In this paper, we study a distributionally robust multi-item newsvendor problem, where the demand distribution is unknown but specified with a general event-...

Une fonction de coût de Mayer constante par morceaux est requise pour correctement modéliser des problèmes de contrôle optimal dans lesquels l'espace des éta...

L'utilisation de l'espace par les satellites est de plus en plus importante pour les nations, les entreprises et les particuliers. Cependant, depuis l'envoi ...

We introduce an iterative method named GPMR for solving 2X2 block unsymmetric linear systems. GPMR is based on a new process that reduces simultaneously...

This paper presents an efficient method for extracting the second-order sensitivities from a system of implicit nonlinear equations. We design a custom aut...

Production yield can be highly volatile and uncertain, especially in industries where exogenous and environmental factors such as the climate or raw material...

Pour un graphe simple et connexe \(G\), soient \(D(G), ~Tr(G)\), \(D^{L}(G)=Tr(G)-D(G)\), et \(D^{Q}(G)=Tr(G)+D(G)\) la matrice des distances, la mat...

A small polygon is a polygon of unit diameter. The maximal area of a small polygon with \(n=2m\) vertices is not known when \(m \ge 7\). In this paper, w...

Le Dixième atelier de résolution de problèmes industriels de Montréal, qui eut lieu du 13 au 27 août 2020, fut organisé conjointement par le Centre de recher...

Pour un graphe \(G\), la matrice du laplacien sans signe \(Q(G)\) esf définie comme \(Q(G) = D(G) + A(G)\), o`u \(A(G)\) est la matrice d'adjacence ...

This paper studies a stochastic variant of the vehicle routing problem (VRP) where both customer locations and demands are uncertain. In particular, potentia...

This paper introduces the consistent production routing problem in a setting with multiple plants and products. The problem consists in finding minimum-cost ...

We propose a tone-based event study to reveal the aggregate abnormal tone dynamics in media articles around earnings announcements. We test whether they co...

We study bin-packing and lot-sizing decisions in an integrated way. Such a problem appears in several manufacturing settings where items first need to be cu...

Nous étudions la stabilité des accords environnementaux internationaux portant sur une cible commune pour le niveau d'émissions polluantes. En signant l'ac...

The increasingly complex energy systems are turning the attention towards model-free control approaches such as reinforcement learning (RL). This work propos...

A small polygon is a polygon of unit diameter. The maximal width of an equilateral small polygon with \(n=2^s\) vertices is not known when \(s \ge 3\). T...

Battery charging of electric vehicles (EVs) needs to be properly coordinated by electricity producers to maintain the network reliability. In this paper, we ...

Binary quadratic programming (BQP) is a class of combinatorial optimization problems comprising binary variables, quadratic objective functions and linear/no...

This paper aims to identify the sources of value created in the strategic plan of a mining complex when the adaptive simultaneous stochastic optimization of ...
