Material Flow System
� Manufacturing Process includes three basic inputs :
1. Men
2. Machines 2. Machines
3. Materials
� Flow of Material :
Product Layout - Short & Smooth
Process Layout - Long & Complex
Material Flow System
Material Flow System is divided in two parts :
1. Horizontal Flow System
2. Vertical Flow System
Horizontal Flow System
� The Horizontal Flow Systems are devised in the
single story building when the flat floor area is
available.
In this system, the starting point is the receiving � In this system, the starting point is the receiving
(R) of raw material and the terminal point is
shipment (S) of finished goods.
� In between these two points, the materials move
from one work station to another for the
processing.
Horizontal Flow System
Is denoted by the alphabetic letters :
1. “I” type Flow :-
� Shortest route .
� Must have roads on � Must have roads on
both side.
� Plant area has long lengths But short width.
� Difficulty in returning empty containers.
� Absence of rushing of outside transportation.
� Unsuitable for longer production line.
Horizontal Flow System
Is denoted by the alphabetic letters
2. “L” type Flow :-
Horizontal Flow System
3. “U” type Flow :-
� One side road link will
be required.be required.
� Less difficulty in returning the empty containers.
� Possibility of rushing of outside transportation.
� Suitable for longer production line.
� Requires square like floor area.
Horizontal Flow System
4. “S” or inverted “S” type of Flow :-
� Requires roads on both
side.side.
� Absence of rushing of
outside transportation.
� Requires square like floor area.
� Difficulty in returning empty containers.
� Suitable for longer production lines.
Horizontal Flow System
5. “O” type Flow :-
� One side road facility
is required.
Heavy rush of outside � Heavy rush of outside
transportation.
� Easy in returning empty containers.
� Requires square like floor area.
� Suitable for longer production line.
Horizontal Flow System

7. “I” and “S” type Flow :-
Horizontal Flow System
8. “I” and “O” type Flow :-
Vertical Flow System
� The vertical Flow System arises in case of multi story
buildings.
� Multi storey building are used where limited land area is
available and the processing is done on light materials available and the processing is done on light materials
with the help of light machines.
Vertical Flow System
� Important Vertical Flow Systems :-
TYPES OF PLANT LAYOUTS
1. Product or Line layout
2. Process or Functional layout
3. Fixed Position or Project layout
4. Combination layout (Mixed layout)
1. PRODUCT OR LINE LAYOUT
ADVANTAGES OF PRODUCT LAYOUT
1. Low cost material handling
2. Smooth and uninterrupted operations
3. Continuous flow of work
4. Optimum use of floor space4. Optimum use of floor space
5. Shorter processing time
6. Simple and effective inspection of work
DISADVANTAGES:
PRODUCT LAYOUT
1. High initial capital investment
2. Heavy overhead charges
3. Lesser flexibility
2.PROCESS LAYOUT
Product B :
Product A :
ADVANTAGES OF PROCESS
LAYOUT
1. Lower initial capital investment
2. The overhead cost are relatively low
3. Supervision can be more effective and specialised
4. Greater flexibility 4. Greater flexibility
DISADVANTAGES OF PROCESS
LAYOUT
1. Material handling costs are high due to backtracking
2. More skilled labour is required
3. More frequent inspection is needed
COMPARISON BETWEEN PRODUCT
AND PROCESS LAYOUT
PRODUCT LAYOUT
1. Investment is high
2. Space requirement is more
3. Manufacturing time
required is more
PROCESS LAYOUT
1. Investment is less
2. Space requirement is less
3. Manufacturing time required
is lessrequired is more
4. Material handling is
maximum
5. Flexibility is high
is less
4. Material handling is minimum
5. Flexibility is less

6.Inspection is not required at
every stage
7. More skilled labours are

8. Supervision is not required
3.FIXED POSITION OR PROJECT LAYOUT
MANUFACTURING OF SHIP
ADVANTAGES OF FIXED
POSITION LAYOUT
1. It saves time and cost involved on the movement of
work from one work station to another
2. The layout is flexible as change in job design and
operation sequence can be easily incorporatedoperation sequence can be easily incorporated
3. It is more economical when several orders in
different stages of progress are being executed
simultaneously
DISADVANTAGES OF FIXED
POSITION LAYOUT
1. Production period being very long, capital investment
is very heavy
2. Very large space is required for storage of material
and equipment near the productand equipment near the product
