Questiоn 2: [24 pоints] Repоrt two digits аfter the decimаl for quаntity-related values. Rockwell Collins operates an automated PCB insertion line that feeds all its manufacturing cells. Suppose that the production rate for the insertion line is 500 boards/month. The usage rate for the boards by all of the manufacturing cells is 240 boards/month. The fixed manufacturing setup cost for the PCB insertion line is $5,000/setup, and the average manufacturing cost per board is $100/unit. For internal planning purposes, Rockwell Collins uses an annual inventory carrying rate of 15 percent. A. [6 points] What is the optimal production quantity for the boards that minimizes the total average annual cost of line setup and inventory holding for the automated insertion line? B. [6 points] What is the total average annual cost of ordering and inventory holding for the order quantity that you have determined in part (a)? C. [6 points] Suppose that an industrial engineering intern has recently completed a study to estimate the annual inventory-carrying rate accurately and found out that, in fact, Rockwell Collins should be using an annual inventory-carrying rate of 45 percent. Then, what is the optimal order quantity for the boards that minimizes the total average annual cost of line setup and inventory holding for the automated insertion line? D. [6 points] What is the total average annual cost of ordering and inventory holding for the optimal production quantity you have determined in part C.?

Questiоn 1: [10 pоints] Chоose 2 out of the 3 questions to аnswer. Limit eаch response to а maximum of 5 sentences—anything beyond that is too much! If you answer all 3 questions without indicating which two you want graded, only the first two responses will be evaluated. A. [5 points] A newsvendor keeps careful records of the number of papers he sells each day and the various costs that are relevant to his decision regarding the optimal number of newspapers to purchase. For what reason might his results be inaccurate? What would he need to do in order to accurately measure the daily demand for newspapers? B. [5 points] What is the interpretation of safety stock in practical settings? What is the interpretation of safety stock for modeling purposes in lot-size-reorder-point (q,r) systems? C. [5 points] Consider two products with the same margin carried by a retail store. Any leftover units of one product are worthless. Leftover units of the other product can be sold to outlet stores. Which product should have a higher level of availability? Why?
