vorites Tools Help Page Safety Tools Problem 12-2 The following table lists the components needed to assemble an end item, lead times, and quantities on hand. End B 5 2 Amount on hand 0 127 27 1330 4 0 a. If 20 units of the end item are to be assembled, how many additional units of E are needed? (Hint You don't need to develop an MRP plan to determine this.) Additional units 135 b. An order for the end item is scheduled to be shipped at the stat of week 16. What is the latest week that the order can be starte and still be ready to ship on time? (Hint You don't need to develop an MRP plan for this part either.)Explanation / Answer
To determine the latest week when the order can be started , we need to examine items in level 0 level and corresponding time when they can be made ready. The items in lowest level are : E, F, G and H
Total profit from 4 regions under DECLINING scenario = 16000 + 11000 + 8000 + 2000 = 37000
Total profit from 4regions under STABLE scenario = 8000 + 11000 + 11000 + 8000 = 38000
a)If end item has to be released during start of week 16 , Item E should be made ready during
= Beginning of week 16 – Lead time of B – Lead time of E
= Beginning of week ( 16 – 1 – 2 )
= Beginning of week 13
b) end item has to be released during start of week 16 , Item F should be made ready during
= Beginning of week 16 – Lead time of B – Lead time of F
= Beginning of week ( 16 – 1 – 3 )
= Beginning of week 12
c)If end item has to be released during start of week 16 , Item G should be made ready during
= Beginning of week 16 – Lead time of C – Lead time of G
= Beginning of week ( 16 – 4 – 2 )
= Beginning of week ( 16 – 4 – 2 )
= Beginning of week 10
d)If end item has to be released during start of week 16 , Item E should be made ready during
= Beginning of week 16 – Lead time of C – Lead time of E
= Beginning of week ( 16 – 4 – 2 )
= Beginning of week 10
e)If end item has to be released during start of week 16 , Item H should be made ready during
= Beginning of week 16 – Lead time of D – Lead time of H
= Beginning of week ( 16 – 4 – 3)
= Beginning of week 9
= Beginning of week 16 – Lead time of D – Lead time of E
= Beginning of week ( 16 – 4 – 2)
= Beginning of week 10
Out of above, it is item H which should be made ready earliest i.e. during beginning of week 9
Thus the latest week the order can be started and yet would be ready to ship on time is week 9
LATEST WEEK WHEN THE ORDER CAN BE STARTED AND YET WOULD BE READY TO SHIP ON TIME IS WEEK 9
LATEST WEEK WHEN THE ORDER CAN BE STARTED AND YET WOULD BE READY TO SHIP ON TIME IS WEEK 9
