Why are non-negativity constraints (x ≥ 0, y ≥ 0) standard requirements in production-based linear programming models?
Test yourself: pick an answer
Reveal answer & explanation
Correct answer: C) Because physical quantities of products manufactured or resources consumed cannot be negative.
Explanation
In real-world business scenarios, it is physically impossible to produce a negative number of tables or work negative hours. Non-negativity constraints restrict the graph to the first quadrant to reflect this reality.
