Radio Frequency Identification(RFID) is technology that identify products using radio frequency transmission. We read EPC from Tag in RFID environment, but we can see only what the identify objects are and it is too limited to get the additional detailed information by the EPC. Therefore many companies and organizations have studied RFID system in order to effectively use it. But the existing RFID system still has the complication that we should fully understand various knowledges, communicating ways, etc, and the insufficiency to support the application development in order to treat the business event of the related application. In this paper, I propose business event that we can conveniently use in FRID application and shows Business Event Framework. BEF which is able to deliver the business event produced to the application.

RFID events are large volume of stream data which come out continuously. Many studies have been done to detect a business event in RFID stream. However, the existing methods have many problems which increase unnecessary operations when business events do not satisfy minimum conditions. In this paper, to remove unnecessary operations, we define the minimum condition of business events and propose an efficient method that detects business events only when the minimum condition is satisfied. To check the minimum condition of business events, we register business queries in a query index. We detect business events using the query index and bitmap. It is shown through various experiment that the proposed method outperforms the existing methods.

In logistic environments, a process, in that it manages the flow of materials among partners, involves more than one organization. In this regard, a logistic process, as a combined process consisting of multiple sub processes, needs to be managed with controling interaction among partners. In achieving systematic management of a logistic process, traditional Business Process Management (BPM) cannot be used for the entire flow, since it lacks the ability to manage interactions among partners. Particularly in logistic environments where RFID technologies are used, how to deal with the connection between RFID event and logistic flow has not been properly addressed. To overcome this limitation, this paper proposes a new method of managing multi-organizational logistic processes based on RFID events. We define inter-workflow pattern, and suggest ECA(Event-Condition-Action) rules for auto triggering of logistic processes. To adjust the rules to RFID events, we invent RFID-based ECA rules using complex event. A prototype system has been developed for the purpose of demonstrating the effectiveness of our approach.

RFID(Radio Frequency IDentification)는 라디오 신호에 따라 반응하는 태그(Tag)를 이용하여 해당 사물을 인식하는 기술이다. RFID 이벤트의 특징은 짧은 시간 내에 빠르게 생성되며 생성된 각각의 RFID 이벤트 정보는 단순하지만 대량의 이벤트들을 처리할 수 있으며 추가적인 정보를 태그에 담을 수 있다. 이러한 장점으로 물류나 재고관리 유통분야 등에서 RFID를 이용하여 시스템을 자동화하고 있다. RFID를 시스템에 적용하기 위해서는 RFID이벤트의 특성을 고려하여 시스템이 개발되어야 한다. 그러나 여전히 기존의 RFID 시스템은 해당 어플리케이션의 비즈니스 이벤트를 처리하기 위해 RFID에 대한 다양한 지식과 통신 방법 등을 이해해야 하는 복잡함을 가지고 있다. 뿐만 아니라 이기종의 플랫폼에서 개발, 동작하는 어플리케이션 개발을 지원하는 측면에서도 어려움이 있다. 본 논문에서는 다양한 이기종의 RFID 어플리케이션과 ALE를 지원하기 위한 비즈니스 이벤트 프레임워크(Business Event Framework, BEF)를 제시하였다. 또한 실제 이기종의 플랫폼에서 개발된 어플리케이션을 지원하기 위해 어플리케이션 매니저(AppManager)를 정의하였다. 마지막으로 RFID 관련 기술을 개발자가 모두 이해해야함을 최소화 하기위해 비즈니스 이벤트 스펙(Business Event Spec, BESpec)을 정의하였다.

RFID 응용프로그램은 필요한 기능을 수행하기 위하여 하위의 ALE Interface를 이용하거나 EPCIS 등의 외부 시스템과 통신을 해야 한다. 이러한 동작을 수행하기 위하여 해당 응용프로그램 개발자는 하위 ALE Interface를 사용하기위한 방법과 다른 추가 시스템의 사용법을 배워야 하고 정해진 통신 방법에 따라 프로그램을 작성해야 한다. 이러한 작업은 RFID에 대한 지식수준과 프로그래밍 실력에 따라 많은 시간과 노력을 필요로 하게 된다. 본 논문에서는 이러한 RFID 응용 프로그램 개발 시의 어려움을 최소화 하고자 Business Event Framework(BEF)을 제안한다. BEF는 비즈니스 로직과 직접적으로 관련이 없는 부분은 BEF가 직접수행하고 응용프로그램에서 꼭 필요한 이벤트만을 반을 수 있도록 지원하는 라이브러리이다.

Recently, there have been several researches on automatic object identification and distributed computing technology to realize a ubiquitous computing environment. Radio Frequency IDentification (RFID) technology has been applied to many business areas to simplify complex processes and gain important benefits. To derive real benefits from RFID, the system must rapidly implement functions to process a large quantity of event data generated by the RFID operations and should be configured dynamically for changing businesses. Consequently, developers are forced to implement systems to derive meaningful high-level events from simple RFID events and bind them to various business processes. Although applications could directly consume and act on RFID events, extracting the business rules from the business logic leads to better decoupling of the system, which consequentially increases maintainability. In this paper, we describe an RFID business aware framework for business processes in the Electronic Product Code (EPC) Network. This framework is proposed for developing business applications using business services. The term "business services" refers to generated events that can be used in business applications without additional data collection and processing. The framework provides business rules related to data collection, processing, and management, and supports the rapid development and easy maintenance of business applications based on business services.

As an wireless identification technology, RFID is now extending its application area including logistics, medicine, and healthcare. Adoption of RFID demands high cost such as h/w, s/w, and so on. To adopt RFID, we need to evaluate validity of application area and feasibility of RFID S/W such as EPC Information Service (EPCIS), which demands a variety of RFID test datasets. In this paper, I propose a novel method for generating RFID business events dataset by means of the simulation of RFID application environment. Proposed method can generate near-real RFID event dataset by means of representing various RFID application environment into abstract network model based on petri-net. In addition, it can also be useful when determining adoption of RFID as well as when evaluating RFID system.

Adoption of RFID has become widespread including logistics, drug supply-chain, and healthcare. To adopt RFID, we need to evaluate performance and feasibility of RFID S/W such as EPC Information Service (EPCIS), which demands a variety of test datasets of RFID business events. This paper proposes a novel method for creating RFID business events dataset by means of the simulation of RFID infrastructure. Proposed model provides a flexible representation capability since this is based on well-known petri-net. In addition, it can also be useful when determining adoption of RFID as it supports simulation of RFID environment.

Recently, RFID technology has attracted considerable attention in many industry fields. The RFID environment requires a standard architecture for the smooth exchange of data between heterogeneous networks. The architecture should offer an efficient standard environment, such as a communication environment based on Web Services, PKI or Kerberos-based security, and abstract business processes which could be used in the diverse domains. Therefore, in this paper, we propose an Enterprise Application Framework (EAF) which includes a standard communication protocol, security functions, and abstract level business processes. The suggested architecture is expected to provide a more secure and flexible security management in the dynamic RFID application environments, and is expected to provide an abstract business event for the development of business processes which could apply RFID technology to the existing systems.

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.
