본 연구는 물류서비스 품질과 파트너십의 장기지향성을 높이는데 수송의 역할이 중요하게 작용하고 있음을 검증하고 있다. 문헌고찰을 통해 도출한 수송의 역할 차원은 정보공유, 위험과 보상의 공유, 성과향상 노력 및 장기결속이다. 분석견과 이러한 수송의 역할 차원들은 물류서비스 품질 향상에 기영하고 있으며 유연성, 적시성, 상호작용성의 물류서비스 품질의 향상으로 인해 수송업자와의 파트너십을 장기적으로 유지하고자 하는 장기지향성이 높아지는 것으로 나타났다. 공급사슬 내의 수송업자의 역할에 대한 심층적인 분석결과를 통해 볼 때, 향후 공급사슬 내의 파트너십에서 실질적인 수송의 기능을 적으로 고려해야 한다.

The integration of nanoparticles into various industries has spurred interest in understanding their impact on logistics and transportation systems. In this study, we investigate the effect of nanoparticles on the economic aspects of railway logistics transport using a mathematical model. By incorporating factors such as transportation costs, time efficiency, and environmental considerations, we aim to assess the overall economic feasibility of integrating nanoparticles into railway logistics operations. Through mathematical modeling and analysis, we explore how the introduction of nanoparticles affects cost-benefit analyses, resource allocation, and decision-making processes within railway logistics. Our findings provide valuable insights into the economic implications of nanoparticle integration in railway transport, offering potential strategies for optimizing logistics operations and enhancing overall efficiency and sustainability.

본 연구의 목적은 기업과 소비자간 전자상거래에서 물류운송체계의 물류비용을 상품운송 유형에 따라 분석하는 것이다. 먼저 물류운송체계를 3가지 유형 즉, 공급업체에서 소비자에게 직송하는 방법(유형 I), 자가물류업체를 통해 각 권역에 운송센타를 두어 운송하는 방법(유형 II), 3자 물류업체에게 운송에 관한 모든 일체를 위임하는 방법(유형 III)으로 분류하고 각 유형의 물류비 항목을 운송비, 보관비, 물류정보비로 구성하였다. 전자상거래에서의 물류는 다품종 소량 다빈도 특성을 가지고 있고, 주문특성 및 상황에 따라 소요물류비용이 변한다. 그러므로 본 연구에서는 대상권역의 주문에 대한 1일 주문건수 운송거리, 운송량, 그리고 1일 배정화물트럭대수에 따라 변하는 물류비용함수를 도출하였고, 가상네트웍을 구성하여 시뮬레이션 함으로서 각 운송유형의 주문특성에 따른 물류비용의 변화를 분석하였다. 하지만, 본 연구는 공급업체의 물류인프라와 운송서비스 시간에 대한 고려를 하지 않았기 때문에 현실에 적용하기에 한계가 있다. 만일 이에 대한 연구가 보충된다면 전자상거래에서 일정 단위기간 동안 상품운송에 소요되는 물류비를 좀더 정확히 추정하여 전자상거래에서의 효율적인 화물운송방안을 제시할 수 있을 것이다. 본 연구의 결과로 전자상거래에서의 1일 주문발생 빈도와 공급상품의 중량. 그리고 운송거리에 따라 변하는 물류비용을 추정할 수 있다.

Transportation in the logistics, many business organizations are engaged in monitoring and tracking the vehicles in order to improve logistics services, reduce expenses and secure security in cargo transportation. It is saving time and money by tracking and monitoring vehicles which transport cargo in supply chain of logistics. Therefore the main issue of delivery flow is to improve services, and ensure the safety in transportation system. This article suggests the tracking and monitoring model to keep safety transports on ICT network. It focuses on precise delivery control by monitoring and tracking vehicles to save time and costs. The status of product movement is analyzed for proper decision making. The vehicle embedded with RFID is automatically tracked in the movement process by tracking and monitoring model. The main role keeps safety tracking to reduce costs and to deliver products at proper time and location.

Uniform and integrated college desks and chairs have low efficiency of loading for transportation and delivery and low efficiency of storage for warehousing due to their simple uniform physical properties, thus increasing logistics costs for companies and decreasing their competitiveness. In an effort to overcome the limitations of previous studies, this study analyzed the stages of logistics for desks and chairs in college lecture rooms via the transportation route including the factory warehouses and local warehouses and via the delivery route from local warehouses by the region to the orderers including college lecture rooms. The study developed a model for the rationalization of corporate logistics by making a variable folding desk and chair capable of distance adjustment according to height to replace the uniform and integrated college desks and chairs in lecture rooms. A model was developed between the old uniform and integrated college desks and chairs and the new variable folding desks and chairs for three scenarios of cost development including product storage costs, transportation costs from the specialized factory warehouses to the local warehouses by the region, and delivery costs from the local warehouses to college lecture rooms as the orderer. For the generalization of the model, it was applied to each of the 90%, 95%, and 99% service levels.

