Incidence Matrix Based Methods for Computing Repetitive Vectors and Siphons of Petri Net

In this paper, the relations among T-invariants, repetitive vectors and siphons are investigated and new methods for computing repetitive vectors and siphons are suggested based on them. The transition-added net of a net is defined and a relation is shown that there always exists a T-invariant of the transition-added net corresponding to a repetitive vector of the original net, and vice versa. Based on this relation, an algorithm that can...
