Abstract:

In recent years, redundant sensing has gained attention as a means to improve the resilience of autonomous cyber-physical systems (CPS). Resilience, however, has not been stringently defined. In this work, a standard-based understanding of resilience was derived, resulting in 11 properties that contribute to resilience. This understanding was used to analyse literature on autonomous CPS, their domains, operating environments, and the disruptions they encounter. A subsequent analysis shows a prevalence of measures acting during the disruption, while anticipating or learning measures are scarce.
