Fact Sheet

Determining System Capacity to Accommodate Grain Flows by Rail to the Mississippi River at St. Louis



Start Date:  Sep 2005

End Date:
 Jun 2006






Problem Addressed:  

A global grain forecasting model has been built which forecasts production and consumption of grains by region and satisfies the 'excess' demand in one region by moving 'excess' supply from another region by the least cost route. Calibrating this model to historical data revealed a need to place constraints on certain low cost corridors. Of particular interest was the capacity of the system to accommodate grain flows by rail to the Mississippi river at St. Louis. Synthetic constraints were used to force the model to yield historical results. However, in order to forecast future flows, some understanding of the systems capacity and likely future capacity is needed.





Project objectives were to identify the current capacity of the land transportation system to deliver grains to the Mississippi river just below St. Louis (below L&D 27), identify the key components that govern this capacity, and examine the likely future of those components to forecast the future capacity of this part of the system.




This project improves understanding of system capacity and likely future capacity, which facilitates the forecasting of future flows at short-term (10-20 years) and long-term intervals (to the year 2060). This information is vital in defining a framework and the parameters for developing a forecasting model for port handling capacity .
