The RFID market seems to grow mostly in the logistics and distribution areas. The areas and small sized work places requires multi-steps based system. In the environment, the performance of RFID READER is the most important factor. If RFID READER fails to operate frequency well, it will be difficult to apply RFID technology to work places and manage multi-readers used in a narrow place. This work reveals that making possible multiple readers environment and reporting the state of the entire upgrade are of significant in terms of the system's functions. This thesis studied RFID reader platform with self-diagnosis function.

Although the port distripark concept and its development policy have been introduced since almost twenty years, there is no visible results of the policy. Specifically, the level of value-added logistics using transhipment cargo is too low. In this paper, we mainly focus on the causes of the policy failure of port distripark's value added activities in terms of conceptual as well as practical or functional. Definitely, the study reviews the concept of port distripark compared to industrial park or bonded factory. The study also analyzes the differentiation of port distripark and port hinterland. The study generats that the problem or error that may occur when port hinterland is identified with the port distripark. Last but not least, the limitations of value added logistics is generated on the study. We examined in depth whether the already well known value added activity of port distripark is really activities that add 'value'.

This study investigates the initiatives of Gangwon sea routes based on precedent studies on the North Pole route to suggest a multi-modal buildup of transport logistics network of Gangwon harbors for the strengthening of logistics efficiency in the Korean Peninsula. The findings were: First, the government should expand railway infrastructure in Gangwon. Second, harbors in Gangwon should each have one speciality to strengthen connection with other harbors by using railway oriented background transportation network. Third, the government should develop industries of EFEZ(East coast Free Economic Zone) in the East Sea Coast in Gangwon to connect resources from the North Pole Sea. Fourth, the government should invite the base of Araon Ho's polar research vessel to play the role of the North Pole Sea route in the near future. Fifth, the government should strengthen the role of the Samcheock LNG base under construction. SIxth, environment-friendly transportation technology should be introduced to reduce carbon emission as much as possible. Lastly, an optimum North Pole logistics route should be developed to connect the Metropolitan area(Metropolitan Economic Zone), Gangwon roads and railway, Gangwon habor, Trans-Siberian Railway and thw North Pole route, and Europe, to strengthen national foreign trade power in the near future.

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.
