應用數學規劃法作跨廠區水網路之最適化設計

近年來，由於水資源的短缺，以及人類對於環境和永續發展議題的重視，工業用水整合已然成為相當活躍的研究領域。本論文旨在以數學規劃法探討跨廠區水網路合成之問題；所謂的跨廠區水網路包含廠區間水資源再利用之可能性。在此前提下，數個廠區內外之用水整合將同時考慮。另外，此論文提出一個不同的跨廠區製程用水整合方案，係透過中央及分散式儲存槽的配置以減低單元之間相互的擾動，同時提高系統操作之彈性。此外中央儲存槽的使用更有利於處理廠區間的水資源分配，透過合併相同目的地之水流，有效地減少管線成本並簡化水網路的結構。本研究以超結構為基礎建立數學模式，並利用此數學模式分析兩種不同的目標函數（最小純淨水用量及最小年總成本），再將跨廠區整合之結果與不使用儲存槽及各廠區分開設計之情況比較，以突顯此一新的整合模式之立基。

This thesis presents a mathematical model for the inter-plant water integration of an industrial complex that consists of a number of process plants. Opportunities for water reuse/recycle across plants are exploited. In particular, a novel integration scheme is proposed, where central and decentralized water mains are placed to interconnect different plants and various process units within individual plants, respectively. The main advantage of using these water mains is to enhance network practicability. The model formulation is based on superstructures, and the system is designed according to two objectives including the minimization of fresh water consumption and total annualized cost. An example is solved to illustrate the proposed scheme and approach.
