### Abstract

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.

We define PACoR as a Process Algebra ofCommunicating Resources which allows to explicitly expresspreemptiveness, urgentness and resource usage over a dense-timemodel. The semantic interpretation of PACoR is defined in theform of a timed transition system expressing the timed behaviorand dynamic creation of processes. We define a translation ofPACoR systems to Parameterized Stopwatch Automata (PSA).The translation preserves the original semantics of PACoR andenables the verification of PACoR systems using symbolic modelchecking in Uppaal and statistical model checking UppaalSMC.Finally we provide an example to illustrate system specificationin PACoR, translation and verification.
