基于水源-水阱匹配关系约束的用水网络优化方法

以水源-水阱匹配关系为约束条件，建立了单杂质用水网络的混合整数线性规划模型。提出了通过逐步调整水源与水阱匹配关系矩阵，把混合整数线性规划问题转化成多步的线性规划问题的求解策略。本文提出的优化方法，在最小新鲜水用量相同的条件下，能设计出水源与水阱匹配关系数少，流程结构简单、投资成本少的水网络。应用两个实例说明了本文方法的有效性。

Optimal design of water network based on water source-sink matching constraint

The mixed integer linear programming model was established with the water source-sink matching as the constraint. To solve this model, the matrix of the source and sink matching was gradually adjusted, and the mixed-integer programming problem was transformed into a multi-step linear programming problem. The optimization method proposed in this paper, under the same conditions of the minimum amount of fresh water, was able to obtain a better water-using network with fewer matches, simpler structure and less...
