近年來，產品生命週期日益縮短以及供應鏈的觀念興起，致使物流中心(Distribution Center ; D.C.)的作業已經成為各個企業競爭優勢所關注的焦點之一。傳統物流中心的揀貨作業其相關人力，約佔整體物流人力的50％以上，而揀貨作業時間佔整個物流時間之比例高達30％至40％。故揀貨作業的重要性，足以影響著物流中心的整體營運和作業成本。 物流中心的揀貨設施和系統也隨著科技的進步，有了嶄新的面貌，所以如何在傳統的環境之中加入創新的思維和技術以達到更進一步的揀貨效率提昇，是目前所需探討的課題。許多研究指出新興的語音引導揀貨系統(Voice Directed Order Picking System)擁有許多優點，如：即時的人員指揮、訂單準確度和生產量等，皆有助於揀貨作業的效率提昇和物流中心的整體績效。本研究觀察揀貨人員在揀貨作業時，因為面臨欲拜訪揀貨點為阻塞 (Blocked) 狀態的情形，故吾人利用語音引導揀貨系統之特性，進而針對揀貨路徑的規劃進行揀貨績效的探討。 本研究提出四個『揀貨路徑規劃法則』，並在三種不同的『訂單所需拜訪揀貨點數目』的環境因子下，探討其系統總執行時間、總行走距離和總揀貨時間的績效表現。而結果顯示出，在不同的環境因子下，吾人所提出的『揀貨路徑規劃法則』皆有效的提升整體揀貨績效，並且隨著『訂單所需拜訪揀貨點數目』之水準增加，其績效表現也有越來越好的趨勢出現。In recent years, the operation for distribution center become the focus of competition for enterprise due to the product life cycle shorten and the concept of supply chain emerge. The picking operation almost account over for 50% of overall logistic labor, and the picking operation process time account for 40%. So the importance of picking operation can affect enough the operation and cost.The picking operation related facility and system have the new face by the development of technology for the Distribution center. So how to introduce the innovational concept and technology in the traditional warehouse environment which achieve the rise of order picking operation is a issue worth to discuss and research. A lot of research point out the emerging 「Voice directed order picking system」 that possess many advantages which can help the efficiency rise of picking operation and overall performance in the distribution. center. This research discover the picker executing the picking operation which faces the situation of waiting to visit picking point is blocked, so this research use the characteristics of Voice directed order picking system to focus the issue about the performance of picking routes planning.This research propose the four picking route planning rules, and discuss the three environmental factor – the number of order require to visit picking point and the three performance indicator TRST, TD and TPT. The result shows picking route planning rules have good performance even in different environmental factor.
