a) Draw the bill of materials b) Produce the MRP for the upcoming eight weeks c) Produce a list of all planned order releases

What is the MRP term for the time periods used in planning?

Given the product structure, master productionschedule, and inventory status in Figure 14.13, and assuming therequirements for each BOM item is I:a) develop a gross requirements plan for Item C;b) develop a net requirements plan for Item C.

Given the following MRP matrix for Item D:     The planned order release for period 3 is

m1

b) Prepare a master schedule based on the following information: Week: 1 2 3 5 Forecast 120 100 150 Orders 70 90 60 Initial inventory=100 Batch size = 200 4 80 30 80 20 6 100 10 7 120 0 8 110 0

8. Ajax produces two basic products called A and B. Each week, Paul, the owner, plans to assemble 20 product As and 8 product Bs. a. Given this information and the following product structure diagrams for A and B, fill out the MRP records (inventory status files) for component parts G and Y for the next seven weeks. X A Part G Gross requirements Y Scheduled receipts Projected available balance Planned order release Q = lot for lot; LT = 1; SS=0. 0 Y (2 required) G 10 B Z F Week 1 2 3 4 5 6 7 Part Y Gross requirements Scheduled receipts Projected available balance 67 Planned order release 1 10 Week 23 4 5 6 7 Q=lot-for-lot; LT=2; SS=0. b. Suppose 10 units of safety stock are required for part Y. What changes would result in the records? Would the MRP system produce any exception messages?

18. 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 start of week 8. There are currently 15 units of B on hand and 130 of E on hand, and 50 units of H are in production and will be completed by the start of week 2. Lot-for-lot ordering will be used for all items. A B(2) D(2) E(2) D(2) E(4) H(3) K H(3) K

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.
