  • 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.

  • Hai Phong is the important transportation hub of the northern Vietnam with many advantages. Hai Phong can connect with orthers provinces by road, railway, airport, seaport system and inland waterway. So far, Hai Phong is develop so fast However, Hai Phong's logistics services are still low level and less competitive. The human resources are lacking of experiences and also low quality, the logistics enterprises are small, low capital and they can not compete with foreign companies. Further more, the infrastructure are invested but there are still have some problems inside. This paper has assessed and systemized the situation of development of Hai phong.

  • Inchon International Airport (IIA) is one of many new airports being constructed in the Asia Pacific region. IIA is located at the center of Northeast Asia connecting 43 major cities within 3.5 hour flight. With the sate-of-the-art airport facilities, IIA will also have the diverse functions of a modern airport for international business, where airport users can work and relax at the same time. It will be built for the multifunction of Pentaport - Airport, Businessport, Teleport, Seaport and Leisureport. IIA will be a leading hub airport for Northeast Asia in the coming 21st century. This paper will focus on the development plan for Inchon International Airport and its current status.

  • This paper presents a position control of a platform at the seaport cargo handling system. After brief description of the operating principles of the cargo handling system, the governing equation of the moving platform is derived. The equation is described in the state space model, and a robust H$_{\infty}$ controller to achieve position tracking of the moving platform. which can carry 200ton of containers, is formulated. In the synthesis of the controller, the weight of the container is treated as uncertain parameter. Both regulating and tracking control responses are analyzed for the loading and unloading procedures of the proposed automatic cargo handling system.

  • Recently we have seen a noticeable trend in ports to establish port clusters. Despite this trend, little research has actually been undertaken to fully define and analyse port clusters. A couple of exceptions have descriptively defined port clusters but the boundaries of port clusters are not apparent. Therefore, the aim of this paper is to define port clusters in terms of set theory and in particular look at them in terms of their distinct characteristics and system boundaries. The main concern of this paper is that there is a need to distinguish, from a system and a competition perspective, between port clusters, ports, maritime clusters and port ranges. This paper proposes a conceptual model relevant to the relationship among port clusters related assemblages and that has been applied to the north western europe region This model suggests six levels of competition that will help port authorities and government to develop appropriate policies and strategies for port operation and port industry.

  • After September 11, 2001, the United State's Customs and Border Protection (CBP) has set up inspection stations in seaport terminals. The inspection station, however, may directly and indirectly affect delay time in the seaports, increasing by especially high and severe level of security. This paper studies for a methodology to analyze container delays versus security incurring by the various layouts of the inspection station in the United States.

  • Recently, the cluster-based industrial policy has become a powerful policy tool for strengthening the competitiveness of nations, industries and firms. The concept of cluster develops as firms choose to locate in each others proximity. Cluster concept can be usefully applied to analyze cluster of port-related activities. Port cluster can be used as a systematic foundation for providing one-stop value added logistics service to its customers. The main purpose of this paper is to suggest a way for establishing the port cluster in Korean seaport. For this aim, the paper defines a concept of port cluster and examines the its necessity. And the procedure for establishment of port cluster in Korea is proposed. In addition, the paper analyzed the port cluster structure-conduit-performance. Especially, the role of port cluster's participants, central and local government, universities and related R&D institutes, and private companies, are suggested respectively. As a conclusion, policy suggestions for the establishment of port cluster in Korea are suggested.

  • The efficiency of port operations is an important indicator of port development. Moreover, there is excess handling capacity in Chinese ports, which results in a slower speed of development. Under the detrimental environment of the international shipping market, it is necessary to improve the operation efficiency of ports for long-term development. This paper provides an assessment of the competitiveness of Chinese seaport companies using the Boston Consulting Group's matrix, and efficiency measurements using a data envelopment analysis and the Malmquist method. This analysis showed that highly efficient companies reformed their development strategies, which should be a solution considered by less efficient companies, such as Shenzhen Yan Tian Port Holdings Co., Ltd.. Although, having high throughput should be reformed in the investment structure. This research will assist port companies in gaining effective operating experience, and governments in establishing strategic planning to enhance the efficiency of port development.

  • India has occupied the most important position of sea trade in the entire South Asian region since the beginning of maritime trade. The extensive maritime trade network between the Harappan and Mesopotamian civilizations as early as the $3^{rd}$ millennium BCE is testimony to the long maritime trade history of India. The Harappans constructed many seaports including the first high-tide dockyard in the world for berthing and servicing ships at the port town of Lothal, Gujarat. From the dawn of the historical epoch, the maritime trade network of India expanded extensively. The long 5422.6 kms coastline of the Indian mainland (excluding the coastlines of the Andaman and Nicobar islands and the Lakshwadweep Islands) is well known for its several seaports manly located at river mouths or outlets to the sea. The main objective of this paper is to discuss in detail all the major ancient seaports on the eastern coast of India and their maritime trade activities. The narrative of these ports is based on archaeological explorations and excavations, foreigners' accounts, Indian literary sources, inscriptions, archival materials, and the field study and personal observation of the author.

  • This study aimed to determine relationships among risk factors influencing container port operation using Bayesian network. Risk factors identified from prior studies were classified into five groups: human error, machinery error, environmental risk, security risk, and natural disasters. P anel experts discussed identified risk factors to fulfil conditional probability tables of the interdependence model. The interdependence model was also validated by sensitivity analysis and provided an interrelation of factors influencing the direction of each other. Results of the interdependence model were partially in line with results from prior studies while practices in the global port industry confirmed interrelationships of risk factors. In addition, the relationship between top-ranked risk factors can provide a schematic drawing of the model. Accordingly, results of this study can expand the prior research in the Korean port industry, which may help port authorities improve risk management and reduce losses from the risk.
