1) The model for the transportation problem consists of 18 decision variables‚ representing the number of barrels of wastes transported from each of the 6 plants to each of the 3 waste disposal sites: = Number of Barrels transported per week from plant ‘i’ to the j-th waste disposal site‚ where i = 1‚ 2‚ 3‚ 4‚ 5‚ 6 and j = A‚ B‚ C. The objective function of the manager is to minimize the total transportation cost for all shipments. Thus the objective function is the sum of the individual
