  • In line with the trend of global transport volume which has increased rapidly over the years, internal transportation in seaports is always conducted with high frequency. Thus, there is always much potential for traffic jams as well as high transportation costs and emissions. Many efforts have been initiated to streamline the inter-terminal container transport (ITT) through the development of automated vehicles and equipment as well as using private transport facilities to overcome these limitations. The purpose of this paper to develop a framework to design, analyze, and validate the efficiency of a new ITT system in a port area based on the monorail network and automatic vehicles. First, the number of shuttles and loaders was determined depending on the transport demand scenario. Next, a simulation model was applied to evaluate the system performance as well as gain more insight into the working process of the ITT system. Finally, by setting goals for the performance indicators, the results showed that the system was highly efficient with 100% of the containers delivered to their destination on time. Besides, a series of other performance tracking was provided to provide insight into the system's capabilities.

  • Recently, there has been a noticeable increase in the number of tourists in islands that are well-known for their natural landscapes. It is expected that this number will go up steadily, due to the increase in per capita income and leisure time. Regarding tourism transportation, utilizing linkage transport between coastal passenger terminal and inland transport system is crucial. However, the existing system does not measure up to the expectations. This is attributable to the fact that the distances between coastal passenger terminals and inland transportation terminals are too far. Also, the current public transportation system lacks support and needs to take the role of connecting the two terminals. This study shows how coast-inland linkage transport system should be reformed in order to promote island tourism. It focuses on building linkage transport system and minimizing walking distance. Also, adjusting passenger ship schedule to the characteristics of island tourism is needed. For the sake of passengers, coastal passenger ship fare should be reduced, and integrated transport information should be provided.

  • The Korean government establishes a strategy to develop the Busan New Port as a world ranking two transit-oriented port. This paper aims at presenting an efficient inter-terminal transport (ITT) system in the Busan New Port as a method of achieving the government strategy. First, it presents results of long term forecast for the inter-terminal transportation volume in the port. Second, it proposes two systems to treat ITT in the port; Double stack Multiple Trailer System (DMTS) and Rail-based transportation system. The implementation methods in the port are introduced in detail for the both systems, and the required number of the systems and costs are calculated for implementation of both the systems. B/C for DMTS is analyzed to 3.7, moreover unit-fare per [$ton{\cdot}km$] can is lowered to 67% against current fare. DMTS is shown to highly potential for efficient ITT in the port.

  • As network traffic is dramatically increasing due to the popularization of Internet, the need for application traffic classification becomes important for the effective use of network resources. In this paper, we present an application traffic classification method based on fixed IP-port information. A fixed IP-port is a {IP address, port number, transport protocol}triple dedicated to only one application, which is automatically collected from the behavior analysis of individual applications. We can classify the Internet traffic more accurately and quickly by simple packet header matching to the collected fixed IP-port information. Therefore, we can construct a lightweight, fast, and accurate real-time traffic classification system than other classification method. In this paper we propose a novel algorithm to extract the fixed IP-port information and the system architecture. Also we prove the feasibility and applicability of our proposed method by an acceptable experimental result.

  • Being situated at the key point of northeast asia, the port of Inchon as an entrance to the captial city, Seoul is expected to play in marine transportation in Korean Pennisular on the verge of its reunification. In this thesis, inner-lock physical disstribution system of the port was analyzed, which treats more than 82% of total incoming and outgoing cargoes. The overall findings are as follows; 1. In thet viewpoint of physical distribution system of the port, it takes disadvantages of accessing to inner lock berth due to such natural restrictions as tides, passing the lock and so on. And insufficient port facilities as a whole, causes delay in quay-handling, transfer and storage, also facing with serious congestion in inland transport on the road. 2. It was revealed that the port facilities are insufficient yet in spite of its improved productivity by means of raising the effectiveness of port operation and of installing advanced cargo handling facilities. 3. In order to enhance the effectiveness of inner port physical distribution system , the improvement of lock facilities, expansionof port facilities and more effective terminal operating system are crucial. 4. To ensure the measures to solve the above problem, existent outer-lock ports such as Inchon Sourthern-port and Northern-port are necessary to be redeveloped more positively , otherwise a new port at outskirt of the city should be developed to ensure free connection to inland transportation.

  • Demand for Sea & Air intermodal transport has increased between north-China costal cities and Incheon since China's international airline network was not established completely. It will be big opportunity for Incheon to be logistics hub of Sea & Air intermodal transport in the north-east Asia, musing large sea-air cargoes to be transferred at the port of Incheon. Therefore, this study aims to propose competitive strategy on Sea & Air intermodal transport system of Incheon. In this analysis results, this paper shows that sea & air cargoes rather from china to U.S. than from China to Europe is very significant, considering geographically for Incheon and is also devote to not only providing high quality services but also activating RFS(Road Feeder Service) system, enlarging toward Shanghai, Weihai, and Yantai.

  • The logistics industry is growing rapidly with China's economic development in recent years. Particularly, the intermodal freight system is becoming the main issue to reduce the logistic costs under the situation that the quantity of cargo transported between Korea and China is continuously increasing. Shift from road transportation to eco-friendly modes such as rail and coastwise shipping is also increasing. The present study suggests technical aspects related to the implementation of intermodal transport system centered on train ferries between two countries with already employed Chinese infrastructure into consideration. Technical assessment of intermodal train ferry system entails not only the vessels but supporting facilities and technologies as well. Port and rail facilities and operating skills for efficient modal shifting, and their standardization is indispensible to the realization of an intermodal train ferry system between the two countries.

  • This study conducted a SWOT/AHP analysis to prepare a developmental strategy for Gwangyang Port. The SWOT analysis is used to analyze internal and external environment in the strategy stage. The SWOT/AHP analysis was proposed by Kurttila et. al. (2000) to improve usefulness of the SWOT analysis. The results of the SWOT analysis confirm what factors are present in the SWOT group. Therefore, when it is combined with the AHP analysis, it evaluated the relative importance of factors gained from the SWOT analysis and used them to develop strategies. To sum up the results, in the SWOT group, opportunity, strong points, threat and weak points were relatively important in a good order. In respect to factors of the SWOT, for a factor of strength, reasonable freight cost, good port site, and broad hinterland were relatively important. As to factors of weakness, absence of an efficient customs system, a complex transport system and port personnel were relatively important. As to factors of opportunity, an improved transport system through building various infrastructures, consistent development of a connected industrial complex, and increased cargos in northeast area were relatively important. As to threat factors, an improved transport system through building various infrastructure, competition with neighboring ports and small complex transport companies were relatively important.
