This paper examines the single-commodity network design problem with stochastic edge capacities. We characterize the structures of the optimal designs and compare with the deterministic counterparts. We do this partly to understand what constitutes robust network designs, but also to construct a...

Robustness in Operations Research/Decision Aid is often associated with min–max and min–max regret criteria. This …. Nevertheless, these criteria are known to be too conservative. In this paper, we present and study a new robustness approach …, called lexicographic α-robustness, which compensates for this major drawback and many others. Furthermore, we establish a …

We study a single-commodity Robust Network Design problem (RND) in which an undirected graph with edge costs is given together with a discrete set of balance matrices, representing different supply/demand scenarios. In each scenario, a subset of the nodes is exchanging flow. The goal is to...

The analysis of how to achieve planned economic performance in a real-time, uncertain and perturbed execution environment is a vital and up-to-date issue in many supply chains. Although it is intuitive that uncertainty is likely to have impacts on performance, the research on systematic...
