The presence of symmetry is common in certain types of scheduling problems. Symmetry can occur when one is scheduling a collection of jobs on multiple identi...

Le vieillissement de la population a mis l'accent sur les systèmes publics de retraite dans la plupart des pays développés. Pour éviter que les déficits de l...

This study proposes a game theoretic approach toward the analysis of renewable portfolio standard policy (RPS), which is one of the main forces behind prom...

The production-routing problem can be seen as a combination of two well known combinatorial optimization problems: the lotsizing and the vehicle routing prob...

Advanced discrete choice models, such as parametric/non-parametric mixed logit and hybrid choice models, are heavily used in travel behavior research. The...

La plupart des compagnies distribuant de l’huile de chauffage résolvent des problèmes de tournées de véhicules presque quotidiennement. Ces problèmes peuven...

The role of the Information and Communication Technology sector on productivity and economic growth is constantly increasing and, due to its pervasiveness, ...

The <i>positive edge</i> is a new pricing rule for the primal simplex: it identifies, with a probability error less than or equal to 2^-30 in sing...

In the rail industry, profit maximization relies heavily on the integration of logistics activities with an improved management of revenues. The operational ...

In this paper, we empirically investigate the robustness of random forests for regression problems. We also investigate the performance of five variations o...

In this paper we study the capacitated team orienteering problem where split deliveries are allowed. A set of potential customers is given, each associated w...

In this paper, we empirically compare open-loop and closed-loop investment strategies in production capacities in the three-player Finnish electricity indust...

It is seldom the case that one has the opportunity to compare investments as projected by a long-term multi-period model to what is eventually realized in pr...

We revisit the question of why some participants in online auctions place their bids right before the time of closing. Using e-Bay data for two product cate...

This paper presents an extension of the well known random forest method to the case of clustered data. The proposed "mixed effects random forest" method is i...

Optimization of single machine, single part-type dedicated Kanban policies in multi-part transfer lines with unreliable machines is considered. At each prod...

This paper deals with an application of dynamic games for the design of efficient climate policies involving both adaptation and mitigation elements. More pr...

The computational intractability of the dynamic programming (DP) equations associated with optimal admission and routing in stochastic loss networks of any n...

Paleoclimate evidence and climate models indicate that certain elements of the climate system may exhibit thresholds, with small changes in greenhouse gas em...

Normalized cut is one of the most popular graph clustering criteria. The main approaches proposed for its resolution are spectral clustering methods (e.g. [1...
