While there has been a surge of articles on convergence diagnostic tools for MCMC on continuous stationary distributions and ordinal state spaces, Bayesian c...
BibTeX reference
We investigate geoengineering as a possible substitute for mitigation and adaptation measures to reduce damages from climate change. With the help of an inte...

Air traffic in Europe is predicted to increase considerably over the next decades. In this context, we present a study of the interactions between the costs...
BibTeX reference
The improved primal simplex (IPS) was recently developed by Elhalaloui et al. to take advantage of degeneracy when solving linear programs with the primal si...
BibTeX reference
We consider a dynamic closed-loop supply chain made up of one manufacturer and one retailer, with both players investing in a product recovery program to inc...
BibTeX reference
We revisit the relationship between market power and firms' investment incentives in a noncooperative differential oligopoly game in which firms sell diffe...

This paper focuses on the resolution of the capacitated minimum cost flow problem on a network comprising <i>n</i> nodes and <i>m</i> arcs. We present a met...
BibTeX reference
Remote communities are typically isolated from the main electricity grid and require local generation, most often relying on expensive resources (especially ...
BibTeX reference
Security-constrained optimal power flow (SCOPF) and security-constrained unit commitment (SCUC) problems are necessary tools for system operators for operati...
BibTeX reference
The Mesh Adaptive Direct Search (MADS) algorithm is designed for blackbox optimization problems subject to general inequality constraints. Currently, MADS do...
BibTeX referenceSystem-of-systems approach to air transportation design using nested optimization and direct search
Aircraft sizing, route network design, demand estimation and allocation of aircraft to routes are different facets of the air transportation optimization pro...
BibTeX reference
We introduce an efficient approach to evaluate counterparty risk and compute the Credit Value Adjustement for derivatives having early exercise features. The...
BibTeX reference
We present a matheuristic, an integer programming based heuristic, for the liner shipping network design problem. This problem consists of finding a set of...
BibTeX reference
This paper presents a new method for solving the short-term unit commitment and loading problem of a hydropower system. Dynamic programming is used to comput...
BibTeX reference
The inventory-routing problem (IRP) integrates two well-studied problems, namely, inventory management and vehicle routing. Given a set of customers to servi...
BibTeX reference
Constrained blackbox optimization is a difficult problem, with most approaches coming from the mathematical programming literature. The statistical literatur...
BibTeX reference
Blackbox optimization deals with situations in which the objective function and constraints are typically computed by launching a time-consuming computer ...
