Application Research on Multidimensional Code Genetic Algorithms for Optimum Control of City Water Distribution System

Proceeding from view of overall optimum and minimum water cost for water distribution systems,and considering practical characteristic of production for water supplying systems,genetic algorithms for optimum control of complex water distribution systems were presented,then code rule,chromosome evaluation and genetic operation were deeply studied,furthermore solution steps for optimum control were given in detail.Matlab software was adopted to write optimum control program based on genetic algorithms,and the program was applied to simulate production control for certain city water distribution systems.The result shows that overall optimum solution is able to obtained when genetic algorithms are used to optimum control of complex water distribution systems,and that production control by optimum control program contributes to economize water-supply cost.2figs.,1tab.,11refs.
