中文摘要：
针对过去树状管网优化中将管网和管径分步研究，难以实现同步优化的问题，以投资最小为目标，研究了树状管网布置与管径同步优化遗传算法整数编码方法和不同管网布置下水流路径自动识别和压力、流速等约束条件自动计算方法，建立了基于整数遗传算法的树状管网布置与管径同步优化模型．实例研究表明，该方法能将设计经验融合到管网优化之中，可克服传统分步优化方法不易得到全局最优解的缺陷，能快速求解符合工程实际的树状管网布置和管径同步优化方案。同时该方法对其它领域最小生成树问题求解有一定借鉴作用。
英文摘要：
In the tradtional optimization design of tree pipe network, the pipe layout and diameters were optimized step by step,which is dificult to get the global optimization scheme of pipe layout and diameters. In order to overcome this problem, a pipe layout and diameter simultaneous optimization design coding method based on the integer code genetic algorithm was put forward. An automatical method for identifying water flow route of different pipe layouts was deduced, and an automatically calculating program of water pressure of nodes and flow velocity of different pipes was developed. So a pipe layout and diameters simultaneous optimization model and algorithm of tree pipe network was set up. A practical project test results show that the method can conveniently put designers＇ experiences into the course of optimization design of tree pipe network, effectively get global optimization scheme of pipe layout and diameters.
