현재 화차를 이용하여 화물을 운송하는 철도 물류는 국내 화물 물동량의 $10{\sim}20%$ 가량을 담당하고 있다. 철도물류 사용자인 운송사(화주 포함) 또는 내륙화물기지는 철도물류 업무를 처리하기 위해 EDI(XML)를 통해 문서를 전송하거나 WEB을 통해 데이터를 입력하고 있다. 그러나 점차 e-비즈니스 환경이 활성화됨에 따라 기존 철도물류 업무에 대한 개선이 요구되고 있다. 또한 확장성 있는 ebXML 기반의 스키마 형식의 사용이 확산되면서 DTD 구조의 전자문서를 XML 스키마 형태로 개선할 필요성도 제기되고 있다. 본 논문에서는 철도물류업무 개선을 위한 철도물류 정보 표준을 연구하고자 한다. 이를 위하여 기존 비즈니스 프로세스를 재정의 하여 불필요한 업무를 개선하고, 비즈니스 프로세스 모델링으로 철도 물류 액티비티를 정의해서 최종 정보 모델을 도출한다. 또한 도출된 정보 모델에 따라 새로운 전자문서를 설계할 수 있도록 비즈니스 정보 개체를 정의하였으며, 철도물류 정보시스템의 개선된 구조도 제안하고자 한다. 이를 통해 철도물류 비즈니스에 효율적이고 확장성 있는 업무 절차를 제공할 수 있을 것이다.

In 21th century, high oil price and environmental pollution appeared by serious social problem. It brought important change of logistics environment, and environmentally-friendliness and sustainability are emphasized. In spite of that railroad has high energy efficiency and environmental-friendliness to advantage traditionally, there is still transport division rate of railroad in declining tendency as investment policy that is concentrated on road and insufficiency of social realization about environmental problem. The construction of environment-friendly transport system and the reasonable role sharing between modes of transportation are important. Transportation policy of Korea is presented through plans to constructs efficiently and manages national transportation system. In this study, examine development process of national railroad logistics plan with logistics environment change, and proposes the following ways to development of railroad logistics policy.

Due to the reduction of greenhouse gases and a sharp increase in the energy prices the world over, there is a growing interest in the railroad transport. In particular, in the case of containers which are the major item of railroad transport, a need for the switchover from the road transport to the railroad transport is being suggested, however, it is understood that the extent of the switchover occurring is only marginal. There exist many causes that account for the marginal extent of the switchover to the railroad transport. Some of them have to be dealt with at the policy level and efforts are needed to make it more efficient to use the railroad than other means of transport by improving railroad logistics facilities. Thus, the present study seeks to examine the possible measures for improving the railroad logistics facilities to promote the railroad transport.

As the demand for logistics services increases rapidly in modern society, the existing freight delivery system through road transportation is caused various problems such as traffic congestion and greenhouse gas emissions. To solve that, the development of an 'underground logistics tunnel-based cargo transportation system' is currently being considered in Korea. In order to build a new concept stable and safe logistics system, derive system design requirements and functional specifications, and reflect them at the development of target system. In this study, to make foundation for development of an "underground logistics tunnel-based cargo transportation system," define system components through analysis from a hierarchical perspective, and the functions of each component were analyzed and defined. We identified what interfaces the components have at each stage of the operating process. Lastly, we defined a detailed operation scenario based on the previously derived results, deriving target system functional requirements.

Present Prices have reduced to $100 per barrel, but international oil prices caused big damage to local logistics industry due to rise in International oil prices and, in august 2008 oil prices reached up to 146 US. Depending on oil prices, the domestic logistic industry should develop a strategy by innovative management of purchase of supply for manufacturing industry and efficient supply and demand of resources which is believed to be more important. Accordingly, we want to analyze railroad logistics' present condition and effect on railroad industry that can expect affirmative development by oil-price rise and by developing strategies for efficient railroad logistics.

물류공동화는 운송부분에서의 공동화로 시작되어 최근에는 배송과 보관 등 물류의 전 분야에서 도입되고 있으며, 물류공동화에 의한 효율성은 여러 형태로 입증되고 있어 많은 부분에서 물류공동화를 적극적으로 도입하고 있다. 그러나 현재 추진 또는 시행되고 있는 물류공동화는 도로를 중심으로 공동간선수송, 공동배송, 공동보관 등이 시행되고 있는 실정이다. 또한 국가주도의 물류단지에서의 공동화와 민간부분에서의 공동화가 활발히 시행되고 있는 실정이다. 이에 본 논문에서는 환경 친화적인 수송수단으로 부각되고 있는 철도부분에서의 물류공동화 도입방안에 대하여 검토하였다. 기존 철도분야에서의 물류공동화 사례 분석 등을 시행하고, 향후 철도에서 물류공동화 도입이 가능한 분야들 중 간선수송에서의 공동화뿐만 아니라 철도역에서의 보관, 배송부문에서의 물류공동화 도입 방안 등에 대하여 검토를 시행하고 도입방안을 제시하였다.

Recently, the Korean government has been making efforts to achieve 'creative economy' based on science and technology. As part of these efforts, it has been promoted specific policies for innovation and performance enhancement of national R&D projects. They contains commercialization of research outcomes, technology transfer, technology based startup and support small and medium-sized businesses. The railroad transportation industry is a representative in the field of SOC and has own characteristics different from other industry areas. Especially, industry and market of railroad transportation are directly related to planning and implementation of government SOC policies. So in order to promoting commercialization of railroad transportation projects, it is very important to ensure consistency between government policies and R&D projects. In this paper, we investigate barriers of successful commercialization with typical researchers in the area of railroad transportation, and suggest problems and improvements of policy-based commercialization by giving specific examples.

In recent years, if we order food by easily accessing the online market with our smartphone, we can receive the product in a fresh state at dawn the next day. Cold chain is an industry that can create high added value because it has both the characteristics of general logistics and sensitivity to temperature. Based on the electrical specifications derived from the reefer container capacity requirement investigation, we proved that power supply to up to 33 reefer containers can be made by using three additional auxiliary power supplies which are applied for freight trains in Korea. In this paper, we conducted a research on a design of power supply system for freight train reefer container based on simulation as a basic research necessary for low-temperature distribution and cold chain construction based on the reefer container railroad. Consequently, the simulation was conducted using the three-phase inverter diagram in PSIM and the SVPWM (3-harmonic injection method) control technique, and it was verified that the required power voltage was satisfied with 622V_dc, which is lower than the input voltage of general SPWM of 718V_dc. The details of this paper could be used as a foundational study for constructing cold chains based on a reefer container dedicated to freight trains in the future.
