The following table provides the time in minutes required by each part: Product Production time in min Lathe Drill press 5 3 6 2 2 3 4 5 4 7 4 Additionally, the number of units of part 1 may not exceed that of part 2 Assuming that X; : number of units need to be produced from product i, wherei e {1,2,3,4} The constraints and the objectives that are used to balance the two machines by limiting the difference between their total operation times to at most 30 minutes", are: Select one: Minimize si + + + S + 5x + 6x2 + 4x3 + 7x4 + si - st = 30 3x} + 2x2 + 5x3+4x4 + 53 - st = 30 Minimize -3 ; ++ 2xy + 4x2 - X3 + 3x4 + 53 - 5 = 30 - 2x1 - 4x2 + x3 3x4 +s4 - s1 = 30 Minimize 5 2 st 5x1 + 6x2 + 4x3 + 7x4 + si-st = 30 3x + 2x2 + 5x3 + 4x4 + s3 - st = 30 Minimize sz + st 3x1 + 2x2 + 5x3 + 4x4 + 53 - s = 30 Minimize si +st 5x + 6x2 + 4x3 + 7x4 + si-st = 30
