The Transportation Model Method: Uses & Examples

Linear Programming (Definition, Methods & Examples)

For each of the following linear programming models, give your recommendation on which is the more efficient way (probably) to obtain an optimal solution: by applying the simplex method directly to this primal problem or by applying the simplex method directly to the dual problem instead. Explain. (a) Maximize Z=10 x1-4 x2 7 x3, subject to 3 x1-x2 2 x3≤ 25 x1-2 x2 3 x3≤ 25 5 x1 x2 2 x3≤ 40 x1 x2 x3≤ 90 2 x1-x2 x3≤ 20 and x1 ≥0, x2 ≥0, x3 ≥0 (b) Maximize Z=2 x1 5 x
