The concepts of risk aversion, chance-constrained optimization, and robust optimization have developed significantly over the last decade. The statistical learning community has …
Adaptive robust optimization problems are usually solved approximately by restricting the adaptive decisions to simple parametric decision rules. However, the corresponding …

We study policy optimization for the feature-based newsvendor, which seeks an end-to-end policy that renders an explicit mapping from features to ordering decisions. Most existing …
We investigate a simple approximation scheme, based on overlapping linear decision rules, for solving data-driven two-stage distributionally robust optimization problems with the type …
D Bertsimas, C McCord, B Sturt - European Journal of Operational …, 2023 - Elsevier
We develop a tractable and flexible data-driven approach for incorporating side information into multi-stage stochastic programming. The proposed framework uses predictive machine …
Z Chen, M Sim, H Xu - Operations Research, 2019 - pubsonline.informs.org
We consider a distributionally robust optimization problem where the ambiguity set of probability distributions is characterized by a tractable conic representable support set and …
A Pichler, H Xu - Mathematical Programming, 2022 - Springer
This paper considers distributionally robust formulations of a two stage stochastic programming problem with the objective of minimizing a distortion risk of the minimal cost …
We consider stochastic optimization with side information where, prior to decision-making, covariate data are available to inform better decisions. To hedge against data uncertainty …
Y Liu, H Xu, SJS Yang, J Zhang - European Journal of Operational …, 2018 - Elsevier
We develop several distributionally robust equilibrium models, following the recent research surge of robust game theory, in which some or all of the players in the games lack of …
