“…This is the cutting of the logs into smaller pieces that are then used in industrial processing. Due to its impact on the final product, and because it is an irreversible process, good planning should be performed, preferably integrated into the remainder supply chain planning (Dems et al, 2013).…”

Aim of study: This work aims to provide an overview of Model Predictive Controllers (MPC) applications in supply chains, to describe the forest-based supply chain and to analyse the potential use and benefits of MPC in a case study concerning a biomass supply chain.Area of study: The proposed methods are being applied to a company located in Finland.Material and methods: Supply chains are complex systems where actions and partners’ coordination influence the whole system performance. The increase of competitiveness and need of quick responses to the costumers implies the use of efficient management techniques. The control theory, particularly MPC, has been successfully used as a supply chain management tool. MPC is able to deal with dynamic interactions between the partners and to globally optimize the supply chain performance in the presence of disturbances. However, as far as is authors’ knowledge, there are no applications of this methodology in the forest-based supply chains. This work proposes a control architecture to improve the performance of the forest supply chain. The controller is based on prediction models which are able to simulate the system and deal with disturbances.Main results: The preliminary results enable to evaluate the impacts of disturbances in the supply chain. Thus, it is possible to react beforehand, controlling the schedules and tasks’ allocation, or alert the planning level in order to generate a new plan.Research highlights: Overview of MPC applications in supply chains; forest-based supply chain description; case study presentation: wood biomass supply chain for energy production; MPC architecture proposal to decrease the operation times.Keywords: biomass; forest; Model Predictive Control; planning; supply chain.

“…However, few models of WPPP including bucking decisions have been reported in the field of wood procurement planning. Dems et al [7] proposed an annual procurement plan that incorporates bucking and transportation activities. The problem addressed in this paper presented a mono-periodic plan that did not deal with variability of the demand and supply according to time periods and did not consider the harvest scheduling decisions, these issues are taken into account in the problem we address in this paper.…”

In this article, we present a wood procurement problem that arises in Eastern Canada. We solve a multi-period wood supply planning problem, while taking into account bucking decisions. Furthermore, we present a new form of flexibility which allows the harvesting capacity to change from one time period to another. We study the impact of such flexibility upon the harvesting cost. We assess the performance of the problem by comparing it with a variant where the harvesting capacity is fixed during sites' harvesting. To address this problem, we develop a hybrid approach based on both constraint and mathematical programming. In the first phase, we propose a constraint programming model dealing with forest sites harvesting and bucking problems. The result of this model is used as part of an initial solution for the whole problem formulated as a mixed integer model. We test the two versions of the problem on a set of different demand instances and we compare their results.

Ce document constitue la conclusion d'un long projet, n'ayant pu être mené et aboutir dans de bonnes conditions que grâce à l'engagement de nombreuses personnes que je tiens à saluer ici.Je remercie en premier lieu Hind Bril El-Haouzi et Philippe Thomas pour leur forte implication dans la direction de cette thèse, de l'écriture du sujet à la soutenance. C'était une chance d'avoir des encadrants aussi accessibles et disponibles, que ce soit pour échanger des idées et des pistes de recherche, relire et corriger documents et présentations, ou simplement discuter et s'aérer l'esprit. Pour tout cela, merci.Evidemment, je tiens à remercier les membres du jury : Pr. Nathalie Julien et Pr. Jonathan Weber, pour avoir acccepté de rapporter cette thèse, ainsi que Pr. Samir Lamouri et Pr. Robert Pellerin pour avoir accepté d'en être examinateurs. Je suis heureux que vous ayez accepté de consacrer votre temps à l'évaluation de mes travaux et d'avoir pu bénéficier de vos différents retours.Tout mes remerciements à Emmanuel Zimmermann, pour son implication et son soutient technique et moral à de nombreuses thèses du site du CRAN d'Epinal. Je remercie également Michael Morin et Jonathan Gaudreault pour nos différentes collaborations qui furent très agréables.Et enfin, pêle-mêle, je remercie (et félicite !) ma famille, mes amis, et mes collègues, pour m'avoir supporter tout au long de ce projet. Discussions, soirées, jeux de société, vacances et voyages : toutes ces choses permettent de garder à l'esprit qu'il y a une vie en dehors du doctorat et qu'il est important de garder un équilibre entre la recherche et les loisirs.
