OPTIMIZING THE TRANSPORTATION OF INTERNATIONAL CONTAINER CARGOES IN KOREA

This paper considers a multimodal transportation problem, which is the problem of determining the transportation flow, i.e. volume of container cargoes, and the transportation mode in each trade route, for the objective of minimizing the sum of shipping and inland transportation costs. The problem takes account of two restrictions: maximum cargo volumes capacitated at each seaport and maximum number of vehicles available at each transportation mode. To solve optimally the problem, this paper employs a mixed integer programming, which is an operations research technique. A case study is performed on the container cargo data in Korea and we draw several implications to improve efficiency in the transportation of international trade cargoes in Korea.

Maritime logistics in the global supply chain

As world economies become ever more globalised and interlinked, international logistics and maritime (shipping and port) industries are experiencing challenges as well as enjoying greater business ...

Impacts of the ECFA on seaborne trade volume and policy development for shipping and port industry in Taiwan

This paper uses a global computable general equilibrium model, global trade analysis project and a value-to-volume conversion to arrive at quantitative estimates of the new seaborne cargo volumes resulting from a free trade agreement between Taiwan and China, namely, the Economic Cooperation Framework Agreement (ECFA). The approach is designed to model asymmetric impacts of tariff removal and economy-wide interactions caused by the ECFA arriving at estimation in cargo value flows. Then a scientific approach is developed to convert the estimated cargo value flows into volume flows. The analysis concludes that in terms of total trade value, the ECFA liberalisation would induce a trade creation effect across the Strait of more than US

4.67 billions). Regarding the converted trade volume, the exports of uncontainerisable and containerisable cargo to China increase by 0.37 and 5.12 million tons (0.43 million TEUs), respectively. The increases in imports from China are relatively minor at 0.19 and 0.75 million tons (0.06 million TEUs) of uncontainerisable and containerisable cargo. Policy implications and suggestions for shipping and port industry are provided accordingly.

A New Lease Charging System for Busan Container Terminals: a Historical Case Study

Abstract This paper explores the external costs of domestic container transportation in Taiwan by analysing the origin and destination of current container cargoes. After reviewing an extensive literature survey of methods of external cost, a comparison of external costs between trucking and short sea shipping (SSS) by corridor is made by using a model developed in this paper. Based on the findings that external costs of SSS are considerably lower than truck transport and can be a viable alternative to current domestic container cargo transportation, we discuss the significance and managerial implications of SSS from the perspective of green logistics. In so doing, a top‐down approach is employed for developing government policies, which aim to not only reduce the external costs of domestic container transportation but also promote SSS in Taiwan.

To alleviate harm to the environment, short sea shipping (SSS) is gaining popularity in transportation policy formulation as an alternative transport mode for ecofriendly and cost-efficient transportation. There have been no studies of how to optimize intermodal container movement incorporating environmental aspects into SSS networks. This paper analyzes an intermodal transportation problem of international container cargoes while incorporating the external costs of the modes into an optimization model in South Korea. The objective of the problem is to minimize the total logistic costs, that is, shipping and land transportation costs, as well as external costs such as air pollutants (particulate matter, nitrogen oxide, sulfur dioxide, and volatile organic compounds) and greenhouse gases (carbon dioxide). The results of the model show a strong foundation for encouraging more environmentally friendly modes, such as SSS and rail, and a well-balanced modal shift if transport policy is formulated in this direction.

Evaluation of the service quality of container ports by importance-performance analysis

Freer South-South trade has been recognised as a vital engine for the developing countries to reap the maximum economic gains from multilateral trade liberalisation. One of the latest developments which draws considerable attention is the proposed free trade agreement among India, Brazil, and South Africa, namely IBSA, given the fact that the three countries are amongst the leading economies in the continents of South Asia, South America, and Africa, respectively. This paper applies a global computable general equilibrium model, Global Trade Analysis Project, and a converting approach to quantify the impacts of the IBSA trade liberalisation on seaborne cargo volumes. The major advantage of the GTAP model is that it can capture the effects of economy wide adaptation and asymmetric structure change in exports and imports caused by trade liberalisation. Based on our numerical results, removing high tariffs in the South-South trading routes reduces the significance of geographical distance in determining South-South trade patterns, and promotes distant trade with faraway countries.

Overview of interport competition: Issues and methods

This paper aims to examine the inherent problems in the old lease charging system at Busan container terminals, to explore the factors and rationale, both theoretically and practically, for developing a reasonable lease calculation model, and to articulate the design of an efficient lease charging system to enhance throughputs. On the basis of the above achievements, implications for the newly introduced lease charging system of the Port of Busan based on the flat rate method are drawn.
