Abstract
 To improve the productivity of any organization, Plant layout plays a major
role.
 Plant layout design is the most effective arrangement of physical facilities to
allow the greater efficiency.
 In this presentation present that , CRAFT is used for improvement of existing
layout in crane manufacturing industry.
 After all literature and collection of data gather, Plant layout is critically studied
and found Distance matrix, cost matrix, flow matrix by perceived flow of
material in plant layout.
 Existing layout material handling cost was found.
 After interchanging pair wise departments, it was found that material handling
cost reduced.
 Further, Apply Space-relationship analysis of SLP to utilize space and it was
found that material handling cost was further reduced.

Introduction
• One of the main goals of manufacturing system is the maximization of its
productivity.
• Depend upon factor like complexity of the product made, quality of the raw
material, complexity of the manufacturing process, arrangement of work station.
• The challenge of determining best arrangement of workstations is one of the
element has a great impact on system performance.
•It is known as “ Facility layout Problem”.
•The designing of a new plant layout means to achieve remarkable improvement
in efficiency, manufacturing cost, lead time, travelling distance and overall
production cost and it is done by reallocating the equipment’s positions in the
layout.

 Work Process in a company:
Fig. Work process in a company.

 Component used in Crane manufacturing:
Fig. EOT Double girder crane

 Hook – To lifted load which connects to the hoist.
 Hoist – what makes the lift and holds , raises , or lowers the load using wire
rope. It can be manually powered, with electricity or with pneumatic.
 Trolley – supports the hoist and moves horizontally along the crane bridge , to
position the hoist and hook , prior to picking up and lowering a load. It can be
design in an under running or top running design:
 Bridge – load-bearing beam that runs the width of the building. Primary
structural component connects the runways and moves the hoist forward and
backward using a trolley.
 Runway – what the bridge crane travels on to move the crane up and down the
bays.
 Runway rail or tracks – Rail supported by the runway on which the crane
travels.
 End truck – Located on either side of the bridge, it move the bridge up and
down the runway utilizing a series of wheels that ride on the rail.
 Bumpers – design to absorb crane’s energy and reduce impact bringing the
crane to rest in a controlled manner and minimizing forces when the crane
reaches the end of its travel.

 Controls – typically mounted in a panel on the crane or hoist and the pendant
or remote radio console allows the operator to run the crane. It’s operate drive
and hoist motors and can control VFDs to control hoist speed for precise load
positioning.
 Electrification – Insulated conductor bars or festoon systems bring power to
the crane from the building.

 Company is manufacturing a Component like Bridge structure and Hoist.
 Other raw material or component is pursuing from market.

 Plant layout???
- Floor Plan of the physical facilities which are used in Production.
- refers to the generation of alternatives plans for the arrangement of physical
facilities and selects one which minimizes distance between departments.
 Objectives of good plant layout:
1. Minimize investment of equipment
2. Minimize production time
3. Utilization of existing space most effectively.
4. Minimize material handling cost.
 Classification of layout:
(1) Process Layout
(2) Product Layout
(3) Group Layout
(4) Fixed Position Layout
 Oswal Used combinational Layout.

Problem definition
 By observing , I found that in crane manufacturing plant .
 There are several type of problems present :
Fig. Initial layout with Material flow and process

Fig. Press/Drill/Painting area

 Problems:
1. High Material Handling Cost.
2. Size of Plate cutting area and Dispatch area, Press/Drill/Painting area,
Sheare/Bending/Drill Machine area is more.
3. Size of Assembly area or Fabrication area is small.
4. Flow is not smooth because of obstacle present on way of transportation in
Assembly or Fabrication area.
5. Entering of raw material from Receiving area, Lathe Machine Department and
dispatching of finished product from same gate in Assembly or Fabrication
area, which will increase complexity in process.

