- Abstract:
- Based on the idea of multi-objective optimization, a coordinated design method of water distribution network considering economy, resilience and water quality was proposed. Firstly, a multi-objective design mathematical model of water distribution network was established by taking total cost (including construction and operational costs), network resilience index and water age as optimal objectives under satisfying multiple loading (instantaneous peak, average day demand, multiple fire events) and constraint conditions. Then, the optimal model was solved by using auto-adaptive multi-objective evolutionary algorithm (Borg), and Pareto optimal solution set was obtained. Finally, rationality of the proposed coordinated design method was verified in the Anytown network by comparing with the optimal results of those based on NSGA-Ⅱ as well as only considering cost and resilience. The above coordinated design method can not only reveal the trade-off between cost, resilience and water quality, but also significantly improve the water quality of water distribution network while satisfying various conditions, so as to provide decision-makers with design solutions of better overall benefits.
