Construction and Application of Learning Petri Net

چکیده
Petri nets are excellent networks which have great characteristics of combining a welldefined mathematical theory with a graphical representation of the dynamic behavior of systems. The theoretical aspect of Petri nets allows precise modeling and analysis of system behavior, at the same time, the graphical representation of Petri nets enable visualization of state changes of the modeled system [32]. Therefore, Petri nets are recognized as one of the most adequate and sound tool for description and analysis of concurrent, asynchronous and distributed dynamical system. However, the traditional Petri nets do not have learning capability. Therefore, all the parameters which describe the characteristics of the system need to be set individually and empirically when the dynamic system is modeled. Fuzzy Petri net (FPN) combined Petri nets approach with fuzzy theory is a powerful modeling tool for fuzzy production rules-based knowledge systems. However, it is lack of learning mechanism. That is the significant weakness while modeling uncertain knowledge systems.
