Abstract: The S-composition logic Petri nets are defined based on Petri nets and logic Petri nets in this paper. How to preserve the liveness of S-composition logic Petri nets is deeply investigated, and the theorems and algorithms of judging the liveness of S-composition logic Petri nets are given. Resource sharing in S-composition logic Petri nets is analyzed. Finally, a method of liveness inheritance is presented by adding control places, since there is resource competition in S-composition logic Petri nets.

Key words: logic Petri net, S-composition, liveness, resource sharing, liveness inheritance

摘要: 基于Petri网和逻辑Petri网,提出了S-组合逻辑Petri网的概念。深入研究了S-组合逻辑Petri网的活性继承问题,给出了S-组合逻辑Petri网活性的判定定理和算法,并分析了S-组合网中几种资源共享情况。针对组合逻辑Petri网的几种资源共享情况,提出了相应的利用控制库所实现S-组合逻辑Petri网活性控制的方法。
