Post Optimality and Sensitivity Analysis (PO/SA) A. Changes that affect FEASIBILITY: 1. Changing the right-hand-side (RHS) 2. Adding a new constraint Example A: Consider the following LP: Maximize z = 3x1 + 2x2 Subject to X1 + X2 3 4 2x, + X2 S 10 Xy,X, 20 Optimal tableau: RHS z 0 130 12 S201- 212 Find how does each of the following scenarios affect the current optimal (and feasible) solution: a. Change the value of b, to be 8. (Answer: the current solution becomes infeasible, newz 18) b. Add the constraint: X: + 3x2 S 15 (Answer: the current solution is optimal and feasible) c. Add the constraint: 4x, + 5x2 12 (Answer: the current solution becomes infeasible, new 2-9)
