OPTIMAL DESIGN OF A WATER DISTRIBUTION NETWORK USING SIMULATION–BASED MULTI-OBJECTIVE OPTIMIZATION
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 1
Abstract
The design of water distribution networks is aiming at a good compromise between reliability and costs. Because such networks commonly serve for several objectives, multi-objective optimization approaches are the appropriate methods for this purpose. In this paper, the results of a simulation-based multi-objective optimization (MO-CMAES-EP) approach which couples a multi-objective covariance matrix adaptation evolution strategy (MO-CMA-ES) with Epanet are presented. The new method was tested with two published benchmark cases, the two-loop network and the Hanoi water network. The objective functions used in this study are aiming at the minimization of initial capital cost and maximization of network resilience. The results reveal that MO-CMA-ES-EP is able to determine the true Pareto optimal front of cost and network resilience index which serves as a tool for decision makers of water networks design.
