Systems of systems (SoSs) are characterised by a challenging combination of continuous evolution, emergent behaviour and distributed, autonomous, independent constituents. The development of SoSs that can tolerate faults and harmful events is hampered by these and other complexities. Currently there is little in the way of models or tools to help SoS developers to design fault-tolerant SoSs. In this paper we present a structured approach for capturing requirements for a fault-tolerant SoS and a fault modelling architectural framework (FMAF) that supports disciplined and reusable development of fault-tolerant architectures, as well as a traceable mapping of the fault-tolerant requirements into SoS architectural designs. Finally we present an example real-world SoS case study to demonstrate the application of our techniques.
