    L’organisation virtuelle en réseau
    (Presses de l'Université Laval, 2000-10-11) Poulin, Diane; Montreuil, Benoit; D'Amours, Sophie
    Pour survivre, l’entreprise, quelle qu’elle soit, petite ou grande, doit aujourd’hui comptersur une grande capacité d’innovation fondée sur une maîtrise du changement technologique, une souplesse de fonctionnement qui lui permet de réagir sur-le-champ aux fluctuations de ses marchés et la mobilisation de ses ressources humaines, rassemblées autour d’un projet commun. Elle doit constamment apprendre à apprendre, se remettre en question, ne rien prendre pour acquis si elle veut faire face aux nouvelles réalités industrielles et commerciales.

    Prise en compte des contraintes législatives dans la planification des ressources
    (Institut National des Sciences Appliquées, 2006) Kane, Hamdjatou; Ait Kadi, Daoud; Baptiste, Pierre; D'Amours, Sophie
    Dans ce papier, nous fraitons de la problématique de planification des ressources dans un contexte d’aménagement du temps de travail (cas de la France). En effet, le cadre législatif actuel introduit de nouveaux leviers de décision (annualisation) mais, en même temps, contraint fortement leur utilisation. Dans ces conditions, les changements fréquents du niveau de personnel opéré jusqu’ici pour répondre aux.fluctuations de la demande ne sont admis que sous certaines conditions. Nous proposons une étude qualitative sur la planification des ressources en utilisant les heures annualisées, les heures supplémentaires et les heures intérims pour répondre au besoin de flexibilité de la capacité.

    Conception des réseaux logistiques : mesure de fiabilité et planification d'accélérateurs
    (International conference on logistics research, 2000) Cavory, Guillaume; Frayret, Jean-Marc; D'Amours, Sophie
    Dans le domaine de la production manufacturière, il est maintenant largement reconnu que l'unité compétitive dépasse l'entreprise pour se concentrer sur l'ensemble du réseau logistique. Ainsi, les entreprises ne sont plus directement en compétition entre elles, mais plutôt par l'intermédiaire des divers réseaux logistiques auxquelles elles appartiennent, impliquant ainsi chaque relation client-fournisseur depuis le fournisseur du fournisseur jusqu'au client du client. De plus en plus de travaux de recherche se concentrent sur l'amélioration de la performance globale des réseaux de production et de distribution à travers le concepts de supply chain management. Dans le cadre de cette problématique, cet article présente dans un premier temps le contexte industriel, puis un ensemble de travaux sur la mesure de la fiabilité des réseaux manufacturiers et logistiques, suivi de l'amélioration de la fiabilité de ces réseaux par des mécanismes d'accélération, puis finalement de l'apport de la simulation dans l'évaluation de la fiabilité. Cet article se terminera par la présentation d'un exemple de réseau manufacturier. La fiabilité que nous étudions ici concerne les retards de livraison ainsi que le respect des volumes livrés.

    Collaborative order management in distributed manufacturing
    (Taylor and Francis, 2007-02-21) Montreuil, Benoit; Abid, Chafik; D'Amours, Sophie
    The construction of a decision assistant tool for order management is outlined. Given a factory, which has a certain capacity to satisfy a certain number of orders, the objective is to assign each order to a specific period, thus maximizing the level of customers' satisfaction. The optimization algorithm supports the sales department and forms an interface between customers' needs and the production system. By combining advances in information technology and optimization technology, a method is presented based on collaborative planning techniques that optimizes customer satisfaction as well as resource utilization. For this purpose, an algorithm was developed based on an integer program model. The tool was implemented using the Java programming environment and Cplex optimization software. The proposed model takes the form of an agent, evolving within a multi-agent system. The proposed algorithm is compared with the greedy heuristic used by the world-class motorcoach manufacturer for which this research was conducted. Computational results show that the agent-based method proposed outperformed a heuristic method currently used in industry.

