8) Ron thinks that selling a large quantity of SP1 may be more profitable for his firm and would like the number of SP1 produced to be at least 100 units more than the number of SP2 produced. Would you recommend this plan or not? Explain your reasoning. 9) Ron thinks that if the firm can acquire more parts, they could make more profit. Which part (5) would you suggest that the firm orders? Why? 10) Ron thinks that another possible strategy for the firm is to provide a diverse set of printed circuit boards, giving customers more choices. However, in the current solution, the firm only produces SP1 and SP2. How much should the profit of SP3 change to be considered in the optimal solution? 11) How much can PCB Manufacturing increase the per-unit profit of SP1 and SP2 and still keep the same optimal production plan? (You can approximate.) 12) Suppose the firm increases the per-unit profit of SP1 and SP3 by $1. How would the optimal solution and the optimal profit change? What if the per-unit profit of SP1 and SP3 increased by $2 per unit? 13) The production engineers have found a way of reducing the parts requirements for a unit of SP3. With this new production method, one unit of SP3 now requires 4, 2, and 1 units of parts 1,2, and 3, respectively. Should they consider implementing this new production method? If they implement this new production method, would the production plan change
