Résumé:
Petri nets are widely used to design a liveness-enforcing Petri net super-
visor for deadlock prevention in a
exible manufacturing system. A monitor-based su-
pervisor performs better, i.e., with more permissive behavior, if its monitors are well
designed. Deadlock control policies developed by max-controlled siphons are shown to be
overly conservative from permissive behavior points of view. On the basis of the concept
of max'-controlled siphons, this paper provides three methods, from structural points of
view, to design monitors for siphons in S4R nets, systems of simple sequential processes
with shared resources. A deadlock prevention policy is developed accordingly, leading to
liveness-enforcing Petri net supervisors with more permissive behavior. The proposed
approaches and algorithm are then illustrated through an example.
