Robust Two-Stage Network Problemsarc costs are precisely known, and completed optimally in the second stage, after a true second-stage cost scenario occurs. The robust min-max criterion is used to compute an optimal solution. Several complexity results for the interval and discrete uncertainty representations are provided.

Composed Min-Max and Min-Sum Radial Approach to the Emergency System Designhe worst situated user must be considered. Optimization of the average user disutility is often related to the weighted .-median problem. To cope with both objectives, we have suggested a composed method. In the first phase, the disutility of the worst situated user is minimized. The second phase is

LP-Based Relaxations of the Skiving Stock Problem—Improved Upper Bounds for the Gapformulation, different (small) item lengths and corresponding availabilities are given. We aim at maximizing the number of objects with a certain minimum length that can be constructed by connecting the items on hand. Such computations are of high interest in many real world application, e.g. in ind

Creating Worst-Case Instances for Upper and Lower Bounds of the Two-Dimensional Strip Packing Probletrip Packing Problem. The idea of this new approach is to optimise the width and the height of all items aiming to find an instance with maximal performance ratio with respect to the considered heuristic. Therefore, we model the pattern obtained by the heuristic as a solution of an ILP problem and m

The Onset of Congestion in Charging of Electric Vehicles for Proportionally Fair Network Management tly. Such development suggests that a congestion management protocol will be a crucial component of future technological innovations in low voltage networks. An important property of a suitable network capacity management protocol is to balance network efficiency and fairness requirements. Assuming
