One unit of Part C is used in item A and in item B. Currently, we have 10 As, 20 Bs, and 100 Cs in inventory. We want to ship 60 As and 70 Bs. How many additional Cs do we need to purchase?
Product A is made from components B, C, and E. Item C is a subassembly that requires 2 units of D and 1 unit of E. Item B also is an intermediate item, made from D. All other
usage quantities are 2.

- Can you assist me with Problem 7 errors. Thank you greatlyarrow_forwardOne unit of A is made of two units of B and one unit of C. B is made of three units of D and one unit of F. C is composed of three units of B, one unit of D, and four units of E. D is made of one unit of E. Item C has a lead time of one week; items A, B, E, and F have two-week lead times; and item D has a lead time of three weeks. Lot-for-lot (L4L) lot sizing is used for items C, E, and F; lots of size 20, 40, and 160 are used for items A, B, and D, respectively. Items A, B, D, and E have on-hand (beginning) inventories of 5, 10, 100, and 100, respectively; all other items have zero beginning inventories. We are scheduled to receive 10 units of A in week 3, 20 units of B in week 7, 40 units of F in week 5, and 60 units of E in week 2; there are no other scheduled receipts. If 20 units of A are required in week 10, use the low-level-coded bill-of-materials (product structure tree) to find thenecessary planned order releases for all components.arrow_forwardIf a work order instructs you to package 620 boxes of product and each product contains 2 bags of 50 sheets of film, how many sheets of film will need to be produced?arrow_forward
