8. Three components – x, y, and z- Setup time, run time, and lot size for each item are as follows: are made at the same machine via lot production. Setup time, hr. 2 Component Run time, min. Lot size 1 800 1.5 400 500 1 One lot of each component is waiting at the machine to be processed: each component is needed immediately. (a) What is the minimum lead time for obtaining all three components? (b) We want to reduce this lead time to 12 hours by reducing setup time and lot size by the same factor for all items. What should the resulting setup time and lot size be for each component?

One unit of A is made of two units of B, three units of C, and two units of D. B is composed of one unit of E and two units of F. Cis made of two units of Fand one unit of D. E is made of two units of D. Items A. C. D. snd F have one-week lesd times; B and E have lead times of two weeks. Lot-for-lot (L4L) lot sizing is used for Items A, B, C, and D: lots of size 50 and 220 are used for Items E and F. respectively. Item C has an on-hand (beginning) inventory of 20; D has an on-hand inventory of 50; all other items have zero beginning inventories. We are scheduled to receive 20 units of Item E in Week 2; there are no other scheduled receipts.
