MBI Linear Programming Example (pp. 46-47)

The Decision Variables are X₁ = the number of units of CC-7 to produce, X₂ = the number of units of CC-8 to produce.

The model is to

Maximize total profit Z = 8000 X₁ + 12000 X₂

subject to

Labor) 300 X₁ + 500 X₂ <= 200000

Budget) 10000 X₁ + 15000 X₂ <= 8000000

MktCC7) X₁ >= 100

MktCC8) X₂ >= 200

Additional Exercise

What is the origin of the term rule of thumb which is commonly used to describe heuristic methods? Can you think of a better term to use?
