工作調度、投料及派工是半導體晶圓製造工程中不可或缺的重要角色。工程師致力改善這些項目，以縮短在製品數量、提升生產良率，同時也為了達到更高的達交率。已有許多研究著重在探討生產線平衡及在製品數量的控制，以便了解何種派工或投料法則能為既有的生產線帶來更大的效益。但這些研究較少考量人力對於投料及派工法則的影響。若生產線中仍以人力進行搬運、上下料及備料的作業，可以稱該產線為「半自動生產線」，其人力作業未必能提高產品價值，卻會影響產品生產週期及物品在產線中流動的狀況。在這樣的環境之下，有限人力可能會帶來機台及物品的等待，進而影響系統資料的可信度。這篇研究設計動態投料法則，並應用系統模擬分析各種投料法則在「無限人力」及「有限人力」的環境下。首先探討有限人力對於半自動生產線的影響，其次提供產線基於「無限人力」及「有限人力」的投料標準及決策流程。個案研究結果顯示：生產效益會因有限人力的限制下降，生產週期時間也會因此增加；導入本論文所提供之動態投料法則後能有5%的改善，且DDR法則能控制80%的料件在不同人力限制時有更穩定的生產週期時間。

Job dispatching plays an important role in semiconductor wafer fabrication processes, the goal is to decrease work-in-process (WIP), have a better yield rate, and to satisfy the due date. Most researches focus on how line balancing and WIP controlling effect the decision flow while dispatching, however, not every wafer fab process is fully automated. Factories that required operators to handle materials or works are considered semi-automated, and the finite workforce may cause materials waiting for operators to move or to monitor. As a result, a dynamic dispatching rule considering finite workforce is proposed for semi-automated wafer fab line. A case study is demonstrated by simulation to present the conclusion. The results show that finite workforce will decrease throughput amount and increase cycle time. By the dynamic dispatching rule proposed in this study, both throughput and cycle time have significant improvements.
