Railroad is considered a representative echo-friendly mode, but there are many civil complaints due to dusts arising in the process of bulk cargo transportation. The freight station which is handling coal are slowly decreasing because of civil complaints. Generally gondolas and hopper cars kinds of freight cars have a role to carry coal such as anthracite and bituminous coal. The railroad competitiveness in the field of bulk cargo transportation is diminishing because there are cost increase and dust emission in the process of transshipment. In this study, we analysed the logistics process of bulk cargo transportation in the point of railroad and we could draw the problems from the logistics process. The results could be used to study various alternatives to improve the process of coal transportation.

부산항은 컨테이너 물동량 기준으로 세계 6위의 항만이며, 환적화물 기준으로 세계 2위의 항만으로 큰 기능을 하고 있다. 그러나 항만시설 및 운송업체에 대한 정책적 배려 부족으로 부산 신항내 환적화물의 운송과 배후물류단지 화물운송에 있어 과적단속이 심각한 문제로 대두되고 있다. 이에 관련 운전자, 운송업체, 항만 배후물류단지 담당자를 대상으로 그 실태를 살펴보고, 그 문제점을 파악한 후 개선방안을 제언하였다.

본 논문에서는 운송시간과 운송비용으로 구성되는 희생량 모델과 각 운송경로별 CO₂배출량을 고려한 수출입 컨테이너화물의 운송경로 선택에 관하여 고찰한다. 먼저 부산항을 이용하는 수출입 컨테이너화물의 물동량과 운송경로별 분담, 국내외 CO₂배출량 현황, 희생량 모델, 수출입 컨테이너화물의 시간가치에 대하여 간단히 살펴본다. 그리고 서울에서 발생한 수출입 컨테이너화물을 부산항으로 운송하는 경우를 가정하고 희생량 모델을 이용하여 계산한 각 운송경로별 희생량에 기초한 운송경로의 선택에 대하여 고찰한다. 또한 화물의 운송에 의하여 발생하는 CO₂배출량을 고려하여 결정한 환경부하 희생량을 추가한 희생량 모델을 이용한 운송경로의 선택에 대해서도 고찰한다. 본 연구의 결과, 희생량 모델에 기초한 컨테이너화물의 운송경로 선택이 수출입 컨테이너화물의 국내 수송 현황을 잘 나타내고 있는 것을 확인하였다. 또한 연안운송의 운송분담율을 높이기 위해서는 운송시간의 단축이 가장 효과적인 것을 확인하였다.

냉동컨테이너 화물의 해상운송이 증가함에 따라 냉동컨테이너 화물의 손상과 관련된 분쟁 및 클레임이 화물 소유자인 화주와 화물운송의 주체인 운송인 간에 빈번하게 발생하고 있는 실정이다. 냉장 냉동화물은 그 특성상 다른 일반화물에 비해 화물손상에 대한 분쟁 및 클레임이 많은 편이며, 일단 화물손상이 발생하면 관련 당사자들에게 분쟁이나 클레임으로 인한 불필요한 시간낭비 및 물류비용 즉, 손상화물의 검사비용, 손상화물의 폐기비용, 클레임관련 소송비용 등 불필요한 경제적 비용을 증가시킨다. 따라서 본 연구의 목적은 냉동컨테이너 화물손상의 개선방안을 모색하여 해상으로 운송되고 있는 냉동컨테이너 화물의 손상을 사전에 예방해 화물손상으로 인한 불필요한 물류비용 및 시간낭비를 감소시킴과 동시에 냉동컨테이너 화물을 목적지까지 보다 안전하고 효율적으로 운송하여 원활한 물류흐름에 기여하는데 있다.

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%.

A scheduled airlift is the most critical part of the air transportation operations in ROK Air Force. The military cargo-plane routing problem is a PDPLS (pickup and delivery problem in which load splits and node revisits are allowed). The cargo which is transported by a military cargo-plane is measured in pallet. The efficiency of pallet needs to be considered with respect to its volume and weight. There are some guidelines about orders of priorities and regulations in the military air transportation. However, there are no methodologies which can raise the efficiency of flight scheduling using Operations Research (OR) theories. This research proposes the effective computing methodology and the related heuristic algorithms that can maximize the effectiveness of the path routing model.

China has increased 10 percent every year since 1978. In particular, development and growth of Chinese ports make a remarkable in that the marine and coastal transportation handles the 90 percent of export-import cargo. This growth is beginning to threaten Korea's ports which are striving to become the hub of Northeast Asia logistics. Furthermore, the hub strategy of Northeast Asia is closely related to transshipment cargo invitation. The results of documents research indicate Busan and Gwangyang ports play an important role as an intermediate stopover between China and America. The ways to achieve transshipment cargo invitation are the construction of transshipment system based on the supply chain between korea and china, the maximization of trading volumes creation, equipment of ports infrastructure, and the constructions of the rail, road, coastal transportation infrastructures.

In this study, we researched a space allocation method of emissions from domestic coastal shipping (passenger ship, cargo ship, fishing boats). We were building a geographic information data that is used in GIS for emissions of space allocation, and presented a methodology capable of performing the space allocated for each grid by calculating the emissions. Passenger ships were assigned emissions of routes each the ship that operated at a fixed. Emissions of crusing mode of cargo ship, was equally assigned to the safe operation line, which is defined for domestic cargo ship. Also, Emissions of maneuvering (moving into or out of port) and hoteling (operations while stationary at dock), was assigned in consideration of anchorage in the major port. Fishing boat was evenly allocated monthly emissions in the country every month fishing grounds formation zone. Based on these results, it tries to provide the basic data that can be used when you want to create a local government measures to reduce scenario in the future.

The development of logistics technology due to the 4th Industrial Revolution and logistics 4.0 has changed the logistics environment from offline to online, and the growth of the online market has accelerated due to the recent increase in non-face-to-face delivery due to COVID-19. Such growth in the online market has expanded the logistics market for delivery, and contributes to creating an advanced logistics ecosystem as last mile services and logistics technologies begin to grow together. As traffic and environmental problems arise as a result, interest in transportation means of cargo increases, and changes to cargo electric vehicles and delivery cycles are being considered. However, since mass transportation of transportation focused on terminal delivery such as cargo electric vehicles and delivery cycles is limited in handling large quantities in urban areas, methods for efficiently transporting cargo while considering the environment are being devised. In order to solve such environmental problems and increase the efficiency of logistics delivery in urban areas, technologies using underground spaces based on existing urban railroads are being developed. In this study, a study was conducted on the establishment of evaluation criteria for selecting a test bed, which is a space for applying the system.
