摘要

為了因應國際代工與全球產銷體系的形成，物流管理成為一個具有改善空間的重點，以達成增加轉運效率與降低成本之目標。而無線射頻辨識技術(RFID)便是可解決此問題之科技。但由於RFID系統屬於新興產品且需要長時間運作，其產品可靠度將會是一大問題。因為當該系統發生失效時，將會伴隨許多問題，例如：生產線的停擺、進出貨的延遲等，造成企業重大的損失。
本研究選擇RFID讀取器做為研究對象探討其產品可靠度，其內容為兩部份。第一部份則是採用故障預測與健康管理概念選定輸出功率做為產品性能參數指標，以此參數指標判斷產品健康狀況建立預警機制。結果顯示受測樣本在50℃之加速壽命試驗條件下，其輸出功率之平均數偏移衰退起始點為第41天，標準差增量衰退起始點為第39天，並在上述衰退起始時間點發出警報。第二部分則是運用該產品客退資料推估產品期望壽命值約為3819(天)，接著運用Naïve模型預測產品在保固期內產品失效數量上限為21(台)，以提供給廠商做為訂定保固政策之參考。

The RFID has become a solution technology to cope with the trends in international outsourcing and global logistics. However, there is lacking reliability data of the RFID products. As RFID system fails during its operation stage, issues include production facility shutdown, shipping delay of shipping, etc. This research aims at RFID reader and investigates its reliability. First, the output power is used as the index of product performance for the pprognostics and health management to judge the products’ health condition. Results shows that the average output power of the test samples deviates from nominal after 41 days at temperature condition of 50℃. The increment of standard deviation occurs after 39 days. Early warning mechanism initiates at this moment. Secondly, based on the RMA data, the expected life time is 3819 days. The Naïve model predicts that the upmost product failure within its warranty term is 21.
