  • Currently, 4,600 pounds of steel and 5,000 machine hours are available.
  • To meet customer demands, exactly 950 total products must be produced.
  • Customers also demand that at least 400 units of Product W be produced.

Formulate an LP that can be used to maximize sales revenue for the manufacturer.

LP Formula

Let Pi be the number of product type i produced by the manufacturer, where i = X, Y, X, and W.

MAXIMIZE  4 PX + 6 PY + 7 PZ + 8 PW

Subject To

2 PX + 3 PY + 4 PZ + 7 PW <= 4600   ! Available Steel

3 PX + 4 PY + 5 PZ + 6 PW <= 5000   ! Available Machine Hours

PX + PY + PZ + PW    = 950               ! Total Demand

                            PW >= 400               ! Product W Demand

PX >=0

PY >=0

PZ >=0

PW >=0

Suppose the sales price of Product Z is decreased by 60¢. What is the new optimal solution to the LP?

Objective Function Value:

A factory makes a product out of three infinitely- divisible ingredients X, Y , and Z. The ingredients cost p, q, and r pounds per kg, respectively, with p, q, r > 0 all different, and the factory has a budget of B > 0 pounds. The value of the product is some function g(x, y, z)=exp(x+y+z). of the weight of the ingredients. Solve this problem when the factory wishes to maximize the value of their product, within their budget.
