In these days, 8000TEU container ship service launches in shipping service at latest based on the economy of scale, unit cast related with ship operation on ocean decreases in proportion to increase of ship scale and mega ship over 10,000TEU is on planning. This paper is analyzed the economic efficiency for reduction qf calling port in the operation cost, port chnrge, feeder cost, etc by an empirical analysis.

This study is to contribute to create favorable conditions for developing the new port in a timely and as well helps to propose role and establish status of incheon port in the future by reviewing port facility capacity of Incheon Newport, applied trigger rule reasonably. By applying trigger rule with annual growth rate(11.4%) between 2001 to 2009 rules it will be 18 berths reducing 2 years for completion date than annual growth rate(9.4%) forecasted by Ministry of Land, Transport and Maritime Affairs. This paper first suggests the tri-ports policies including Incheon new port, Busan port and Gwang-Yang port and creating favorable conditions for the early completion and lastly attracting high valued-added transshipment cargo for developing incheon new port in a timely.

In this paper, practical problems for current feeder service between Busan port and west coast of Japan were extracted through in depth interviews with Japanese feeder vessel companies, shippers, and port authority based upon which major criteria (elements) for improvement of the feeder network are structured in hierarchic order and weighed relative importance through AHP method. From the questionnaire answered by Korean and Japanese port users and experts the weights of criteria were calculated and the shipping service was ranked the first by both parties with 0.235 and 0.217, respectively. The port service and support system ranked the second and the third, whereas the port marketing was shown to be the lowest of all. Considering the overall weights, the increase in a port loading and unloading speed of port service was followed by provision of dedicated deck for feeder vessel of port facilities for Korean respondents. Therefore, speed up of the port operations and providing docks for feeder vessel are to be firstly provided for more efficient feeder operations, which would be the basis for the construction of optimal transportation network.

Most q the domestic container terminals are inferior to throughput q container. The reason why they have the difference between the handling capacity q planed quay and its real. By putting into quay handling equipment, the productivity of quay can be improved, waiting rate q the ship can be lowed. This paper suggests more resonable terminal construction, throughout comparing with previous construction way, improved handling capacity and the economical efficiency of equipment costs, labor costs, construction costs, operation costs on change of terminal size by adding the equipment.

It is connected with various gauges existing in Euro-Asian continents. Such differences impedes the operation seriously as on the contact of railway tracks of different gauge the cargo must be either transshipped or the running assemblies of rail vehicles must be exchanged. Those operations are costly, time-consuming and require extended infrastructure together with very expensive storage and transshipment facilities at border-crossing point. Moreover, those operations extend transportation time considerably. Therefore, effectiveness of railway transportation systems significantly depends on track gauge change 1435/1520mm, which connects with complicated handling-shifting operations. The paper concerns assessment of effectiveness in strategical rail systems with gauge changing. The paper presents short description of transport system with gauge changing and initial assessment of shifting technologies. Method of system assessment comparison based on Life Cycle Cost model is described here as well.

With trend of container ships becoming larger and faster, the environment surrounding ports in North-East Asia is rapidly changing. Korea's largest port of Busan processed more than 10 million 20- feet equivalent containers in 2003, surpassing the 10-million TEU mark for the first time in its three decades of operation. However, the Port of Busan , the world's third-largest port in 2002, was eclipsed by Shanghai since July in 2003. The first massive strike of truckers crippled the Korea's logistics system in May and in September, the Port of Busan suffered from the second strike of truckers and damage by a powerful typhoon. By contrast, the port of Shenzhen in China increased its container-processing volume by 39.9 percent to 10.65 million TEU in 2003, and Shanghai, which passed Busan in terms of container volume in the middle of last year, further consolidated its position as the world's No. 3 port with an annual volume of 11.28 million TEU. After all, Busan recorded an annual container volume of 10.40 million TEU, slipping to fifth in rankings in 2003 and Busan's bid to become a Northeast Asian hub has suffered a further setback as these chinese ports overtook the port of Busan. But the port of Busan is located in the main trunk liking North America, Europe and South-East Asia. Once the project of Busan Newport is accomplished and the railway between South and North Korea is connected to TCR and TSR, the Port of Busan will have the most potential to become the international logistics center as the starting point of the land and sea routes encompassing all over the world.

Recently the increase in the exchange of goods between Europe and Asia caused by social and economic factors creates good opportunities for railways. At the same time, however, it becomes an enormous challenge for railway transport. There are different rail track gauges (i.e narrow/standard/broad gauge) on the continental transportation between Korea (TKR) and Eurasian (TCR/TSR). The existence of various track gauges is one of obstacles preventing the smooth flow of goods by rail. The transferring process system from one track gauge to another could vary with the types of cargo. Service operation of these systems has a decisive effect on working time and cost of storage and transshipment facilities at border crossings. In relation to the above-mentioned factors, it is important to examine the comparison between different methods of transferring goods in different track gauges. In this study, it was performed to evaluate the effectiveness of continental railway transportation systems through analysis scenarios and to suggest technical factors of them.

Trade turnover between asia including our country and China and South America including Brazil the Chile is increasing continuously. That key item is diversified very from the raw materials to the agriculture and marine products, the industrial product and the mineral. The international transportation of these freight mainly depends in the aircraft and the container liner. But, in order to pass through the most various port of call is makes transshipment cargo and the long lead-time. so the goods expense of the style increases. The research proposed logistics network's construction between the main harbors of Korea and Ecuador. These nation according to great circle navigation is contiguous geographically in order to confront Pacific Ocean. These nation is contiguous geographically in order to confront Pacific Ocean by the great circle navigation. Specially Korea will become the hub-port of Northeast Asia and South America, which is caused by direct logistics lines's establishment.

This paper focuses on measuring the efficiency of container yards in container terminals in Busan and Gwangyang using Data Envelopment Analysis (DEA) approach. It analyses the relative efficiency of 11 container terminals based on the data for the period between 2006 and 2009 to offer a fresh perspective. The applied framework assumes inputs to be container cranes, transtainer cranes and yard tractors and output as container transshipment volume. Through the analysis, the differences between the impact of using of container cranes, transtainer cranes and yard tractors, top handler & reach stacker on container yard efficiency are measured. Moreover, the associations between the three input factors are analyzed as well. This paper also employs heteroscedastic Tobit model to show the impact of explanatory variables on container yard efficiencies. I took into consideration the strategies for operation of container cranes, transtainer cranes and yard tractors in container yard.
