摘　　要：长距离输水管道已成为保证城市供水可靠性和安全性的重要途径.以树状重力输水管网的线性规划模型为基础,分别应用单纯形法、遗传算法及其组合算法进行了长距离输水管道系统的优化设计.研究表明,遗传算法和线性规划法的联合应用可为长距离输水管道系统的优化设计提供一种可行而有效的新方法,既可以充分利用遗传算法的全局寻优能力,又能利用线性规划法获得一组具有标准管径的最优管长组合方案,可为方案评估提供多种可供选择的优化方案.The long-distance water transmission pipelines have become the main way to ensure the reliability and safety of water supply for urban areas.Based on the linear programming model of gravity tree pipe network,the optimal design of long-distance water transmission pipelines have been achieved by the simplex method,genetic algorithms and their commbined methods.The applicaitons show that the compositively application of genetic algorithms and linear programming can provide a feasible and effective new mothed for the optimal design of long-distance water transmission pipelines.It not only can make full use of the global optimization capability of genetic algorithms,but also can use the linear programming method to find a group of optimal design solutions with optimal length combinations of standard diameters.The proposed methods can provide many kinds of optimal design solutions for assessment.
