Question
Problem 12-3 The following table lists the components needed to assemble an end item, lead times (in weeks), and quantities on hand Amount Item Lead Time on Hand Direct Components End 8 13 18 26 B (2), J(3) G (2), B(2) H(4), B(2) 4 a. If 43 units of the end item are to be assembled, how many additional units of B are needed? (Hint You don't need to develop an MRP plan.) Additional units b. An order for the end item is scheduled to be shipped at the start of week 10. What is the latest week that the order can be started and still be ready to ship on time? (Hint You don't need to develop an MRP plan.) The latest weekExplanation / Answer
A.
End items required = 43
End item requires:
86 units of L, 43 units of C and 129 units of K
Net requirement of L = 86-8 = 78
Net requirement of C = 43-13 = 30
Net requirement of K = 129 – 18 = 111
Gross requirement of B = 78*2 + 30*2 + 111*2 = 438 units
B quantity on hand = 26
Net requirement of B = 438-26
Net requirement of B = 412 units
B.
End-L-C-K = 2+2+3+3 = 10 week
End-B-J = 2+2+3 = 7 week
End-G-B = 2+3+2 = 7 week
End-H-B = 2+3+2 = 7 week
So, latest week to start = 10-10 = week 0
