In the Green Grass shipping model, we currently assume that if a customer’s order is satisfied, it must be satisfied from a single plant. Suppose instead that it

can be satisfied from more than one plant. For example, if the company decides to satisfy Dallas’s order, it could ship part of this order from Denver and part from Phoenix (or some other combination of open plants). Continue to assume, however, that the company must satisfy either all or none of each customer’s order. Modify the model appropriately and use Solver to solve it. Does the solution change?
