PROCESS TECHNOLOGY AND
DESIGN PROCESSa specific combination of
machines, operators, work methods,materials, tools, and environmentalfactors that together convert inputs to
outputs PROCESS TECHNOLOGYmethods

CLASSIFICATION OF PRODUCTION
SYSTEMS AND PROCESSES
MAKE-TO-ORDERproduce only inresponse to order
- produce a larger variety of
products in smaller quantities
MAKE-TO-STOCKbuild inventories
for future sales

TYPES OF PRODUCTION
PROCESS
CONTINUOUS
FLOW
- Are characterized
by high productionvolume and a high
degree of product
standardization
MASS,OR
ASSEMBLY-LINE
- Are used for high-
volume productionof discrete parts

TYPES OF PRODUCTION
PROCESS BATCH, OR
INTERMITTENT
- Production process
are used forproducing lots of
similar products
- Labor skills are
necessary to set upmachines and
perform a wider
variety of tasks
during production
JOB-SHOP
- Production process
produce a wide
variety and smallquantity of
specialized products

TYPES OF PRODUCTION
PROCESS PROJECT
- Production process is one in which a
unique and usually large and complex
item is produced

THREE TYPES OF PROCESS
TECHNOLOGY MANUAL TECHNOLOGYuses no
machinery to perform manufacturing
or assembly tasks
MECHANIZED TECHNOLOGYutilizes machines that are under
human control
AUTOMATED TECHNOLOGYusescomputers to control the process

Automation and Advanced
Technology
NUMERICAL
CONTROLLED
- Enable the
machinists skills tobe duplicated by a
computer program
that is stored on a
computer
ROBOTICS
- A programmable
machine designed
to handle materialsor tools in the
performance of a
variety of stock

PROCESS PLANNING AND
DESIGN To design a process, several activities must be
performed
1. identify the individual components of the product
and their order of assembly (PRODUCT
ANALYSIS)2. Identify the sequence of production steps
required to fabricate each component (PROCESS
ANALYSIS)
3. Select the appropriate technology andequipment to accomplish each processing step (
PROCESS SELECTION)
4. Design work methods for each

FACILITY LAYOUT
Refers to the specific arrangement ofphysical facilities
It is necessary whenever:
1. a new facility is constructed
2. there is a significant change in
production or throughout volume
3. a new product is introduced
4. different process and equipment are
installed

Examples of product layout
Service organization that providehighly standardized services
Course registration in a college or
university
Note: whenever little variety and
personalization of services is offeredand the volume of demand is high, a
product layout is used.

LAYOUT PATTERN
GROUP LAYOUT
- Process layouts, which
dominate batch-
production facilities,
result in a largenumber of setups for
different parts, as well
as high materials-
handling costs andhigh work-in process
inventory
- Example: offices
FIXED-POSITION
LAYOUT
- The construction of
large items, such as
heavy machine tools,airplanes, locomotives
is usually
accomplished in one
place rather thanmoving from one work
center to another tools
and components are
brought to one place
for assembly.

DESIGN OF PRODUCT
LAYOUT Continuous flow, assembly line, and
many batch-processing production
processes are all forms of product line
which can be defined as a fixedsequence of production stages, each
consisting of one or more machines or
workstations

DESIGN OF PROCESS
LAYOUTS In designing process layouts, we are
concerned with the arrangement of
departments relative to each other

DESIGN OF GROUP
LAYOUTS Involves three steps:
1. selection of part families
2. selection of machine groupings or
cells
3. detailed arrangement of the cells

corrective action when necessary

QUALITY CONTROL
POKA-YOKEa device that permanentlyprevents the recurrence of the defect it is
designed to eliminate
SUCCESSIVE CHECKING
design ofprocess that are physically impossible if
preceding processes have produced
defective parts
AUTOMATIONinvolves equippingmachines with automatic stopping devices
and other features that eliminate the
possibility that large quantities of defectives
will be produced.
