Abstract

Systems of systems (SoSs) are particularly vulnerable to faults and other threats to their dependability, but frequently inhabit domains that demand high levels of dependability. For this reason fault tolerance analysis is important in SoS engineering. The COMPASS project has previously proposed a Fault Tolerance Architecture Framework (FMAF), consisting of a collection of viewpoints that support systematic reasoning about faults in an SoS at the architectural level. The FMAF has been demonstrated previously with an analysis of an example fault in an emergency response SoS. In this paper we present further examples of the FMAF’s practical use, by analysing different types of faults drawn from the same emergency response case study. These example faults exercise different aspects of the FMAF, demonstrate its use in more complex fault modelling scenarios, and raise new questions for further development.
