On Modelling and Analysis of Dynamic Reconfiguration of Dependable Real-Time Systems

This paper motivates the need for a formalism for the modelling and analysis of dynamic reconfiguration of dependable real-time systems. We present requirements that the formalism must meet, and use these to evaluate well-established formalisms and two process algebras that we have been developing, namely, Webπ
_∞
and CCS
^dp
. A simple case study is developed to illustrate the modelling power of these two formalisms. The paper shows how Webπ
_∞
and CCS
^dp
represent a significant step forward in modelling adaptive and dependable real-time systems.
