System of Systems Challenges

Abstract

The available technology (e.g., the Internet) makes it possible to interconnect independently developed embedded systems (legacy systems) to form new system-of-systems ({SoS)} that promise more efficient economic processes and improved services. Examples of {SoSs} are smart power distribution, car-to-car communication, or air-traffic control. The different subsystems of an {SoS} are developed according to their unique architectural style, are operated by different organization and serve their own purposes. The integration of the subsystems into an {SoS} can be static or dynamic. The emergent properties that come into existence by the integration of the subsystems can be predicted or are, at first, unforeseen. There a number of unique challenges in the design of system of systems such as, for example: the alignment of the diverse architectural styles, the control of the emergent properties, information security, and the provision of dependable service in the face of the continuous evolution of the subsystems. This talk will elaborate on the characteristics of {SoS} and will focus on the mentioned research challenges that must be tackled in order to provide dependable {SoS} services.
