Claim One:
1. A computer-implemented method for managing fermentation feed in a biofuel production process, comprising: providing a dynamic multivariate predictive model of biomass concentration and water inventory for a fermentation feed of the biofuel production process; receiving a specified objective for the fermentation feed specifying a target biomass concentration for the fermentation feed; receiving process information, comprising water inventory information and biomass concentration information, from the biofuel production process; executing the dynamic multivariate predictive model in accordance with the objective using the received water inventory and biomass concentration information as input, thereby generating model output comprising target values for a plurality of manipulated variables of the biofuel production process, including target water and/or biomass flow rates contributing to the fermentation feed in accordance with the objective; and controlling the biofuel production process, including water and/or biomass flow rates related to the fermentation feed of the biofuel production process, in accordance with the plurality of manipulated variables to stabilize water/biomass balance in the fermentation feed in accordance with the specified objective, including the specified target biomass concentration.
