Zusammenfassung:Abstract: "Petri Nets gain a great deal of modelling flexibility when using freely structured "individual" tokens (instead of "black dots"). Any kind of data structure and structured objects can be represented this way, together with a formal description of their dynamic change. Algebraic specifications turned out adequate and flexible for dealing with structured objects. We will use this formalism to construct Petri Nets with individual tokens and to formulate corresponding analysis techniques
This calculus makes a couple of issues for such nets tractable as usual in algebriac specifications, e.g. the relationship between syntactical and semantical objects, the note of initial algebras, the canonical extension of assignments to arbitrary terms, etc. Place- and transition-invariants are a useful analysis tool for conventional Petri nets. We derive a corresponding calculus for nets with individual tokens, based on simple term substitution.
