3. Identifying Our Network EthX transports ethanol throughout the eastern half of the U.S. 21 total nodes, 7 demand and 2 supply 33 arcs both directed and undirected Demand on the network is 904 cars per day Objective – Maximize the flow while minimizing cost

4. Model Assumptions Each arc has associated cost * C ij = Cost per day for movement of 1 car along arc Supply nodes located in areas that have the most production facilities Demand nodes are located at end points of major EthX. * Each arc has a capacity constraint U ij Capacity on each arc is ≤ capacity of node(i) Capacities on the intermediary nodes modified to accommodate total demand on network. * Information provided by CSX website * Information provided by CSX website

8. New York Daily News 12/07/2010 26 cars out of a 131 car train derailed near Chicago. 9 of these cars were loaded with Ethanol.

9. Potential Operator Problem A threat causes a delay of 12 hours but does not render this arc inoperable. Penalty added to the overall cost to traverse the affected arc. (∑cij/m)*1.5 = 4232 A terrorist attack is an actual attack which renders the affected arc inoperable.
