EPCIS(EPC Information Services) system is a core component of EPCglobal Architecture Framework offering information of the freights, the time of awareness and the location of awareness on the EPCglobal Network. The role of EPCIS is to exchange information based on EPC. There are four kinds of event data which are object event data, aggregation event data, quantity event data, and transaction event data. These EPCIS events data are stored and managed in EPCIS repository. This study suggest the quantitative modeling about total number of EPCIS event data under the assumption to aware the RFID tags of items, cases(boxes), vehicles(carriers, forklifts, auto guided vehicles, rolltainers) at a time on the reading points. We also estimate the number of created EPCIS event data by the suggested quantitative modeling under scenario of process in the integrated logistics center based on RFID system And this study compare the TO-BE model with the AS-IS model about the total sizes of created EPCIS event data using the simulation, in which we suggested the TO-BE model as the development of the repository by skipping the overlapped records.

RFID(Radio Frequency Identification) is used to describe a system that transmits the identity of an object or person wirelessly using radio waves. RFID is recognized as a key technology of USN(Ubiquitous Sensor Network). ISO/IEC JTC1 and EPCglobal are developing RFID related standards for global supply chain management. RFID is an important solution not only for the supply chain management, but also for USN and future services. Recently, mobile RFID which provide various services using RFID reader in mobile phone, is being standardized in Korea. In this paper, we analyze trends of RFID standardization activities in ISO/IEC JTC1 and EPCglobal and mobile RFID, and propose an convergence scenario of IPv6 and RFID.

Recently, Ubiquitous Computing appeared to achieve service that is intelligence enemy without being courted in restriction that is time and space enemy based on developing computer network and Internet festinately. RFID (Radio Frequency Identification) technology that process information of tag that is attached in physical object by point technology that capacitate this Ubiquitous Computing through radio frequency identify is noted. Present RFID connection technologies are Auto-lD Lab and EPCglobal Inc. To center research for standardization progress. But, present RFID related researches connected with tag and leader are progressed vigorously and research about middleware or software description to service actuality tooth is insufficient misgovernment. In this treatise, therefore, characteristic of comparison and analyze about EPC network architecture proposed Auto-lD Lab and EPCglobal Inc. and conceptual application architectures had used existent application development and integration.

A RFID technology that process information of tag attaching in physical object by a point technology that enable this Ubiquitous computing through radio frequency is noted. One of our most important, location tracking for object in RFID system. With this in mind, proposed EPCglobal network gives the location tracking and location services. but, RFID system has the drawbacks. That is special construction and components be positively necessary for RFID system. The service difficult to integrate other service and it increases costs considerably. This thesis gives location service using RFID based on SIP in hospital.

RFID (Radio Frequency Identification) is a technology that can input identification information to microchip and make goods, animals, persons recognized, chased, and managed using radio frequency, and is founded on the core technology of ubiquitous environment of the future. In this paper, we propose a RFID integrated system designed to manage the lifecycle of an individual product efficiently. The proposed system can enable traceability and visibility of items through their entire life by integrating distribution and banking information on the basis of EPCglobal Network. It may provide the infra of Digital Manufacturing and RTE (Real Time Enterprise) and effective information sharing structure with existing legacy system (ERP, CRM, SCM) by real time.

The RFID(Radio Frequency Identification) and the WSN(Wireless Sensor Network) have technical similarities and mutual effects, they have been recognized to be studied separately, and sufficient studies have not been conducted on the technical integration of the RFID and the WSN. Therefore, EPC global which realized the issue proposed the EPC(Electronic Produce Code) Sensor Network to efficiently integrate and interoperate the RFID and WSN technologies based on the international standard EPC global network. The proposed EPC Sensor Network technology uses the Complex Event Processing method in the middleware to integrate data occurring through the RFID and the WSN in a single environment and to interoperate the events based on the EPC global network. However, as the EPC Sensor Network technology continuously performs its operation even in the case that the minimum conditions are not to be met to find complex events in the middleware, its operation cost rises. Therefore, to address the problems of the existing system, we defined the minimum conditions of the complex events to detect unnecessary complex events in the middleware, and proposed an algorithm that can extract complex events only when the minimum conditions are to be met. To examine the minimum conditions, a index and a query index are used to extract complex events. To evaluate the performance of the proposed methods, In the case of the method of extracting complex events based on a bitmap index, we used the existing extraction method and NS2 simulation to evaluate its performance and thus to show its good performance in terms of the number of operation and the processing time for the complex events.

Operating on its own to develop a system or based on the standard to setup and operating of RFID System. If you want to operate RFID system yourself then It is no problem to use its own to develop a system, but have to implementation RFID System based standard for the system integration and data linkage in multiple companies or base. In this paper, I propose an EPCIS Capturing Application of the element for applying an RFID-based EPC Network as an international civil standards organization EPCglobal. EPCIS Capturing Application generation is a message for transmission to EPCIS receives the data transmitted from the reader and middleware to serve to transfer the EPCIS. This paper also proposes Capture Interface capable of receiving the data of the equipment does not use the ALE Interface as a portable RFID reader ALE Interface, as well as used by the RFID reader to implement a fixed system for use in the field. In this paper, we propose a EPCIS Capturing Application for tracking the history RFID is applied to the finished product. It is possible to take advantage to be applied to all systems based on the EPCglobal standard through proposed the EPCIS Capturing Application.

These days RFID application has been developed rapidly. It has been applied to many business areas such as logistics and supply chains. The Electronic Product Code (EPC) Network Architecture, an open global standard, is proposed by EPCglobal for developing RFID enabled systems. People who want to obtain the product information which are master information and event information have to apply with EPC Network Architecture. However, EPCIS which has master information and event information has to be accessed base on each EPC. Therefore, there is lots of duplicate accessing to EPCIS because RFID application has to access the same EPCIS over again which makes all performance down in EPC Network. This paper proposes how to reduce access times to EPCIS using EPC grouping based on EPCIS address. We build EPC Network environment to experiment about performance of RFID application system and we prove the improvement of EPC Network. Our result shows the reducing the EPCIS communication time by maximum 99 percentages.
