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
