【摘要】 以泵站加压输水系统的年费用最低为规划目标,考虑到供水流量随时间的变化过程,建立了确定泵站最优扬程模型、水泵优化选型模型和扬程确定下的输水管优化模型。3个模型分别用线性规划和遗传算法求解。运用这3种模型可得到泵站加压输水系统最优设计方案,这一最优设计方案包括水泵优化选型方案和输水管优化设计方案。更多还原

【Abstract】 According to the planning target of operating a pressurized water delivery system with minimum annual cost in pumping station, and considering the process of water supply discharge varying with time, three optimum models for determining pump station lift head, for pump type selection, and for delivery pipeline when lift head is determined, were proposed in this paper. The three models are derived respectively with the linear programming method and Genetic Algorithms. The three methods are used to obtain the optimum design schemes including optimization of pump type selection and delivery pipeline design for the system.更多还原
