Purpose: The increase in social awareness, politics and environmental regulation, the scarcity of raw materials and the desired "green" image, are some of the reasons that lead companies to decide for implement processes of Reverse Logistics (RL). At the time when incorporate new RL processes as...

The question we address is how robust solutions react to changes in the uncertainty set. We prove the location of robust solutions with respect to the magnitude of a possible decrease in uncertainty, namely when the uncertainty set shrinks, and convergence of the sequence of robust solutions. In...

District energy systems can not only reduce energy consumption but also set energy supply dispatching schemes according to demand. However, not only the correlation between multiple optimization objectives, but also the time-varying energy demand is ignored when establishing and solving the...
