摘　　要：以重力水头利用程度作为重力输配水管网优化设计评价的指标,以两种不同形式的重力水头利用率——管段水头利用率和路径水头利用率作为系统优化的目标函数,衡量不同设计方案对地势落差所产生的位置水头的利用程度,对所建立的模型采用具有家族内部和家族之间两层竞争机制的列队竞争算法进行求解计算。结合算例,将该方法与以管网投资最小为目标的遗传算法进行了比较,结果表明本文提出的方法可行,收敛速度较快,且控制参数少。Taking the utilization degree of gravity head, the design＇s utilization rate of pressure drop created by hypsography was evaluated by using two different expressions namely utilization rate of pipe gravity head and utilization rate of path gravity head as network optimization objective functions. Line-up competition algorithm （LCA） with the two means competition that between families and inside a family and little controls parameter was introduced in optimal design. The result testified by the case study, and the comparison between the method based on minimization of cost and genetic algorithm showed that the new method could obtain the optimal result and is superior in search efficiency.
