Machine 1 O 2 3 Your answer: Setup cost($) Min. Z = 2x + 10x2 + 5x3 300 100 200 Min. Z = 300y + 100y2 + 2003 Production cost/unit($) Min. Z = 300x + 100x2 + 200x3 + 2x1 + 10x2 + 5x3 Min. Z = 2x1 + 10x2 + 5x3 + 300y1 + 100y2 + 200y3 + 2 10 If we want to formulate the problem as an ILP/BIP, which of the following would be the appropriate objective function? 5 Capacity (units) 650 850 1250
