A fuzzy spatial Petri nets

A fuzzy spatial Petri nets (FSPN) was proposed in order to describe spatial fuzzy knowledge and spatial associated effect between places and transitions. By introducing spatial associated factor, fuzzy Petri nets combined with spatial location was researched in depth to solve uncertainty factor associated with environment area and execute dynamic reasoning. Structure and signification of State associated effect component, transition associated effect component and state associated threshold values were set forth in particular according to distributing condition of spatial effect factor. At last, equivalence analysis was done comparing with basis Petri nets and improvement analysis was implemented comparing with fuzzy Petri nets. Using correlative components, spatial knowledge and associated effect with fuzzy associated factor can be effectively represented in practice.
