b. How many unique components does product A have at all levels?
c. Which of the components are purchased items?
d. How many intermediate items does product A have at all levels?
e. Given the lead times (LT) in weeks noted on Figure 16.27, how far in advance of shipment must a purchase commitment be for any of the purchased items identiﬁed in part (c)?
3) What is the lead time [in weeks) to respond to a customer order for product A, based on the BOM shown in Figure 16.28 (attached), assuming no existing inventories or scheduled receipts?
1.a. I has 4 immediate parents (2 are E, 1 is F and 1 is G). There are 3 unique components. E has 3 immediate parents (2 are C and 1 is B). There are 32 unique components.
