This study will examine the consolidation that is occurring in the shipping industry and its effects on Busan's status as a key transshipment hub in Southeast Asia as well as what measures the port must implement to attract transshipment traffic. With this in mind heading forward, trends in transshipment cargo, problems facing the port, as well as the current status of transshipment volumes at the Port of Busan must be fully understood so that thorough research can be done into appropriate measures to stimulate growth and attract cargo traffic. In this study, We analyze the current problems and status of transshipment cargo at Busan Port and factors affecting the competitiveness of transshipment cargo at Busan New Port, Korea's key import/export gateway, have been examined. We show the Strategies to Attract Transshipment Cargo at the Busan New Port which is to become a an optimal transshipment port, a port's internal environment including the scale and location of its hinterland, facilities and tariffs as well as the external environment including global networks and logistics IT management must be carefully considered as they are all key actors affecting cargo volumes.

Recently, the increasing trend for the transshipment traffic of Busan port in Korea is slowing down because of the extensive development plan of domestic ports in china. For solving this problem, Korea is going on the project for preoccupying the transshipment port for attraction of port traffic from the newly potential markets(NPM) based on the Northeast Asia area. As a part of the project, this paper proposes the efficient methodology for selecting the optimal shipping network and strategic transshipment port within NPM using the mathematical models and simulation analysis. For that, we firstly find the alternative transshipment ports within NPM through the status analysis of the current port traffic and shipping network and then, we choose the candidate transshipment-ports in order of minimizing the transport costs through the mathematical approach. With the scenarios based on the selected transshipment-ports, we perform the simulation analysis for choosing the optimal transshipment-ports and the shipping network minimizing the total costs and times concurrently. We expect that the results of this paper will be used efficiently when korea select the strategic transshipment-port in the future.

This research proposes the lateral transshipment policy that can deal efficiently with stockout in the two-echelon distribution network in supply chain. The lateral transshipment policy can be expected for retailers to response the change of customers' demands efficiently. Because of various factors, such as demand fluctuation, replenishment quantity, lead time, and so on, it is very difficult to decide optimal lateral transshipment time and quantity. We suggest the new lateral transshipment policy based on the service level in this research. The efficiency of this policy is proved by simulation experiments.

In multi-location inventory systems, lost sales due to stockout decreases not only retailers' profit but also whole supply chain's profit. Transshipment between retailers has been considered to be a major solution to the stockout problem, and many supply chains implement transshipment coalition among retailers. However, in practical situations, retailers occasionally refuses to accept the transshipment requests, mainly because they concern the future stockout possibilities of their own. Thus, the objective of this research is to analyze the effect of retailers' interaction under the transshipment coalition environment based on the simulations, and to provide effective policies to promote retailers' transshipment cooperation. Policies using penalty and incentive scheme are proposed, and it is shown that using proposed policies both the retailers' and the headquarter's profit can be increased.

There is the uncertainty of demands at each retailer in the supply chain. To satisfy customers' demand, retailer must have enough inventory. Nevertheless, stockout is occurred for some retailers. A lateral transshipment policy can be effectively used to deal with stockout. The new lateral transshipment policy, referred to service level adjustment (SLA), is suggested. The difference between SLA and previous policies is the integration of an emergency lateral 'transshipment with a preventive lateral transshipment to efficiently respond customers' demand in the proposed policy. Additionally, the service level to decide the quantity of products is considered. Simulation experiment is executed to treat stochastic factors in the two-echelon supply chain. The proposed policy can reduce total cost and is more effective to the change of demand, penalty cost, and ordering cost than the currently used policies.

Major ports in Northeastern Asia engage in fierce competition to attract transshipment traffic volume. Existing time series analyses for analyzing port competition relationships examine the types of competition and relations through the signs of coefficients in cointegration equations using the transshipment traffic volume results. However, there are cases for which analyzing competing relationships is not possible based on the results of the transshipment traffic volume data differences and limitations in the forecasting of traffic volume. Accordingly, we used the Lotka-Volterra (L-V) model,also known as the ecosystem competitive relation model, to analyze port competition relations for the long-term forecast of South Korean transshipment traffic volume.

Recently, there has been an increase in interest from the aspects of transshipment and connection between the means of transportation. Not only for passengers but also for freight transportation as the need for transportation efficiency is growing while the importance of logistic railway transportation is emerging. The domestic freight transportation is carried out by roads, railroads, ships, and port. However, as other means of transportation, except road, is impossible for Door to Door Service, multimodal transportation accompanied by road transportation is carried out. Here, even though 'transshipment' occurs, because of the lack of basic data regarding this, it is difficult to reflect it in the demand forecasting. With respect to the Korean freight O-D, it was very difficult to have equivalent comparison on the competitiveness and availability of transportation services between the point of departure and the final destination. Taking into account the study of implementation of logit model considering the time and cost of transshipment of multimodal transportation and the transshipment resistance value upon selecting means of freight transportation on multimodal transportation was comparatively insufficient. This study consisted of questionnaire targeting shippers, and based on this, transshipment resistance value was calculated by deriving utility function. By doing so, I intend to examine the effect 'transshipment' has on selecting the means of transportation occurring from freight transportation.

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.

각국은 자국의 항만을 Hub-port로 육성하고 환적화물 유치를 위한 전략을 실시하고 있으며, 부산항 역시 동북아 컨테이너 Hub-port를 지향하고 있으나 최근 환적화물이 점차 감소하는 추세에 있다. 따라서 본 논문은 항만의 환적량에 영향을 미치는 요인을 고찰하여 부산항의 환적량을 결정하는 요인을 분석하려고 한다. 기존의 연구의 경우는 환적량의 결정요인을 항만 인프라, 해상환적비용, 항만비용 및 항만서비스로 제시하여 전문가의 설문조사에 의한 연구가 대다수이었으나, 본 논문에서는 부산항의 환적량을 종속변수로, 주변국내외 항만의 컨터이너 물동량 및 환적량, 그리고 각국의 무역액과 경제성장률을 설명변수로 설정하여 연도별 데이터를 이용하여 분석하였다. 그 결과 부산항의 환적량은 상하이항과 도쿄항의 컨테이너 물동량이 증가할 때 그리고 중국과 일본의 무역액이 증가할 때 증가하는 것으로 나타났다. 결국 기존의 연구에서 제시한 항만의 환적량 결정요인들을 합리적으로 구비, 관리함과 동시에 상하이항이나 도쿄항의 관련 화물 유치에 최선을 다해야 할 것이다.

A strategic decision making on location selection for product transportation includes many tangible and untangible factors. To choose the best locations is a difficult job in the sense that objectives usually conflict with each other. In this paper, we consider a multi stage multi criteria transshipment problem with different types of items to be transported from the sources to the destination points. For the optimization of the problem, a goal programming formulation will be presented in which the location selection for each product type will be determined under the multi objective criteria. In the study, we generalize the transshipment model with a variety of product types and finite number of different intermediate nodes between origins and destinations. For the selection of the criteria we selected the costs(fixed cost and transportation cost), location numbers, and unsatisfied demand for each type of products in multi stage transportation, which are the main goals in transshipment modelling problems. The related conditions are also modelled through linear formats.
