The U.S. Department of Energy, Oak Ridge National Laboratory, Idaho National Laboratory, National Renewable Energy Laboratory, and other research organizations collaborated on the Integrated Biomass Supply Analysis & Logistics (IBSAL) model developed in ExtendSim. This biomass supply chain model takes into consideration the logistical features of a supply such as the number of farms involved, average yield, the start and progress of harvest schedule, the moisture content of the crop, daily weather data, equipment specifications, and so on. Using this information, the model calculates drying and wetting of the biomass and workability of the soil. It is also being used to calculate costs per ton of biomass, energy input, and emissions (CO2) from equipment.
