Abstract: For the purpose of modeling Discrete Event Systems (DES), a Petri net-based modeling framework called Dan/Petri Net (D/PN) is presented, working only with subnets and having a different enabling rule based on an arcs-counting function and non-boolean guards called dans. And Controlled D/PN is one extension developed to explain the modeling of multiple and simultaneous control (MSC) in DES through the fundamental MSC subnet and its notation convention, called valid MSC subnet c(q) and its derivative subnet na(q). At the end of this paper we present the usage of Controlled D/PN in the MSC design for an D/PN model through MSC subnets.
