强语义{P,A}-时间Petri网的交织

On interleaving in {P,A}-Time Petri nets with strong semantics

Hanifa Boucheneb, Kamel Barkaoui

摘要:

在强语义背景下研究了{P,A}-时间Petri网(简称{P,A}-TPN)的可达性分析.它调查的凸性的工会的状态类达到不同的交错的同一套过渡。在BB 08中,作者考虑了T-TPN模型及其收缩状态类图(CSCG),并证明了该并集不一定是凸的。然而,他们建立了一些充分条件,确保凸性。本文证明了对于{P,A}-TPN的CSCG,这个并是凸的,并且可以在不计算中间状态类的情况下计算。这些结果可以提高前向可达性分析凝聚,在相同的状态类,所有的状态类达到不同的交错的同一组转换(抽象凸联盟)。

英文摘要:

This paper deals with the reachability analysis of {P,A}-Time Petri nets ({P,A}-TPN in short) in the context of strong semantics. It investigates the convexity of the union of state classes reached by different interleavings of the same set of transitions. In BB08, the authors have considered the T-TPN model and its Contracted State Class Graph (CSCG) and shown that this union is not necessarily convex. They have however established some sufficient conditions which ensure convexity. This paper shows that for the CSCG of {P,A}-TPN, this union is convex and can be computed without computing intermediate state classes. These results allow to improve the forward reachability analysis by agglomerating, in the same state class, all state classes reached by different interleavings of the same set of transitions (abstraction by convex-union).
