It is assembled from2 components worth $50 total. The value added in produc-tion (for labor and variable overhead) is $60 per unit, bring-ing total costs per completed unit to $110. The average leadtime for the part is 6 weeks and annual demand is 3,800 units,based on 50 business weeks per year.a. How many units of the part are held, on average, in cycleinventory? What is the dollar value of this inventory?b. How many units of the part are held, on average, in pipe-line inventory? What is the dollar value of this inventory?(Hint: Assume that the typical part in pipeline inventoryis 50 percent completed. Thus, half the labor and variableoverhead cost has been added, bringing the unit cost to$80, or $50 + $60>2).arrow_forwardsniparrow_forward

- You have developed the following simple product structure of items needed for your gift bag for a rush party for prospective pledges in your organization. You forecast 200 attendees. Assume that there is no inventory on ha nd of any of the items. Explode the bill of material. (Subscripts indicate the number of units required.)arrow_forwardI understand that as per the calculations, the gross requirement for week 3 is 50 (25*2) (Item A's order releases), week 5 is 190 (20*2) + (150*1) (Item A's order releases + Item B's order releases), and week 6 is 300 (150*2) (Item A's order releases). But I want to know why do we do it that way because If I have a similar question do I always multiply item A's order release for week 3 by 2, week 5 (Item A's order releases x 2 + Item B's order releases x 1), and and week 6 (Item A's order releases x 2 ) I want to understand why we do that so I can anwser a similar question I don't understand why we do that have way just that you did it that wayarrow_forwardConsider the bill of material for product P and the data given in the following table.
