Hello, I need help with this entire problem! Thank you for your answers and solutions.

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 Fand 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 50 and 180 are used for Items E and F, respectively. Item C has an on-hand (beginning) inventory of 15; D has an on-hand inventory of 50; all other items have zero beginning inventories. We are scheduled to receive 20 units of Item Ein 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. Order A: units in Week Order B: units in Week Order C: units in Week Order D: units in Week 2; units in Week 5; and units in Week 6 Order E: units in Week Order F: units in Week
