Evaluation of Resilience of Interconnected Systems Based on Stability Analysis
A modeling framework is proposed to deal with the resilience of interconnected systems. Such systems are regarded as abstract entities subject to mutual functional dependencies. Each system is identified by a node of a directed graph, whose arcs represent such dependencies. In case of malfunction in a node, the failure may propagate to the other nodes with a possible cascading effect. The system behavior under failures is analyzed in a simple case study by using well-established stability tools. Based on such results, metrics of resilience are discussed.
