This study deals with a strategic decision making in two level supply chain network design. This study presents more realistic mathematical model than the previous studies by considering simultaneous location of plants and distribution centers, determination of capacity level for both plants and distribution centers, and upper limit condition for numbers of locating plants and distribution centers. This paper tries to help the strategic decision making for two level supply chain network design. For this purpose, three different sized numerical examples are generated and optimal solutions are obtained by applying Excel Solver program. And sensitivity analysis is performed for the biggest sized example problem, which has 10 potential plants, 20 potential distribution centers, and 200 customer zones. After the plants being located are fixed, optimal minimum costs are obtained and compared for each of 7 different numbers of distribution centers to be located. As the number of distribution centers increases, changes in inbound transportation cost and outbound transportation cost can be derived. In case of considering cost as well as customer satisfaction level for two level supply chain network design, the analysis of this changes may help more sophisticated decision making.

The EPCglobal Network is a system which provides the information of items to suppliers, consumers, and customers by granting identification numbers on the goods based on the technologies of EPC(Electronic Product Code) and RFID(Radio Frequency Identification), and connecting the space to store those information by network. The EPCglobal architecture framework is also a service consolidating supply and process chain by using EPC for the common goal of business corporations. In the national level, it is necessary to define standard vocabularies for each location and logistics business process for RFID environment using the pre-constructed logistics information infrastructure. Therefore, we define the standard vocabularies and partially user vocabularies for international logistics on EPCglobal network architecture. Finally, we believe that our vocabularies contribute to describing the events fur the EPCglobal network architecture and actually providing usable platform via the XML implementation.

The logistics information system has been recently attracting a great deal of attention for its importance in the national economy. It should be noted, however, that the degree of the system utilization differs by the capabilities of the logistics firms such as logistics management skills, robustness of the organization, technical sophistication, and administrative abilities. A survey was conducted in the Busan and Kyungnam area for 174 companies in the logistics and manufacturing industry. The results of this study can be summarized as follows : First, the degree of utilization of the logistics information system varies depending upon business-type details. Secondly, utilization of the logistics information system is equally important for both manufacturing and logistics companies. Thirdly, it was found that the executives of the companies with logistics management skills can play a key role in utilizing the logistics information system. Finally, the degree of utilization has positive relationships with the logistics performance as the companies benefit from the system not just for saving costs, but more importantly for providing higher-quality services for their customers.

Companies are facing challenges to have high competitiveness because of continuous oil price rising and CO2 emissions regulations. Thus, companies are trying hard to construct effective logistics and operation system to achieve high customer service quality and saving cost. Also the ec-friendly idustrial complex is needed. Busan is in process to construct GILC(Global Industry Logistics City) in west Busan province to achieve high competitiveness and support lack of industrial complex. To construct this kind of logistics industrial complex, it needs logistics system through proper policy and freight transportation co-operation. Especially, efficient management through logistics hierarchy construction in industrial complex is very important for low cost and eco-friendly point of view. Therefore, this paper aims to analyze logistics system and suggest operation model to present logistics complex construction base data.

텔레매틱스의 한 분야를 차지하고 있는 LBS(지리정보서비스)는 도시 구석구석이 유.무선 네트워크로 연결돼 편리하고 안전한 환경을 조성하는 'U-시티' 시대를 구성할 수 있을 뿐아니라 생활의 편리함을 안겨준다는 이유에서 차세대 컨텐츠로 각광받고 있다. 모바일 분야의 경우, 그 동안 게임 위주의 오락 이 시장을 이끌어왔지만 향후에는 위치정보가 주도할 것으로 평가되고 있다.

IoT(Internet of Things) has become a major issue as new type of convergence technology, expending existing of USNs(Ubiquitous Sensor Networks), NFC(Near Field Communication), and M2M(Machine to Machine). The IoT technology defines as a networking for things, which can establish intelligent links collaboratively for sensing networking and processing between each other without human intervention. The purpose of this study is to investigate to forecast the future distribution changes and orientation of contribution of distribution industry on IoT and to provide the implication of distribution changes. To become a global market leader, IoT requires much more development of core technology of IoT for distribution industry, new service creation and try to use a market-based demand side strategy to create markets. So, to become a global leader in distribution industry, this study results show that first of all establishment of standardization of IoT, privacy safeguards, security issues, stability and value were more important than others. The research findings suggest that the development goals of IoT should strive to boost the creation of a global leader in distribution industry and convenience to consider consumers' demands as the most important thing.

RFID 시스템은 물품 등 관리할 사물에 태그를 부착하고 전파를 이용하여 사물의 정보(Identification) 및 주변 환경정보를 인식하여 각 사물의 정보를 수집, 저장, 가공 및 추적함으로써 사물에 대한 측위, 원격처리$\cdot$관리 및 사물간 정보교환 등 다양한 서비스를 제공하며, 칩, 태그, 리더, 미들웨어 및 응용서비스 플랫폼으로 구성된다. 이러한 RFID 기술은 반도체 기술의 지속적인 발전에 의한 컴퓨팅 능력의 급성장과 통신망 인프라의 융합화를 기반으로 이제까지의 사람 중심(anyone) 정보화에서 사물을 중심(anything)으로 정보화의 지평을 확대시킬 수 있는 핵심기술로서 부각되고 있으며, 10m 이내의 사물 정보화를 위한 u-센서(유비쿼터스 센서) 네트워크로 발전될 전망이다. 또한 현재 완료단계인 ISO/IEC 국제 표준제정이 완성되면 초기의 물류$\cdot$유통 분야에서 전 산업분야로 확대되어 사용될 것이다.

최근 이동체 관리 기술 중 물류 및 차량 관리, 응급 서비스 등 실세계에 많이 응용되는 도로 네트워크(도로, 철도 선로 등) 기반 이동체 관리에 대해 많은 연구가 진행되었다. 도로 네트워크를 따라 움직이는 이동체는 이동 영역이 한정되어 있기 때문에, 이러한 특징을 반영한 현재 위치 색인 및 과거 위치 색인이 개발되었다. 그러나 실세계 응용에서는 이동체의 과거 및 현재 위치를 모두 필요로 하는 경우가 많아서 두개의 색인을 별도로 유지하여야 하며, 이는 비효율적인 노드탐색 비용을 유발하고 색인 사이에 공통된 부분이 존재함에도 불구하고 중복된 유지를 해야 한다는 문제점이 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 도로 네트워크 기반 이동체의 통합 색인을 제안한다 제안 색인은 도로 네트워크 기반 이동체의 현재 위치 색인 및 과거 위치 색인의 공통된 부분인 도로 네트워크를 저장.관리하는 부분을 공유하여 색인 유지비용을 줄이며, 현재 및 과거 위치 질의에 대해 불필요한 노드 탐색 비용도 감소시킨다. 또한 과거 및 현재 위치 색인을 통합함으로써 효율적으로 과거 위치 정보를 생성.저장하는 것이 가능해진다.

While major alliance container carriers in the post-corona era are enjoying the largest boom in history with their fleet reduction strategy, shippers companies are in a state of deteriorating import and export price competitiveness due to increased logistics costs, and forwarders who act for shipping companies' logistics services are also experiencing the burden of rising freight rates It is in a state of overheated competition and worsening profits for attracting shippers. For this purpose, research data, literature studies, statistical data and data from overseas specialized networks were used as prior research. Online surveys and telephone interviews were conducted, and as a result, four areas of cold chain (including perishable cargo), project logistics, UN procurement logistics, and dangerous goods logistics, which were found to be particularly in high demand, were analyzed to suggest entry strategies.
