无冻结令牌的自由选择Petri网与双极同步系统

Free Choice Petri Nets without frozen tokens and Bipolar Synchronization Systems

Joachim Wehler

摘要:

双极同步系统(BP系统)构成了一类有色Petri网,非常适合于离散动态系统的控制流建模。每个BP系统都有一个底层的普通Petri网,它是一个T系统。此外,它还附加了第二个普通网,这是一个自由选择系统。我们证明了BP系统是活的和安全的,如果T系统和自由选择系统是活的和安全的,如果自由选择系统没有冻结令牌。这个结果是Genrich和Thiagarajan的一个定理的逆,并证明了一个老猜想。该证明利用Petri网的态射和自由选择系统的经典理论对不同的Petri网进行了比较

英文摘要:

Bipolar synchronization systems (BP-systems) constitute a class of coloured Petri nets, well suited for modeling the control flow of discrete, dynamical systems. Every BP-system has an underlying ordinary Petri net, which is a T-system. Moreover, it has a second ordinary net attached, which is a free-choice system. We prove that a BP-system is live and safe if the T-system and the free-choice system are live and safe and if the free-choice system has no frozen tokens. This result is the converse of a theorem of Genrich and Thiagarajan and proves an elder conjecture. The proof compares the different Petri nets by Petri net morphisms and makes use of the classical theory of free-choice systems
