Abstract

Ensuring resilience – the ability to remain dependable in dynamic environment – constitutes a major challenge for engineering systems-of-systems (SoS). In this paper, we take a mission-centric view on the behaviour of SoS and demonstrate how to formally reason about their dependability. We use Event-B as our modelling framework and demonstrate how to formally specify and verify generic system-wide dependability properties as well as the dynamic behaviour of SoS. The proposed approach is exemplified by a case study – a flight formation system. As a result, we argue that Event-B offers a scalable approach to formal modelling of SoS and facilitates engineering of resilient SoS.
