Szukana fraza: [Abstract = "The first enhancement considers chance\-constraint programming to compute an optimal inventory replenishment policy based on a desired risk acceptability level, leading to dynamical allocation of safety stocks in flow\-based networks to satisfy non\-stationary flow demands. The second enhancement computes a smart distribution of the control effort and maximises actuators` availability by estimating their degradation and reliability. The proposed approach is illustrated with an application of water transport networks using the Barcelona network as the case study considered."]
