최근 '정보기반 물류망'에서 'u-기반 물류망'으로 발전해 가고 있는 시점에서 'u-기반 물류망'을 위해 다양한 기반 기술들이 요구되고 있다. 본 논문에서는 물류 관리 시스템 구축을 위해 GPS 기반의 물류위치 추적 기법과 센서 Tag를 이용한 물류 배송 효율화 시스템을 설계하고 구현한다. 또한, 물류 배송 효율화를 위해 센서 Tag 네트워크 시스템을 제안하며, 이 센서 Tag 네트워크를 기반으로 수집된 센싱 정보를 이용하여 물류의 위치와 상태, 이동경로 등을 파악함으로서 물류의 배송이 효율적으로 이루어 질 수 있도록 지원한다. 제안된 시스템은 관리자에 의해 유지 보수 될 수 있는 제어 가능한 센서 Tag 네트워크(Controlled Network Layer)와 무제어 이동 센서 Tag 네트워크(Uncontrolled Moving Objects Layer)로 구분하여, 일반적인 센서 네트워크 시스템의 배터리 문제를 보완하고자 한다.

The construction Supply Chain Management(SCM) plays a critical role to proceed construction projects successfully. It is necessary to develop a system to support better communication among various actors and to supply construction materials in the right place on time with unstable situations on site according to the planned construction schedule for effective Supply Chain Management. Therefore, the objective of this study is to propose an automated and intelligent process that can be used to utilize ubiquitous technologies in construction supply chain management. This process consists of various equipments that can collect, store, calculate and communicate data among themselves. This study deals with a conceptual idea in order to improve process and equipment in the supply chain management process.

Recently, there have been many studies on RFID-based SCM. Yet, studies of synchronizing errors caused by tracking logistics information in supply chain, and activating & monitoring RFID infra is still insufficient. Also, there is no case of developing the intelligent SCM system enabling total monitoring and controlling RFID Infra by applying these technologies. Logistics information synchronization based Smart SCM model is intelligent supply chain service model to monitor the status of the RFID equipments in supply chain and the synchronization of the logistics process in each logistics point through one integrated view, as well as to react instantly by providing the information to help the various decision makings, when the emergency occurs. By adopting global logistics standard, RFID related standard specification, EPCIS standard, and SSI middleware platform, this model provides the domestic standard specification.

Countries around the world, including the U.S. are actively researching to commercialize the logistics services using drones. In Korea, telecommunications companies as well as logistics companies are researching and developing the logistics services using drones. However, there's an environmental difference for last-mile delivery between the U.S. and Korea. In Korea, more than 77% of the population lives in apartments and the population density is the 4th highest in the world. Accordingly, in terms of the logistics services using drones, it is necessary to research it with the Korean suitable environment. In this paper, a precision positioning method of drone last-mile delivery in urban areas using short-range wireless communication and barometer is proposed. The experiment results show that the proposed method can detect a window within 2.5 meters. It is expected that the proposed method will help improve the logistics services using drones in urban areas.

Recently, Logistics industry has emerged a new u-logistics paradigm combines USN / RFID technology. In this paper offers a vehicle history Web-based logistics management system based on the u-logistics paradigm. The design of this system is considered all events processes as a form of recycling and entire system is to modeling based UML of object oriented. Also It was undergone some process to make sure by logistics vehicles identified that RFID based was identified vehicle logistics. To identify logistics vehicle based RFID, identified the logistics vehicles is a process that will determine. The implementation method designed the interface based web which uses in the manager to C/S methods, consideration of the mobility of the system user implements the user GUI based PDA. As well as, In this paper was separated customer, manufacturer, distributor, administrator, drivers, respectively and focuses to raise a system reusability which is implementation by separately for each feature.

The third party logistics(3PL) is generally understood as the logistics activities providing a comprehensive logistics services, all or partly outsourced by the customers on a larger term contract basis, ranging from making logistics strategies to implementing information technology services. A lot of companies in advanced countries such as the U.S.A. or some of the European countries have actively outsourced to logistics service providers in efforts to increase the efficiencies in logistics operation rather than doing themselves. In light of these environments, outsourcing to third parties has become a strategic issue demanding greater attention in corporate boardrooms. First, after deciding their logistics outsourcing, the companies have to set up their aims of 3PL through the development of logistical strategies. Second, the companies must decide service provider that fits to their business environment and conditions. As it is reported that 3PL services will bring a high rate of return and its potential will be more signigicant, providers and users of 3PL services and government ministry should prepare the way of improvement of logistics institution and plan to activate 3PL services to reach the advanced foreign countries level.

Many studies are being applied for various parts of USN (Ubiquitous Sensor Network) technology. The world's large retail stores and warehouses that apply logistic management are also studied. With this, USN technology is increasing in its utilization. However, to handle and process real-time data will never be never easy if these huge warehouses are using too many sensors, and real-time data correction is almost impossible. Software implementation and high-speed hardware are insufficient to solve these complex problems. To solve this problem, a key solution is to implement high-speed software. Hence, this paper suggests a USN logistics management system that applies pipelining techniques for efficiency in real-time data correction and reduces errors of generated values.

The rapid growth of e-commerce market and changes in distribution channels and consumption patterns have brought about the continuous growth of the domestic parcel service market. To cope with the growth and environmental changes of the parcel service market, parcel companies have made efforts to improve logistics process and construct an information system for customer satisfaction. Since they have focused on a high quality parcel service through a variety of information technology rather than price competition, the importance of logistics information technology has been greatly perceived. Accordingly, this study examined that how information technology and information system quality of parcel companies was perceived by customers and how it influenced parcel service use and satisfaction. To achieve this purpose, this study developed a valid and reliable measurement instrument for logistics information system quality and customer satisfaction based on literature reviews. Then empirical research was made through a questionnaire survey. As a result, six determinants of logistics information system quality were derived: economy, SMS information, tracking web-site information, stability, speed, and accuracy. All factors but economy were found to have positive effects on customer satisfaction in parcel service. Finally, the theoretical and practical implications of the findings were also discussed.

우리나라에서 무역이 차지하는 비중이 적지 않다는 점은 누구나가 주지하고 있는 사실이다. 이와 관련하여 관련 당사자들은 이러한 무역을 통한 경제성장을 위하여 치열한 노력을 경주하고 있으나, 현실적으로 저임금 노동력을 바탕으로 한 개도국 제품과 고도의 기술력을 바탕으로 하고 있는 선진 제국의 틈바구니에서 어려운 경쟁을 벌이고 있다. 이를 물류의 측면에서 살펴 본다면 제반 경쟁국에 비해 관련 물류비 역시 높은 실정으로서 전자무역의 환경하에서 이러한 물류업체들의 현황은 어느 정도 수준이며, 이와 관련된 제반 문제점은 무엇인가를 규명하고 그 대용방안을 모색하고져 한다.
