| 摘 要： | 将多目标进化算法与启发式算法相接合,对供水管网微观模型进行优化调度研究.目标函数为供水系统的运行费用和维护费用最小化,以及水压服务水平的最大化(保证安全供水),以各泵站各型号水泵的开启和调速泵的转数比为决策变量,进行二进制-实数混合编码,并采用新型的交叉算子.运用NSGA-Ⅱ、epsilon-MOEA、SPEA2三种多目标进化方法求解优化运行模型,并通过工程算例进行比较.应用表明,多目标进化算法能为供水系统的优化决策提供支持.

| Abstract: | Multiobjective evolutionary algorithms(MOEAs) combined with a developed heuristic algorithm are used to solve the optimal operation problem in micro water supply system.This work has two objectives to be minimized:operation cost,maintenance cost,and one objective to be maximized:service level of hydraulic.Decision variables are the settings of the pumps and speeds of variable-speed pumps at each time step of the total operational time horizon.A mixed coding methodology and a new crossover operator are devel... |
