10. MRP, considering inventory position, bills of material, open purchase orders and lead times guarantees a feasible production plan if the inputs to MRP are accurate.

False

11. The bill of materials indicates how much material will be needed to produce the quantities on a given master production schedule.

False

13. The bill of materials contains information on lead times and current inventory position on every component required to produce the end item.

False

15. An assembly-time chart indicates gross and net requirements taking into account the current available inventory.

False

17. The gross requirements at one level of an MRP plan determine the gross requirements at the next lower level continuing on down to the lowest levels shown on the bill of material.

False

18. The gross requirements value for any given component is equal to the net requirements of that components immediate parent multiplied by the quantity per parent.

False

2. Low level coding represents items less than $18 per unit.

False

20. A net-change MRP system is one that is updated periodically but not less frequently than once a week.

False

22. A regenerative MRP system is one that is updated continuously - every time there is a schedule change.

False

25. Lot-for-lot ordering in MRP provides coverage for some predetermined number of periods using forecasted demand to extend beyond the orders already received for those periods.

False

26. MRP output reports are divided into two main groups - daily and weekly.

False

27. In MRP, EOQ models tend to be less useful for materials at the lowest levels than for upper level assemblies of the bill of materials since higher-level assemblies have larger dollar investments.

False

3. Independent demand tends to be more lumpy than dependent demand meaning that we need large quantities followed by periods of no demand.

False

30. MRP II is simply an improved version of MRP that processes faster and can plan for a larger number of end items.

False

32. Capacity requirements planning (CRP) is an important feature in MRP+.

False

34. As long as a forecast is plus or minus 10%, MRP works well.

False

38. MRP really doesnt apply to services since raw material isnt required.

False

7. Net requirements equal gross requirements minus safety stock.

False

1. MRP works best if the inventory items have dependent demand.

True

12. A bill of materials contains a listing of all the assemblies, parts, and materials needed to produce one unit of an end item.

True

14. The inventory records contain information on the status of each item by time period.

True

16. MRP II did not replace or improve the basic MRP.

True

19. The term pegging refers to identifying the parent items that have generated a given set of material requirements for a part or subassembly.

True

21. One reason that accurate bills of material are important is that errors at one level become magnified at lower levels because of the multiplication process used by MRP.

True

23. One of the primary output reports of MRP concerns changes to planned orders.

True

24. Safety time is sometimes used in MRP rather than safety stock quantities.

True

28. Load reports show capacity requirements for departments or work centers which may be more or less than the capacity available in that work center.

True

29. ERP began in manufacturing organizations but has spread into service organizations.

True

31. Lot-for-lot ordering in MRP eliminates the holding costs for parts that are carried over to other periods.

True

33. Project Management approaches can help in a conversion to an ERP system.

True

35. ERP represents an expanded effort to integrate standardized record-keeping that shares information among different areas of an organization.

True

36. Back flushing takes place after the production has been completed.

True

37. Before a schedule receipt can take place, and order must be placed with a vendor.

True

39. ERP implementation requires support and a direct mandate from the CEO because it impacts so many different functional areas.

True

4. Lumpy demand for components results primarily from the periodic scheduling of batch production.

True

40. ERP automates the tasks involved in performing a business process, such as order fulfillment and financial reporting.

True

5. MRP is used within most MRP II and ERP systems.

True

6. The master production schedule states which end items are to be produced, in addition to when and how many.

True

8. The master schedule needs to be for a period long enough to cover the stacked or cumulative lead time necessary to produce the end items.

True

9. Initially, a master production schedule - the output from MRP - may not represent a feasible schedule.

True
