One unit of A is made of two units of B, three units of C, and two units of D. B is composed of one unit of E and two units of F. C is made of two units of F and one unit of D. E is made of two units of D. Items A, C. D, and F have one-week lead times; B and E have lead times of two weeks. Lot-for-lot (L4L) lot sizing is used for Items A, B, C, and D; lots of size 60 and 200 are used for items E and F, respectively. Item C has an on-hand (beginning) inventory of 10; D has an on-hand inventory of 50 ; all other items have zero beginning inventory. We are scheduled to receive 20 units of Item E in Week 2; there are no other scheduled receipts. If 20 units of A are required in Week 8 , use the low-level-coded bill-of-materials to find the necessary planned order releases for all components.
