Abstract
Cyber Physical Systems (CPSs) are the next computing revolution and the
new generation of complex System of Systems (SoSs). CPSs are complex and
ubiquitous embedded devices coupled with global integration respecting Moore’s
Law. Therefore, to fit with their new characteristics, we are facing several
challenges, such as the proliferation and the integration of these systems into
scalable environments.
A main concern of embedded real-time systems is safety. For such safety-critical
systems, not only correct results count, but also the runtime duration for producing
them. To ensure the dependability of such systems, which is not a local property
of the system, but a global system property, the SoS safety has to be assessed,
evaluated and checked according to its specific runtime context.
In an attempt to address the challenges, we propose two domain specific
languages for modeling the system architecture and the dynamic behavior of
heterogenous systems and their interactions. This paper shows how to develop an
approach of real-time system design based on an extension of Milner’s Calculus
Communicating Systems since languages which are based on process algebra
provide suitable features to formalise components communications.
