Omega Manufacturing Company has excess manufacturing capacity and is considering
devoting its excess capacity to product 1,2, and 3.
The production process uses three types of machines and the available capacity on the machines is as follows:
Milling Machine: 550 hrs/week
Lathe 350 hrs/week
Grinder 150 hrs/week

Profits and machine requirements in hours for the three products are as follows:
Catagory Products 1 Product 2 Product 3
Profit 50 20 25
Milling Machine 9 3 5
Lathe 5 4 0
Grinder 3 0 2

Sales Potentials for Product 1 and 2 exceeds max production and Product 3 is expected to sell no more than 20 units per week. Formulate the LP PROBLEM

I really appreciate any help I can get on the problem. I have been struggling with it for sometime and I have a couple more like it so if I can see how to solve this one I can work through the rest. Thanks very much!

Formulating the problem means
  • Defining the problem variables.
  • Stating the objective function that is to be maximized or minimized.
  • Stating the constraints in the form of inequalities.

Start with the things I've listed. Doesn't your textbook show any examples of linear programming problems?

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
