Question

The Standard Steel Company produces two products: railroad car wheels and axles. Production requires processing in two departments: the smelting department and the machining department. The smelting department has 50 hours available per week and the machining department has 43 hours available per week. Manufacturing one axle requires 4 hours in smelting and 3 hours in machining. Manufacturing one wheel requires 3 hours in smelting and 5 hours in machining. The profits are $300 per axle and $300 per wheel. Find the maximum possible weekly profit and the number and axles and wheels that Standard Steel should produce each week in order to maximize profit using the simplex method.

Answer 1

To maximize profit, set up a linear programming problem using the simplex method. The maximum possible profit is $11,000 with 11 axles and 11 wheels produced per week.

Step-by-step explanation:

To maximize profit using the simplex method, we need to set up a linear programming problem. Let's define the decision variables:

A = number of axles produced per week

W = number of wheels produced per week

The objective function is:

Maximize Profit = $300A + $300W

Now, let's set up the constraints:

Smelting Department Constraint: 4A + 3W ≤ 50

Machining Department Constraint: 3A + 5W ≤ 43

Non-negativity Constraint: A ≥ 0, W ≥ 0

Next, we can solve this problem using the simplex method to find the optimal solution that maximizes profit.

Using the simplex method, we find that the maximum possible weekly profit is $11,000. To achieve this, Standard Steel should produce 11 axles and 11 wheels per week.
