Looped Water Distribution System Optimization for Single Loading

Abstract

An optimization algorithm employing a nonlinear programming technique (Davidon‐Fletcher‐Powell method) has been developed for the design of large real‐life urban water‐distribution systems for a single loading. Using the decomposition principle, the NP‐hard problem has been solved by iterative and interactive application of the solutions for analysis and optimization problems, thereby minimizing the number of decision variables. The efficacy of the algorithm has been demonstrated through a case study.
