建立了以管网投资和运行费用最小、管网水力可靠性和管网熵值可靠性最大为目标的供水管网优化模型。结合模型的特点,在基本混合蛙跳算法的基础上,提出两点改进措施,并将改进的混合蛙跳算法用于供水管网优化模型的求解。最后通过天津市规划供水管网的实例,验证了改进的混合蛙跳算法能够用于求解大规模管网优化问题并具有较高的效率。
A water supply network optimization model is established with the goal of minimizing the investment and running cost of the pipe network, maximizing the reliability of the pipe network and maximizing the entropy of the pipe network. Combining with the characteristics of the model, two improved measures are proposed based on the basic mixed leapfrog algorithm. The improved hybrid frog leaping algorithm is used to solve the optimal model of water supply network. Finally, through the example of planning water supply network in Tianjin City, it is verified that the improved hybrid frog leaping algorithm can be used to solve large-scale pipe network optimization problems with high efficiency.
