-MRP is an acronym for Material Requirements Planning -MRP is used to determined the number of the parts & other materials needed to produce a product
Which of the following is NOT a lot sizing technique used in MRP Systems
-fixed time cost
which of the following is/are issues a master scheduler must consider:
-include all demand -never lose sight of the aggregate plan -be involved w/ customer order promising -be visible to all level of management -objectively trade off manufacturing, marketing, and engineering conflicts -identify and communicate all problems
Which of the following are sources of demand for products in a material requirements planning system?
-inter-department transaction -orders for specific components needed in repair -customer orders from sales personnel
Which of the following is/are a part of an MRP record?
-planned order receipts -gross requirements -net requirements
From the highest level planning at the top to the lowest level planning on the bottom, rank the following:
1) aggregate planning 2)master production schedule 3)material requirements planning
In industry, A bill-of-material also goes by the acronym (blank)
BOM
An (blank-blank-blank) system is a computer system that integrates application programs form the functional areas of the firm.
Enterprise resource planning
Finished goods purchased by individuals external to the organization are considered dependent demand item
False
The (blank-blank) 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 releases.
MRP Record
A least total cost lot sizing technique is a dynamic approach that continually looks for an optimal lot size where carrying costs & ordering costs are close to equal
TRUE
If a company has more unites in the master production schedule than firm customer orders, the residual is called?
available to promise
MRP systems tend to work best in companies where products are made in (blank) using the same productive equipment
batches
The master production schedule TYPICALLY deals w/ what type of item?
finished goods/end items
A bill-of-materials that uses differences in alignment to indicate the order of assembly of components is using which type of structure?
indented structure
At any point in time, an MRP system can reference the (blank-blank-blank) for information concerning parts availability to help meet gross requirements
inventory records file
When changes occur because of stock receipts and disbursements, scrap losses, wrong parts & cackled orders, the real-time file capturing these changes is called the:
inventory transactions file
The inventory records files contains an (blank-blank) data segment that contain a detailed detailed description of the item, lead time information, safety, stock level and other records.
item master
The(blank-blank-blank) lot sizing technique is a dynamic approach that adds ordering & inventory carrying costs for each trial lot size, divides the costs by the number of units, and chooses the lot size w/ the lower unit cost.
least unit cost
Setting planned orders to match the net requirements exactly is what type of lot sizing technique
lot-for-lot
a process that places all identical parts at the same level in the bills-of-materials simplifies computations. The process is known as (blank-blank-blank)
low-level coding
The step in the planning process from the master production schedule is called (blank-blank-blank)
material requirements planning
An item that can be produced & stocked as a subassembly often uses a (blank) bill-of-materials for planning.
modular bill -of-material
After finding requirements, the next step in the MRP explosion process references inventory on hand and schedule orders to calculate ( blank) requirements
net
a (blank) requirement is the amount needed when the projected available balance plus the scheduled receipts in a period are not sufficient to cover the (blank) requirements.
net gross
If a company has an MRP program that can reflect the exact
net change system
The file created by retracing a material requirement upward in the product structure to identify each parent item that crated the demands is called a (blank)record
peg
The bill-of-matiral fils is also known as
product tree & product structure file
an EOQ lot sizing technique will try to minimize the sum of which of the following costs given a fairly constant demand?
setup inventory holding
the ultimate goal of any MRP lot sizing approach is to balance the (blank) or (blank) costs and the ( blank) costs associated with meeting the net requirements generated by the MRP planning process.
setup order costs holding
A company production widgets only needs Part A for 40% of the widgets built. This company is likely using what type of bill-of-material?
super
Which of the following is NOT a part of the material requirements planning system?
supplier delivery schedule
The next level in the planning process down from an aggregate plan is called
the master production schedule
(blank)(blank) are a company's attempt to provide a controlled window of opportunity to make changes to the master production schedule.
time fences
which of the following is not a type of time fence described in the text?
variable
