Model checking process algebra of communicating resources for real-time systems

This paper presents a new process algebra, called
PACoR, for real-time systems which deals with resource-
constrained timed behavior as an improved version of the
ACSR algebra. We define PACoR as a Process Algebra of
Communicating Resources which allows to explicitly express
preemptiveness, urgentness and resource usage over a dense-time
model. The semantic interpretation of PACoR is defined in the
form of a timed transition system expressing the timed behavior
and dynamic creation of processes. We define a translation of
PACoR systems to Parameterized Stopwatch Automata (PSA).
The translation preserves the original semantics of PACoR and
enables the verification of PACoR systems using symbolic model
checking in Uppaal and statistical model checking UppaalSMC.
Finally we provide an example to illustrate system specification
in PACoR, translation and verification.
