Fuzzy Dynamic Petri Nets

Fuzzy dynamic Petri nets model is proposed to process systems with vague information. Different from the traditional fuzzy Petri net systems, we address the Petri nets in the concept of net framework, instead of just a logical prediction system. Formal definition of dynamic Petri nets and its relation matrix description are given. Then, based-on the relation matrix, fuzzy dynamic algorithm is proposed to study the dynamic process. The feasibility and validity of the proposed approach are illustrated through a diagnosis expert system.
