Goal Programming Solution Feedback Indicates That the D₄⁺ Level of 50

question 11

Multiple Choice

Goal programming solution feedback indicates that the d₄⁺ level of 50 should not be exceeded in future solution iterations. How should you modify your goal constraint ​
40 X₁ + 20 X₂ + d₄− + d₄⁺ = 300
​
To accommodate this requirement?

• A) Increase the RHS value from 300 to 350.
• B) Replace the constraint with 40 X₁ + 20 X₂ ≤ 350.
• C) Do not modify the constraint, add a constraint d₄⁺ ≤ 50.
• D) Do not modify the constraint, add a constraint d₄⁺ = 50.
