In the United Copiers service center model, we assumed that a customer is serviced totally by a single service center. Suppose a customer can be serviced partly by multiple service centers. For example, the customer in Denver could get half of its service from Dallas and the other half from San Francisco. In this case, we assume that half of Denver’s annual trips would be made from Dallas reps and half by San Francisco reps. Modify the model appropriately and then solve it with Solver. How do you interpret the optimal solution? (Hint:Allow the changing cells in the Assignments range to be fractional values between 0 and 1.)
