摘要

Manufacturing strategy focuses on manufacturing activities that have pervasive and long-term impact on a company and thus requires dynamic conformance with corporate strategy, business strategy, and marketing strategy. Manufacturing strategy decomposes manufacturing objectives into measurable metrics and corresponding manufacturing practices through strategy formulation and further implements alternatives chosen, measures performances, and achieves objectives so as the profitability and sustainability of a company can be closely linked with the company’s resources and capability. This research aims to propose a framework for structuring manufacturing strategy decisions and conduct empirical studies in semiconductor backend manufacturing for validation. Manufacturing strategy decisions constitute manufacturing strategy through a series of decision making processes and corresponding problem-solving. Indeed, the underlying decision-making sub-problems that can be formulated in a wide spectrum of forms with regards of the problem natures involved in manufacturing strategy decisions. Firstly, this study utilizes an extended influence diagram to structure various problem types and proposes different solution strategies. Then, a UNISON decision analysis framework is employed for the problem-structuring process, in which important characteristics of real problems can be extracted step by step. Finally, semiconductor backend problems in real settings are introduced to validate the proposed framework. The research findings have shown that different problem structures demand different methodologies for solutions in part of them involving decision-maker’s preferences. The proposed framework can assist the decision makers to structure complex manufacturing strategy decisions while considering causal relationships among the decision elements and variables.

製造策略致力於製造活動的改進並對企業的影響廣泛且長遠，因此必須不斷動態調整以配合公司策略、營運策略與服務策略。製造策略藉由策略形成的過程以展開製造目標、衡量尺度間關係至製造實務，並進一步執行方案、衡量績效與目標的達成，將企業獲利與永續發展的命脈與企業能力與資源結合。本研究目的係建構製造策略決策分析架構，做為一般化製造策略架構的工具，並發展對應的方法論，然後藉由半導體後端生產的實證研究來驗證本研究的效度。事實上，製造策略決策則是藉由一系列決策制訂過程的評估與問題解答的提供來擬訂製造策略。其中，包括以不同形式呈現的子決策問題。本研究首先探討製造策略中製造目標、績效評估與製造實務的重要特徵，並解釋各元素間因果關係的重要性與鑑定規則。接著，本研究根據事實前提、價值前提與因果關係定義與分類問題架構。除此之外，本研究利用所擴充的影響圖工具架構上述不同種類決策問題並說明不同問題的解決方法。本研究並根據紫式決策分析架構（UNISON）來解釋問題架構的過程，以從真實問題萃取重要特徵。最後，本研究藉由對半導體後端生產的實際問題的討論來說明驗證整合問題架構的相關議題及本研究所提出的解決方案。本研究發現針對不同程度的問題架構將需要不同的工具進行求解，部份問題則需要參考決策者的偏好關係，對於複雜的決策問題則需要同時結合因果關係與偏好關係的架構。
