A Novel Approach to Analyze the Isolation Valve System Based on the Complex Network Theory

Complex Network Theory (CNT) studies network models and centrality metrics to deal with reliability/vulnerability assessment in networked systems. Classic CNT analyses evaluate the impact of failure single vertices/edge elements on system connectivity assuming that all vertices/nodes have same relevance. In Water Distribution Networks (WDNs), Isolation Valve System (IVS) plays a crucial role for reliability because pipe asks valves shutdown isolate pipe, usually requiring isolation larger segment, having its intrinsic This circumstance makes classic misleading WDN. work proposes novel approach analyze IVS, which is based construction graph segments generated by IVS. The application recently proposed relevance-based (WDN-tailored) betweenness such used rank importance valves. Two WDNs different sizes are demonstrate discuss strategy also from practical perspective.
