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.

Electronic Product Code Information Services(EPCIS) is an EPCglobal standard for sharing EPC related information between trading partners. EPCIS provides a new important capability to improve efficiency, security, and visibility in the global supply chain. EPCIS data are classified into two categories, master data (static data) and event data (dynamic data). Master data are static and constant for objects, for example, the name and code of product and the manufacturer, etc. Event data refer to things that happen dynamically with the passing of time, for example, the date of manufacture, the period and the route of circulation, the date of storage in warehouse, etc. There are four kinds of event data which are Object Event data, Aggregation Event data, Quantity Event data, and Transaction Event data. This thesis we propose an event-based data model for EPC Information Service repository in RFID based integrated logistics center. This data model can reduce the data volume and handle well all kinds of entity relationships. From the point of aspect of data quantity, we propose a formula model that can explain how many EPCIS events data are created per one business activity. Using this formula model, we can estimate the size of EPCIS events data of RFID based integrated logistics center for a one day under the assumed scenario.

This paper leads to separate a in-out data overload of integrated EPCIS event and suggests the method to effectively manage EPCIS repository for exchanging data smoothly. In order to verify a effectiveness, we measure the performance of the system using a simple testing simulation by comparing existing method and suggested method.

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 paper deals with the method which diversifies the data flow load of intensive EPCIS events and effectively manages EPCIS repository for exchanging data smoothly. In order to verify a effectiveness, we measure the performance of the system using a simulation by comparing the existing method with the suggested method.

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.

최근 전자 태그를 이용한 응용 서비스가 활성화됨에 따라 전자 태그의 데이터 처리에 대한 연구가 광범위하게 진행되고 있다. 따라서, 다양한 전자 태그로부터 수집된 객체 정보를 효율적으로 처리하기 위해 웹상에서 널리 사용되고 있는 XML 기반의 데이터 처리를 요구하고 있다. 이를 위해 EPCIS(EPC Information Service)는 EPC 관련 데이터를 공유하기 위한 표준인터페이스를 정의하였다. 현재 EPCIS 1.0 스펙의 Core Event Type은 EPC 네트워크에서 필요한 핵심타입들만을 정의하였고 적용 분야에 따른 비즈니스 context와 관련된 타입들은 정의하고 있지 않다. EPC 네트워크를 특정 비즈니스 영역에 적용할 때, Core Event Type 외에 추가적으로 정의해야 할 정보에 대한 타입 이 필요하다. 이에 본 논문에서는 이러한 비즈니스 영역에서 자주 사용되는 재사용 가능한 객체 타입을 정의하고 있다. 이렇게 정의한 객체타입과 EPCIS Spec에서 정의한 Core Event Type을 활용하여 해운 물류분야의 객체 정보 데이터 모델에 따른 스키마를 설계하였다.

EPCIS(EPC Information Service) 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. EPCIS Repository continuously stores and manages mass EPCIS Event input data from a great number of RFID devices simultaneously. The Hybrid DBMS can deal efficiently mass necessary data. This study suggest the plan which can efficiently manage EPCIS Repository using Hybrid DBMS. We offer three schema and stores EPCIS Event data to Altibase DB that can efficiently manage EPCIS Repository using Hybrid DBMS and compare the performance about three schema through simulations.

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.
