- One of the inputs to the MRP system is the forecast of demand for the end itemover the planning horizon. From the point of view of production, what advantagesare there to a forecasting system that smooths the demand (that is, providesforecasts that are relatively constant) versus one that achieves greater accuracybut gives “spiky” forecasts that change significantly from one period to the next?The following table lists the components needed to assemble an end item, lead times, and quantities on hand. Item End B C D E F G H LT (wk) 1 3 2 2 2 1 2 1 Amount on hand 0 10 9 25 11 32 3 0 a. If 18 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 b. An order for the end item is scheduled to be shipped at the start of week 14. 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 for this part either.)

- User Solutions, Inc.usersolutions.comExamine the features available from the system. Describe the use of the system for MRP planning and scheduling.5. Define a Master Production Schedule (MPS) and explain how it differs from a final assembly schedule. 6. Define Material Requirements Planning (MRP) and how it can benefit an organization. 7. Explain a bill of materials (BOM), bill of labor (BOL), and bill of resources (BOR) relate. 8. What are the components of an MRP record? 9. Explain the three lot-sizing methods, and under what circumstances each work best: a. Lot-for-Lot (LFL) b. Fixed Order Quantity (FOQ) c. Periodic Order Quantity (POQ) 10. What is capacity requirements planning (CRP)? PROBLEM 1. A company currently has no items in inventory. The demand for the next four months is 200, 400, 250 and 350 units. Determine the level production rate if a level strategy is selected with the goal of ending Period 4 with 100 units in inventory. 2. A company currently has no items in inventory. The demand for the next four months is 200, 400, 250 and 350 units. Assuming a level production rate of 250 units per month,…What level of planning (i.e MRP, MRP II, or ERP) would be needed to procure, manage, and control all of the automobile assembly processes? Would this improve production flows and capacity utilization?
- An end item’s demand forecasts for the next 10 weeks are 30,20, 35, 50, 25, 25, 0, 40, 0, and 50 units. The current on-handinventory is 80 units. The order policy is to produce in lots of100. The booked customer orders for the item, starting withweek 1, are 22, 30, 15, 9, 0, 0, 5, 3, 7, and 0 units. At present,no MPS quantities are on-hand for this item. The lead time is2 weeks. Develop an MPS for this end item.The difference between a gross material requirementsplan (gross MRP) and a net material requirements plan(net MRP) is:a) the gross MRP may not be computerized, but the netMRP must be computerized.b) the gross MRP includes consideration of the inventoryon hand, whereas the net MRP doesn’t include theinventory consideration.c) the net MRP includes consideration of the inventoryon hand, whereas the gross MRP doesn’t include theinventory consideration.d) the gross MRP doesn’t take taxes into account, whereasthe net MRP includes the tax considerations.e) the net MRP is only an estimate, whereas the gross MRPis used for actual production scheduling.17 To minimize the effects of uncertainty due to lead times, MRP systems incorporate ______. a safety stock b safety lead time c planned released orders d increase in production 18 A JIT system schedules ______. a parts b capacity c MPS d operations 19 Scheduling decisions have ______ time horizons. a long-term b intermediate-term c short-term d prolonged term
