Small world network analysis on fault propagation characteristics of water networks in eco industrial parks
Abstract Water network failures in eco industrial parks (EIPs) are often caused due to the spread of a fault from a small fault source. Therefore, it is necessary to investigate failure propagation characteristics to ensure the safety and stability of operations. This paper presents the fault propagation characteristics of water networks in EIPs. First, a water network model of an EIP is constructed based on the theory of small world network. Second, the degree and betweenness centrality of nodes are used to identify the high load nodes of water networks. The fault nodes are assumed to be the ones affecting the effluent quality nodes. According to the ant colony algorithm, the failure propagation paths with the highest risk are found by fault attack and maximum load attack, respectively. The illustrated cases show that the proposed method can find weak links of water networks, which provides a basis for fault prevention, selection of key monitoring variables, and risk assessment.
