This paper introduces the consistent vehicle routing problem with stochastic customers and demands. We consider driver consistency as customer-driver assignm...

We study an integrated multi-product production and distribution problem considering a network of multiple plants and customers, who are geographically dispe...

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

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...

We consider an integrated optimization problem including the production, inventory, and outbound transportation decisions where a central plant fulfills the ...

It is well known that the integrated optimization of multiple and inter-related decisions in a supply chain can bring important benefits to companies. In thi...

The standard blending problem consists of combining components to produce a final product with a given demand, while satisfying specific criteria with resp...

We propose a generalized decomposition approach for production planning problems with process configuration decisions. These problems appear in contexts wher...

Dealing with demand uncertainty in multi-item lot sizing problems poses huge challenges due to the inherent complexity. The resulting stochastic formulation...

Nous étudions un problème stochastique de planification de production et réapprovision-nement sur trois échelons via un processus de décision en deux étapes....

We study an integrated process configuration, lot-sizing, and scheduling problem, which appears in a real production environment in the packaging industry. P...

Nous étudions un problème intégré de planification de production et de transport sur trois niveaux avec une structure de distribution (3LSPD), problème qui e...

We consider an integrated planning problem that combines production, inventory and inbound transportation decisions in a context where several suppliers each...

While the joint optimization of production and outbound distribution decisions in a manufacturing context has been intensively studied in the past decade, th...

Two-level orthogonal designs play an important role in industrial screening experiments, in which the primary goal is to identify the treatment factors with ...

Nous étudions ici l'impact des contraintes de niveaux de service dans le contexte des problèmes de planification de production avec ou sans contrainte de cap...

We study the Capacity Constrained Lot Size Problem with Setup Times (CLST). Based on two strong reformulations of the problem, we present a transformed refor...

Dantzig-Wolfe reformulation solved by Column Generation is an approach to obtain improved bounds for Mixed Integer Programs. A downside of this approach is t...

The production routing problem (PRP) concerns the production and distribution of a single product from a production plant to multiple customers using capacit...

The inventory routing problem (IRP) and the production routing problem (PRP) are two difficult problems arising in the planning of integrated supply chains...

The Job Grouping Problem consists of assigning a set of jobs, each with a specific set of tool requirements, to machines with a limited tool capacity in orde...

Operational problems arising in the planning of integrated supply chains have been increasingly studied in the past decade. Among these, the production rout...

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

In this paper, we generalize the Asymmetric Representatives Formulation, which was first introduced by Campêlo et al. (2008) for the Node Coloring Problem. ...
