藉由活用既有的RFID與網路科技,EPCglobal Network™ 扮演著在供應鏈中傳遞移動物件即時資訊的角色。EPCglobal Network™ 可被當作橫跨供應鏈、企業、全球的資訊蒐集、運用與溝通的一個媒介。 EPCglobal Network™是由多種元件所組成,而EPC IS (Information Services) 則是構成元件裡其中的一項。EPC IS 系統有如在網路架構中的網頁伺服器(Web Server),可以提供資訊給有授權的組織進行查詢使用;而在企業進行對於EPC IS系統的查詢前,必須先藉由EPCglobal Network™中的ONS (Object Name Service)元件,用以搜尋符合所貼附RFID之EPC的EPC IS,來進行產品資料的存取。 逆向物流可以滿足回收再利用、維修與廠商回收產品等需要,而當進行其中的維修與RMA等逆物流流程時,有時需要藉由正向物流中的資訊,來當作判斷的依據;而RFID與EPCglobal Network™的特性可以提供正向物流中,從原物料到售後服務相關的資料蒐集。這些藉由RFID與EPCglobal Network™所蒐集的資訊,可以幫助維修與回送貨品等流程更加順利。本研究提出一個EPC IS在LCD TV產業中,可能的維修使用流程設計與系統實作,以作為未來研究者探討RFID應用於逆物流的參考依據。
Leveraging existing Radio Frequency Identification (RFID) and Internet technologies, the EPCglobal NetworkTM will convey real time data about individual items as they move through the supply chain. With the EPCglobal NetworkTM, there is a medium within which information can be collected, utilized, and communicated across supply chains, across industry and around the world. EPCglobal NetworkTM contains several components, and EPC IS (EPC Information Services) system is one of these. EPC IS system is like Web Server in the network which can supply information for authorized parties’ requests. Enterprises can use ONS (Object Name Service) to search for the EPC IS to fit in with the items they have got. Reverse logistics is needed for recycling, repair, or returning to vendor. The repair and RMA (Return Merchandise Authorization) in reverse logistics sometimes need the information from the forward logistics in the supply chain and the characters of RFID and EPCglobal NetworkTM are able to support more information of product from raw material to after-sale customer care. The information collected through RFID and EPCglobal NetworkTM can help the repair and return product process more smooth going. This paper investigates the possible use cases of EPC IS in LCD TV supply chain.
