Part 1 Flashcards
Material requirements planning (MRP) does not include
the determination of how much to produce.
How much to produce (independent items) it determined by
Master production scheduling and is an input into MRP.
MRP is the link between
scheduling (master production schedule) and execution (purchasing and production activity control).
In converting independent demand items into dependent demand item requirements,
MRP will specify how much product comes from existing inventory versus purchasing or production, when orders need to be placed based on lead time constraints and when product needs to be delivered to support subsequent operations.
When determining the requirements of the material requirements plan, all except which of the following must be determined?
A. How much to order
B. How much to produce.
C. When to order.
D. When to deliver
B. How much to produce.
All expect which of the following are part of manufacturing lead time?
A. Queue time
B. Order time
C. Wait time
D. Move Time
B. Order time
_______ is part of the overall lead time of a product; however, it is not part of manufacturing lead time.
Order time
________ is the time it usually takes to produce an item.
Manufacturing lead time
Manufacturing lead time includes
queue time, setup time, run time, wait time, and move time.
A firm planned order is primarily used for what purpose?
to freeze the planned order against changes in quantity and time.
When material shortages or capacity problems arise, planners may opt to freeze the planned order against changes in quantity and in time. Doing so results in a
firm planned order.
Which of the following is considered to be an activity in physical distribution?
A. Material handling
B. Kanban size
c. Pull signals
D. Manufacturing routers
A. Material Handling
Physical distribution includes all activities associated with
physically moving goods. Material handling is required to physically move the goods.
Kanban size, pull signals, and manufacturing routers all pertain to
manufacturing.
Which form of scheduling is utilized when the last operation is scheduled for completion on the due date?
A. Detailed scheduling
B. Forward scheduling
C. Backward scheduling
D. Master scheduling
C. Backward scheduling
__________ schedules the last operation on the routing so that the completion date is the due date. Previous operations are scheduled back from the last operation.
Backward scheduling
The benefit of __________ approach is that it schedules back from the customer due date.
Backward scheduling
_____ schedules operations from the date that the order was received regardless of the due date.
Forward scheduling
________ is a manufacturing plan that forms the link between sales and production, but it is not a scheduling technique used to schedule shop orders.
Master scheduling
_________ is not a scheduling technique used to schedule shop orders.
Detailed scheduling
All except which of the following would best define dependent demand?
A. Demand derived from present demand
B. Demand dependent on demand for a higher level assembly
C. Demand that is calculated
D. Demand dependent on the forecast
D. Demand dependent on the forecast
_______ is demand that is directly related to or derived from the bill-of-material structure for other items or end items. Such demands are therefore calculated and need not and should not be forecast.
Dependent demand
A given inventory item may have
both dependent and independent demand at any given time. For example, a part may simultaneously be the component of an assembly and sold as a service part.
__________ is calculated based on demand for higher level assemblies and demand derived from present demand.
Dependent demand.
Capacity requirements planning (CRP) is concerned with all except which of the following?
A. Validating the capacity for the MPS
B. Individual orders and work centers
C. Estimating work center loads
D. Detailed scheduling
A. Validating the capacity for the MPS.
Validating the capacity for the MPS is handled through
rough-cut capacity planning (RCCP).
_______ is concered with very detailed scheduling for individual orders at each work center to calculate work center loads.
Capacity requirements planning (CRP)
Production planning is generally a direct input into
Master production scheduling
_________ are developed at aggregate levels (monthly, product family levels).
Production plans
_________ are agreed-upon manufacturing plans for manufacturing, shipping, and inventory/backlog. From these plans, the master scheduler develops a detailed master production schedule that focuses on weekly end product output.
Production plans
Rough cut capacity planning supports the __________ by verifying the availablity of resources.
master production schedule
__________ is used to plan the organization’s flow of material from the master production schedule
Material requirements planning
____________ supports the material requirements plan by ensuring the required labor and machine resources are available.
Capacity requirements planning
What manufacturing environment assembles multiple end items from standard components?
Assemble-to-order ATO
______________ environments focus on creating many end items from components that can be manufactured and stocked in anticipation of customer goods.
Assemble to order
__________ schedule is generated based on actual customer orders.
Assemble to order
Make-to-stock (MTS) environments make and sell products from a
finished goods inventory.
Engineer-to-order (ETO) environments make products b tased on
the customer’s specifications.
Make-to-Order (MTO) environments wait to make products until
they are ordered.
The rate at which the system generates product is
throughput.
Work center process type is also called
job shop or intermittent manufacturing
Batch process type is also called
batch flow or lot manufacturing
