摘　　要：通过赋予待优化管段两个新的属性:管径等级属性(label)和流量等级属性(level),将优化目标转为寻求各管段两属性的同一化,并以最大、最小管径为约束条件,建立供水管径优化模型。采用最大差值算法求解模型,对标准管径直接进行优化,计算速度快,结果更符合实际情况。All the pipes to be optimized in the urban water supply network were given two new at- tributes, diameter level attribute （label） and flow level attribute （level） , and the target of the optimization became to make the values of the two attributes be the same for every pipe. Besides, the reasonable maximum and minimal pipe diameters were considered as the constraints, and a model for optimization of water supply pipe diameter was established. The biggest difference algorithm method was used to solve the model. The calculation is quick, and the result is in line with the practical situation when the standard pipe diameter is directly optimized.
