在兩階段組裝排程的相關文獻中，通常不考慮設置時間 (Setup time)。然而，在很多實際的製造環境中，第一階段常牽涉到設置時間。此論文將焦點放在兩階段組裝且包含設置時間之問題，且更進一步討論多個共同元件的問題，目標式設定為最小化最大完工時間。因為此問題已被證明為NP-hard，所以我們提出一個啟發法求解此問題，並以下限值評估啟發法之績效。實驗結果證明，此啟發法可在極短的時間內得到近似最佳解，其平均誤差為0.714%。

In the scheduling literature about the two-stage assembly, the setup time is often ignored. However, an explicit consideration of setup time in the first stage is usually required in many practical manufacturing environments. This thesis considers a two-stage assembly scheduling of product problem with setup time to minimize the makespan (or maximum completion time). In this problem, the product consists of one or more common components. Since the problem is NP-complete, we propose a heuristic to solve the problem and evaluate the performance of the heuristic by a tight lower bound. Computational results show that the heuristic can obtain a near optimal solution in almost zero time and the average percentage deviation is only 0.714.