Aim And Objectives
 Aim:
To Improve existing layout of Crane manufacturing Industry using CRAFT and
SLP.
 Objectives:
 To minimize material handling cost by minimizing distance travelled by
material between Sheare/Bending/Drill/Machine area and Press/Drill/Painting
area.
 To utilize of space by reducing size of Plate cutting area, Sheare/Bending/Drill
Machine area, Press/Drill/Painting area and increasing size of Assembly or
Fabrication area.
 To provide a smooth material flow by removing obstacle present on the way of
Transportation in Assembly or Fabrication area.
 To reduce complexity in process by providing Separate gate for entering raw
material and dispatching finished product in Assembly or Fabrication area.
 To suggest a new optimum layout.

Find From Literature survey
 There are different methodology adopted by researcher like BLOCPLAN,SLP,
CRAFT,ALDEP,CORELAP.
 Systematic Layout procedure(SLP) is a manual method which is used for Small
manufacturing unit also its take a large time for improvement.
 This disadvantage of SLP is overcome by Computerized method.
 ALDEP and CORELAP are Computerized method. Both are constructive type
algorithm.
 CRAFT is a used for improvement for existing layout facility in any
organization or manufacturing company.

Methodology
Layout Design Procedure:
1. Manual Method: Travel Chart, SLP
2. Computerized Method: Constructive type ( ALDEP, CORELAP )
Improvement type ( CRAFT )
 Computerized Relative Allocation of Facilities Technique (CRAFT)
• Developed by Armour and Buffa.
• Widely used than ALDEP and CORELAP.
• Improvement type algorithm.
• Start with an initial layout and improves layout by interchanging department pair
wise so the transportation cost is minimized.
• Heuristic algorithm.
 “It is a technique designed for solving a problem more quickly when classic
methods are too slow or for finding an approximate solution when classic methods
fail to find any exact solution.”

 CRAFT requirement:
1. Initial layout
2. Flow data
3. Cost per unit distance
4. Total number of such departments.
5. Fixed departments
Number of such departments
Location of those departments.
6. Area of departments.

CRAFT algorithm
1. Input.
2. Obtain the departments centroid.
3. Calculate the inter department rectilinear distance.
4. Calculate the initial cost of layout by multiplying flow matrix,
cost matrix , distance matrix.
5. CRAFT then consider all the possible two ways or three way
department based on Common border or equal area criterion and identifies the
best “exchange”.
6. Update the layout and calculate the new department centroid.
7. The above procedure is repeated until no further reduction in the cost can be
Obtained.

 Systematic Layout Planning Procedure (SLP)
 An organize approach developed by Muther.
 Received considerable publicity due to the success derived from its application
solving a large variety of layout problems.
 Referred to as systematic layout planning(SLP).
 From the figure, clear that once the appropriate information is gathered, a flow
analysis can be combined with an activity analysis to develop the relationship
diagram.
 The space relationship diagram is constructed by combining space
considerations with the relationship diagram.
 Based on the space-relation diagram, modifying considerations and practical
limitations, a number of alternative layouts are designed and evaluated.

Fig. Systematic layout planning procedure

 Collected Data:
1. Initial layout.
 I measured all area in meters by using Freemans open reel fibre measuring
tape.
Fig. Freemans open reel fibre measuring tape
 I prepared layout in AUTOCAD 2018 Shown in Figure 9.

2. Area of department
From the Initial layout I Prepared the list of department area.
Table. List of Area

3. Total Number of department: 13
4. Flow Matrix
 For number of trip per day I need a data from Inward and outward register.
From the colour and non consumable store’s inward register I obtain how many
trips or delivery of material is received from receiving area to receiving store
(Color and non consumable store and Electrical store , Fabrication area) per
day.
 I take in consider maximum trip per day in a month.

 From the above observation, I consider average 14 trips. From those trips I
obtain how many trips required for unloading material by Workers.
 From the Inward material I take the following data for obtain trips between
Receiving area and other Receiving store like Color and Non consumable store
and Electrical store, Fabrication area which it is shown in below table.

Table. Material received by receiving store

 From the receiving area to Lathe department, I obtained trips from inward
material store which it is shown in table .
Table. Material inward register in Lathe department

 For obtained trips between Color and Non consumable store and other area like
Press/Drill/Painting area, Assembly area, I take data from material withdrawal
register which it used in Color and Non consumable store by store in-charge. It
is shown in table .
Table. Material withdraw from Color and Non consumable store

 For obtained trips between Machines tools store and Plate cutting area,
Assembly area, Press/Drill/Painting area and Sheare/Bending/Drill
Machine area, I take data from material withdrawal register in Machine
tool store which it is shown in table.

