Architecting System of Systems for Resilience using MBSE

With rapid growth in the interconnectivity and interdependency among systems to deliver diverse set of capabilities, the challenge of architecting such System of Systems is becoming more complex, more so with the rapid evolution of technologies. To ease the involved complexity and challenges of System of Systems Engineering (SoSE), this paper summarizes the proposed approach and methodology for conducting architecture analysis of System of Systems (SoS) for resilience, and for assessing the SoS architectures qualitatively and quantitatively for the maturity level of resilience, using Model Based Systems Engineering (MBSE) as a support. The approach has been arrived at based on a taxonomy of principles that enable resilience in an architecture. Unified Architecture Framework (UAF) is used as a reference for defining the architecture principles, which can be utilized for defining the architecture in MBSE. The Search and Rescue sample model of SoS in UAF Plugin of Cameo Systems Modeler has been both augmented and assessed using the proposed methodology and architecture principles.
