Which of the following is an input to the master production schedule? Bill of materials (BOM) file Inventory records file Exception reports Planned-order schedules None of the above
None of the above
Which of the following files allows us to retrace a material requirement upward in the product structure through each level, identifying each parent item that created the demand? Planning bill of materials file Modular bill of materials file Super bill of materials file Exception report file Peg record file
Peg record file
A BOM file is also called which of the following? Product tree Stocking plan Inventory usage record Production parts plan Time bucket schedule
Product tree
A BOM file is often called a product structure file or product tree because it shows how a product is put together.
True
A lot-for-lot (L4L) lot sizing technique does not take into account setup costs or capacity limitations.
True
A master production schedule is an input to a material requirements planning (MRP) system.
True
Computing the quantity of each component that goes into a finished product can be done by expanding (or exploding) each item in a product structure file and summing at all levels.
True
MRP is a logical, easily understandable approach to the problem of determining the number of parts, components, and materials needed to produce each end item.
True
MRP is based on dependent demand.
True
MRP provides the schedule specifying when each part and component of an end item should be ordered or produced.
True
Net change MRP systems are "activity" driven.
True
The deeper one looks into the product creation sequence, the more the requirements of dependent demand items tend to become more "lumpy."
True
The master production schedule states the number of items to be produced during specific time periods.
True
The three main inputs to an MRP system are the bill of materials, the master schedule and the inventory records file.
True
Time fences are periods of time having some specified level of opportunity for the customer to make changes.
True
Which of the following is the net requirement using an MRP program if the gross requirement is 1,250 and the inventory on hand is 50? 1,200 1,300 1,150 2,450 None of the above
1,200
Which of the following is the planned-order release using an MRP program if the gross requirement is 670 and the inventory on hand is 600? 670 600 530 70 None of the above
70
Which of the following is an input file necessary to run an MRP system? Bill of materials (BOM) file Quality management report Exception reports Planned-order schedules Purchasing contracts
Bill of materials (BOM) file
MRP systems seek to achieve which of the following? Minimize lot sizes Determine the number of dependent demand items needed Relieve capacity bottlenecks Provide a yardstick for future improvements Improve on JIT methods
Determine the number of dependent demand items needed
One of the main purposes of a MRP system is which of the following? Track inventory levels Create productive capacity Decrease layers of management Develop schedules specifying when each component should be ordered or produced. Upgrade manufacturing's professionalism
Develop schedules specifying when each component should be ordered or produced.
"Projected available balance" is a term referring to unsold finished goods inventory.
False
An input to the material requirements planning (MRP) system is an exception report.
False
An output of MRP is a bill of materials (BOM) file.
False
In a net change MRP program, a change in one item will result in a completely new inventory plan and schedule for every item in the master production schedule.
False
Low level coding in MRP indicates the exact status of each item managed by the system in "real time."
False
MRP stands for Manufacturing Requirements Planning.
False
The MRP program performs its analysis from the bottom up of the product structure trees, imploding requirements level by level.
False
The economic order quantity (EOQ) lot sizing technique produces or acquires exactly the amount of product that is needed each time period with none carried over into future periods.
False
A product tree can do which of the following? Help to compute component usage Reduce product scrap Reduce labor overtime Reduce regular time labor Locate raw material supplies
Help to compute component usage
In a typical inventory status record which of the following would you not expect to see? Scrap allowance Order quantity Gross requirements Planned-order releases Lost items
Lost items
