    Methodology for assessing collaboration strategies and incentives in the pulp and paper industry
    (Springer, 2011) Lehoux, Nadia; D'Amours, Sophie; Langevin, André
    Under current economic conditions, several companies have decided to implement collaborations with their suppliers, distributors, and retailers, in order to share products and information efficiently as well as reduce their operational costs. Even traditional industries such as the forest industry are now seeking for new business relationships to outperform the competition. In this article, we propose a case study of collaboration between a pulp and paper producer and a wholesaler. In particular, we describe a methodology used to compare different collaborative approaches. We show that this methodology is useful to take multiple operational parameters and constraints into account, as well as to update planning decisions over time. We also discuss the different results obtained for the case study. We demonstrate that collaborative approaches such as CPFR and VMI may reduce network costs, but the savings obtained with these strategies must be distributed fairly. Furthermore, we analyze the use of several incentives to increase the value and strength of the collaboration.

    Generic mechanisms for coordinating operations and sharing financial benefits in collaborative logistics
    (Springer, 2010-01-01) Rönnqvist, Mikael; Lehoux, Nadia; Audy, Jean-François.; D'Amours, Sophie
    Collaborative logistics is increasingly emerging as a new opportunity for cost reduction through internal and cross chains coordination. This paper presents different coordination mechanisms to support collaborative logistics. These mechanisms are differentiated by their planning function, their sharing approach and the information, decision and financial flows. Often, the logistics planning is run first, and secondly, the sharing is set on the basis of the plan. However, recently, new approaches have been proposed where both the logistics plan and the sharing are optimized simultaneously. Constraints on the financial flows also introduce specificities to the coordination mechanisms and these are described and discussed. Finally, the proposed coordination mechanisms are used to describe a series of research and applied projects in which collaborative logistics has been implemented.

    Main motivations and barriers for using wood in multi-story and non-residential construction projects
    (Dept. of Wood and Paper Science, College of Natural Resources, North Carolina State University, 2016-11-01) Gosselin, Annie; Lehoux, Nadia; Cimon, Yan; Blanchet, Pierre
    Steel and concrete are traditionally used as structural materials for non-residential and multi-housing buildings. However, wood can meet the same structural property requirements, and a variety of multi-story buildings have recently been built all over the world using this key material. In this study, the main motivations and barriers to wood adoption for structural uses in non-residential buildings are highlighted, based on an analysis of grey literature concerning some well-known buildings and on scientific literature. The motivations found were linked to sustainability, lack of expertise, costs, rapidity of erection, and aesthetic of wooden structures. In contrast, the barriers preventing its use encompass building code implementation, technology transfer, costs, material durability and other technical aspects, culture of the industry, and material availability. Furthermore, an analysis of non-residential timber building meeting minutes for nine projects is also presented to support the identification of problems and concerns related to site assembly issues, the conception of the building, the scheduling, and stakeholders’ relationships. With a better understanding of the expectations and challenges concerning wood usage in non-residential construction projects, companies will be able to adapt their business models and use the resource even more in the future to develop innovative structures.

    Collaboration enables innovative timber structure adoption in construction
    (MDPI AG, 2018-12-19) Gosselin, Annie; Lehoux, Nadia; Cimon, Yan; Blanchet, Pierre
    Timber structures in construction have become more popular in recent years. Nevertheless, besides the complexity of designing, contracting and building these structures, a barrier to their market growth is the complexity of their supply chain relationships encompassing architects, engineers, builders and suppliers. The objective of this study is therefore to identify and characterize the supply chain relationships shared by these stakeholders within a massive timber construction project. Twenty-seven semi-structured interviews with architects, structural engineers, builders and timber element suppliers from nine countries, participant observations and secondary data were used to study the various relationship levels involved in timber construction projects. Triangulation and qualitative data analysis were also conducted. Three levels of relationships were then identified: “Contractual,” “Massive timber construction project” and “Massive timber construction industry development.” Results showed that timber structures involve value-added stakeholder relationships rather than linear relationships. These relationships appeared closer and more frequent and involved knowledge and information sharing. Furthermore, prefabricated systems allow for smoother relationships by limiting the number of stakeholders while promoting innovative thinking.

