English abstract:
Most of today's machines, e.g., automotive engines, production machinery
or even consumer devices, such as a washing machine, are controlled by an embedded
computer system. It is assumed that the widespread integration of these existing
embedded computer systems and data bases into systems-of-systems will provide new
synergistic services, make better use of the available information, lead to new insights,
improve current economic processes and thus create greater wealth. Fueled by the
dramatic technological progress in the area of wire-bound and wire-less communication,
this integration is already happening on a wide scale in industry. From the
viewpoint of computer science, the domain of Systems-of-Systems (SoS) is a relatively
new eld that poses signi cant new research challenges. The table below characterizes
a system of system by listing some distinguishing properties of a SoS compared to
those of a monolithic system. If we look at this table we see that the listed characteristics
of a SoS violate many of the fundamental assumptions that are taken for
granted in the established monolithic system design process. For example, there is
no central development authority, xed speci cation, coordinated evolution, or nal
acceptance test of a SoS. In our view, the most di erentiating characteristics of a
SoS compared to a monolithic system are the autonomy of the constituent systems
(CS) and their means to represent information, emergent phenomena at the SoS level
and uncoordinated evolution of the CSs. From the perspective of a SoS the CSs that
form an SoS are independent, tightly integrated in their local environments and must
be continually adapted to remain relevant to their ever-changing local environments.
On October 1, 2013 the new European FP7 research project AMADEOS (Architecture
for Multi-criticality Agile Dependable Evolutionary Open System-of- Systems)
has started with the following objectives: It is the objective of this research proposal
to bring time awareness and evolution into the design of System-of-Systems (SoS),
to establish a sound conceptual model, a generic architectural framework and a design
methodology, supported by some prototype tools, for the modeling, development
and evolution of time-sensitive SoSs with possible emergent behaviors. The proposed
open and agile architecture will focus on mixed-criticality Cyber- Physical Systems
(CPS) with guaranteed responsiveness. This presentation will focus on the research
issues that are posed by the integration of embedded systems into systems of systems
and will present the research approach taken in the AMADEOS project. The
project is supported by the European Commission under grant agreement 610535.
