Solution Decision Variables: Essentially we are interested in the amount produced on each machine. Hence let: Xi = amount of product i(i=1,2,3,4) produced on machine X per week y = amount of product i (i=2,3,4) produced on machine Y per week where x, >=0 i=1,2,3,4 and y, >=0 i-2,3,4 Note here that as product I must be processed on both machines X and Y we do not define yi. We can alternatively define yi as follows: yi amount of product i (i=1,2,3,4) produced on machine Y per week. But then we need to add the constraint i=yi Constraints: . floor space 0.1x1 + 0.15(x2 + y2) + 0.5(x3 + y) +0.05(x4 + + y)
