Lean Production
|
integrated activities designed to achieve high-volume, high-quality production using minimal inventories of raw materials, work-in-process, and finished goods
|
|
customer value
|
something for which the customer is willing to pay
|
|
waste
|
anything that does not add value from the customers perspective
|
|
value stream
|
value-adding and non-value-adding activities required to design, order, and provide a product from concept to launch, order to delivery, and raw materials to customers
|
|
waste reduction
|
the optimization of value-adding activities and elimination of non-value-adding activities that are part of the value stream
|
|
preventive maintenance
|
periodic inspection and repair designed to keep equipment reliable
|
|
group technology
|
a philosophy in which similar parts are grouped into families, and the processes required to make the parts are arranged in a specialized workcell
--eliminated movement and queue time between operations, reduces inventory, and reduces employees |
|
quality at the source
|
philosophy of making workers personally responsible for the quality of their output. Workers are expected to make the part correctly the first time and to stop the process immediately if there is a problem
--workers become their own inspectors and do their own maintenance |
|
The three lean layouts
|
-group technology
-quality at the source -just in time production |
|
JIT production
|
producing what is needed when needed and nothing more
--anything over the minimum is waste --typically applied to repetitive manufacturing --vendors ship several times a day --exposes problems otherwise hidden by inventory |
|
level schedule
|
a schedule that pulls material into final assembly at a constant rate
|
|
freeze window
|
the period of time during which the schedule is fixed and no further changes are possible
|
|
backflush
|
where parts that go into each unit are periodically removed from inventory and accounted for paged on production
|
|
uniform plant loading
|
smoothing the production flow to dampen the reaction waves that normally occur from schedule variations
|
|
Kanban
|
a signaling device used to control production
|
|
Kanban Pull System
|
an inventory or production control system that uses a signaling device to regulate flows
--requires determining the number of kanban cards (or containers) needed --each container represents the minimum production lot size --an accurate estimate of the lead time required to produce a container is key to determining how many kanbans are required |
|
value stream mapping
|
a graphical way to analyze where value is or is not being added as material flows through a process
--needs a full understanding of the business including production processes |
|
Kaizen
|
Japanese philosophy that focuses on continuous improvement
|
|
Types of waste
|
-overproduction
-waste of waiting time -transportation waste -inventory waste -processing waste -waste of motion -waste from product defects |
|
Components of a lean focused supply chain
|
-lean suppliers
-lean procurement -lean warehousing -lean logistics -lean customers |
