This paper concerns control of stochastic networks using state-dependent safety-stocks. Three examples are considered: a pair of tandem queues; a simple routing model; and the Dai-Wang re-entrant line. In each case, a single policy is proposed that is independent of network load ρ • . The following conclusions are obtained for the controlled network in each case, where the finite constant K 0 is independent of load: The policy is fluid-scale asymptotically optimal, and approximatelydoi:10.1109/cdc.2004.1429357 fatcat:3ynwnrba5nbbheaf45vy5klyqu
