PROCESS TECHNOLOGY AND

DESIGN PROCESSa specific combination of

machines, operators, work methods,materials, tools, and environmentalfactors that together convert inputs to

outputs PROCESS TECHNOLOGYmethods

and equipment used to manufacture aproduct or deliver a service

HARD TECHNOLOGYinvolves theapplication of computers, sensors,robots, & other mechanical & electronicaids

SOFT TECHNOLOGY

application ofcomputer software

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


4/23

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


5/23

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


6/23

TYPES OF PRODUCTION

PROCESS PROJECT

- Production process is one in which a

unique and usually large and complex

item is produced


7/23

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


8/23

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

Technology

MACHINE VISION

SYSTEMS

- Automatically

receive andinterpret an image

of a real scene to

obtain information

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 AND

WORKPLACE DESIGN


12/23

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


13/23


14/23

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.


15/23

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.


16/23

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


17/23

DESIGN OF PROCESS

LAYOUTS In designing process layouts, we are

concerned with the arrangement of

departments relative to each other


18/23

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

PROCESS

MANAGEMENT

21/23

PROCESS CONTROL

CONTROLthe continuing process ofevaluating performance and taking

corrective action when necessary

THREE COMPONENTS1. a standard goal

2. a means of measurement of

accomplishment3. a means of comparing actual

results with the standard along with

feedback to form the basis for


22/23

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.
