A Markovian Approach for Cross-Category Complementarity in Choice Modeling
Omar El Housni, Shuo Sun, Rajan Udwani
While single-purchase choice models have been widely studied in assortment optimization, customers in modern retail and e-commerce environments often purchase multiple items across…
Assortment Optimization with Visibility Constraints
Theo Barre, Omar El Housni, Marouane Ibn Brahim +2
Motivated by applications in e-retail and online advertising, we study the problem of assortment optimization under visibility constraints, that we refer to as APV. Here, we are gi…
On the Power of Static Assignment Policies for Robust Facility Location Problems
Omar El Housni, Vineet Goyal, David Shmoys
We consider a two-stage robust facility location problem on a metric under an uncertain demand. The decision-maker needs to decide on the (integral) units of supply for each facili…
On the Optimality of Affine Policies for Budgeted Uncertainty Sets
Omar El Housni, Vineet Goyal
In this paper, we study the performance of affine policies for two-stage adjustable robust optimization problem with fixed recourse and uncertain right hand side belonging to a bud…
A Tractable Approach for designing Piecewise Affine Policies in Two-stage Adjustable Robust Optimization
Aharon Ben-Tal, Omar El Housni, Vineet Goyal
We consider the problem of designing piecewise affine policies for two-stage adjustable robust linear optimization problems under right-hand side uncertainty. It is well known that…
