Аннотация
In this paper we present an approach for modelling and analyzing flexible
manufacturing systems (FMSs) using Petri nets. In this approach,
we first build a Petri net model (PNM) of the given FMS in a bottom-up
fashion and then analyze important qualitative aspects of FMS behaviour
such as existence/absence of deadlocks and buffer overflows. The
basis for our approach is a theorem we state and prove for computing
the invariants of the union of a finite number of Petri nets when
the invariants of the individual nets are known. We illustrate our
approach using two typical manufacturing systems: an automated transfer
line and a simple FMS.
