 총물류비용에서 차지하는 중요도 때문이다. 기업의 운송관리자는 화물을 출하할 때마다 선택의 기로에 서게 된다. 즉, 일부는 조직 체계나 다른 계약 여건에 따라 이전과 동일한 수단을 선택하는 경우도 있지만, 많은 경우에는 매번 출하시 마다 최적의 운송수단을 선택하기 위한 새로운 결정을 하게 된다. 본 연구는 이러한 화주의 수단선택행태를 실제 RP 자료를 이용하여 분석하였다. 수단선택모형의 적용 및 분서결과를 살펴보면 상당히 attractive한 결과를 발견할 수 있는데 각 품목별 추정 값이 운송거리에 대해서는 음으로 운송비용에 대해서는 양으로 나타나고 있다. 다시 말하면 운송거리가 길수록 효용은 감소하고 운송비용이 커질수록 효용은 증가한다는 것을 의미하므로 그 분석결과가 올바른 결과를 도출하고 있지는 않다. 그러나 여기서 알수 있는 것은 운송거리와 운송비용이 각각 주요한 변수라는 것이다. 모형의 타당성을 검증하기 위해서는 logilikelihood 값을 구하여 $\rho$^2분석을 시행하였다. 여기서는 각 품목별로 $\rho$^2값이 약 0.15~0.3의 비교적 높은 수치를 보여주고 있으므로 모형의 설명력이 어느 정도 있다는 것이 아울러 증명이 되었다. 상관관계에 대한 분석에서는 영업용 차량간의 상관관계가 높게 나타났으며, 이는 곧 영업용 화물차량을 적재중량별로 구분하는 것이 별 의미가 없음을 의미한다. 다시 말하면 자가용 차량을 보유하고 있지 않은 회사는 다른 운송전문업체에 화물운송을 의뢰하게 되므로 출하중량에 따라 화물차량을 구분하는 것에 대해서 그다지 큰 고려를 하지 않는 것으로 해석할 수가 있다.

  • Busan port's main function is handling container cargo compared to world major ports and the percentage of handling general cargo such as dirty bulk cargo is very low. In other words, although total cargo weight of Busan port that recorded the handling result of 13.29million TEU in 2008 reached 113.05million ton, total cargo weight of general cargo was 15.31million ton, so container cargo accounted for 88.1% of whole cargo weight. However, it is the time to create high added value by the increase of handling and marketing dirty bulk cargo. Originally, the dirty bulk cargo was not the avoided object from the first. Somehow, it is a very high added value cargo, and is surely essential strategic material to basic industries of nation. However, it becomes dirty bulk cargo as the companies are reluctant to handle it because of environmental problem, distinct characteristic in handling, uncertain break even point due to imbalance between supply and demand compared to container cargo. However, items that are classified as dirty bulk cargo now are certainly necessary strategic materials to national basic industries or national life. Besides it seems to be a high added value cargo here and now. Therefore, it is time that increasing of handling dirty bulk cargo by marketing it and the system for efficient handling such as constructing the exclusive use wharf in Busan port, modernizing of facilities and equipments, stable secure of place for holding and handling through development of distribution complex by item, efficient data processing and closer cooperation by setting up a SCM of related authorities are needful.

  • The aim of this study is to select the import and export goods which contribute to activate the operation of port hinterland. The spatial ranges of this study are A-am 1 logistics complex and 4dock hinterland. The Factor Analysis(FA) and Analytic Hierarchy Process(AHP) are used as the methodologies. Eleven low evaluation factors including 'creation of traffic cargo volume' are selected by precedent studies and four high evaluation factors including 'effective management' are grouped through factor analysis. As the result of priority among low evaluation factors through AHP, 'creation of traffic cargo volume' is the most important factor. Moreover using the AHP, 'electronic component' is the most important item which activate the Port of Incheon and its hinterland. So cargos which have the potential to create traffic cargo volume such as 'electronic component' must be managed strategically and this study can be used as important index when people concerned attract items.

  • Due to the economic growth of China and the geographic advantage that Gunsan and Janghang ports are close to China, recently traffic of China is rapidly increasing and the role of Gunsan & Janghang ports as a gateway port of west coast became more important. There, however, remains that Gunsan and Janghang port still don't equip with enough facilities and strategies to handle increasing traffic. The purpose of this paper is to analyze O/D data of Gunsan.Janghang Port and present the result of O/D as preliminary data. O/D data of Gunsan and Janghang had been analyzed by kinds of general cargoes and from/to China's ports and this paper suggests to the competitive strategies of Gunsan and Janghang port to attract cargoes from/to China particularly.

  • This paper analyzes the specific product-basis trade structure between Busan and Japan using the recent 2000-2007 trade statistical data. Several specific product-basis trade structure tests such as intra-industry trade index and market comparative advantage index show that there are considerable differences in intra-industry trade structure between Busan and Japan. Furthermore, this paper found that Busan has high quality vertical intra-industry trade and horizontal intra-industry trade as well as low quality vertical intra-industry trade in trading with Japan. While Busan has the market comparative disadvantage in automobile-part products in Japan. This paper also examines the contribution to trade balance of Busan's exports and the movement of Busan's comparative advantage patterns in Japan. The comparative advantage appears to have overall stability and convergence properties using symmetric indices.

  • Busan port has played a part as the main trade gateway in Korea for several decades. However, due to the rapid integration of China into the global economy and the grand changes in global trade structures, the trade gateway system in Korea and the status of Busan port have been transformed. Busan port's role as a trade gateway toward Japan and U.S. has increased during last two decades but, in cases of China, its importance has relatively decreased. Moreover, Busan port's competitiveness has been undermined in the most part of commodity trade. These phenomena reflect the high competition among trade ports which tend to increase the effectiveness of supply chains. Based on the geographical research tradition which has understood a port as a nexus between hinterland and foreland, this study focuses the changes in characteristics of trade freights and the status as a gateway of Busan port. This approach will contribute to the understandings of dynamics in the comtemporary international logistics.
