摘要

過去倉儲管理一向是各企業中屬於較為浪費成本與時間的一環，根據過去的文獻顯示，倉儲作業中所需要的人力與成本大部分都在於揀貨活動，特別是在豐田式生產管理(Just-In-Time)、生產週期時間縮短(Cycle Time Reduction)和即時反應(Quick Response)等需要快速回應的生產方式的提出。有鑑於此，我們利用無線射頻技術建置一套即時定位系統，此系統是使用倒傳遞網路演算法得到物品的所在位置，另外，我們將這組定位裝置用於揀貨活動中，探討定位裝置對於揀貨活動所能帶來的整體效益。在揀貨系統中，當有臨時訂單的加入或是訂單有變更，能透過這套系統即時得知揀貨車的位置並計算是否揀取緊急訂單，同時指示揀取所有物品的最佳揀貨路徑。我們也針對無線射頻技術運用於揀貨系統的進出貨流程做一完整的規劃。本研究所提出的系統能即時做出妥善的規劃，且減少無謂的紙張作業，而對於臨時訂單的產生也能快速回應。

In the past decades, warehouse management system has been generally considered as a bottleneck in the whole organization of business. According to the literature, the cost of order picking activity is the major expense of operating in a typical warehouse due to the introduction of new operating programs such as Just-In-Time, cycle time reduction and quick response. For these reasons, we propose a simulated RFID-based order picking system to improve efficiency of operating in the warehouse, especially deal with the important rush orders. Furthermore, a location sensing prototype system with the application of RFID and back-propagation algorithm for locating objects is also presented in this research. The main advantage of applying RFID sensing system is to enhance efficiency of operating via novel dispatching way based on instantaneous message advised from optimize route when the real-time information for a picker is received.
