The effective heat - transfer temperature difference ( t _ i ) of every effect of multi - effect evaporation subsystem and the preheat temperature rise ( t _ ( p, j ) ) of every level of multi - level preheat subsystem of the design model were distributed by equal heating area, equal heat - transfer temperature difference, and free proration methods. the simulation of design has been conducted by matrix method combined with iterative method. the free proration method transformed the decision variables from t _ i and t _ ( p, j ) with complex restriction into _ i 、 _ p, jwith the value range of 0 1, and provided a simple and convenient method for optimum design
操作型模型分別以t _ 0 、 t _ k 、處理量f _ 0 、出料濃度x _ （ az ）等不同控制變量為未知變量並採用矩陣法結合迭代法進行操作模擬計算;在操作模擬計算的基礎上，建立了復雜多效蒸發系統操作優化模型，該模型以濃縮成本最小為優化目標，以t _ k和f _ 0為決策變量，採用遺傳演算法結合矩陣法求解。 -
