An acknowledged system of systems architecture description method

Large-scale organizations usually perform a mission with several systems with interoperability rather than with a single system. In this paper, we present a System of Systems (SoS) architecture description method which extracts necessary constituent systems from the enterprise architecture repository to achieve the SoS mission objectives. The proposed method can assess the performance and interoperability among the constituent systems in order to know the capability gaps for the mission goals. For a case study, we demonstrate a Missile Defense SoS using the proposed method and algorithms.
