Abstract. Constraint Handling Rules (CHR) is a declarative rulebased concurrent committed-choice programming language. Petri nets are a well-known formalism for modeling and analysis of concurrent processes. We aim to develop a framework to exploit Petri nets as a tool for the modeling and analysis of CHR programs. In this paper, we show that place/transition nets can easily be embedded into CHR and we develop a translation of a significant segment of CHR into coloured Petri nets (CPN).
