2.2. Formulation of the proposed model
This section presents a multiperiod, multiobjective MILP model to design anaerobic digestion based biomass to energy supply chains. The aim is to make decisions corresponding to: (1) procurement and allocation of the resources; (2) configuration of the supply chain network with related connections and capacities; and (3) inventory, production and logistics management. Notations and related descriptions for model indices, input parameters and decision variables are presented as
