摘要:	本研究所探討的為播種式揀貨系統，物流中心中的電子標籤輔助揀貨系統可分成「摘取式（Pick-to-light）」與「播種式（Put-to-light）」兩種，所謂「摘取式揀貨系統」即貨架上安裝的標籤所對應的是商品，揀貨人員依標籤的指示，自貨架上將商品取下以滿足手上的客戶訂單；至於「播種式揀貨系統」跟「摘取式揀貨系統」正好相反，貨架上安裝的標籤所對應的是客戶訂單，揀貨人員將批次匯總後之商品，依標籤的指示，並分發至訂購客戶架上。本研究主要針對「播種式揀貨系統」的揀貨作業環境下做品項批次化為探討重點，並在傳統播種環境下加入RFID的揀貨彈性與資料即時傳遞訊息，使整個揀貨環境能夠更有彈性且增加揀貨效率。本研究主要可分為兩個階段：第一階段為種子品項選取問題、第二階段為品項批次選取問題。其中第一階段與第二階段稱為品項批次問題。本研究將針對「品項批次化揀取」問題做有系統的整理與比較。以七種種子品項選取法則、八種配合品項選取法則並搭配最短路徑插入法進行互相搭配。並評估比較揀貨路徑的長短，已期得到較佳的品項批次組合方法，來縮短揀貨行走之總距離，進而降低揀貨作業的時間與成本，提高揀貨效率。 The Study is based on the picking operation of “Put-to-light” System. According to the picking operation in Distribution Centers, the Computer Aided Picking Systems could be divided into “Pick-to-light” and “Put-to-light”. In the “Pick-to-light” system, the digital tags on racks correspond to items and indicate pickers to pick items. In the other hand, the tags correspond to customers’ orders in the “Put-to-light” system. Pickers batch the necessary items of these orders and then assort the needed items to orders by the indication of tags. This research will focus on item batching under the “Put-to-light” System’s picking operation circumstance, adding radio frequency identification(RFID) to increasing picking operation flexibility and information instantaneity in traditional put-to-light system’s circumstance, that will be flexible and efficient in the whole picking circumstance. This research will divide into two phases. The first phase is seed-item selected method, the second phase is item batching selected method. Both methods are combined, and we call them item-batching methods. This research will focus on item-batching methods, collecting systematically and compare with them. We have seven methods for seed-item selected methods, eight methods for accompany item methods arranging with Nearest Picking Zone First(NPZF). Evaluation and Compared with their picking distance, we expect that will obtain the best combination to reduce total distance about picking distance, reducing time and cost about picking operation, and enhance their picking efficiency.
