Identification of Critical Nodes in Water Distribution Networks

Abstract

In this work, the problem of the identification of critical nodes in water distribution networks (WDNs) is investigated. A scheme is then put forward to identify critical nodes in WDNs. Mathematical formulations for the scheme put forward are provided in this work. Results show that the application of the scheme yields consistent outputs when applied to the various WDNs test cases. Furthermore, critical nodes could be ranked in order of their criticality based on the sensitivity index.
