TYPES OF LAYOUT
1. Process layout, or functional layout.2. Product layout, line processing layout or flow line
layout.3. Fixed position layout or static layout.4. Cellular manufacturing layout or hybrid layout.5. Combination layout or Hybrid layout.
PROCESS LAYOUT
It involves grouping together like machines in one department based upon their operational characteristics.
E.g.. Machines performing drilling operations are
installed in the drilling dept, machines performing casting operations are grouped in casting dept, and so on..
Machines in each dept attend to any product that is taken to them. These machines are therefore called as ‘General purpose machines’.
Work has to allotted in each department in such a way that no machines in any dept should be ideal.
In a batch production layout machines are chosen to do as many different as jobs possible. While grouping the machines according to the process type, certain principals have to be followed:
1) The distance b/w depts. must be shorter so as to avoid long distance movement of materials.
2) The departments should be located in accordance with the series of operations.
3) Convenience for inspection.
4) Convenience for supervision.

PROCESS LAYOUT FOR MEDICAL CLINIC
ADVANTAGES Reduced investments on machines as they
are general purpose machines. Greater flexibility in the production. Better & more efficient supervision is
possible through specialization. There are greater scope for expansion as the
capacities of different lines can be easily increased.
This type of layout results in better utilization of men & machines.
It is easier to handle breakdown of equipment by transferring work to another machines.
There is full utilization of equipment. The investment on equipment would be
comparatively lower.
There is greater incentive to te individual worker to increase his performance.
DISADVANTAGES: There is difficulty in the in movement of materials. This type of layout requires more floor space. There is difficulty in production control.
PRODUCT LAYOUT
It involves the arrangements of machines in one line, depending upon sequence of operations. In product layout, if there is a more than one line of production, there are as many lines of machines.
The emphasis here, therfore,is on special purpose
machines in contrast to the general purpose machines which are installed in the process layout.
The investment on straight line layout is higher than in the functional layout.
The product layout is followed in plants manufacturing standardized products on a mass scale such as chemical, paper, sugar, rubber, refineries & cement industries.

PRODUCT LAYOUT IN MANUFACTURING PRODUCT
ADVANTAGES There is mechanization of materials handling a &
consequently reduction in materials handling cost. This type of layout avoids production bottlenecks. There is economy in manufacturing time. The layout facilitates better production control. It requires less floor area per unit of production. WIP is reduced & investment thereon, minimized. Early detection of mistakes. There is greater incentives to a group of workers
to raise their level of performance.
DISADVANTAGES
Product layout is known for its inflexibility. This type of layout is also expensive. There is difficulty of supervision. Expansion is also difficult. Any breakdown of equipment along the
production line can be disrupt the whole system.
FIXED LAYOUT
Fixed position layout involves the movement of men & machines to the product which remains stationary. In this type of layout, the materials or major components remains in a fixed Location, & tools, machinery & men as well as other pieces of material are brought to this location.
The movement of men & machines is advisable as the cost of moving them would be lesser.
This is followed in manufacturing of bulky & heavy products, such as, construction of buildings, locomotives, ships, boilers, aircraft & generators.

ADVANTAGES Men & machines can be used for a wide variety of
operations producing different types of products.
The investment on layout is very small
The worker identifies himself with the products & takes pride in it when the work is complete.
The high cost of & difficulty in transporting a bulky product is avoided.
CELLULR MANUFACTURING (CM) LAYOUT
In CM, machines are grouped into a cells & cells function somewhat like product layout within a larger shop or process layout.
Each cell in the CM layout is formed to produce a single part family- a few parts all with a common characteristics, which usually means that they require the same machines & have similar machine settings.
ADVANTAGES Lower WIP inventories. Reduced materials handling cost. Shorter flow times in production. Simplified production planning ( materials & labour). Increased operators responsibilities. Improved visual control & fewer tooling changes,
therefore facilitating quicker set ups. Overall performance often increases by lowering
production costs & improving on time delivery. Quality also tends to improve.
DISADVANTAGES Reduced manufacturing flexibility & potentially
increased machine- down time ( since machines are contained to cells & may not be
used all the time) & finally duplicate pieces of equipment may be needed so that parts need not be transported b/w cells.
COMBINED LAYOUTA combination of process & product layout is known as
combined layout.
It is possible to have both types of layout in an efficiently combined form if the products manufactured are some what similar & not complex.
E.g.. In soap mfg plant, the machinery mfg soap is arranged on the product line principle; but ancillary services, such as heating, the mfg of glycerin, the power house, the water treatment plant are arranged on a functional basis.
