A processor makes two components A & B which are then packages together as a final product. Each product sold contains one A and one B$.$ The processor can only do one component at a time. Either it can make A$\text{'}$s or B$\text{'}$s and there is a set$-$up time when switching from A to B$.$ Current plans are to make $100$ units of component A and then $100$ units of component B and then $100$ components of A then $100$ of B then so on$.$ The set$-$up and run times of each component are give below:
