Sorting and Blending Under Quality Uncertainty: Application to Wheat Protein

Author

  • Johnson, D. Demcey

Abstract

Quality uncertainty is of considerable interest to the grain industry. In this paper, uncertainty is incorporated in a model of grain blending decisions. A mixed-integer, nonlinear optimization problem is developed. Simulations illustrate the effect of crop quality on blending decisions, and the effect of blending activities on the distribution of protein within a wheat marketing channel.
