| Abstract: | Process of Petri nets can present the concurrent semantic of Petri nets,which is an effective way for analyzing and verifying the Petri net properties.This paper studies the relationship between process expression and liveness of bounded Petri nets,and provides theorems of liveness determination for bounded Petri nets and their synchronous composition nets.The paper also explores the relationship between process expressions and traps and siphons. |
