Towards an object-oriented modeling language for probabalistic open distributed systems

In this paper, we propose a probabilistic extension of the Creol modeling language, called PCreol, for which we give the operational semantics in Probabilistic Rewrite Logic. We give details on the implementation of a prototype PCreol interpreter, executable in Maude, on top of the existing one for Creol. We also achieved the integration of PCreol with the VeStA tool, which allows for statistical model checking and statistical quantitative analysis of PCreol programs. We give two example PCreol programs and show how VeStA can be used to study their properties. The paper is concluded with a number of future research directions
