摘要

近年來隨著世界經濟的全球化、市場競爭激烈程度的增加以及網路通訊的發展，物流產業不得不進行革命與創新，期望生產場所與消費市場的距離能夠拉近，並且能減少生產時間與消費時間的落差，迎向新的二十一世紀消費爆炸的時代。透過物流中心的設立，使得通路產生變革，其可有效簡化配送頻率，並提高物流作業效率。故如何找出一種好的策略模式，降低從進貨到出貨的作業時間與成本，這對於物流中心的運作效率的提升將有非常顯著之影響。
本研究運用越庫作業為物流作業中的一種策略，其強調品項由供應商送至物流中心，品項依照訂單的順序分類處理，等到訂單完成後直接送到出貨碼頭進行出貨，且其中品項不需儲存在物流中心裡。故在越庫作業的環境中，可以消除品項的進貨、入庫、儲存以及揀貨等作業，使品項從進貨到出貨的時間最小化。
本研究針對使用越庫作業之物流中心所延伸出的兩種決策問題進行探討，分別提出相對應的暫存區品項指派法則以及理貨區服務法則，並且藉由模擬的方式得到的數據，比較在此環境下所產生的總系統執行時間，哪種因子組合的搭配將會對此作業效率有顯著的提升。

In recent years, with the increase of the economy globalization, market competition and the development of network communications, logistics industry had carried out the revolution and innovation, and expected to shorten the distance between shop floor and consumer markets. It can reduce the disparity in production time and consumption time to greet the era of consumer explosion in the twenty-first century. Channel revolution through the setting up of a logistics center, which can effectively decrease the distribution frequency, and improve the efficiency of logistics operations. Therefore, how to find a good strategy to reduce operating time and cost from inbound to outbound, which will have a significant impact to help the logistics center enhance the operational efficiency.
This study is used cross-docking as a strategy in logistics operations. We set items can transport to the logistics center by the supplier, and classify them in accordance with the orders. After the orders are completed, these items directly transport to the outbound dock waiting for shipping. In addition, the items do not need to store in the logistics center. Hence, we can eliminate items on the inbound, putaway, storage and order picking operations in the cross-docking environment, so that we can find the shortest time from inbound to outbound.
We use two decision-making strategies. First is ‘the assignment rule of temporary storage area.’ Second is ‘the service rule of Tally Zone.’ Our data obtained by the simulation way, and we compare the total system time in our study environment. Also, we paired analysis of which two rules match will significantly enhance the operational efficiency.
