At first, a superstructure is built up to consider all the possible pipings in a network. A design problem is then formulated into a MINLP problem which considers al constraints. Then extending the water networks to a scheduling problem, developing the design which considers simultaneously the optimal water networks and optimal scheduling. The use of storage tanks will be considered in the examples, in which, cyclic operation and forbidding recycle will be taken into account. The mathematical model for the superstructure is discussed under various situations, such as changing concentration and changing starting time of the unit. Finally, using this MINLP formulation to optimize fresh water in all the situation above mentioned.1 緒論 1 1.1 前言................................................1 1.2 水網路設計之發展說明................................2 1.3 批式與連續製程之比較................................2 1.4 時間表示法..........................................5 1.5 文獻回顧............................................5 1.6 研究動機與目的......................................7 1.7 組織章節............................................8 2 批式製程用水網路最適化之模式結構 11 2.1 模式建立之背景說明..................................11 2.2 模式建立之基本假設條件..............................11 2.3 模式建立之圖解說明..................................14 2.4 模式之符號、系統參數與系統變數 (Indices, Sets, Parameters, and Variables)..........16 2.4.1 指標符號說明(Indices).........................16 2.4.2 集合說明(Sets)................................17 2.4.3 系統參數(Parameters)..........................17 2.4.4 系統變數(Variables)...........................18 2.5 限制式(Constraints).................................20 2.5.1 製程用水單元中流量平衡與溶質平衡(Water/Solute Balances).................................................20 2.5.2 中間儲存槽中流量平衡與溶質平衡(Water/Solute Balances).................................................23 2.5.3 再生再循環水流的排除(Elimination of Regeneration Recycling)...................................25 2.5.4 製程時間規劃(Scheduling)......................27 2.6 目標函數(Objectives)................................28 2.6.1 目標函數(1): 最少的供應水流量(Objective Function(1): Minimum Supply Water)................................28 3 批式製程用水網路最適化設計:情境模擬 29 3.1 最適化軟體..........................................30 3.2 例一之情境模擬......................................30 3.2.1 例一模式之模擬結果分析與討論..................31 3.3 例二之情境模擬......................................36 3.3.1 例二之模擬結果分析與討論......................37 3.4 例三之情境模擬......................................40 3.4.1 例二之模擬結果分析與討論......................41 4 批式製程之排程規劃與用水網路最適化之模式建構 47 4.1 排程模式建立之說明..................................47 4.2 排程模式建立........................................48 4.2.1 目標函數(2):最短的整體操作時間(Objective Function(2): Minimum Operating Time)......................48 4.3 例四之情境模擬......................................49 4.3.1 例四之模擬結果分析與討論......................50 4.4 例五之情境模擬......................................54 4.4.1 例五之模擬結果分析與討論......................55 4.5 例六之情境模擬......................................59 4.5.1 例六之模擬結果分析與討論......................60 5 結論與未來展望 67 5.1 結論................................................67 5.2 未來展望............................................68 參考文獻 69 作者簡歷..................................................732860761 bytesapplication/pdfen-US批式製程用水網路最適化batchwater networkscheduling批式製程用水網路與排程規劃最適化設計之研究Water Networks Design and Scheduling Optimization for Batch Plantsthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/52046/1/ntu-95-R93524058-1.pdf
