Nowadays there are many studies and there's huge development about USN/RFID which have great developmental potential to many kinds of applications. More and more real time application apply USN/RFID technology to identify data collect and locate objects. Wide deployment of USN/RFID will generate an unprecedented volume of primitive data in a short time. Duplication and redundancy of primitive data will affect real time performance of application. Thus, security applications must filter primitive data and correlate them for complex pattern detection and transform them to events that provide meaningful, actionable information to end application. In this paper, we design a ECA Rule system for security monitoring of exhibition. This system will process USN/RFID primitive data and event and perform data transformation. It's had applied each now in exhibition hall through this study and efficient data transmission and management forecast that is possible.

Policy base management system that can satisfy various user's request in distributed system environment recently and manage network resources efficiently is required. Described policy base management information consisted of ECA(Event-Condition-Action) rules so that efficient management of various communication network and consistent management policy may be available in this paper. Policy is consisted of Event, Condition and Actions to achieve when condition is satisfied. And we can present formality of dynamic function of management object as applying policy to ATM congestion control model been applying in real environment.

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.

최근의 에이전트 시스템 연구는 간단한 작업을 처리하는 단일 에이전트들이 모여 하나의 서비스를 제공하는 멀티 에이전트 시스템 분야에서 활발히 이루어지고 있다. 이러한 멀티 에이전트 시스템에서는 요구된 서비스를 구성원들이 효율적으로 협동하여 제공하기 위해 이들을 통합하고 실행순서 등을 조정하는 것이 중요하다. 본 논문에서는 계획, 그룹, 작업의 세가지 단계로 구분되는 규칙과 ECA 규칙을 사용하여 계층적 작업흐름을 정의하고 이를 통하여 에이전트들을 조정하는 방법을 제안한다. 계층적 작업흐름의 사용으로 기존의 방법과 달리 에이전트를 계층화하여 새로운 서비스를 구성할 경우 세부적인 수행사항에 대한 언급없이 상위 단계의 계획 규칙만을 지정하여 구성할 수 있는 장점이 있다.

The requirement of distributed multimedia applications is the need for sophisticated QoS(quality of service) management. In terms of distributed multimedia systems, the most important catagories for quality of service are a timeless, volume, and reliability In this paper, we discuss a method for increasing reliability through fault tolerance. We describe the design and implementation of the ECA running on distributed multimedia environment. ECA is a system is able to classify automatically a software error based on distributed multimedia. This papaer explains a performance analysis of an error classification system running on distributed multimedia environment using the rule-based DEVS modeling and simulation techniques. In DEVS, a system has a time base, inputs, states, outputs, and functions.

As the size and complexity of networks increase, it is difficult to manage the whole network using single network manager, thus it is more resonable to manage the network using several network managers distributed on the network. Security interoperability should be supported among network management systems (NMSs)that use different management policies. In this paper, an algorithm that makes it posible to take a role into a role lattices is suggested to provide security interoperability among NMSs that have their own role lattices. In addition, security constraints are proposed to maintain the confidentiality and integrity of information by dynamically modifying the access rights of roles as the state of a system changes. Also, the security constraints are expressed using ECA rules in this paper.

능동 데이터베이스 시스템은 일반적인 데이터베이스 시스템과 달리 어떤 사건이 발생하면 조건의 성립 여부에 따라 적절한 반응을 자동적으로 실행하는 시스템이며, 능동성은 사건, 조건 그리고 조치로 이루어진 능동규칙에 의해 수행된다. 그러므로 능동 데이터베이스는 규칙의 개념이 중심이 된다. 규칙은 사용자와 응용프로그램 또는 데이터베이스 관리자에 의해 정의되며, 대부분 일반적인 형태인 ECA로 이루어져 있다. 따라서 본 논문에서는 에너지관리 시스템에 적용하기 위한 능동 규칙 시스템의 구조에 따른 능동규칙을 일반적인 규칙언어 형태를 바탕으로 설계하고, 다양한 응용시스템에서의 확장성을 제시한다.

인터넷의 발달로 인해 조직 안의 마케팅, 광고, 조달, 판매, 서비스 제품 기획 등의 각 부분들간의 전자상거래와 조직간의 전자상거래, 그리고 빠르게 변화하는 기회를 잡기 위해 모인 기업의 컨소시엄의 형태인 가상기업에 대한 관심이 고조되고 있다. 이러한 조직내/조직간의 전자상거래와 가상기업에서 수행되어야 하는 비즈니스 프로세스를 통합, 향상시키기 위한 활동이 웍플로우 시스템이다. 웍플로우 관리 시스템은 기업의 비즈니스 프로세스를 정의하고 수행하며, 이를 추적하고 리엔지리어링한다. 하지만, 비즈니스 프로세스는 오랜 수행 기간과 복잡한 비즈니스 규칙등으로 인해 정확하고 신뢰적으로 수행하는 데에 많은 어려움을 가지며, 따라서 웍플로우 관리시스템은 비즈니스 프로세스의 자동화 및 개선을 위해서 작업 수행의 정확성과 신뢰성을 제공할 수 있어야 한다. 본 논문은 Event-Condition-Action(ECA) 규칙을 사용하여 비즈니스 프로세스를 올바르고 신뢰도 있게 정의ㆍ수행ㆍ분석ㆍ개선할 수 있는 트랜잭션의 지원을 위한 통합적이고 체계적인 프레임워크를 제시하고자 한다. 또한 웍플로우 모델과 그에 수반되는 오류 모델을 함께 제시하고 Petri Net으로 비즈니스 프로세스를 분석하는 방법론을 제시하고자 한다.

Close collaboration among businesses is required in B2B EC environment. Furthermore, emergency requests or critical information among businesses should be processed in an immediate mode. Most current systems, however, due to firewalls for the systems' security and autonomy, can not handle these requirements appropriately, but handle them in an ad hoc manner In this paper a method of timely collaboration among businesses and an active functionality component to support it in B2B EC environment are proposed. Since the active functionality component supports high level ECA rule patterns and event-based immediate processing, system administrators and programmers can easily program and maintain the timely collaboration independently to the application logic. The proposed active functionality component uses HTTP protocol to be applied through firewalls and is designed using a commercial DBMS for practical purpose.

Nowadays, the web service was based on composing the e-business and distributed computing environment. But existing workflow management systems have many problems with the interoperability between companies because they are made before most web services. For these problems, the workflow based composition language such as the Business Process Execute Language for Web Services (BPEL4WS or BPEL) appeared in expressing the web service composition. In this paper, we present an event based rule management system architecture that executes automatically the BPEL using the Event-Condition-Action (ECA) rules. The event based rule management system consists of the event manager, rule manager, and Jess. The Jess is the part of executing and deciding the condition.