    Supply chain modelling frameworks for forest products industry : a systematic literature review
    (Centre interuniversitaire de recherche sur les réseaux d'entreprise, la logistique et le transport, 2014-02-01) Vahid, Saba; Frayret, Jean-Marc; Lehoux, Nadia; Santa-Eulalia, Luis-Antonio; D'Amours, Sophie; Venkatadri, U. $q (Uday)
    Considering the economic importance of forest products industries in Canada, there has been an increasing interest in studying the operations and interactions of all the relevant entities involved in its supply chain (SC). The forest products industry has a set of specific SC characteristics to meet the needs of its final consumers. While a growing number of mathematical and simulation models are being presented for the SC in this sector, an integrated formal structure is evidently required for guiding the development of and evaluating these models. Therefore, in this research, we systematically review and identify existing frameworks for modelling SCs with the interest of highlighting the ones relevant to the forest products SCs. While we find no framework specific to the forest products industry, we identify a number of existing frameworks that could be customized to represent the industry's SC.

    A win-win collaboration approach for a two-echelon supply chain : a case study in the pulp and paper industry
    (Inderscience, 2010-10-04) Lehoux, Nadia; D'Amours, Sophie; Langevin, André
    Because of international competition, the development of new technologies and the increase of production and energy costs, enterprises must improve their supply chains and change their ways of doing business. They also have to collaborate with their suppliers, distributors and retailers in order to better respond to market demand. This kind of relationship can be based on well-known collaboration models like collaborative, planning, forecasting and replenishment (CPFR) or vendor managed inventory (VMI), so as to correctly exchange products and information. However, it is necessary to choose the right collaboration approach that will be profitable for all partners. In this article, we study different collaboration strategies between a pulp and paper producer and its retailer. For this particular context, we identify the collaboration mode that is the most profitable for each actor, based on real costs and parameters obtained from the industrial case. We also develop a method to better share collaboration benefits and ensure a relationship advantageous for everyone. We demonstrate that if the producer shares a part of the transportation or inventory savings with its partner, the CPFR method can be profitable for both partners and generate the greatest total system profit.

    Collaborative logistics is becoming more important in today’s industry. This is driven by increased environmental concerns, improved efficiency through collaborative planning supporting resources sharing and new business models implementation. This paper explores collaborative logistics and reports on business applications within the forest products industry in Sweden and Canada. It first describes current opportunities in collaborative planning. It then discusses issues related to building the coalition as well as sharing resources and benefits. Three business cases are described and used to support the discussion around these main issues. Finally, different challenges are detailed, opening new paths for researchers in the field.

    Collaboration for a two-echelon supply chain in the pulp and paper industry : the use of incentives to increase profit
    (2010-01-06) Lehoux, Nadia; D'Amours, Sophie; Frein, Yannick; Langevin, André; Penz, Bernard
    In our research, we study the case of a pulp and paper producer who decides to establish a partnership with one buyer. Using two different types of relationship, namely a traditional system without any collaboration scheme and Collaborative Planning, Forecasting and Replenishment, we develop decision models describing the producer and the buyer planning processes. We also identify which approach is more profitable for each actor as well as for the network, based on real costs and parameters obtained from the industrial case. We then test how different incentives can improve the traditional system and provide higher gains for each partner. Our results show that using incentives increases the system's profit by up to 4% if parameters are well defined.

    Value creation network of canadian wood fibre
    (Centre interuniversitaire de recherche sur les réseaux d'entreprise, la logistique et le transport, 2012-07-01) Marier, Philippe; Lehoux, Nadia; Beaulieu, Jean; D'Amours, Sophie; Ouellet, Denis
    In this paper, we describe the Canadian wood fibre value network by explaining what constitutes a value creation network, how to model this kind of network, and how it can be managed efficiently. Research for the forest industry conducted by national and international researchers as well as by Forac students are also provided. The paper finally reviews different technologies that could be useful to forest products companies in order to facilitate their decision-making process.
