the BOM file is also known as

-product structure file -product tree

which of the following is/ are issues a master scheduler must consider

-trade off manufacturing engineering and marketing conflicts -be involved with customer promising -never lose sight of the aggregate plan

in industry Bill of materials goes by the acronym

BOM

the system __________ ___________ is kept on each item managed by the MRP system and includes gross requirements scheduled receipts available balances net requirements planned order receipts and order release

MRP record

which of the following is true about MRP

MRP- Material requirements planning MRP is used to determine the number of parts and other material needed to produce a product

if a company has more units in the master production schedule than firm customer orders the residual is called

available to promise - available units that are not committed to customer orders are called available promise

MRP systems tend to work best in companies where products are made in _________ using the same production equipment

batches

the master Production schedule is used to plan

end items

an _________ ___________ ____________ system is a computer system that integrates application programs from the functional areas of a firm

enterprise resource planning

true or false: finished goods purchased by individuals external to the org. are considered dependent demand items

false

a BOM that uses differences in alignment to indicate the order of assembly of components is using which type of structure

indented structure

a material requirements planning system interfaces with the master production schedule, bill of materials file and ___________ ________ ___________

inventory record file

the __________ ___________ _____________ lot sizing technique is a dynamic approach that adds ordering and inventory carrying costs for each trial lot size. divides the costs by the number of units, and chooses the lot size with the lowest unit count

least unit cost

setting planned orders to match the net requirements exactly is what type of lot sizing

lot for lot

an item that can be produced and stocked as a sub-assembly often uses a _____________ BOM for planning

modular

after finding gross requirements the next step in MRP explosion process references inventory on hand and scheduled orders to calculate _________ requirements

net

if a company has an MRP program that can reflect the exact status of each item in real time this program is called

net change MRP system

lot sizes are the part quantities issued in the planned order receipt planned _____________ section of an MRP schedule

order release

the file created by retracing a material requirement upward in the product structure to identify each parent item that created the demand is called a _________ record

peg

which of the following is/ are part of MRP record

planned order receipts gross requirements net requirements

the first step in the MRP explosion process is

retrieve the gross requirements for end items from the MPS

An EOQ lot sizing technique will try to minimize the sum of which of the following costs given fairly constant demand

set up inventory holding

____________ ______________ are companys attempt to provide a controlled window of opportunity to make changes to the master production schedule

time fences

when changes occur because of stock receipts and disbursements, scrap losses, wrong parts, and canceled orders, the real time file capturing these changes is called

Inventory transaction file - the inventory transaction file tracks inventory changes as they occur

the next level in the planning process after aggregate plan is called

MPS

In industry materials requirements planning also goes by the acronym

MRP

Super -a super bill of material allows components to be specified with a fractional usage

the inventory record file contains _______ _____________ data segment that contains a detailed description of the item, lead time info and safety stock levels

item master

if an item is quite __________ or _________ the master production schedule may include major sub assemblies and complex components

large expensive

a process that places all identical parts at the same level in the BOM simplifies computations, this is known as

low level coding

A ________ requirement is the amount needed when the projected available balance plus the the schedule receipts in a period are not sufficient to cover ________ requirements

net gross

the ultimate goal of any MRP lot sizing approach is to balance the _________ or _______ cost and the ____________ costs associated with meeting the net requirements generated by the MRP planning process

setup order holding

which type of time fence allows for changes to a specific product as long as parts are available

slushy

which of the following is nor part of the material requirements planning system
