Abstract:	由於近年來國家經濟結構與社會需求的改變，導致產業轉型與外移的現象更趨於全球化與國際化，在這種趨勢之下，企業對產銷供應鏈規劃的活動範圍已經從簡單的工作點或區間場所內的物料流動，漸漸擴展到企業內部多方物流功能的整合與企業間商業物流管理和供應鏈活動，進而發展到國與國之間的全球化物流作業有關的全球供應鏈管理型態。而物流的核心活動為倉儲及運輸，因此，倉儲營運績效的好壞，在整個供應鏈管理當中，扮演著極重要的角色。隨著環境的改變，消費者需求的多樣化，使得物流中心每天要處理許多訂單，大多數的物流中心仍需要大量的人力進行揀貨作業，而揀貨作業是項重要且繁雜的工作，能否在合理時間內完成揀貨作業、增快貨品流通速度並避免不必要的儲存成本，使商品能快速的運送到達顧客手中，將直接影響物流中心的經營成本與顧客滿意度。為了要更有效率的處理揀貨作業，如何規劃揀貨員的揀貨策略，以達到提高作業效率的目的，對於物流中心的營運績效、經營成本有著顯著的影響。本研究所探討的問題屬於物流中心內部訂單揀貨作業之研究，探討對象以捷盟物流中心平行式走道倉儲為主，針對特定時間內的所有訂單，在不同的情境之下，模擬出各種結果，藉此來判斷出在何種情況下，以什麼方法進行揀貨可以使揀貨效率最佳。以吾人所提出之揀貨路徑策略及訂單選取之方法，並搭配揀貨清單的分佈比例等，用模擬軟體測試其總行走距離、總揀貨時間以及系統總執行時間能否有效的減少，以期能達到最佳效能。 This study deals with the order-picking problem in a warehouse. The picking area of the environment has been divided into different zones. A picker often has to visit more than one zone to pick all items in an order. This environment has one important restriction – no more than one picker can simultaneously be in the same zone. This paper focuses on one problem of this environment, i.e. finding the best zone-visitation sequence a picker can follow. Three zone-visitation sequencing strategies –the dynamic zone-visitation sequencing strategy, the revised-dynamic zone-visitation sequencing strategy and the dynamic-revised zone-visitation sequencing strategy – are proposed and studied for the problem. And ten order-picking solutions are proposed and studied for the problem. Simulation experiments are conducted to evaluate the performance of the proposed strategies in three performance measures –Total System Running Time to complete the picking operations (RT), Total Travel Distance of pickers (Tdist.), and Total Picking Time of pickers (TBT). The simulation results show that the dynamic-revised zone-visitation sequencing strategy is better than the dynamic strategy and the revised-dynamic strategy ,no matter what the performance measures are.
