摘　　要：从供水管网系统整体优化和最小供水费用的角度出发,结合复杂供水系统的生产调度特点,建立了复杂供水系统整体优化调度的数学模型.利用多维编码的遗传算法求解数学模型,对其编码规则、染色体的评估以及遗传操作进行了深入的研究.并给出了详细的求解步骤.采用Matlab软件编写了基于遗传算法的优化调度程序.对某市供水管网系统的生产调度进行了仿真研究.仿真结果表明,应用遗传算法求解管网系统优化调度,可以得到问题的全局最优解,并将调度结果和自来水公司实际生产情况比较,采用优化调度程序进行生产调度可以节省运行费用.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.