Table. Material withdraw from Machine tool store

 They haven’t material withdrawal register for Electrical store. Further I visited
assembly area for obtain material movement between Assembly area and other
department like office, electrical store, Press/Drill/Painting area, Plate cutting
area, Sheare/Bending/Drill machine area, Lathe department, Storage of ready
component/semi finished area and Dispatch area.
 Also I noted down time for trips between Sheare/Bending/Drill machine area
and Press/Drill/Painting area, Assembly area. Also I understand purpose of
tools by asking question to worker for obtaining flow material.
 Based on data I obtained flow matrix shown in below table.

5. Cost matrix
 For that cost matrix, I observed that Supplier is supplying raw material by
using different resources like Truck, Mini Pickup Truck. Its material handling
cost depends on Supplier, fuel consumption and Driver salary not on company.
But Material unloading from different resources depends on Company.
 I take following data from company:
 Worker Salary/Month – Rs.7500
 Working day – 26
 Worker Salary/Day – Rs.288.46
 Working Hours/Day – 8 Hr
 Worker Salary/Working hour – Rs.36.06
 Office Staff Salary & Store in-charge Salary/Month – Rs.12000
 Office Staff Salary & Store in-charge Salary/Day – Rs.461.54

 I obtain 1 trip by using 10 Tonne EOT Crane and Hydraulic pallet truck.
 But here, I also observed that they are loading material on Hydraulic pallet
truck by using 5 tonne Ganity crane. But Movement of Crane in
Sheare/Bending/Drill Machine area doesn’t depend on Material handling cost
between two departments. So Here, I also observed that Hydraulic pallet truck
is used for carrying material from Sheare/Bending/Drill Machine area to
Assembly or Fabrication area.

•Net profit is found from company balance sheet

Table. Cost- Benefit Analysis (Material handling cost)

Result
 After Applying CRAFT, I found that new layout 19 is best layout from
observation and analysis.
 Material handling cost is reduced from Rs. 4450.34 per day to Rs. 3727.83 per
day. Material handling Distance is reduced from 1395.75 Meter to 1331.525
Meter.
 Reduction in material handling cost
= [(Existing layout cost - New layout cost) ×100] / Existing layout cost
= [(4450.34 – 3727.83) ×100] / (4450.34) = 16.23%.
 But here I observed that new layout 19 is not suggested because of unutilization
of space. For the utilization of space, SLP is used for the further improvement.

 After Applying Space-relationship analysis of SLP, I prepared new modified
layout. I observed that Material handling cost is reduced from Rs.3727.83 per
day to Rs.3677.19 per day.
 Material handling distance is reduced from 1331.525 Meter to 1312.38 Meter.
 Reduction in material handling cost
= [(Existing layout cost - New layout cost) ×100] / Existing layout cost
= [(4450.34 – 3677.19) ×100] / (4450.34) = 17.37 %.
 From the result, I found that New modified layout is best layout for Proposed.

 New Proposed layout:
Fig . Proposed layout

 From FPC ratio analysis, the ratio of proposed layout method > the ratio of
existing layout method.
 The proposed layout method is an improved one.
 From Cost-Benefit analysis found that New modified layout is more profitable
than existing layout.
Table. Summary of result

 The initial material handling cost is Rs.4450.34 per day.
 CRAFT algorithm was applied and it was found that material handling cost is
reduced to Rs.3727.83 per day(16.23%) after interchanging Press/Drill/Painting
area and Assembly or Fabrication area.
 SLP is used for further improvement by utilization of space and found that
material handling cost is reduced to Rs.3677.19 per day(17.37%).
 New modified layout is a best proposed layout to suggest.
 Further benefits were:
 Increase productivity
 Low cost of product
 Reduction in efforts by assembly workers.
Conclusion

 5s is a best lean tool to suggest for crane industry to make clean and tidy by
removing obstacle and waste from floor space.
