firm analysis of biofuel systems incorporating risk and uncertainty at the farm and conversion facility levels

The Firm Level Agricultural Risk and Environmental Modeling Framework (FLARE) consists of risk mathematical programming models firm level economic models and includes representative farm models and biorefinery conversion models, incorporates switchgrass feedstock harvest, storage and delivery models, and simulates output and net revenues for traditional beef cattle and crop enterprise choices considering typical resource constraints such as soil type, labor availability, field day availability, and crop rotation requirements, etc.  The biorefinery feedstock model simulates switchgrass yields and the costs of production including opportunity costs on land by soil type for a designated feedstock draw area.  The mixed integer programming model optimizes the production and delivery of switchgrass feedstock to the biorefinery considering costs of production, harvest and preprocessing method, storage method, and dry matter losses during handling and storage.
