In the recent years, the companies have manually recorded a production status in a work diary or have mainly used a bar code in order to collect each process's progress status, production performance and quality information in the production and logistics process in real time. But, it requires an additional work because the worker's record must be daily checked or the worker must read it with the bar code scanner. At this time, data's accuracy is decreased owing to the worker's intention or mistake, and it causes the problem of the system's reliability. Accordingly, in order to solve such problem, the companies have introduced RFID which comes into the spotlight in the latest automatic identification field. RFID is an automatic identification technology by radio communication technology that allows us to identify or record information without contacting the corresponding object, and as Gen2 and EPCIS, EPCglobal's standard tag for RFID, have recently been established, it will be introduced to the whole computation industry. This study suggests RFID type Modeling Notation for analyzing logistics flow to improve MES focusing on extended model of EPCIS, and EPCISEvent Template in manufacturing industry.

The application service to use recently an electronic tag have been activated. Therefore research about a data processing of an electronic tag have been processed widely. Therefore, object information to be collected efficiently from various former tag for requesting a data processing of XML based on used widely in Web. For this EPCIS defined the standard interface to share EPC relation data. Currently, Core Event Type of EPCIS defined the Core Type to need in EPC network currently and Types about a business context do not define according to Apply field. We apply to EPC network to a specific business We need the type about the information which defines with Core Event Type. in this paper. We are defining an reusable object type which is used often in a business area. in this way design the schema based to an object information data model of a marine logistics apply to the object type to define in this way and Core Event Type to define EPCIS Specnt.

EPC Information Services (EPCIS) is an EPCglobal standard designed to enable EPC-related data sharing within and across supply chain. The EPCIS standard defines standard interfaces to enable EPC-related data to be captured and subsequently to be queried using a set of service operations and an associated data model. There are two kinds of EPCIS data: event data and master data. Event data is created in the process of carrying out business processes. Traceability of goods across supply chain is based on event data. Therefore, each company must have an event data. This study compared he difference between MS-SQL(DRDBMS) and ALTIBASE(MMDBMS) for data storage. We compared the difference between two database management in many respects such as insert time and select time. We come to a conclusion that ALTIBASE is more efficient than MS-SQL.

EPCglobal Network is based on the Electronic Product Code(EPC) and rapidly opening up to many enterprises that have close relationships with each other. Since a huge amount of logistics Information is distributed in the EPCglobal Network, it needs to manage them effectively. Global logistics companies and institutes are studying and setting up the standards about EPC Information Service(EPCIS), Object Name Service (ONS) and EPC Discovery Service(EPCDS) in the RFID and EPC-based logistics information network. In this paper, we propose expanded EPCIS and EPCDS that are satisfy EPCglobal standards and enable more effective logistics information management.

Radio Frequency Identification(RFID) technology has been widely used to identify and keep track of physical objects. The EPC Network Architecture, which is proposed by EPCglobal to promote EPC and RFID technologies, consists of several layers to deal with the captured data. Many studies concentrated on dealing with RFID tag data (ECReports) from ALE. However, there is no well-known work on specifying how to generate high level EPCIS events. For the incoming ECReports, Capturing Application cannot decide to generate which event types and how to get the semantic fields. In this paper, we propose the new Capturing Application (NCA) to solve the problem. NCA can generate EPCIS events correctly and automatically.

Obtaining and applying information is considered as a critical task in the modern informationized society. Finding the one's necessary information and processing it into a detailed knowledge are becoming more priortized in the enormous amount of information. Data modelling is the process that does not only reflect the demands of the user but the one that also facilitates the user's comprehension of the model itself. Ultimately, data modelling fully supports the processes that are requisite for the implementation of a data base and minimizes the alternations of the model during the development of applications.

RFID/USN, are recognized as the new growth engines for the future, regardless of the advanced and developing countries. RFID, in particular, already entered practical stage by global companies. EPCIS, which is the one of the EPC golabal network components, makes a huge load on the system due to the large amount of entering data by following events. In this study, a data model developed based on ER-WIN by collecting four kind information that occurred in the EPC global networks. This model supports both in processing of high performance and huge capacity of data by a considerable storage capacity and input speed. A simulation was developed in order to verify the performance. Each model tested several times and results were compared.
