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.
