abstract
2015 Elsevier B.V. This chapter presents an analysis of three main concepts involved in planning the supply chains for future biorefineries. First, the supply chain must include distributed systems that account for the economies of scale while simultaneously addressing the site selection for the installation of preprocessing hubs and central processing facilities. Second, the seasonal variation in the availability of the biomass resources must be considered in these supply chains. Finally, the optimal planning must take into account the multiobjective nature of the problem involving the optimization of the three aspects of a sustainable design: economic, environmental, and social issues. This chapter presents three mathematical programming models considering different key issues for the optimal planning of a biorefinery system and proposes procedures to solve these multiobjective problems. The proposed models were applied to several case studies for the optimal planning in Mexico where the importance of the key issues is highlighted.
