Planning with limiting factors

3.3 Step 3: formulate the constraints

Example 2, continued

Subject to:

 In Department A, 8x + 10y ≤ 11,000 hours

 In Department B, 4x + 10y ≤ 9,000 hours

 In Department C, 12x + 6y ≤ 12,000 hours

 Non-negativity constraint: 0 ≤ x, y.by the inequality y ≤ 600.

Sales demand for Product Y is also a constraint, that can be expressed by the
inequality y ≤ 600.
