管网连通可靠度分析及其应用

Reliability Analysis and Application of Pipe Network Connectivity

结合图论的知识,将实际管网系统简化为点线相连的网络模型,利用网络实时递推算法计算源点与汇点的连通率,得出管网系统各边的连通可靠度和重要性指标,为管网系统科学评估和规划提供依据。对上海市某区管网设施进行管线系统网络重要性分析,证明了该方法的实用性和适用性。

Using graph theory knowledge, the actual pipe network system is simplified as a point-line connected network model. For providing the basis for evaluation and planning of pipe network system, the real-time recursive algorithm of the network is adopted to calculate the connectivity of source points and sink points, as well as the connectivity reliability and importance degree of the pipe network system. In addition, the importance of the pipeline system network in a district of Shanghai is analyzed, which proves the practicality and applicability of the method.
