Lab Week 5 Problem Solutions CHAPTER 3 LP: SENSITIVITY ANALYSIS AND COMPUTER SOLUTION INTERPRETATION 5. Protein/Fibre LP Model a. Range of optimality: 5 0 1 x Range of optimality: < 2 4 . 6 x Adjustable Cells Final Reduced Objective Allowabl e Allowabl e Cell Name Value Cost Coefficient Increase Decrease \$C\$ 7 Production X1 8 0 4 1 4 \$D\$ 7 Production X2 0 2 8 1E+30 1.6 b. The decrease would have no effect on the optimal values, but it would change the objective function. The new z would be 24. c. The shadow price is 1\$. It is valid from 20 to infinity. d. The shadow price is 0\$. It is valid from negative infinity to 24. ; e. It would have no impact on cost, as the shadow price is zero.
