Universal petri net

Abstract

A universal inhibitor Petri net executing an arbitrary given inhibitor Petri net is constructed. An inhibitor Petri net graph, its marking, and transition firing sequence are encoded as 10 scalar nonnegative integer variables and are represented by the corresponding places of the universal net. An algorithm using only these scalar variables and executing an arbitrary inhibitor net is developed based on the state equation and is encoded by the universal inhibitor Petri net. Subnets that implement arithmetic, comparison, and copy operations are employed.
