摘要

Li and Zhou propose to add monitors Vs to elementary siphons S only while controlling the rest of dependent siphons - important for large systems but far from being maximally permissive. The control policy for weakly dependent siphons (WDS) is rather conservative due to some negative terms in the controllability. We show that this is no longer true as can be shown that it has the same controllability as that for strongly dependent siphons.