    Impact of benefit sharing among companies in the implantation of a collaborative transportation system : an application in the furniture industry
    (Springer, 2008-01-01) Audy, Jean-François.; D'Amours, Sophie
    Transportation has become an increasingly important part of the Canadian furniture industry supply chain. Even when different furniture companies ship to the same regions, the same cities and/or the same furniture retailers, coordination between two or more companies is rare. Recently, interest in collaborative transportation planning to support coordination has intensified as important potential benefits (e.g. cost and delivery time reductions) have been identified. Even though substantial benefits can be realized, the methods for sharing benefits among companies as well as the leadership of the collaboration implementation are key issues in deciding on a logistics scenario for the collaboration. In this paper, the impacts of these two key issues are illustrated using an industrial case study of four Canadian furniture companies shipping to the United-States.

    Business models for collaborative planning in transportation : an application to wood products
    (Association for information systems, 2006) Rönnqvist, Mikael; Audy, Jean-François.; D'Amours, Sophie
    In this paper, we propose a framework to describe collaboration in transportation. Then, we discuss the strategic, tactical, operational and real-time transportation planning decisions and raise issues about implementing collaborative decision processes. Also, we provide a literature review of transport decision-support systems that use collaborative planning in the wood fiber flow chain in forestry. Finally, we propose a typology of different business models associated with collaboration in transport.

    E-business in the Quebec forest products industry : perceptions, current uses and intentions to adopt
    (Research Consortium in e-Business in the Forest Products Industry (FOR@C), 2005-08-01) Frayret, Jean-Marc; Karuranga, Égide; D'Amours, Sophie
    This paper proposes an analysis of e-business, its perceptions, current uses, and the intentions of companies to adopt these practices in the Quebec forest products industry. We use the results of an exploratory survey of this industry carried out during spring 2002. In accordance with other surveys, it is shown that despite its location in a country where information technology (IT) adoption level is generally high, the Quebec forest products industry still lags behind other sectors. The e-business uses of the surveyed companies in the Quebec forest products industry value chain are explored by category; year of establishment, number of employees and annual revenue. Actors surveyed include sawmills, other value added building material manufacturers, furniture factories, and pulp and paper mills. Perceptions, currents uses, and intentions of adoption are described with a comparison to the same industry in North America. In particular, this paper demonstrates that this industry somewhat lacks a strategic vision concerning the exploitation of IT tools. Finally, this paper proposes a critical review of the limitations of our study and develops future research directions.

    Motivations for multi behavior agents in supply chain planning
    (Édition Tec & doc-Lavoisier, 2008-01-01) Frayret, Jean-Marc; Gaudreault, Jonathan; Forget, Pascal; D'Amours, Sophie
    In today’ industrial context competitiveness is closely associated to supply chain performance. Coordiantion between production partners is essential in supply chains to deliver products on time to final clients. As perturbations occur all the time, production centers have to react quickly correct deviances and create new plans, while coordinating changes with partners. Agent-based technology provides a natural approach to model supply chain networks and describe specialized planning agents. To coordinate and optimize their production plan, agents ue specify the heuristic parameters a priori, at the time of their design and prior to their use. The solution proposed here is to give agents the opportunity to change these parameters, modifying their planning behaviors following the environmental conditions met. Using simulation, agents can identify optimal team behaviors for the supply chain in different situations. This paper explains the methodology followed to experiment multi-behavior agents and presents results from an application to the lumber supply chain.

    Study of social consciousness in stochastic agent based simulations : application to supply chains
    (Association for Computing Machinery, 2006-05-08) Moyaux, Thierry; D'Amours, Sophie; Chaib-Draa, Brahim
    Empirical game theory allows studying the strategic interactions of agents in simulations. Specifically, traditional game theory describes such interactions by an analytical model, while empirical game theory employs simulations. In this paper, we use empirical game theory to study how the moreor-less selfishness of agents affects their behaviour. To this end, we assume that every agent utility can be split in two parts, a first part representing the direct utility of agents and a second part representing agent social consciousness, i.e., their impact on the rest of the multiagent system. An application to supply chains illustrates this approach. In this application, the collaborative strategy is often used by every company-agent at whatever their same level of social consciousness, which may indicate that every agent is strongly related with one other.
