A system of systems (SoS) is a large-scale integrated system. In an SoS, many complex independent systems work collectively for a common mission. Modeling of SoS is challenging due to their large-scale and complexity of the constituent systems. In this paper, generic modeling of a class of SoS, namely mechatronic systems, is proposed based on bond graph modeling approach. Bond graph modeling enables to develop a unified model of SoS, which combines the behavioral and the organizational modeling approaches of SoS. The proposed approach for SoS modeling is applied to intelligent transportation system, where road traffic dynamic in a platoon of intelligent autonomous vehicles (IAVs) is considered for modeling. Finally, the developed bond graph model is simulated for a platoon of four IAVs forming SoS.
