_________________________________________________________________________________ BUSI 410 - Homework #2 Solutions 1. Let x i denote the tons of ore produced at mine i , i = 1, 2, 3, 4. Then, a suitable (linear) decision model can be the following. 1234 12 34 1 2 min 37 46 50 42 0.7 +0.6 0.5 0.3 940 350 530 xxxx xx x x + ++ ++≥ 3 4 610 490 , , , 0 x x b i. From the solver’s optimal solution in spreadsheet “mines” we read that mine 4 has slack capacity of 250 tons. ii. From the spreadsheet “mines sensitivity report” we read that the capacity constraint of mine 1 has the most negative shadow price. Therefore, capacity of mine 1 would reduce the company’s cost the most if it were to be increased. 2. Let x and y denote the number of copies of the restaurant and entertainment and of the real estate guide respectively. Then, a suitable linear decision model can be the following. max 0.5 0.75 0.17 0.25 4,000 18,000 8,000 8,000 xy x y + +≤ , 0 b i. From the solver’s optimal solution in spreadsheet “publisher” we read that \$140 is not spent.
