The solution formulation to this problem has to be typed using xi's (or xii's) as your decision variables. You are not to shorten either the objective function or any of the constraints using '...'s. A corporation owns 3 plants, 2 warehouses and 3 factory retail outlets for its one product that it manufactures and sells. The following diagram indicates the paths that this product can follow from plants to warehouses and from warehouses to retail outlets; the monthly capacities at each of the plants; the monthly demands at each of the retail outlets; and, the $ costs of shipping each unit along each of the paths. Your objective is to formulate a model that will allow this corporation to minimize its total cost. You are not to solve this problem, just formulate it!
