Water distribution network robust design based on energy surplus index maximization

摘要: The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure water distribution network reliability, also represent valuable and effective indicator robustness under alternative scenarios. It can thus be profitably used for design conditions uncertain future demands. methodology adopted consisted of: (a) multi-objective optimization performed in order minimize construction costs while maximizing the index; (b) retrospective performance assessment solutions Pareto front obtained, demand far from those assumed during phase. Two case studies different topological complexity were considered. Results showed which one most indices represents well.
