You have just received an order for 25 units of an industrial robot, which is to be delivered at the start of week 7 of your schedule. Using the following information, determine how many units of subassembly G to order and the timing of those orders, given that subassembly G must be ordered in multiples of 80 units and all other components are ordered lot-for-lot.

B is made of three units of D and one unit of F. C is composed of three units of B, one unit of D, and four units of E. D is made of one unit of E. Item C has a lead time of one week; items A, B, E, and F have two-week lead times; and item D has a lead time of three weeks. Lot-for-lot (L4L) lot sizing is used for items C, E, and F; lots of size 20, 40, and 160 are used for items A, B, and D, respectively. Items A, B, D, and E have on-hand (beginning) inventories of 5, 10, 100, and 100, respectively; all other items have zero beginning inventories. We are scheduled to receive 10 units of A in week 3, 20 units of B in week 7, 40 units of F in week 5, and 60 units of E in week 2; there are no other scheduled receipts. If 20 units of A are required in week 10, use the low-level-coded bill-of-materials (product structure tree) to find thenecessary planned order releases for all components.arrow_forwardAs the production planner for Xiangling Hu Products, Inc., you have been given a bill of material for a bracket that is made up of a base, 2 springs, and 4 clamps. The base is assembled from 1 clamp and 2housings. Each clamp has 1 handle and 1 casting. Each housing has 2 bearings and 1 shaft. There is no inventory on hand. Your boss at Xiangling Hu Products, Inc., has just provided you with the schedule and lead times for the bracket. The unit is to be prepared in week 12.The lead times for the components are bracket (1 week), base (1 week), spring (1 week), clamp (1 week), housing (3weeks), handle (2weeks), casting (4weeks), bearing (1 week), and shaft (1 week).

- One unit of A is made of two units of B and one unit of C. B is made of three units of Dand one unit of F. C is composed of three units of B, one unit of D, and four units of E.D is made of one unit of E. Item C has a lead time of one week; Items A, B, E, and F havetwo-week lead times; and Item D has a lead time of three weeks. Lot-for-lot (L4L) lot sizingis used for Items C, E, and F; lots of size 20, 40, and 160 are used for Items A, B, andD, respectively. Items A, B, D, and E have on-hand (beginning) inventories of 5, 10, 100,and 100, respectively; all other items have zero beginning inventories. We are scheduledto receive 10 units of A in Week 3, 20 units of B in Week 7, 40 units of F in Week 5, and60 units of E in Week 2; there are no other scheduled receipts.

Items A, B, and C use lot-for-lot (L4L) as their lot-sizing technique, while D, E, and F require multiples of 50, 100, and 100, respectively, to be purchased. B has scheduled receipts of 30 units inperiod 1. No other scheduled receipts exist. Lead times are one period for items A, B, and D, and two periods for items C, E, and F. Gross requirements for A are 20 units in period 1, 20 units in period 2, 60 units in period 6, and 50 units in period 8. Find the planned order releases for all items.arrow_forward
