  • The purpose of this study is to analyze the economic aspect of sea transportation system between Inchon and Youngjong island in which Inchon international airport is being constructed. Total demand of sea transportation arising from in the airport and Yongyu Muwi leisure complex was estimated. To select optimum transportation route, environmental conditions in and around Inchon harbour and Youngjong island including the change of water depth by tide current, fog, rain, wind adn typhoon, ets., were investigated. The preliminary consideration on ships (size, velocity, transport capacity, price), routes, operational modes, terminals and berthing facilities were carried out. The transportation cost per passenger by sea transportation system was estimated to compare with that of land transportation system. It was found that sea transportation system proposed is competitive to the transportation system.

  • This article summarizes the results of sea transportation load measurements, which will be used as the reference to the sea transportation environment condition for the launch vehicle of KSLV-I. KSLV-I will be transported by Sea from Pusan to the NARO space center in Gohung, Chunnam province. Since the vibration load condition during sea transportation is considered as one of the important design parameters of KSLV-I and its transportation means, it is necessary to directly measure the environmental condition of sea transportation loads prior to establish the sea transportation plan in detail. This material includes the measured data of 3-axis linear accelerations and 3-axis angular rates on the board of a barge-ship, which is towed by a tug boat during shipping operation. This barge-ship is same class with one which will actually carry KSLV-I. The results show that the measured load condition during sea transportation is not severer than the reference data of MIL-STD-810F and Zenit-3SL launch system.

  • Recently, the coastal transportation of the Yellow Sea is increasing due to the vastly expanding trade among countries surrounding the Yellow Sea. As the 50 percentages of the total domestic container transportation are concentrated on the National Capital region, the traffic congestion in the key land transportation routes brings about the weakening of the global competitiveness. In this study, the efficient barge systems for sea-river shipping of the Han-river, the Kyongin canal and coastal ways of the Yellow Sea are considered based on the criterion of canal and cargo volumes. To find the efficient barge system of the model barge in the Kyongin canal. the transport efficiency factor and transport ability of each barge system with the variation of sailing speed and length are calculated.

  • This paper considers the problem of determining the cargo flow and the transportation mode in each trade route while satisfying the demand. Especially, the problem incorporates short sea shipping in Korea, which is becoming more important in order to improve efficiency of Logistics. The objective is to minimize the sum of shipping and inland transportation costs. To solve optimally the problem, this paper employs a linear programming model, which is an operations research technique for optimization. The problem is formulated by extending the well-known network design problem by considering capacity at seaport and limitation of total number of vehicles. The model is solved using CPLEX, a commercial linear program software. The test results using a real cargo flow data in Korea show that the model represents closely the real situation.

  • Trade between Korea and China was 372million dollars accounting for 1.56% of total in 1988 and has been increased to 23,689 million dollars occupying 7% in 1997, which implies 32.2% increase on average per year. This trend will continue dramatically and consistently as China's open policy toward the world accelerates and korean companies advance into chinese market. The main trade routes are with marine transportation between korean west sea area and chinese San-Dong peninsula around east sea. However, due to the increasing traffic congestion on main roads connecting harbors and main consumer cities and capacity problem in west sea harbor areas, the logistics cost have been increased resulting in losing competitiveness of freight trade. Therefore, these road-oriented inland transportation means need to be changed to rail transport system to reduce congestion and to conserve natural environment. To achieve this scheme, efficient intermodal transportation system connecting road and rail should be constructed. These combined system will ensure timely delivery of goods and consequently the customers would make proper transportation schedule for the import/export goods in advance. Especially, combined transportation of Railroad and train ferry would cope with the logistics problem and this system would be efficient means for trade with not only China but further with many adjacent countries in central asia such as Kazakhstan and Uzbekistan

  • The demand of international intermodal transportation is continuously increasing in accordance with a changing environment on international logistics, Under this circumstance, the Sea&Air intermodal transportation, combined by sea-based and air-based transport, has a potential growth in the future. After analyzing routes for Origin/Destination and implementing portfolio analysis, finally, this research aims to propose alternatives to create additional customers(or cargoes) for the Sea&Air transport. As a result of the analyses, China appeared to be a major customer of the Sea&Air transport in Korea because some of the Chinese areas - i.e. Qingdao, Shanghai, Weihai and Yantai - account for 88.1% of the total throughput. In general, this indicates that it would be more efficient to establish specific strategies targeting those major areas. Excluding the four areas, most of the other area, have much less demands and are relatively unstable. The demands, growth rates and market shares especially in Vladivostok, Dandong and Tianjinxingang are on the decrease, and therefore, stable strategies seems to be appropriate than aggressive strategies for these areas.

  • It have been known that the probability of accidental happening in towing-barge is higher than that of other merchant vessels. Because the towing-barge is restricted in thier manoeuvring ability due to its towingline. A report from ministry maritime affairs and fisheries said that the rate of collision accident for towing-barge is $40\%$ high tlnn other transport system in sea. A number of researches have been carried out to improve the safety policy in the towing-barge sea transportation system by the gorvernment. This study examined the safety status in domestic towing-barge sea transportation system The registration status, safety operational policy and post accidental data were also examined A survey research of experts relating to towing-barge operation also was carried out to find the detailed of safety status. This study would be applicable to set up safety policy for towing-barge marine transportation system.

  • As the globalisation of corporate's managemental environment, all parts of logistics such as procurement, production and sales are globalized. The ways of transportation in Korea and Japan, where are difficult to use land-transportation, are sea-transportation and air-transportation. Sea & air is a way of the international transportation which is combined by Sea and Air to reduce the transportation fee and shorten the delivery time. The main body of multimodal transportation service is the corporate, actual carrier who undertakes the actual transport. It is essential to establish service quality to maintain their going concern. In other words, the actual carrier has to emphasize the importance of service quality to forwarder tan any other business conditions. In this study, we examine the determinants of service quality for actual carrier in multimodal transportation. Through the multi-regression analysis based on SERVPERF by Cronin and Taylor (1992), we analyze the service quality dimensions of actual carrier. Also we examine the relations between the determinants and customer's satisfaction. Using statistical hypothesis testing, the determinants of service quality are reliability, responsiveness, assurance, tangibles, and we could look into the factors which the actual carrier should control with priority.
