Abstract:

The fresh water consumption, flexibility and complexity of water networks are major considerations when optimal schemes for integrated water networks are determined.A compromise usually needs to be done before the final decision on the optimal schemes could be made because of the nature of multi-objective optimization problem.To evaluate the optimal schemes of water networks quantitatively among these objectives, a quantitative approach was proposed to analyze and evaluate the optimal schemes of water networks based on game theory.The integration of water network with internal water mains was taken as an example.The analyses of the optimal schemes were illustrated by the proposed approach.The results showed that the proposed method was capable of reasonably evaluating the optimal schemes of water networks.It is of significance in the determination of optimal schemes of integrated water networks with multi-objective optimization, and provides an insight into analysis and guidance in determining the optimal schemes of water networks quantitatively.

摘要：

对水系统集成优化方案的分析和决策需要考虑新鲜水用量、用水系统的柔性和用水网络结构的复杂程度等方面。水网络优化设计方案的确定一般需要在这三者之间进行折中和协调，属于多目标优化问题。为了综合考虑新鲜水消耗量和网络结构复杂程度等指标，并定量分析和确定水网络的优化设计方案，本文提出一种基于博弈分析的水网络优化方案的定量分析方法。以具有中间水道水网络优化设计方案的决策为例，采用本文方法进行了优化设计方案的分析与评价。研究表明：该定量分析和评价用水网络的方法可以合理地评价用水网络的设计方案，该方法可用于定量确定水系统优化问题中的多目标优化方案，可为水系统优化集成方案的确定提供分析依据和指导。
