It is well known that each tree metric <i>M</i> has a unique realization as a tree, and that this realization minimizes the total length of the edges among ...

The Holt-Klee Condition states that there exist at least <i>d</i> vertex-disjoint strictly monotone paths from the source to the sink of a polytopal digraph ...

This paper examines the plant location problem under the objective of maximizing return-on-investment. However, in place of the standard assumption that all...

Column generation is one of the most successful approaches for solving large scale linear programming problems. However, degeneracy difficulties and long-ta...

Column generation has become a powerful tool in solving large scale integer programs. It is well known that most of the often reported compatibility issues ...

Deheuvels (1981a,b,c) and Genest and Rémillard (2004) have shown that powerful rank tests of multivariate independence can be based on combinations of asymp...

The multivariate modelling of default risk is a crucial aspect of the pricing of credit derivative products referencing a portfolio of underlying assets, an...

Deheuvels proposed a rank test of independence based on a Cramér–von Mises functional of the empirical copula process. Using a general result on the asympto...

Rank-based estimators were proposed by Clayton (1978) and Oakes (1982) for the association parameter in the bivariate gamma frailty model. The joint asympto...

Several upper bounds on the largest Laplacian eigenvalue of a graph <i>G</i>, in terms of degree and average degree of neighbors of its vertices, have been ...

The AutoGraphiX (AGX) system for computer assisted or, for some of its functions, fully automated graph theory was developed at GERAD, Montreal since 1997. ...

This is the last part of a four-part survey of optimization models and solution algorithms for winter road maintenance planning. The two first parts of the ...

Winter road maintenance planning involves a variety of decision-making problems related to the routing of vehicles for spreading chemicals and abrasives, fo...

This paper considers a shift scheduling problem that includes different forms of flexibility in terms of shift starting times, break lengths and break plac...

This paper presents and assesses a procedure to estimate conventional parameters characterizing fluctuations at the business cycle frequency, when the econ...

This paper deals with the control of stochastic nonlinear hybrid systems. Under some appropriate assumptions results on stochastic stability and stochastic...

Une étude du transport de roses coupées, en collaboration avec la plantation Mira- flores évalue l’exportation de Bogotá (Colombie) vers Miami (USA), port d...

La localisation d'un site d'approvisionnement pour minimiser les coûts d'opérations est une problématique industrielle courante. Les variables classiques co...

In order to study the conditions for a world self-enforcing agreement on climate change, we model cooperative and non-cooperative world climate strategies w...

Moody's KMV method is a popular commercial implementation of the structural credit risk model pioneered by Merton (1974). It is an algorithm for estimating...
