Consider the following problem.
Minimize Z = 2x1 + x2 +3x3,
Subject to

and
x1 ‰¥ 0, x2 ‰¥ 0, x3 ‰¥ 0.
(a) Using the two-phase method, work through phase 1 step by step.
(b) Use a software package based on the simplex method to formulate and solve the phase 1 problem.
(c) Work through phase 2 step by step to solve the original problem.
(d) Use a software package based on the simplex method to solve the original problem.
