近年來隨著全球電子產業的快速發展，對半導體的需求不斷增加，同時全球暖化問題日益嚴重，各國政府與企業意識到環境和氣候變化導致自然資源消耗的問題，因此開始提出各種政策來重視永續發展。許多企業開始注重產品的回收和再製，期望能同時提升經濟利益並減輕對環境的負擔。在永續發展的理念下，近年來碳排放議題越來越受到企業和消費者的關注。本研究以此為出發點，將目前半導體產業供應鏈中遇到的問題轉換成數學模型，模型中包含一間晶圓製造商以及兩間競爭關係之化學液供應商並將碳排放納入製造商的成本中考量，由供應鏈成員的獲利與環境角度為出發點，探討不同的生產策略在何種條件下會被採用、其效益為何及如何影響成員間的互動。
本研究假設市場中存在單一製造商與兩競爭關係之供應商，分別為模型一： 兩供應商價格競爭且新進供應商進行再製造；模型二：兩供應商價格競爭且新進供應商進行再製造並將再製品銷售至二級市場(secondary market)。藉由賽局理論(game theory)決定決策順序，求得供應商產品價格、再製造製程中半成品的品質、製造商對價格的敏感度、市場需求使利潤最大化，最後再對結果進行數值分析，檢視各參數對決策變數、需求及利潤的影響。
研究結果發現，再製化學液作為實現永續發展的可行解決方案，透過合作不僅能降低生產成本，還能減少對環境的不良影響，有助於促進技術創新和資 源節約。對於新進供應商而言，應根據市場需求調整供應範圍，以提高競爭力並確保客戶滿意度。綜上所述，本研究發現供應商與製造商合作的重要性，並提出再製化學液作為促進永續發展的解決方案，從而實現環境保護和經濟發展 的雙贏。

In light of continually advancing technology and the surge of environmental awareness, the negative environmental impacts generated from the production process and logistics are increasingly being acknowledged. In this thesis, mathematical models have been built in composed of a semiconductor wafer manufacturer and two competing chemical liquid suppliers. In addition, the impact on the supply chain under different production models on the supply chain from both profitability and environmental perspectives. According to the varying levels of acceptance of remanufactured products by manufacturers, we developed two distinct supply chain models. The analyses showed that remanufacturing can indeed serve as a viable solution for achieving sustainable development. Through collaboration, it not only reduces production costs but also mitigates adverse environmental impacts.
