隨著RFID技術逐漸成熟,以RFID技術為基礎用在定位系統之研究也逐漸受到重視。而將RFID技術用在定位上,不僅可以用來提供方位辨識、追蹤移動的軌跡及最佳路徑分析等,也可以提供使用者所在位置的相關資訊。且根據過去的文獻顯示,倉儲管理一向是在各企業中較為浪費成本與時間的一環,尤其以揀貨作業是倉儲管理中最花成本的作業之一,其成本占了整個倉儲操作成本的55%。。 因此,本研究利用RFID技術為基礎來建置一個實際的揀貨環境,此系統是使用倒傳遞網路(Back-Propagation Network)方法將所收集到的訊號強度(Received Signal Strength Indicator, RSSI)進行分析,以得到揀貨人員所在之位置。另外,本研究也將此定位裝置應用在揀貨活動中,並探討定位裝置對於不同揀貨情境所帶來的影響。
As the RFID technology gradually matures, the research on the RFID technology-based positioning system has attracted more attention. The RFID technology applied to positioning can be used for orientation recognition, tracking moving trajectories, and optimal path analysis, as well as information related to the user's position. According to previous literatures, warehousing management consumes high cost and time in business operation, more specifically, picking is one of the most costly operations in warehousing management, which accounts for 55% of total warehousing cost. Therefore, this study constructed an actual picking environment based on the RFID technology. This system uses the back-propagation network method to analyze the received signal strength indicator (RSSI), so as to obtain the position of the picker. In addition, this study applied this locating device to picking activities, and discussed the effects of the positioning device on different picking situations.
