운송 서비스산업에 대한 지속적인 규제완화는 운송 기업의 진입 및 퇴출을 자유롭게 하였고, 외국 기업의 국내에서의 영업 활동이 가능하게 했을 뿐 아니라, 업종간 분류를 무의미하게 하여 운송기업은 전방위 경쟁을 피할 수 없게 되었다. 이러한 경쟁 환경하에서 운송 기업의 효율적인 운영은 국가 물류비 절감 측면에서, 그리고 해당 기업의 사활 측면에서 매우 중요한 의미를 갖는다. 소화물 일관 수송은 택배 또는 특송이라 불리우는 운송 서비스업의 일종으로, 화주 한명의 화물량이 차량 한 대 분량에 못 미치고, 고객이 원하는 출발지에서 목적지까지 운반해주는 특성을 가지고 있다. 소화물 일괄 수송은 지역을 순화하면서 화물을 접수하여 인근 터미널까지 운반하는 수집과정, 터미널과 터미널을 연결하는간선수송 과정, 터미널에서 최종 목적지까지 운반하는 배달과정을 거쳐 이루어진다. 본 연구를 통하여 터미널과 터미널을 연결하는 간선 수송과정에서 발생하는 비용을 줄이는 화물운송경로를 찾아주는 네트웍 최적화 모형이 개발되었으며, 이를 실제 업무에 적용하여 화물운송 경로를 조정함으로써 적재율 20%이상 개선, 운송비용 10%이상 절감이 가능함을 확인하였다.

The term 'green' has become an important way of survival for the construction industry in 21th century in accordance with the emergence of the environmental crisis due to the climatic change. Especially the policy of carbon taxation, planed to be introduced from 2012, is expected to be a considerable burden to the construction industry which has abundant carbon emission during the resource transportation due to the complexity of resources and local distribution of the construction sites. In this regard, this study shows an optimizing strategy for delivery frequency, which downsizes the net distribution costs based on the assumption that, despite of its other advantagements, the frequent small lot mode of JIT delivery would take negative effects due to the increase of costs of transportation and carbon emission once the carbon taxation policy carried out. To simulate the efficiency of the management strategies, the System Dynamics modeling has been used. The results show that the frequent small lot transportation strategy is now always efficient method to these changes, and that the frequency of transportation should be re-determinated according to the extent of the imposition of carbon tax. This study provides the conceptual frame for an efficient management of transportation system of the construction industry, showing necessity of change of the resource transportation systems through analysing JIT deliver system in accordance with the global changes in environmental economy.

Mongolia as a land-locked country, has tried to diversify its foreign trade with European and Asian countries. Recently continual price rise of mineral resources also helps Mongolia have chances to gain her trading partners. Nevertheless, regulations and barriers to exports of Mongolian mineral resources in China and Russia, which are transit countries, are complex and complicated in border crossing and transshipment procedures for transit transport. This paper discusses problems and barriers to economic and efficient logistics systems and transit transport of Mongolian mineral resources, and addresses a proposal of international intermodal transport corridors for improving transit transport, and suggests international cooperation, by applying transit rights of land-locked country. Specifically, it is necessary for Mongolia to search for other international intermodal corridors besides the corridor through the port of Tianjin. It is needed to build an international organization for discussion of affirmation of logistics equipments and improvement of transit procedure in border crossing, and to raise financial feasibility in building a new intermodal corridor.

Today, the logistics industry has played a critical role in national economy activities. The low cost and high efficiency of the logistics industry are meaningful in the improvement of national competitiveness and the logistics industry. However, efficiency of logistics is lower than that of the United States and Japan since most quantities are processed in road transportation in Korea. With regard to this, existing studies expected a saving of social and environmental costs due to a decrease of road transportation as well as improvement of logistics productivity due to bulk transportation through activation of rail and costal transport. For the expectation, the existing multimodal transport systems should be improved first. Therefore it aimed to develop scenario-based simulation models of multimodal transport systems for decision makers in charge of improvement in the logistics area. For model development, this study utilized Thinking Process and System Dynamics(TP-SD) methodology.

Along with the increase in global volume of goods, logistics companies are trying to reduce costs by increasing the size of ships carrying cargo, increasing the efficiency of quantitative equipment at ports, and unmanned electric vehicles on land. Korean naval ports are also facing the same situation as the global trend. In the past, small and medium-sized ships such as FF, PCC, and beheaded eagles are being retired for their longevity, and their positions are being replaced by large ships such as KDX, FFG, and LST-II. In particular, large ships such as Dokdo and the next light aircraft carriers are also being prepared. Unlike general merchant ships, naval ships require periodic inspections and preventive maintenance, so repair piers such as maintenance depots are in operation. The naval maintenance depot mainly uses trailers, trucks, and truck-type cranes to carry out loading and unloading of heavy ships, and the application or development of automation and unmanned equipment performed by the private sector is inadequate, and self-improvement cases are also very weak. This study aims to improve the efficiency of the military logistics system through research on the logistics system such as transport, storage and unloading of heavy goods and maintenance products of naval ships.
