面板廠為了達到最具經濟效益的切割，玻璃基板往大尺寸發展是未來之趨勢，然而面板尺寸增加伴隨重量也變大，不論在機台設計或載具搬運上都受此影響，玻璃基板的搬運形成一個重要課題，由於人工搬運已無法負擔工作需求，因此物料搬運一般是藉由自動化物料搬運系統(Automated Material Handling System)來完成，自動化搬運對於平面顯示器產業之量產技術相形關鍵。
本研究以國內某面板陣列廠蝕刻製程之自動化物料搬運系統作為研究對象，針對現況環境STKT(Stocker)內兩台Crane搬運系統的負載率存在著不平衡之情形，提出改善方案，先以UML(Unified Modeling Language)為基礎之物件導向，作為模擬模式發展之主要工具，利用eM-Plant模擬軟體進行模擬模式建構，藉由系統模擬的方式輔助規劃STKT Hand-Off的位置選定與區域調整，以使加工中心內Crane搬運系統之運載負荷能有效平衡。
模擬數據經實驗設計分析顯示，在STKT Crane搬運系統中，Hand-Off區域位址與卡匣來到率之間存在顯著的交互作用，因此本研究在不同環境下，探討不同Hand-Off位置的選定對搬運系統所造成的影響，透過系統模擬的回饋特性，規劃出一個合理的Hand-Off區域位址，將可有效平衡STKT內兩台Crane搬運負荷量，提昇整體搬運效能，對系統產出也有顯著提升，並利用中央合成設計法則(Central Composite Design Method)，在搬運績效極值化的前提下，配置出STKT Crane搬運系統各項績效之迴歸模型，透過此評估方法，作為探討在不同環境下，預測不同Hand-Off設置區域對STKT Crane搬運系統之績效表現。

In order to get higher economic benefits, panel manufacturers are apt to make large-size glass substrates and by far it becomes a future tendency. Nevertheless, panel’s weight grows with its size and has affected bench design and transport carriers. Since transporting large-size glass substrates by manual handling can not meet the needs, this heavy task is now accomplished by an Automated Material Handling System (AMHS).
The research object is to study an AMHS handling etching processes in an array panel manufacturer located in Taiwan. To improve unbalanced loading rate existed in STKT (Stocker) crane transport system, object-oriented based Unified Modeling Language (UML) simulation models (eM-Plant) are applied. The simulation system assists planning STKT Hand-Off locations and adjusted areas, and the carrying capacity of the crane transport system in the machining center can be effectively balanced with its aid.
The result shows that while in STKT crane transport system, an apparent reciprocation can be found between Hand-Off area address and the coming rate of cassettes. Thus this study probes into different Hand-Off area selection in different environments to find out influences that the system causes, and by the feedback feature of the simulation system, a rational Hand-Off area address can be created to effectively balance the carrying capacity of the STKT crane transport system, enjoys better transport performance and doubles the output. On the premise of extreme transport performance, using Central Composite Design Method to dispose STKT Crane model on each performance of the transport system, and through this assess method to predict the systematic performance of STKT Crane transport system in different Hand-Off area addresses under different environments.
