Seagate Technology is producing Barracuda hard drives for personal computers. Each hard drive consists of one Head-Disc Assembly (HDA) and one application specific integrated circuit (ASIC). An HDA consists of a Head and 2 counts of Media disc. Gross requirements for the Barracuda hard drives for the next 7 weeks is given below: Seagate also carries ASIC as service parts for its repair customers. Forecasted service parts requirements for ASIC are given below: Following information is available regarding the initial inventory levels, lead times, safety stocks and lot sizing policies of the five items: The setup cost for Media is $100. The setup cost for ASIC is $200. Inventory holding cost per unit per week is $0.5 for Media, and $1.0 for ASIC. Inventory holding cost is charged at the end of each week for ending inventory. For Hard drive, there is a scheduled receipt of 80 units to be delivered at the beginning of week 1,40 units of scheduled receipt to be delivered at the beginning of week 2 . For Head, there is a scheduled receipt of 50 units to be delivered at the beginning of week 1 . For Media, there is a scheduled receipt of 60 units to be delivered at the beginning of week 1. For ASIC, there is a scheduled receipt of 80 units to be delivered at the beginning of week 1 . A. Develop a 7-week material plan for all 5 items. Show all your work. B. Consider the item Head. Suppose the following events happened during the first week - An inventory cycle count on Monday revealed that the only 100 units were available for use (rather than the original 140). - The scheduled receipts of 50 are received on Tuesday. Quality control on Wednesday revealed that only 20 are functioning properly. I. Using a bottom-up replanning approach, find out what problem these events will cause (Assume everything goes as planned for other items). Recommend two alternatives to solve the problem. Suppose you do not take any action to solve the problem during the first week. What is the resulting MRP record for the Head at the beginning of week 2? (Update only the record for the Head) Use the following format for MRP tables
