【Abstract】 Proceeding from view of overall optimum and minimum water cost for water distribution systems,and considering practical characteristic of production for water supplying systems,optimum schedule model for complex water distribution systems are presented. Genetic algorithms are used to solve the optimum schedule model,then code regular, chromosome evaluation and genetic operation are deeply studied,furthermore solution steps for optimum control are given in detail.Matlab is adopted to write optimum schedule program based on genetic algorithms,and the program is applied to simulate production schedule for certain city water distribution systems.Simulation result shows that overall optimum solution is 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.更多还原
