Optimal design of water distribution networks via particle swarm optimization

Abstract

In this paper, the mathematical models of two water distribution network systems, namely a Serial Network and a Branched Network have been considered as nonlinear optimization problems and Particle Swarm Optimization (PSO) method has been used to obtain the global optimal solution in each case. The PSO is a heuristic optimization method. Herein, the PSO has been used to determine the minimum cost of the water distribution network system for a Serial Network and Branched Network. The numerical results indicate the robustness of the PSO method. It suggests that PSO method can be effectively used for any generalized water distribution network system. ©2008 IEEE.
