Abstract

In this paper, we undertake to enhance a general framework for the modeling and validation of real-time concurrent systems which is known as ATC (Actors with Temporal Constraints). To prove that a given system is a valid implementation of its specification, one is often led to decide whether two systems behave in the same manner with respect to a given equivalence relation. In that connection, we propose equivalence relations between systems expressed within the ATC model. As a timed extension of the Actor model, ATC inherits all the functional capabilities of actors and further allows for the expression of most of the temporal constraints pertaining to real-time systems: exceptions, delays and emergencies.
