给水管网的计算机辅助优化设计方法

Direct Optimal design Method of Water Network

根据给水管网的水力特性，建立以管段压力及管段流量为求解变量的动态优化计算目标函数，以简约梯度法与罚函数法相结合的优化手段，通过目标函数变换技术，直接解决了求解管径标准化的难题，经实例验证计算效率高，可靠性强．

In accordance with the hydraulic characteristics of water network, this paper advanced the objective function of optimal design regarding pipe flow and pipe pressure as unknown variables. On the basis of specific property of the linear constraints, the obviously effective Reduced Gradient Method was used in the subject. By the transform of objective function, the problem of standardizing diameter was solved successfully. It is proved that the technique is practical with some examples.
