abstract = {This paper describes a new Petri net model named approximate Petri net. Approximate Petri nets can be used for knowledge representation and approximate reasoning. The net model presented in the paper is defined on the base of the rough set theory, fuzzy Petri nets and coloured Petri nets.},
