在美國軍方、零售業者沃爾瑪（Wal-Mart）以及各界的推動下，無線射頻辨識技術（Radio Frequency Identiflcation，RFID）被認為是影響全球產業發展之重要技術，極具未來發展性。本研究針對一個零件供應商，實際導入精實生產與RFID技術以提升其倉儲作業效率。利用價值溪流圖分析製作現行流程圖（As-Is Model），並重新設計未來改善後流程圖（To-be Model）。經過測試結果顯示，每位作業員每天處理的棧板及貨物數量可以分別提升457%及429%。總作業時間由現行模式改變至未來模式可減少36%，而搭配越庫（Cross Docking）作業，總作業時間更可以減少46%。

With the push from US military, Wal-Mart and the other industry leaders, Radio Frequency Identification (RFID) has become one the key technology influencing the industry development all over the world. This research selected a spare part supplier and applied lean production and RFID technology to improve the warehouse operation efficiency. Value stream mapping (VSM) was used to draw current state map (As-Is model) and future state map (To-Be model with lean production and RFID) with material flow, information flow, and time flow. Preliminary experiments showed that the number of pallets and items processed by each operator were increased by 457% and 429%, respectively. The total operation time from As-Is model to To-Be model can be reduced by 36%. Moreover, performance on saving total operation time can be enhanced to 46% with cross docking.
