A Classic Network Design Case-- and a nice $5MM Savings
This map shows a classic network design case. This client was producing most of its product in northwest Mexico with some product coming from the Virginia plant.
Like many firms, they were just distributing product from the plant where the product was made. The baseline map shows the current situation.
They wanted to do an analysis to determine a better distribution strategy. The result on the right shows the optimal distribution strategy. Thy shipped full trucks loads from the plant in Mexico to the warehouse in Virginia and then on to the customer.
This solution has much more expense in transportation from the plant to the warehouse. However, this is more than offset by the savings on shipments to customers. The optimal solution resulted in $5MM in savings (about a 25% reduction in transportation costs).
Although this case looks rather simple, it wasn't clear at the start whether the best solution would have one warehouse in the center of the country, two warehouses not located at the plants, or a third warehouse. And, it wasn't clear how the country should be split. And, finally, with a lot at stake in terms of savings, and moving capabilities, it is important to do a robust study to make sure you have covered all the angles.
