Structural Transformations Giving B-Equivalent PT-Netsre 80] and we pointed out the interest of the substitution theorem in PT-net analysis [Andre 81-2]. In short, the substitution of a closed subnet by a B-equivalent one doesn’t change the properties (liveness, synchronic relations for transitions; markings for places) on the unmodified part of the net.

EWE

Equivalence Notions for Concurrent Systemsvalence (the sets of possible event sequences are equal), are unuseful for comparing concurrent systems. In fact it has been shown (in (1) by Milner) that two strongly (and then also weakly) equivalent concurrent systems can differ w.r.t. the interactions with some other concurrent system.