This paper develops an analytic model for minimizing the cost of distributing items by truck from one supplier to many customers under Milk run logistics strategy. The model derives formulas for not only inventory and transportation costs but also costs associated with carbon emission trading scheme. In addition, monetary investment for reducing carbon emissions is considered. We analyze how to determine optimal shipment size and carbon emission reduction investment. The purpose of this work is to evaluate the effects of carbon emission trading scheme on the Milk run logistics strategy in terms of how much to reduce carbon emissions and/or inventory and transportation costs. We analytically show that it is possible to reduce carbon emissions while reducing inventory and transportation costs by introducing cap-and-trade carbon emission trading scheme under certain conditions.

Hai Phong is the important transportation hub of the northern Vietnam with many advantages. Hai Phong can connect with orthers provinces by road, railway, airport, seaport system and inland waterway. So far, Hai Phong is develop so fast However, Hai Phong's logistics services are still low level and less competitive. The human resources are lacking of experiences and also low quality, the logistics enterprises are small, low capital and they can not compete with foreign companies. Further more, the infrastructure are invested but there are still have some problems inside. This paper has assessed and systemized the situation of development of Hai phong.

This paper proposes an algorithm which reduces transportation cost while goods are delivered in time in a logistics system. The logistics system assumed in this paper is the system in which multiple cars moves various goods from spatially distributed warehouses to stores. For reducing transportation cost, the car assignment algorithm which allocates goods to minimal cars employs the BF method; routing of each car is modelled as the TSP and is solved by using the genetic algorithm. For evaluating the proposed algorithm, the logistics system is modelled and simulated by using the DEVS formalism. The DEVS formalism specifies discrete event systems in a hierarchical, modular manner. During simulation, each car is modelled as a message and traverses warehouse and stores. When a car arrives at a warehouse or a store, predetermined amount of goods are loaded or unloaded. The arrival time and departure time of cars are analyzed and eventually whether goods are delivered in the desired time bound is verified.

교통, 정보통신 등 기술의 발전은 물자의 흐름을 가속시켜왔으며, 지역적 범위의 물류가 국가적 범위의 물류로 확장됨에 따라 국가 물류정책에 대한 중요성은 증가하고 있다. 국내 물류시장의 급격한 성장으로 인한 물류시설의 공급부족, 물류시설의 비효율적 운영, 유통구조의 복잡성과 같은 문제를 해결하기 위해 거점물류시설을 건설하여 효율화를 도모하였으나 저조한 운영실적으로 어려움을 겪고 있다. 거점물류시설에 대하여 활성화 방안에 관해서는 많은 연구가 이루어지고 있으나 사설 물류업체와의 기능중첩에 초점을 맞춘 원인분석은 이루어지지 않고 있다. 이에 본 연구에서는 영남내륙화물기지의 기능상실에 따른 인근 물류시설과의 기능중첩과 연계체계의 불합리성에 대하여 분석 하였다. 국내 화물수송의 대부분인 육로운송에서 기능 중첩에 따른 거점물류단지 미 이용에 대한 원인을 제시함으로써 향후 국가단위 물류 인프라 정책의 측면에서 의미를 찾을 수 있을 것으로 판단된다.

In the end of 2007, Korea Government promulgated the Rule of 'Basic Act of Logistics Policy' for improving international logistics forwarding business. The goals of these rules are to achieve the development of our nation's economics for providing the security and efficiency of logistics system and enforced competition of logistics enterprises. This is established the basic principles of the legal basis for expanding into the Logistics Hub Center of North-east Asia. However In May 1999 new licensing requirements for ocean freight forwarders and NVOCCs operating in the USA were established by the US Federal Maritime Commission(FMC). Due to these regulations, each ocean transportation service provider in the USA acting as ocean freight forwarder, NVOCCs, or NVOCC agent must obtain a license to operate as Ocean Transportation Intermediary(OTI) before it begins operations. Only licensed OTIs may act as US transportation agents or receiving agents of other NVOCCs, on both US exports and imports. In this context, I think this study will be contributes for the development of korean freight forwarding system by analysis and comparing with between the Rule of the Basic Act of Logistics Policy of Korea and OTI freight forwarder & NVOCCs of USA.
