Chapter 6 - Manufacturing Processes Flashcards
The time needed to respond to a customer order.
Lead Time
Where inventory is position in the supply chain
Customer order decoupling point
A production environment where the customer is served “on-demand” from finished goods inventory.
Make-to-stock
A means of achieving a high level of customer service with minimum levels of inventory investment.
Lean Manufacturing
A production environment where preassembled components, subassemblies, and modules are put together
Assemble-to-order
A production environment where the products is built directly from raw materials and components in response to a specific customer order.
Make-to-order
Firms works with the customer to design and make the product.
Engineer-to-order
Total investment in inventory at the firm, which includes raw material, work-in-process, and finished goods.
Total Average Value of Inventory
An efficiency measure where the COGS is divided by the total average value of inventory.
Inventory turn
A measure of the number of days of supply of an item.
Days-of-supply
Mathematically relates inventory, throughput, and flowtime.
Little’s law
Material held by firm for future use
Inventory
Average rate (e.g. units/day) that items flow through process.
Throughput
The time it takes one unit to completely flow through a process
Flow Time
the strategic decision of selecting which kind of production processes to use to produce a product or provide a service.
Process selection
refers to deciding on the way production of goods or services will be organized. It has major implications for capacity planning, layout of facilities, equipment, and design of work systems
…occurs as a matter of course when new products or services are being planned.
Process selection
the product remains in a fixed location; equipment is moved to the product.
Project
similar equipment or functions are grouped together.
Workcentre (job shop)
a dedicated area where products that are similar in processing requirements are produced.
Manufacturing cell
work processes are arranged according to the progressive steps by which the product is made.
Assembly line
(assembly line only) the flow is continuous, such as with liquids.
Continuous process
A framework
depicting when the
different production
process types are
typically used,
depending on
product volume and
how standardized
the product is.
Product-process matrix
Time between successive units coming off end of an assembly line
Workstation cycle time
The problem of
assigning tasks
to a series of
workstations so that
the required cycle
time is met and idle
time is minimized.
Assembly-line balancing
The required order
in which tasks must
be performed in an
assembly process.
Precedence relationships
