(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Minimize Z = 3.5x + 6.5y

subject to

1. (1/3)x + y ≥ 1

2. 3.8x + 2.4y ≥ 5

and x ≥ 0, y ≥ 0

Use Big M method and then Two-Phase method interactively with IOR.jar and compare answers.

2. Relevant equations

3. The attempt at a solution

I am getting really confused with IOR, but this is what I have

Big M Method:

Minimize Z = 3.5x + 6.5y + Ma + Mb-->Max(-Z) = -3.5x - 6.5y - Ma - Mb-->

-Z + 3.5x + 6.5y + Ma + Mb = 0

subject to

1. (1/3)x + y - u + a = 1

2. 3.8x + 2.4y - v + b = 5

and x, y, u, v, a, b ≥ 0

I attached my IOR txt file... just wondering if it's all right?

Not sure how to do the Two-Phase method on iOR, there isn't an example in the book.. help please?
