The recommended cost that minimizes the total spending of the company is $7 million
How to formulate a binary integer programming modelThe dataset can be represented using the following table:
Data center Cost (Million) Secure Servers Super Secure Servers
Michigan (x₁) 2.5 50 30
New York 1 (x₂) 3.5 80 40
New York 2 (x₃) 3.5 40 80
Ohio (x₄) 4.0 90 60
California (x₅) 2.0 20 30
Total 90 90
The above table can be represented using the following model
Minimize Z = 2.5x₁ + 3.5x₂ + 3.5x₃ + 4.0x₄ + 2.5x₅
Where the constraints are:
30x₁ + 40x₂ + 80x₃ + 60x₄ + 30x₅ ≥ 90
50x₁ + 80x₂ + 40x₃ + 90x₄ + 20x₅ ≥ 90
Where x₁, x₂, x₃, x₄, x₅ ≥ 0
The solution to the modelTo do this we make use of a statistical calculator.
From the calculator, we have:
x₁ = 0, x₂ = 1, x₃ = 1, x₄ = 0, x₅ = 0
Substitute these values in Z = 2.5x₁ + 3.5x₂ + 3.5x₃ + 4.0x₄ + 2.5x₅.
So, we have:
Z = 2.5 * 0 + 3.5 * 1 + 3.5 * 1 + 4.0 * 0 + 2.5 * 0
Evaluate
Z = 7
Hence, the recommended cost that minimizes the total spending of the company is $7 million
