Model-based resilience in the context of complex socio-technical systems (Keynote)

Kurzfassung

From a technical perspective, resilience focuses on the ability of a system to anticipate and to resist external and internal disruptions and disturbances as well as to recover and to learn from such events. This view led to a new paradigm, i.e. away from the classical design criteria fail-safe towards safe-to-fail systems. The former emphasizes the achievement of reliability by pursuing absolute protection and control of system change, while the latter rather aims at the capacity to recover from hazardous events. This talk will show that both concepts must not be contradicting and can be thought together when developing reliable and resilient systems. Therefore, an introduction into the concept of resilience is given, followed by the discussion of theoretical and practical solutions.
