無線射頻辨識(RFID)在自動辨識上有很高的功效,可以減少生產製造上的浪費及人為失誤的產生,更能達到自動化生產的運作。其次,利用RFID標籤之中所儲存的產品電子編碼(Electronic Product Code; EPC™),可以將RFID應用藉由EPCglobal Network™來達到資訊分享的目標,使其應用延伸至製造、運輸、甚至售後服務的範疇。 RFID系統是無法單獨靠著標籤(Tags)、讀取器(Readers)與中介軟體(Middleware)等即可運作的,若無資訊系統提供儲存與查詢之機制,則RFID系統所蒐集到的資訊也只是儲存在資料庫的一堆資料而已。除此之外,RFID系統在運作時,仍需與目前企業內部與企業之間的資訊系統做結合,因此就有EPCIS(Information Service)的出現。 雖然RFID在組織內部的應用已經相當成熟,但是在組織與組織上的應用仍屬於探索性發展階段,較無完整的系統雛形與相關應用可供參考,也無法得知實際的運用狀況。因此本研究主要針對EPCIS系統的功能面著手,定義出的系統功能與運作方式,並探討各組織內部的EPCIS系統如何藉由XML(eXtensible Markup Language)與企業、以及系統之間進行溝通。我們藉由建立一個EPCIS系統雛形去驗證EPCIS對於供應鏈管理上可能的訊息交易流程與系統實作,功能包括存貨追蹤、改善交易流程、異質性系統溝通,本研究提供EPCIS系統實作之經驗,藉此提供企業建置無線射頻系統之參考。
Radio Frequency Identification (RFID) can work efficiently in identification. RFID can reduce the waste in producing and negligence to achieve automatic production. Furthermore, we can also use Electronic Product Code (EPC™) stored in the tags to share information and extend to other areas such as manufacturing, transportation, and service. RFID system can not work just by tags, readers, and middleware. If RFID cannot provide data storage and query functions, the information collected by RFID system is nothing more than a pile of data in the database. Furthermore, a working RFID needs to connect with information systems in business and among businesses. Therefore, EPCIS (Information Service) was established. Though application of RFID is mature in organization, the application between organizations is still in the process of exploratory development. We don’t have complete model to refer so we are not sure the application in reality. Therefore, this study focuses on the functions and operations model of EPCIS. We discuss the functions of EPCIS in an organization to understand how to communicate with internal systems by XML (eXtensible Markup Language). We build a prototype system to prove the concept of message exchange procedure. The functions include tracing inventory, improving transaction procedures, communication of heterogeneous systems in order to setup an RFID reference for enterprises.
