    Sustainability in the forest supply chain considering the efficient use of residues and byproducts
    (2015) Corsano, Gabriela; Campanella, Sandra; Montagna, Jorge Marcelo
    Supply chain (SC) globally integrates production units with raw material sources and customers, and coordinates all input and output flows (materials, information, finance, etc.) so that the products are produced and distributed in the right amounts, in appropriate locations and at the right time. These activities involve complex tasks that have different tradeoffs between the involved actors and require significant effort to coordinate the common actions. In particular, the forest SC has many heterogeneous participants, therefore, its integration is a challenging issue. One of the main aspects in the forest industry is the huge amount of generated residues and by-products generating through the wood mechanical transformation, from the harvest to the final product production. The residues use has not receive much attention, and its appropriate and efficient use is affected by many factors, as big involved volume, which increases the transportation cost. Nowadays, residues are burned in order to avoid its accumulation. This generates smoke, ash and gases impacting the environment, increasing the greenhouse effect and modifying the landscape. With the aim of avoiding these drawbacks, in this work a mixed integer linear programming (MILP) model for the optimal design and planning of the forest SC is proposed. The formulation considers different production alternatives, with the objective of maximizing the net benefit, generating the sustainable design of the overall network. This work is developed considering the particular characteristics of the Argentinean forest industry, but it can be easily adapted for other geographical regions. The proposed approach represents a useful tool for decision making and analysis of different production-distribution scenarios of sustainable SCs.

    Supply chain planning considering the production of defective products
    (2014) Corsano, Gabriela; Montagna, Jorge Marcelo; Ferrara, Miguel Angel
    When the markets become more competitive, the customer satisfac-tion level starts to be a more important factor. One of the principal components to achieve the customer satisfaction is to minimize the amount of defective or non-standard products. Therefore, it is convenient to consider decisions about product quality when the supply chain is planned. In this work, a mixed integer linear programming mathematical (MILP) model is developed for the supply chain planning, which determines impact of different decisions over the ex-pected number of defective products. These decisions are: supplier selection, inbound control methods selection, and production process selection. The ob-jective function is the cost minimization associated to the supply chain plan-ning.
