Resilience Indexes for Water Distribution Network Design: A Performance Analysis Under Demand Uncertainty

摘要: Traditionally, the optimal design of water distrubution networks has been dealt with using single-objective constrained approaches, where aim is to minimize network investment cost while maintaining minimum pressure head constraints at all nodes. However, in last decade some authors have proposed multi-objective approaches which optimize other objectives than cost. In most cases, these formulated concept resilience index, mimics providing excess above allowable nodes and designing reliable loops practicable pipe diameters. Although several different indexes for this pupose, date there no empirical study that analyzes advantages disadvantages proposals. This paper evaluates performance a well-known evolutionary algorithm, Strength Pareto Evolutionary Algorithm 2, three indexes. The results obtained two supply under large number simulated over-demand scenarios show measures.
