    Tactical and operational harvest planning
    (Springer, 2014) Marques, Alexandra S.; Rönnqvist, Mikael; Audy, Jean-François.; D'Amours, Sophie
    The chapter focuses on the forest management decisions undertaken by the private industrial forestland owners concerning medium- and short-term forest planning. Firstly, the scope of forest tactical and operational planning is bounded by comparison with strategic planning as presented in this chapter and with the flow and transportation problems as they are presented in Chap. 9. Then, the chapter describes singular tactical and operational harvest planning decision problems, with emphasis on its specific business decisions as well as the modelling and solution approaches often found in the literature. The problems covered include: scheduling of harvesting operations, machine system/team assignment, harvest sequencing, harvest service adjudication, extraction of the logs, bucking & sorting strategies. The chapter further addresses integrated planning problems, distinguishing between problems with anticipation decisions, used to accommodate the impact on/from other planning problems, and fully integrated problems with more than one type of business decisions.

    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.

    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.

    Business models for collaborative planning in transportation : an application to wood products
    (Springer, 2007-01-01) Rönnqvist, Mikael; Audy, Jean-François.; D'Amours, Sophie
    Transportation is an important part of the wood fibre flow chain in forestry. There are often several forest companies operating in the same region and coordination between two or more companies is however rare. Latelv, the interest in collaborative transportation planning to support co-ordination has risen since important potential savings have been identified. Even though substantial savings can be realized, it seems that companies' willingness to collaborate is tightly linked to a business model driven by one or many leaders. In this paper, we study a specific business model where one company leads the development of the coalition. The impact of different behaviours of the leading company (i.e. altruistic, opportunistic) is illustrated using an industrial case study of eight forest companies.
