基于复杂网络理论的城市供排水系统规划优化

Optimization of Urban Water System Planning Based on Complex Network Theory

基于复杂网络理论,研究城市水系统中关于设施布局和节点重要性问题,簇系数可以表征城市水系统中重要设施的空间布局情况,该值越小表示空间布局越合理。城市水系统中的节点度值表征了该节点的重要程度,通过对高度值节点的梳理,可以形成城市管网系统重要节点的分布,从而为主干管网系统的布置提供依据。将该方法应用于某典型案例城市,从多个规划方案中推荐运行效率更优的方案,实现了城市水系统规划的优化。

Based on complex network theory,the problems of facility layout and node importance in urban water system were explored.Cluster coefficient can represent the spatial layout of important facilities in urban water system,and the smaller the value is,the more reasonable the spatial layout is.Degree of the node in urban water system represents the importance of the node.By combing the high degree nodes,distribution of the important nodes in urban pipe network system can be formed,which provides a reference for the layout of the main pipe network system.Through the application of this method in the case cities,the scheme with better operational efficiency among multiple planning schemes was recommended,and thus the optimization of urban water system planning was realized.
