Description:
Process modeling by Petri bets is still very broad and applicable. Lots of various modifications and enlargements are arising. One of these enlargements is Fuzzy Petri net, which allows us to do simulations even with vague values. In following article we will concentrate on data storing of Petri nets and Fuzzy Petri nets. The base is found on broad XML and its modification for Petri net PNML. In second part of this article we will describe the application of Fuzzy Petri nets and outline the possibility of PNML enlargement of fuzzy items. This enlargement allows easier implementation into current systems.
