Exploration of Productivity Loss Function Due to Interface Interference in Semiconductor Plant Construction

高科技廠房與一般傳統工程有許多不同特性，如工程難度高、施工工期短、規模大及施工界面複雜等，且同步施工導致現場施作人員眾多，不同工班在同一個空間施作，產生許多施工界面衝突，直接影響工人之生產力，造成工程工期延宕，對於專案工程管控有極大影響。施工界面衝突使工地現場混亂，等待與擁擠造成生產力之折損程度，少有文獻予以量化，因此無法評估上述對生產力折減之嚴重程度。研究以半導體廠為例，透過訪談工地現場施作人員，將工班因施工界面衝突產生等待與擁擠之情形予以量化並比較分析，以模糊語意設計問卷(fuzzy verbal questionnaires)進行問卷調查，經過模糊統計(fuzzy statistics)分析後，得到不同工種與不同施工界面衝突處之生產力折減情形，再經迴歸計算後，建構出不同施工界面衝突下，不同工種間等待和擁擠情形對應之生產力折減曲線函數，並進一步分析比較不同施工界面衝突造成生產力折減值之差異，以及產生差異之原因。過彙整高科技廠房中常見之施工界面衝突，並以生產力函數將工班等待和擁擠問題予以量化，於實務上可依據施工現場狀況求得生產力折減之具體參數，以重新調整合理之生產力；並由此生產力折減函數來突顯影響工人生產力最為嚴重之施工界面衝突，在工程管理上需更注意避免其發生而影響整體工程，使工地現場狀況能有更佳的管控。Construction of High-tech manufactory plant is quite different from ordinary construction due to its tight schedule, complicate construction interference conflict, and concurrent engineering. Therefore, different trades may interfere with one another while working in the same space, and produce many construction interface conflicts. These construction interface conflicts produce chaos in a construction site, and affect labor productivity directly. Few researchers quantify the relationship of productivity with waiting behavior and crowded space of the different trades, and the severity of the productivity loss. Therefore, the purpose of this research is to explain productivity loss function due to interference in semiconductor plant construction.his thesis focuses on hi-tech semiconductor fab. Through on-site interviews with the construction experts, the waiting behavior and crowded space which are made by construction interface conflicts are quantified. The fuzzy verbal questionnaires were adopted in the interviews according to the construction interface conflicts types, and the interviews were recorded in the form of fuzzy intersection. After applying the fuzzy statistics, the parameter of each fuzzy verbal variable that causes the productivity loss was identified. Then the function of different types of construction interface conflicts of productivity loss was built, and the difference of productivity loss value and the reasons for differences were determined.fter collecting the common construction interface conflicts in hi-tech factory buildings, and quantifying waiting and crowded problems into productivity loss function, in practice, labor productivity loss value was obtained based on the situation of construction site. Then, it is readjusted reasonable productivity. In this way, the most serious construction interface conflict is highlighted, and more attention can be point to avoid the occurrence of the impact of the overall project. Then, it result in a better control of the project management.目錄謝 I要 IIIbstract IV錄 VI目錄 IX目錄 XI一章 緒論 1.1 研究動機 1.2 研究目的 2.3 研究範圍與限制 2.4 研究方法 3.5 本文架構 4二章 文獻回顧 5.1 高科技廠房之介紹 5.1.1 高科技產業的定義 5.1.2 高科技廠房的定義 6.1.3 高科技廠房施工特性 7.2 界面的相關理論 10.2.1 界面的定義 10.2.2 施工界面的定義 11.3 界面衝突相關理論 12.3.1 界面衝突的原因 12.3.2 施工界面衝突與生產力相關研究 13.4 模糊理論 16.4.1 模糊邏輯基本原理 16.4.2 模糊理論相關應用 18.5 小結 20三章 施工界面衝突之分析與建立 22.1 研究假設與定義 22.1.1 施工界面衝突產生之問題 22.1.2 空間衝突影響生產力之相關研究 23.2 施工界面衝突建立 25.2.1 施工界面衝突在高科技廠房中較容易發生之原因 25.2.2 施工界面衝突分析 27四章 施工界面衝突下之生產力折減函數 30.1 生產力折減函數之建立 30.1.1 生產力折減函數的應用原理 30.1.2 生產力折減函數 32.2 問卷訪談內容與對象 40.2.1 問卷訪談內容 40.2.2 問卷訪談對象 40五章 等待問題與擁擠問題造成之生產力折減函數 42.1 不同施工界面衝突處造成等待之生產力折減函數 42.1.1 餘料造成等待之生產力折減函數 42.1.2 鋼筋堆置區造成等待之生產力折減函數 44.1.3 施工架架設造成等待之生產力折減函數 46.1.4 鋼筋吊放造成等待之生產力折減函數 48.1.5 趕工工序造成等待之生產力折減函數 50.2 不同施工界面衝突處造成擁擠之生產力折減函數 52.2.1 餘料造成擁擠之生產力折減函數 53.2.2 鋼筋堆置區造成擁擠之生產力折減函數 54.2.3 施工架架設造成擁擠之生產力折減函數 56.2.4 鋼筋吊放造成擁擠之生產力折減函數 58.2.5 趕工工序造成擁擠之生產力折減函數 60.3 生產力折減修正函數 62六章 不同施工界面衝突之生產力折減函數分析 66.1 不同施工界面衝突對模版工生產力折減之差異 66.2 不同施工界面衝突對鋼筋工生產力折減之差異 69.3 不同工種產生等待問題之生產力折減差異 72.4 不同工種產生擁擠問題之生產力折減差異 75.5 生產力折減值差異探討 78.6 小結 79七章 結論與建議 81.1 結論 81.2 建議 82.3 未來研究方向 83考文獻 84錄一、本研究問卷內容 8
