Need a solution for this case study using principles of Supply Chain Management.

We will expand our potato shipping example to demonstrate the formulation of a transshipment model. Potatocs are harvested at farms.in Nebraska and Colorado before being shipped to the three disfribution centers in Kansas City, Omaha, and Des Moines, which are now trans. shipment points. The amount of potatoes harvested at each farm is 300 tons. The potatoes are then shipped to the plants in Chicago, St. Louis, and Cincinnati. The shipping costs from the distributors to the plants remain the same, and the shipping costs from the farms to the distributors are as follows. The basic siructure of this model is shown in the following graphical netwoik. As with the transportation problem, this model includes supply constraints at the farms in Nebraska and Colorado, and Jemand constraints at the plants in Chicago, St. Louis, and Cincinnati. However, there are several additional mathematical relationships that express the condition that whatever amount is shipped into a distribution center must also be shipped out: that is, the amount shipped into a transshipment point must equal the amount shipped out
