Hardness of robust network design

The authors settle the complexity status of the robust network design problem in undirected graphs. The fact that the flow-cut gap in general graphs can be large, poses some difficulty in establishing a hardness result. Instead, the authors introduce a single-source version of the problem where the flow-cut gap is known to be one. They then show that this restricted problem is coNP-Hard. This v...

A ROBUST OPTIMIZATION MODEL FOR BLOOD SUPPLY CHAIN NETWORK DESIGN

The eternal need for humans' blood as a critical commodity makes the healthcare systems attempt to provide efficient blood supply chains (BSCs) by which the requirements are satisfied at the maximum level. To have an efficient supply of blood, an appropriate planning for blood supply chain is a challenge which requires more attention. In this paper, we address a mixed integer linear programming...

Approximation and hardness results for Robust Network design with Exponential Scenarios

In a classical optimization problem, we are usually given a system with some known parameters and constraints and the goal is to find a feasible solution of minimum cost (or maximum profit) with respect to the constraints. Often these parameters and constraints, which heavily influence the optimum solution, are assumed to be precisely known. For example, we might be given a graph G(V,E) with we...

Robust Network Design

Robust network design takes the very successful framework of robust optimization and applies it to the area of network design, motivated by applications in communication networks. The main premise is that demands across the network are not fixed, but are variable or uncertain. However, they are known to fall within a prescribed uncertainty set. Our solution must have sufficient capacity to rout...

Robust network design

A crucial assumption in many network design problems is that of knowing the traffic demands in advance. Unfortunately, measuring and predicting traffic demands are difficult problems. Moreover, often communication patterns change over time, and therefore we are not given a single static traffic demand, but instead a set of non-simultaneous traffic demands. The network should be able to support ...
