Using the information given below, prepare an MRP for Item F. 100 chain saws are needed at the start of week 7 and 125 chain saws are needed at the start of week 8. The inventory and the product structure tree are listed below in the problem solution: a. Product tree structure: Saw A (2) B C14) E3) F D(2) F(3) E(2) D(2) Item On-Hand Lot Size Rule Lead Time (weeks) Scheduled Receipts SAW 1 5 Lot for lot A 1 8 5 (WK 1) Q=30 B 1 5 Multiples of 5 1 1 1 1 15 5 (WK 2) Multiples of 12 D 2 10 10 (WK 2) Q=75 E 2 20 10 (WK1) Multiples of 7 F 10 15 (WK 2) Q=30 There are 3 lot-size rules you must be familiar with: 1) Lot-for-lot: Planned order receipts = Net Requirement 2) Q = ?: e.g. Q = 30 means that the minimum quantity ordered (planned order receipt) should be 30. For example, of net requirement is 25, then the planned order receipt should be 30 (as 25 is less than 30). However, of the net requirement is 40, then the planned order receipt should be 40 (as 40 is greater than 30 or the minimum quantity) 3) Multiples of ?". e.g. multiples of 5, if net requirement is 33. Since 33 is not a multiple of 5, the planned order receipt will be the next higher multiple of 5, which would be 35. If net requirement was 60, then the planned order receipt would be 60 since it is a multiple of 5
