3. Xor Computing makes cutting-edge gaming laptops at two manufacturing plants, referred to as 01 and 10. It then sends the laptops in bulk to three distribution hubs, labeled A, B, and C. These three hubs send laptops to retailers in California, Oregon, 2 New York, and Maryland. The below table provides the per-unit production costs and maximum production at each plant. This table provides the demand at each retailer: The following tables provide the per-unit shipping costs from plant to distribution hub, and from distribution hub to retailers. (a) Formulate this problem as a transshipment problem. Make sure to define your variables and provide brief descriptive labels for your constraints. (Hint: Define a set of nodes for the plants, a set of nodes for the distribution hubs, and a set of nodes for the retailers.) (b) Solve your model from part (a) using MATLAB or other software. 3.
