Ten specifications of a linear programming model are developed to jointly select the least cost locations of grain production and interregional grain transportation in the United States. Analyses are based on 1980 demand projections for wheat, soybeans, and feed grains. Seven model options represent alternative transportation systems and include alternative cost estimates for railroad and barge transportation. Three other options are specified to analyze interdependencies between grain exports and transportation. Results suggest that choice of transportation mode and grain flows are sensitive to transportation cost changes and the distribution of exports among ports but the location of grain production is not.
