Isfahan University of Technology Department of Civil Engineering Optimization of Water Distribution Networks using Genetic Algorithm and Fuzzy Logic By Mahsa Amirabdollahian Supervisors Dr M R Chamani Dr K Asghari Abstract This thesis considers the critical problem of the design and optimization of Water Distribution Systems WDS As the first step Genetic Algorithm GA as an evolutionary algorithm is used in order to design the optimal WDS and then Fuzzy reasoning is introduced to evaluate the penalty function for each potential solution Optimal design of a WDS under multi loading condition is another point which is considered in this thesis Calculating the fitness function for each flow distribution and then adding all the results leads to a design of a network which operates satisfactory in all loading conditions regarding to hydraulic criteria In the last step the optimal design of a network using Genetic Fuzzy algorithm GFA is considered The constrains are introduced individually by Fuzzy membership functions and maximizing operator is used to obtain a single number as penalty part of fitness function The model is applied to two well known examples to benchmark the results The first WDS has eight pipes arranged in two loops and is fed by gravity In this problem the decision variables are pipe diameters and the optimization problem is constrained by maximum and minimum pressures in nodes and maximum and minimum flow velocities in pipes In the GA
