Environmental, Societal and Economical optimization of a bioethanol supply chain

Abstract

Abstract The objective of this contribution is to present a mathematical model (Mixed Integer Linear Programming) for the facilities and biorefinery locations, and the logistic management. For the model formulation, we first need a geographical discretization of the region in which the supply chain would be implemented and the identification of the different biomass sources and their availability in this region. The technological, ecological, economic and social data are also mandatory to run the model. As in supply chain there are short-term and mid-term decisions, the time horizon must be discretised. The original contents of the model are threefold: integration of multiscale aspects, taking into account of the biomass characteristics, optimization of the supply chain with economic, environmental and social criteria. As a result the model determines the number, the location and the capacity of bio refinery and facilities.
