Abstract: The original Petri nets had some limitations in modelling power and ease of representation. To address these limitations, a new class of extended Petri nets is proposed in this paper. It is called coloured-arc Petri nets (CAPN) because a key feature is the use of colour on the directed arcs. It also makes use of coloured tokens. The main advantage of CAPN over the more general coloured Petri nets (CNP) is that it is not necessary to consult tables to determine the actions of the transition bars.
