8. Three plants are to be located at points X1=(x1.y), X2=(x2,72), and X3=(x3,73). There are five customers currently located at the points P1=(3,15), P2=(25,45), P3=(45,54), P4=(15,53), and P5=(45,15). The shipment of products from the plants to customers per month, measured in truckloads, are 90, 110, 150, 75, and 175 truckloads, respectively. The cost of transporting a truckload of product from the plants to customers is $1 per unit distance. Assume the capacity of each plant is 200 truckloads of product, a customer is served by only one plant, no interaction between any two plants and rectilinear distance measure between plants and customers. Formulate the problem as a mixed integer linear program and solve. 8. Three plants are to be located at points X1=(x1.y), X2=(x2,72), and X3=(x3,73).
