Abstract: Simulation Nets (SNs) are Petri Nets extended for convenient modelling of discrete event simulation problems. Experience from modelling and simulation by two interpreting tools suggest that more modelling power is needed. The nets have to be extended in several ways. In this paper we concentrate on the extension of the tokens. The typed (colored) tokens in SNs, which can carry data, but not make full use of it, will be extended into object-oriented tokens. These can contain more subtle data and rules, for a more active participation in the control structure of the net.
