should facilitate effective supervision
over workers and finally number 10 the
principle of satisfaction a good layout
should boost up employee morale by
providing them with maximum work
satisfaction now let's look at the four
commonly studied types of layout in a
production plant one process layout or
functional layout to product layout or
line layout three combination layout for
fixed position layout we will now
discuss about them in details let's
start with process layout or functional
layout in process layout all machines
performed similar types of operations
are grouped together at one location
examples all lathes all milling all
shaper etc are grouped at one location
will be clustered in like groups thus in
process layout the arrangement of
facilities are grouped together
according to their function in this
figure of the process layout or
functional layout we can see that all
the drilling machines milling machines
laid machines shaper machines are
grouped together separately in
particular areas they are not arranged
according to the sequence of operations
for a product product layout or line
layout if all the processing equipment
and machines are arranged according to
the sequence of operations of the
product the layout is called product
type of layout in this type of layout
only one product of one type of products
is produced in an operating area in this
figure we can see a product layout or
line layout where machines are arranged
in a line according to the sequence of
operations of the product combination
layout it is also called the hybrid or
mixed type of layout usually a process
layout is combined with the product
layout for example refrigerator
manufacturing uses a combination layout
process or functional layout is used to
produce various operations like stamping
welding heat treatment are carried out
in different work centers the final
assembly
of the product is done in a product type
layout in this figure we can see a
combination layout where the individual
parts of the product goes through all
required processes using a process
layout then all these processed parts
are assembled together in a product
layer to form the final product the
fixed position layout in fixed position
layout the material or major components
remain in a fixed location and tools
machinery men and other materials are
brought to this location examples
include the construction of bridges
ships large airplanes locomotives large
machinery etc in this figure we can see
the fixed position layout designed for
the construction of an airplane where
all necessary parts men machine and
materials are brought to the location of
construction of the product this type of
layout is used if the product being
manufactured cannot be easily moved
during production now that we have
discussed about them in details let's
look at the advantages and disadvantages
of different types of layouts the
advantages first process layout or
functional layout flexibility of
equipment and personnel variety of job
makes the job challenging and
interesting supervisors will become
highly knowledgeable about the functions
under their departments higher
utilization of production facilities
product layout or line layout reduced
material handling cost due to straight
flow material handling systems
simplified production planning and
control small amount of work in process
inventory unskilled workers can learn
and manage the production perfect line
balancing which eliminates bottlenecks
combination layout flexibility for more
complex products better utilization of
floor space and less backtracking
material flow fixed position layout it
involves least movement of materials
there is maximum flexibility for all
sorts of changes in product and process
a number of quite different projects can
be taken with the same layout now the
disadvantages or limitations of using
each of these layouts are as follows
process layout or functional layout
backtracking and long movements of
materials reduced material handling
efficiency production planning and
control is difficult more space is
required lower productivity due to
number of setup product layout or line
layout lack of flexibility a change in
product may require the facility
modification large capital investment
dependence of the whole activity on each
part combination layout difficult for
workers to understand the work
arrangement is complicated fixed
position layout it involves high
equipment handling costs there appears
to be low utilization of labor and
equipment so we have learnt about plant
layout principles of plant layout and
the commonly known types of layout along
with the advantages and limitations of
using each of them in details in the
next video we will discuss in details
about materials flow patterns the
relationship between plant layout and
material handling and the material
handling activities and functions thank
