摘要

Water distribution system (WDS) design has received much attention lately from the point of viewnof uncertainties. Designers are generally interested in the Pareto optimal cost-robustness tradenoff curve. This paper aims to find a solution to the multiobjective problem in a computationallyntime-efficient way in comparison to previous methods from the literature. A parameter u, which isnlinked to the system robustness through a derived analytic formula, is introduced. The robustnessnof the WDS can be approximated by one single model simulation; consequently a large amount ofncomputational time is saved compared to using a sampling-based technique. The application ofnthe method to the New York tunnels problem demonstrates that, although the resulting designnis conservative on cost, the proposed method is very computationally efficient. This is ofnimportance when high computational cost is the major obstacle for some real-world problems.
