As the production planner for Xiangling Hu Products, Inc., you have been given a bill of material for a bracket that is made up of a base, 2 springs, and 4 clamps. The base is assembled from 1 clamp and 2housings. Each clamp has 1 handle and 1 casting. Each housing has 2 bearings and 1 shaft. There is no inventory on hand.
Your boss at Xiangling Hu Products, Inc., has just provided you with the schedule and lead times for the bracket. The unit is to be prepared in week 12.The lead times for the components are bracket (1 week), base (1 week), spring (1 week), clamp (1 week), housing
(3weeks), handle (2weeks), casting (4weeks), bearing (1 week), and shaft (1 week).

One hundred twenty units of end item Z are needed at the beginning of week 7. Prepare a material requirements plan for component C. Take into account that on hand there are 40 units of Z,70 units of A, 100 units of B, and 30 units of C. Also, there is a scheduled receipt of 20 units ofcomponent C in week 4. Lead times are two weeks for Z and B, and one week for the other components. Lot-for-lot ordering will be used for all items b. Ninety-five units of end item E are needed at the beginning of week 7. Prepare a material requirements plan for component D. Take into account that 5 units of E are currently on hand, as well as50 units of B, 100 units of C, and 80 units of D. Also, 30 units of C have been outsourced and areexpected to arrive in week 4. Lead times are two weeks for E and C, and one week for the othercomponents.
