(A little sensitivity analysis.) You are given the final chart, with the optimal solution, for a transportation problem; note that the cell in the (4, 2) position is blank, i.e., the variable 242, with an objective coefficient (unit cost) of C42 = 18, is nonbasic. What range of values of C42 will keep the solution in the chart optimal? Hints: In this method, how do we tell that our latest solution is optimal?
