Utility-based shortfall risk measure (SR) effectively captures decision maker’s risk attitude on tail losses by an increasing convex loss function. In this ...

BibTeX referenceThe value of randomized strategies in distributionally robust risk averse network interdiction games

**Erick Delage**

Conditional Value at Risk (CVaR) is widely used to account for the preferences of a risk-averse agent in the extreme loss scenarios. To study the effectiven...

BibTeX referenceAdjustable robust optimization reformulations of two-stage worst-case regret minimization problems

**Erick Delage**

This paper explores the idea that two-stage worst-case regret minimization problems with either objective or right-hand side uncertainty can be reformulated ...

BibTeX reference**Erick Delage**

We consider a class of min-max robust problems in which the functions that need to be *robustified* can be decomposed as the sum of arbitrary functions. This...

**Erick Delage**

Drawing on statistical learning theory, we derive out-of-sample and optimality guarantees about the investment strategy obtained from a regularized portfoli...

BibTeX reference**Erick Delage**, and Jinlin Li

This paper considers a dynamic Emergency Medical Services (EMS) network design problem and introduces two novel two-stage stochastic programming formulatio...

BibTeX referenceThe value of randomized solutions in mixed-integer distributionally robust optimization problems

**Erick Delage**and Ahmed Saif

*Randomized decision making* refers to the process of taking decisions randomly according to the outcome of an independent randomization device such as a dic...

Robust self-scheduling of a price-maker energy storage facility in the New York electricity market

Recent progress in energy storage have contributed to create large-scale storage facilities and to decrease their costs. This may bring economic opportunitie...

BibTeX reference**Erick Delage**, Daniel Kuhn, and Wolfram Wiesemann

Stochastic programming and distributionally robust optimization seek *deterministic* decisions that optimize a risk measure, possibly in view of the most adv...

**Erick Delage**

In this article, we discuss an alternative method for deriving conservative approximation models for two-stage robust optimization problems. The method main...
