This is an exam question I was practising. I have the general understanding of Linear programming, but how would you go about finding the Decision Variables, Objective function and Constraints for this?
My Opinions: Decision variables: $M_1$- # of Model $1$ to be produced $M_2$ and $M_3$(similar definition as $M_1$)
Objective function: I'd Multiple the Cost to make in house by cost to buy from subtractor
to get Minimise: $3900M_1+7500M_2+27300M_3$
No idea where number order would go? Do I use it in the Constraints and multiply by the Hours?
Now, am I on the right track?
