- a. One hundred twenty units of end item Z are needed at the beginning of week 7. Prepare a material requirements plan for component C. Take into account that on hand there are 40 units of Z,70 units of A, 100 units of B, and 30 units of C. Also, there is a scheduled receipt of 20 units ofcomponent C in week 4. Lead times are two weeks for Z and B, and one week for the other components. Lot-for-lot ordering will be used for all items b. Ninety-five units of end item E are needed at the beginning of week 7. Prepare a material requirements plan for component D. Take into account that 5 units of E are currently on hand, as well as50 units of B, 100 units of C, and 80 units of D. Also, 30 units of C have been outsourced and areexpected to arrive in week 4. Lead times are two weeks for E and C, and one week for the othercomponents. Assume lot-for-lot ordering except for D, where multiples of 40 must be used.arrow_forwardEach unit of A is composed of one unit of B, two units of C, and one unit of D. C is composed of two units of D and three units of E. Items A, C, D, and E have on-hand inventories of 20, 10, 20, and 15 units, respectively. Item B has a scheduled receipt of 10 units in Period 1, and C has a scheduled receipt of 50 units in Period 1. Lot-for-lot (L4L) is used for Items A and B. Item C requires a minimum lot size of 50 units. D and E are required to be purchased in multiples of 95 and 55, respectively. Lead times are one period for Items A, B, and C, and two periods for Items D and E. The gross requirements for A are 30 in Period 2, 30 in Period 5, and 40 in Period 8.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). Part 3 b) In what week do you need to start the castings? The castings need to be started in week enter your response here (enter your response as a whole number).arrow_forward
- Assume you are the manager of Assembly, Inc. You have just received an order for 27 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. Assume that the components are used only for this particular robot.arrow_forwardMontague Composite makes a unit A, which consists of two units of B, three units of C, and four units of D. C is composed of three units of D and two units of E. Items A, C, D and E have on-hand inventories of 10, 20, 30 and 40 units respectively. Item B has a scheduled receipt of 50 units in period 1, and C has a scheduled receipt of 90 units in period 1. Lot-for-lot sizing is used for items A and B. Item C requires a minimum lot size of 60 units. D and E must be purchased in multiples of 35 and 55 respectively. Lead times are one period for items A, B and C, and two periods for items D and E. The gross requirements for A are 180 in period 5, and 220 in period 8. Determine the planned-order releases for all items using template 2 (provided at the end of the paper)arrow_forwardThe BOM for product A is shown in Figure 2, and data from the inventory records are shown in Table 3. In the master production schedule for product A, the MPS start row has 150 units in week 3 and 300 in week 5. Develop the material requirements plan for the next 6 weeks for items B, C, and D.arrow_forward
