在降雨時空分佈不均下，台灣水資源供應不穩定，為了確保用水無虞、維持正常生產已儼然成為高科技產業重要之挑戰，而為了提高水資源的回收再利用及水的利用效率，政府早已訂定嚴格之各項回收標準已及輔導廠商進行水回收的規劃。然而目前產業多半是使用經驗法則來規劃水資源的回收策略，但卻鮮少利用數學模式，計算出最大的節水量。本研究旨在透過線性規劃法，針對最小用水成本及最小碳放兩目標進行模式設立及求解。當自來水水價提升50%時，將促成回收水單元Ⅰ、Ⅱ之回收量增加10.5%，最後並歸納出工業的節水策略及建議。 As uneven distribution of rainfall, the water supply in Taiwan is unstable. Thus, Maintaining normal production have become an important challenge in the high-technology industry. To improve the efficiency of water reuse and recycle in water resources, government has defined stringent recycle standards and provided counsel of water recovery planning. However, recycle water planning strategy has been frequently used in current industry, which mathematical models is rarely used to calculate the maximum amount of water saving. The aim of this study is using linear programming to design models and solution for minimum water cost and minimum carbon emission. When the water supply cost increased by 50 %, the water recovery unit (i,ii) would lead the recovered amount increased by 10.5 %. The water-saving strategies and recommendations also conclude in this study.
