供水管网优化模型比较研究

A comparative study on optimal models of water supply network

以寻找工程实践中最可行的管网优化模型为目的,通过理论分析和实例计算对工程中常用的单目标线性规划模型、多目标线性规划模型和单目标非线性规划模型进行对比研究。结果表明,单目标非线性规划模型具备较强实用价值。三类模型的比较研究也为进一步改进管网优化设计方法提供了新的思路。

A comparison study on three kinds of mathematical model, namely, single-objective linear programming model, multi- objective linear programming model and single-objective nonlinear programming model is made based on the related theoretical analysis and the case studies, so as to find out the optimum model in the engineering practiee concerned. The result shows that the single-objective nonlinear programming model has more practical applicable value. Furthermore, this study also provides a new concept for the further improvement on the optimal design methods of the water supply networks.
