a. 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. Assume lot-for-lot ordering except for D, where multiples of 40 must be used.
A partially completed inventory record for the motor sub-assembly is shown in Figure 11.39. a. Complete the last three rows of the record by using the L4L rule. b. Complete the last three rows of the record by using the POQ rule with P = 2. c. Complete the last three rows of the record by using the POQ rule with P = 2. d. If it costs the company $1 to hold a unit in inventory from one week to the next, and the cost to release an order is $50, which of the lot sizing rules used above will provide the lowest inventory holding + order release cost?
Develop a material requirements plan for component H. Lead times for the end item and each component except B are one week. The lead time for B is three weeks. Sixty units of A are needed at the startof week 8. There are currently 15 units of B on hand and 130 of E on hand, and 50 units of H are inproduction and will be completed by the start of week 2. Lot-for-lot ordering will be used for all items.
