Research on resilient systems extends classical system analysis, modeling and simulation approaches. Of interest are system architectures and behaviors that are capable of dealing with partial, major or complete system damage in such a way that the intended overall system performance is recovered very fast. Examples for systems include infrastructure grids, critical infrastructure, communication networks, organizational structures, societal structures and their respective technical support. Examples for partial system damage are power grid interruptions due to terror attacks, or effects of earthquakes on urban infrastructure. Hence research on resilient systems will contribute to avoid and mitigate crisis effects as well as to improve crisis prevention and shorten recovery times. The concept of resilience goes beyond reliability by redundancy or reliability by design. It allows for dynamic reconfiguration, resulting in systems that may differ from the original systems. Further it asks for the analysis of a large system trajectory/evolution space and measures for assessing the system reconfiguration options and performance. The time scales of coupled systems under analysis may be very different, also typically very different disciplines are involved, asking for flexible and scalable system analysis, modeling and simulation. Resilient systems are allowed to fail partially, thus allowing for optimized overall performance taking system operation as well as recovery costs into account. Along with the technical research questions of defining, analyzing, modeling, simulating, testing and validating resilient systems societal needs and requirements are expected to drive and determine research options. For instance the level of reconfiguration or the partial loss of system performance must be subject to public involvement, discussion and assessment.
