Infinite Petri Nets: Part 1, Modeling Square Grid Structures

摘要

A composition and analysis technique was developed for investigation of infinite Petri nets with regular structure, introduced for modeling networks, clusters and computing grids, that also concerns cellular automata and biological systems. A case study of a square grid structure composition and analysis is presented. Parametric description of Petri nets, parametric representation of infinite systems for the calculation of place/transition invariants, and solving them in parametric form allowed the invariance proof for infinite Petri net models. Complex deadlocks were disclosed and a possibility of network blocking via ill-intentioned traffic revealed.
