RFID是一種非接觸式的科技技術，利用無線電波去自動辨識環境中的人和物。RIFD技術已經被應用在很多領域裡，例如：情境感知、供應鏈管理、醫療照護，及資產管理等。在RFID的相關應用中，會產生大量的資料，以及這些資料的特性是離散的，使得使用者不易於處理與管理這些資料。

RFID事件是在特定時間發生的事件串流，串流中的事件具有邏輯關係與時間限制的特性，是一種環境中發生的事件，是藉由RFID讀取環境中的標籤所產生的。為了擷取商業程序中的商業事件及情境資訊，企業資訊系統必須從RFID中介軟體收集大量的事件串流以及處理串流中事件的複雜關聯去發現RFID事件。複合事件處理是一種技術與工具的集合，幫助我們了解與控制事件驅動的資訊系統。複合事件處理技術的目的是分析與淬取事件串流中事件的關聯性以及發現這些事件在環境中隱含的意義。複雜事件處理已經被研究與應用在許多普適計算的應用上，例如RFID及無線感測網路。

在不同的RFID應用上，像是倉儲管理與物流管理，複合事件處理能有效地偵測到RFID事件及其相關的情境資訊。為了RFID實務上的應用，在本篇論文中，我們提出了適用於 EPCglobal架構的標準資訊系統的RFID事件定義與複合事件處理為基礎的事件處理架構。

關鍵詞：RFID、RFID事件、複合事件處理、EPCglobal、RFID中介軟體、企業應用系統。

RFID (Radio Frequency Identification) is a non-contact technology, using radio waves to automatically identify persons or objects in the environment. RFID has been used on variety of applications, such as context awareness, supply chain management, healthcare, assert management, and so on. A large amount of data is created on RFID application and all of them are discrete so that users have a hard work to process and manage them.

RFID event, which is event streams occurred in an interest time with high logical relations and temporal constraint, is captured by readers observing tags in environment. For capturing business events with context information in business processes, enterprise application receives a large amount of event streams form RFID middleware and process their complex relations to detect RFID event. Complex Event Processing (CEP) is a set of technology and tools to help us understand and control event-driven information systems. The goal of CEP is to analyze and extract the relations among event streams and detect their implied meaning in the environment. CEP has been researched and applied in many applications of pervasive computing, such as RFID and Wireless Sensor Network (WSN).

In variety of RFID applications, such as warehouse management and logistic management, CEP can detect RFID events with context information efficiently. For practicing on RFID application, in this thesis, we propose the definition of RFID event and a CEP-based event processing architecture on EPCglobal infrastructure.

Keywords: RFID, RFID event, complex event processing, EPCglobal, RFID middleware, enterprise application.
