In view of the overall optimization of water supply network system and the minimum water supply cost, a mathematical model of the overall optimal operation of complex water supply system is established according to the production scheduling characteristics of complex water supply system.The mathematical model is solved by genetic algorithm with multi-dimensional code, , Chromosomal evaluation and genetic manipulation were studied in detail and a detailed solution procedure was given.An optimized scheduling program based on genetic algorithm was programmed by Matlab software.The production scheduling of a water distribution network in a city was simulated. The simulation results show that genetic algorithm can solve the optimal scheduling of pipe network system and get the global optimal solution of the problem. Compared with the actual production of the water company, the optimal cost can be saved by using the optimal scheduling program.
