In this paper, we propose an extension of Petri nets (LC-Petri net: LCPN) suitable for FMS design and discuss its methods of evaluation. This LCPN is a marked net with addition of the following features: data assignment of marks, representation of firing conditions as logic equations, coupling of output procedures with transition firing, etc. Also, since the concept of transition firing evaluation orders is omitted from the analysis of conventional Petri nets, we introduce this concept formally in our proposed net. Finally, in order to study the behavior of a system modelled with this net, we provide a means for searching the reachability tree of markings. This LCPN is a extended Petri nets which solve a problem of description from Place/Transition Petri nets and Colored Petri nets before.
