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?
