  • 국내 원자력발전소의 사용후핵연료 저장용량의 포화가 10년 이내에 예상되고 있으며, 소외중간저장방식을 관리 방안으로서 선정할 경우, 상당한 양의 사용후핵연료 운반이 해상 혹은 육로를 통해 매년 이루어져야만 한다. 본 논문에서는 4곳의 원자력발전소부지에 분산 저장되어 있는 사용후핵연료를 해안에 위치한 가상의 중간저장시설과 영구처분시설을 대상으로 사용후핵연료 운반물량을 효과적으로 분석할 수 있는 체계를 구축하였다. 각 발전소 부지, 중간저장시설, 영구처분시설의 저장고를 중심으로 사용후핵연료 물질 수지식을 세우고, 이에 대한 해를 VISUAL BASIC으로 구하여 운반 물량 분석이 용이하게 수행할 수 있는 컴퓨터 프로그램(CASK)을 개발하였다. 개발된 물량 분석 프로그램을 활용하여 4개 원자력 발전소 부지로부터 사용후핵연료 운반 물량을 분석하고, 운반물량 파라미터 분석을 통하여 본 프로그램의 활용도를 보였다. 개발된 사용후핵연료 운반 물량 분석 체계는 향후 운반비용 분석에도 유용하게 활용될 것이다.

  • Imported and exported agricultural products are facing a very difficult time due to the rising distribution costs spurred by the increasing labor and oil prices. High empty transfer rates, which take place on a return route after the regular transportation of imported and exported agricultural products, are especially a major cause of the rising distribution costs. In an effort to overcome those limitations, this study set out to examine the transportation stages connecting harbor warehouses, processing plants, and central distribution centers on the circulation route of such imported grains as wheat, barley, corn, and soybean and the transportation route from the warehouses devoted to exported agricultural products to harbors for such exported agricultural products as apple, pear, and persimmon in order to develop a model on the creation of a compound logistics complex for processing plants and transshipment of imported and exported agricultural products. The study also promoted the logistic rationalization of imported and exported agricultural products by creating a compound logistics complex that would combine processing plants for imported agricultural products and transshipment functions for exported agricultural products.

  • Purpose : The purpose of this study is to find that Factors in the practical application of LISMB(Logistics Information System Practice Based) on S.P(Smartphone)' Characters. and take in the whole situation of LISMB on S.P' Characters by this research and it is clear from the findings that LISMB on S.P' Characters situations and distinctiveness. Research design, data, methodology : Research model and hypotheses have been developed based on literature review and working-level interview The collected data were analysed with structural equation modeling, examining the hypothesized relationships and mediating effect. Result : The results of research are as follows, First, LISMB on S.P' Characters has a positive effect on a precariousness of operation management. but That has no effect on a precariousness of general management. Second, Consign management and User non-cooperation has a mediating effect on relationships between LISMB on S.P' Characters and general management. Third, Old version system, User non-cooperation and Unskilled in equipment new system has a partly mediating effect on relationships between LISMB on S.P' Characters and operation management. Conclusion : Smart-phon Prevalence rates keeps increasing. Nevertheless, LISMB on S.P' Characters may no be used in Container transportation market. This problem are being blamed for hampering corporate activities and harbor logistics industry development. so we need new way to solve that problem.

  • Recently, securing stable supply of fresh food is deemed as one of the important tasks. Accordingly, now the presence of cold chain along with the needs of a comfortable and healthy life is growing as the online market expands and the contactless industry grows, however, cold chain is being studied only in the aspect of ground and sea transportation. And, due to global warming and strengthening global environmental regulations, we believe that it is necessary to convert the existing road-centered logistics system into a railway-centered logistics system, a low-carbon transportation means. Therefore, in this paper we calculated the maximum energy required by the reefer container as a basic research necessary for constructing the low temperature distribution and cold chain based on the reefer container railway, and conducted a study on methods of supplying the reefer container power utilizing 1. tramline, 2. battery, 3. generator. The results of this paper can be utilized as a foundational study for building a cold chain based on a reefer container dedicated to freight trains in the future.

