Empirical Comparison of Unified Benders Cuts for Multi-Commodity Fixed-Charge Network Design
Eric Larsen, Jean-François Cordeau, Antonio Frangioni +1
Among the many types of acceleration techniques designed to improve the performance of Benders decomposition, unified cut generation schemes have recently attracted a keen interest…
Relative Explanations for Contextual Problems with Endogenous Uncertainty: An Application to Competitive Facility Location
Jasone RamÃrez-Ayerbe, Emma Frejinger
In this paper, we consider a contextual stochastic optimization problem in which unknown parameters follow distributions that depend on contextual covariates and decisions. The pro…
Contextual Preference Distribution Learning
Benjamin Hudson, Laurent Charlin, Emma Frejinger
Decision-making problems often feature uncertainty stemming from heterogeneous and context-dependent human preferences. To address this, we propose a sequential learning-and-optimi…
Arc travel time and path choice model estimation subsumed
Sobhan Mohammadpour, Emma Frejinger
We address the problem of simultaneously estimating arc travel times in a network \emph{and} parameters of route choice models for strategic and tactical network planning purposes.…
The Intermodal Railroad Blocking and Railcar Fleet-Management Planning Problem
Julie Kienzle, Serge Bisaillon, Teodor Gabriel Crainic +1
Rail is a cost-effective and relatively low-emission mode for transporting intermodal containers over long distances. This paper addresses tactical planning of intermodal railroad…
A Capacitated Collection-and-Delivery-Point Location Problem with Random Utility Maximizing Customers
David Pinzon Ulloa, Ammar Metnani, Emma Frejinger
We consider a strategic decision-making problem where a logistics provider (LP) seeks to locate collection and delivery points (CDPs) with the objective to reduce total logistics c…
