  • Recently, as change in global logistics environment, various issues have been presenting. These issues are including the pursuit of low cost-high added value, the realization of sustainable logistics system, the protection of environment, and the development of ubiquitous techniques. To cope with these environment changes and improve the national logistics system, the government have carried out various logistics policies and pushed ahead development of national logistics information network. But still, from a view-point of national logistics, there are several inefficient elements such as information connection and utilization, code/data standardization. In this paper, the survey result of global logistics environment change, logistics policy of a developed countries, domestic logistics policy and information system status will be presented. And from these status, suggestive points are mentioned. Finally the status of railway logistics information and future developments are presented.

  • Number of researches on efficient terminal operation system applying RFID(Radio Frequency Identification) are in progress. However, RFID has limitations on tracking and providing accurate positions of containers. In this paper, to enhance the performance of the integrated terminal operation system, an efficient loading management of yard is proposed by applying RFID based RTLS(Real Time Locating System) that provides real time accurate positions of containers. It was found that a group based sequence system is more efficient than the existing individual sequence number system in the container yard In the group based sequence system, the containers in the same group should have similar characteristics such as port of destination(POD), size, weight, etc. In order to run this system, we proposed the parameters to the unspecified N bytes of RFID tag which are specified in ISO 18000 7. And then, we developed an integrated operation system of container terminal using RFID. The proposed system reduces the ship turnaround time in ubiquitous port environments.

  • Nowadays, ubiquitous computing services begin to be suggested from a few domains such as supply chain, logistics, and location-based services. However, to what extent the services will be successful is hard to be estimated, mainly because a sophisticated service evaluation method focusing on the ubiquitous computing perspective has not been supplied. Hence, this paper alms to build a model to assess the quality of ubiquitous computing service. To do so, an amended model, Ubi-SERVQUAL, is applied to assess the service quality mentioned in ubiquitous computing scenarios. According to the Ubi-SERVQUAL, we found that an actual service with higher quality should consider reliability. responsiveness, assurance and empathy in order to increase customer satisfaction, computer system's intimacy with users and trust.

  • Logistics creates a boom in accordance with the recent new technique's development along with the recent RFID/USN of ubiquitous computing technique. The wave of 4PL(Fourth Party Logistics) that added the strategic consulting based on new IT techniques to logistics outsourcing through existing 3PL service with is a great issue. Moreover, the customer enterprises which contained manufacturers and distributors need the one stop service, therefore a method for effectively dealing with global logistics' environment changes is needed. Above all, a development of the 4PL system with RFID is very urgent. We developed the RFID u-4PL system progressed more than the present system, in which we applied many international standards. Finally, we constructed the web service based on Web 2.0 because of important condition of 4PL.

  • A recent advance in RFID technology is one of the major technological drives in reducing cost in logistics, distribution and even in the manufacturing sector. However, currently the technology is practically accepted only in the area of logistics and inventory control. The characteristic of these application areas is that the technology is used in the controllable environment. In this paper, we discuss a case study of using active and passive RFID technologies to automatically gather process information in the mold factory. Active RFID tags are attached on the main parts of molds and their positions in the floor are tracked with the routers. We also discuss on the idea of using mobile device with RFID reader to inquire information for molds on the spot in the factory floor. The inquirable information includes 3D design data and basic mold data. The paper shows implementation results with hardware configuration for the testbed.

  • In recent, rapid and accurate processing for logistics have been required, according as logistics has grown dramatically. Especially, identifying, locating, or tracking objects in ports are important, because ports are gateways to extended markets. In this paper, we describe the design and implementation of a smart tag system for ubiquitous port logistics. Our solution consists of three parts: an active RFID to identify objects, an electronic container seal to charge with security of containers, and a RTLS system to locate objects. Because identification technology for logistics can be read by heterogenous systems, compliance with the international standard is one of the most critical issues. This paper introduces the method to maintain compliance with ISO, and conducts some verifications. In addition, we analyze the system performance such as lifetime, identification rate, and time for multiple tag identification.