  • As the distribution of vehicles and logistics increases due to the development of human civilization and the increase in population, various roads play an important role in domestic traffic and transportation. However, the recent emergence of large cities and new cities is causing traffic problems, and the increase in roads is inevitable for the smooth distribution of vehicles and logistics. In Korea, mountainous regions occupy 70% of the country, so tunnels are used to open roads. Without this, it is difficult to open the road. Currently, there are 3,720tunnels (as of December 31, 2023) installed on high-speed national highways, general national highways, and local roads nationwide, with a length of 2.499 and increasing every year. Accordingly, fire accidents in tunnels will also increase, and due to the nature of tunnel fire accidents, there is a high probability that they will escalate into large-scale disasters, resulting in casualties and property damage, as well as significant social losses due to the disruption of logistics transportation, etc. As the possibility of potential hazards is increasing, the purpose of this study is to build a safe and efficient tunnel system by optimizing maintenance and management for fire and disaster accidents in tunnels.

  • Recently, according to changes of global logistics environment, various issues have been presenting. These issues are including the pursuit of low cost-high added value, the realization of sustainable logistics system, the protection of environment, and the development of ubiquitous techniques. To cope with these environment changes and improve the national logistics system, the government have carried out various logistics policies and pushed ahead development of national logistics information network. But still, from a view-point of national logistics, there are several inefficient elements such as information inconnection and code/data unstandardization. In this paper, the survey result of domestic inland-logistics information system status will be presented and the future developments will be presented for the efficient national logistics.

  • First we provide an overview of how virtual enterprise works, including the lifecycle of a virtual enterprise, expected benefits from a virtual enterprise, and various types of collaborative networks. Next we focus on a problem encountered in the port logistics industry and suggest that implementation of a virtual enterprise can be a good solution to the problem. Then we suggest a prototype of the virtual enterprise in the port logistics industry and a freight transportation process as a business process in the prototype. And then we introduce major functions of the business process management system (BPMS) which, in general, can be regarded as a tool to create the virtual enterprise. Finally by adopting a specific BPMS, we illustrate how to design and implement the freight transportation process in the prototype.

  • "물류산업"은 장래 우리나라의 새로운 성장산업의 하나로 인식되고 있다. 그간 우리나라는 중국화물의 환적거점으로 기능을 하였으나, 최근 중국 자체항만의 성장으로 대형선단이 중국으로 이동하고 있다. 결과적으로 한국의 물류중심의 입지가 위기를 맞고 있다. 이러한 시점에서 물류혁신과 국제경쟁력 강화를 위해 새로운 전략이 필요하게 되었고, 본 연구에서는 "부가가치물류클러스터"를 새로운 전략으로 제안하고 있다. 특히 본 연구는 한국의 입지적 산업적 장점을 극대화할 수 있는 한국형 부가가치물류클러스터를 제안하고 있다. 추가적으로 한국 항만이 동북아 물류거점으로 성장할 수 있도록 한국형 부가가치물류클러스터 모형이 제안되었다. 클러스터 구성요소, 물류산업과 타 산업 간의 연관성 분석과 같은 다양한 분석과정이 한국형 부가가치물류클러스터 모형을 개발하기 위해 단계별로 시행되었다. 또한 한국형 부가가치물류클러스터 모형을 물동량 감소로 최근 위기를 맞고 있는 광양항에 적용하였다.

  • This paper shows the direction in which logistics modellers should make their effort by examining the gap between desirable characteristics which logistics decision models should possess and deficiencies from which existing models suffer. For this purpose, we(1) categorized logistics models into facility planning, inventory management and transportation/delivery planning models, (2) carried out a wide survey of theoretical and industry models within each category and (3) assessed recent development of integrated logistics models.
