We consider logistic networks in which the control and disturbance inputs
take values in finite sets. We derive a necessary and sufficient condition for
the existence of robustly control invariant (hyperbox) sets. We show that a
stronger version of this condition is sufficient to guarantee robust global
attractivity, and we construct a counterexample demonstrating that it is not
necessary. Being constructive, our proofs of sufficiency allow us to extract
the corresponding robust control laws and to establish the invariance of
certain sets. Finally, we highlight parallels between our results and existing
results in the literature, and we conclude our study with two simple
illustrative examples
