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
