Abstract :
We consider production-distribution systems with buffer and capacity constraints in the presence of uncertain inputs. We deal with the problem of finding a control which drives the buffer levels to a prescribed value. We consider a continuous-time model and show that some important properties hold, which fail in general in the discrete-time case. In particular we show the case in which the operator knows the external input is “equivalent” to the case when such information is not available. Furthermore, a decentralized strategy can be determined. We also show that in the case of network failures the operator does not need to know the current network configuration in order to guarantee the tracking goal as long as a certain necessary and sufficient condition is satisfied
