Major nations undergone grand national strategy regarding Eurasia such as China's One Belt and One Road Strategy and Korea's Eurasia Initiative owing to Eurasia's regional importance. Korea's Eurasia Initiative aims to make one continental, creative continental, peaceful continental with intra-Eurasian nations as grand national strategy is based on creative economy, undertaken by President Park's Government for the future of Eurasia after the Northeast Asian logistics hub strategy. Eurasia Initiative includes logistics network project as an important one which consists of Eurasia Friendly Express, Rajin-Hassan logistics project, the Arctic Ocean route project and Rail transport network project. The success of Eurasia Initiative depends on North Korea. The purpose of this paper is to contribute to the improvement of prompt logistics network by networking main rail transport and other transports such as inland waterway transport and air transport by studying the current situation of Eurasia Express project, including rail transport network and the efficient methods of Eurasia logistics. The efficient methods of rail transport network under the Eurasia initiative are construction of multimodal logistics network connected with rail, international cooperation for logistics standardization in Eurasia, Eurasia nations' subscription of logistics-related conventions and projects performance based on these conventions, etc.

In this paper, I explain the situations and problems which are focused on the rail freight system. We have a many problems, which have been showed the long freight logistics time, and inadequate fare system. And rail freight system does not have a efficient marketing system, and unit load system. Therefore rail freight has been decreased modal share, which is estimated from 9.65% in 1995 to 6.25% in 2001(ton base). Recently, EU nations and America rail freight system reveals a good outcome, which keeps the balance in the black. The main factors which go into the black, is the enlargement the investment in rail freight and efficient management focusing on the unit load system, fare system, and personnel management. I suggest the several improvement ways, which will be helpful to advance the rail freight system. Fistly, I suggest the speed up the freight rail and efficient fare system. Secondly, I propose the unit load system and the regulation the truck focusing on curtailment of the social cost. Lastly, I make an overture of establishment the comprehensive logistics system.

The Korean railroads' logistics are facing the important turning points by the connection of. South and North Korean railroads, and the commercial opening of the High Speed Rail. These two factors demand several plans for the development of railroads' logistics, in which intermodal transportation with the others modes is wholly studied. In this respect the case of port of Hamburg, Germany, where railroads are completely integrated in the port, will permit the Koreans some useful lessons for the future of railroads' logistics.

This paper considers the rail crane scheduling problem which is defined as determining the sequence of loading/unloading container on/from a freight train. The objective is to minimize the weighted sum of the range of order completion time and makespan. The range of order completion time implies the difference between the maximum of completion time and minimum of start time of each customer order consisting of jobs. Makespan refers to the time when all the jobs are completed. In a rail freight terminal, logistics firms as a customer wish to reduce the range of their order completion time. To develop a methodology for the crane scheduling, we formulate the problem as a mixed integer program and develop three metaheuristics, namely, genetic algorithm, simulated annealing, and tabu search. To validate the effectiveness of heuristic algorithms, computational experiments are done based on a set of real life data. Results of the experiments show that heuristic algorithms give good solutions for small-size and large-size problems in terms of solution quality and computation time.

These days, environment has became more and more important global issues including Climate Change Convention which 40 developed countries have to decrease CO2 emission by 5.2% compared with 1990 emission. Rail transport in Korea are becoming more important as a solution for environment and energy owing to high energy consumption country. Rail transport is environment-friendly mode compared with truck mode (energy consumption 14.2 times, CO2 emission 13.4 times), but it has door-to-door problem and "DMT transport system for rail logistics" can be a solution for this problem and this system can lead to environment-friendly transport mode by rail. This study will review the background of worldwide and Korean DMT system, customers' needs, and analyze transport cost with other transport mode. Through theses kinds of review and analysis, this study will propose DMT terminal, DMT rolling stock, and DMT operation system.

Interest about Modal Shift is not being decreased, and it is drawing limelight as green logistics which meets low carbon green growth of National development vision. As an effect of Modal Shift, not only reduction in CO2 emission but also reduction in social cost, logistics cost etc. are being discussed. However, until now research about its practical transformation effect has been scanty. In this study, the actual expenses via CO2 emission, social cost, and logistics cost etc. by road transportation and rail transportation of container cargo with Origin/Destination between Busan-Kyeonggi Area were calculated and we propose beneficial effects when transportation mode is transformed from road to rail with Scenario Planning.

The success of road haulage, in dominating the surface movement of freight, is now threatened by increased traffic congestion, falling average motorway speeds and rising in logistic costs. As a result, Government as well as companies, which use or operate logistics service, is now looking to rail to provide an alternative. First, we surveyed the bottlenecks and desired betterments to rail transport, which were indicated by rail and road transport users. Through the analysis of customers' needs survey. this paper is focused in the basic framework fur the rail freight transport, which could be helped to promote the efficiency associated with moving freight by rail.

Railroad is considered as an eco-friendly transportation mode because it emits lower greenhouse gases and air pollutants and consumes less energy compared to trucking. To promote rail freight, many countries have implemented various policies, while South Korea has implemented few substantial policies. This study aims to compare and analyze rail freight policies of various countries in order to suggest policy implications to South Korea. We analyze relevant policies of 9 countries; these are classified into 5 categories, and we provide policy implications for facilitating rail freight infrastructure and equipments, grants for the transportation cost using freight rail, and road freight restriction policy.

It is essential to connect the railroads between South and North Korea in order to the implementation of the Eurasia initiatives and prepare for the normalization of the economic cooperation between south and north Korea as well as the unification. This study provides the strategy to establish the rail logistics network for the normalized trades between south and north Korea, and the accommodation of the logistics demands to China and Russia. The alternative routes were designated and the costs for the rehabilitation were estimated, and suggested the priority for the investment. The Trans-China Rail is prior to the Trans-Siberia Rail in terms of the utility for the logistics and the political value. In connection to the TSR, it is desirable to pass the Seoul-Gyeonggi area where the demand is greater than the other area. This route is limited by the restriction in the capacity, then the Gyeonggi Ring Rail route may be necessary.

This paper considers the problem of scheduling loading and unloading operations of a crane in a railway terminal motivated from rail-road container transshipment operations at Uiwang Inland Container Depot (ICD). Unlike previous studies only considering the total handling time of containers, this paper considers a bi-criteria objective of minimizing the weighted sum of the total handling time and tenant service time. The tenant service time is an important criterion in terms of terminal tenants who are private logistics companies in charge of moving containers from/to the terminal using their trucks. In the rail-road container shipment yard, the tenant service time of a tenant can be defined by a time difference between beginning and finishing loading and unloading operations of a crane. Thus, finding a set of sequences and time of the crane operations becomes a crucial decision issue in the problem. The problem is formulated as a nonlinear program which is improved by linearizing a nonlinear constraint in the model. This paper develops a genetic algorithm to solve the problem and performs a case study on the Uiwang ICD terminal. Computational experiment results show that the genetic algorithm shows better performance than commercial optimization solvers. Operational implications in terms of tenants are drawn through sensitivity analyses.
