Layout planning is deciding on the best physical arrangement of all resources that consume space within a facility.
Decisions about the arrangement of resources in a business are not made only when a new facility is being designed; they are made any time there is a change in the arrangement of resources, such as a new worker being added, a machine being moved, or a change in procedure being implemented.
Layout planning is performed any time there is an expansion in the facility or a space reduction.
he physical arrangement of production facilities. It is the configuration of departments, work centers and equipment in the conversion process. It is a floor plan of the physical facilities, which are used in production.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
2. PLANT LAYOUT
Plant layout refers to the arrangement of physical
facilities such as machinery, equipment, furniture etc.
with in the factory building or area in such a manner
so as to have quickest flow of material at the lowest
cost and with the least amount of handling in
processing the product from the receipt of material to
the shipment of the finished product.
3. DEFINITION
According to Riggs, “the overall objective of plant
layout is to design a physical arrangement that most
economically meets the required output – quantity
and quality.”
According to J. L. Zundi, “Plant layout ideally
involves allocation of space and arrangement of
equipment in such a manner that overall operating
costs are minimized.
4. DETERMINENTS OF PLANT LAYOUT
1. TYPE OF PRODUCT (size, shape and quality)
2. TYPE OF PROCESS (technology employed,
sequencing etc)
3. VOLUME OF PRODUCTIONS- (INCREASE OR
DECREASE)
5. IMPORTANCE OF PLANT LAYOUT
• It is long-term commitment
• It facilitates the production process, minimizes material
handling, time and cost, and allows flexibility of
operations
• It facilitates easy production flow, makes economic use of
the building, promotes effective utilization of manpower,
and provides for employee’s convenience, safety, comfort
at work, maximum exposure to natural light and
ventilation.
• It affects the flow of material and processes, labor
efficiency, supervision and control, use of space and
expansion possibilities .
6. OBJECTIVES OF PLANT LAYOUT
• Proper and efficient utilization of available floor space
• To ensure that work proceeds from one point to another point without any
delay
• Provide enough production capacity
• Reduce material handling costs
• Reduce hazards to personnel
• Utilize labor efficiently
• Increase employee morale
• Reduce accidents
• Provide ease of supervision and control
• Provide employee safety and health
• Allow ease of maintenance
• Allow high machine or equipment utilization
• Improve productivity
• To minimize cost of productions
• Better inter department relationship
7. FACTORS INFLUENCING PLANT
LAYOUT
1. Factory building :- The nature and size of the
building determines the floor space available for
layout. While designing the special requirements,
e.g. air conditioning, dust control, humidity control
etc. must be kept in mind.
2. Nature of product :- Product layout is suitable for
uniform products whereas process layout is more
appropriate for custom-made products.
8. 3. Production process :- In assembly line industries,
product layout is better. In job order or intermittent
manufacturing on the other hand, process layout is
desirable.
4. Type of machinery: General purpose machines are
often arranged as per process layout while special
purpose machines are arranged according to product
layout.
5. Repairs and maintenance :- Machines should be so
arranged that adequate space is available between
them for movement of equipment and people
required for repairing the machines.
9. 6. Human needs :- Adequate arrangement should be
made for cloakroom, washroom, lockers, drinking
water, toilets and other employee facilities, proper
provision should be made for disposal of effluents, if
any.
7. Plant environment :- Heat, light, noise, ventilation
and other aspects should be duly considered.
Adequate safety arrangement should also be made.
8. Management policies :- management policies
regarding size, quality, employee facilities and
delivery schedules should be considered while
deciding plant layout.
10. DYNAMICS OF PLANT LAYOUT
Increase in the output of the existing product
Introduction of a new product and diversification
Technological advancements in machinery, material,
processes, product design, fuel etc.
Deficiencies in the layout unnoticed by the layout
engineer in the beginning.
11. PRINCIPLES OF PLANT LAYOUT
• PRINCIPLE OF MINIMUM MOVEMENT
• PRINCIPLE OF FLOW
• PRINCIPLE OF SPACE
• PRINCIPLE OF SAFETY
• PRINCIPLE OF FLEXIBILITY
• PRINCIPLE OF INTERDEPENDENCE
• PRINCIPLE OF OVERALL INTEGRATION
• PRINCIPLE OF MINIMUM INVESTMENT
12. 1. PRINCIPLE OF MINIMUM
MOVEMENT
As far as possible materials and labour should be
moved over minimum distances.
13. 2. PRINCIPLE OF FLOW
The work areas should be arranged according to the
sequence of operations so that there is continuous
flow of materials without congestion.
The layout should allow for easy movement of
materials without interruption or delay.
14. 3. PRINCIPLE OF SPACE
All available cubic space should be effectively used
both vertically and horizontally.
15. 4. PRINCIPLE OF SAFETY
There should be consideration for safety and
convenience of workers.
There should be built in provision for the safety and
comfort.
16. 5. PRINCIPLE OF FLEXIBILITY
Layout should be designed in the manner that
production facilities can easily be rearranged when it
becomes necessary in future on account of expansion
and technological advancement.
18. 7.PRINCIPLE OF OVERALL
INTEGRATION
All the plant facilities and services should be fully
integrated into a single operating unit so as to
maximize efficiency and minimize costs of
production.
19. 8. PRINCIPLE OF MINIMUM
INVESTMENT
The layout should yield savings in fixed capital
investment through optimum utilization of available
facilities.
20. TYPES OF LAYOUTS
1. PRODUCT OR LINE LAYOUT
2. PROCESS OR FUNCTIONAL LAYOUT
3. FIXED POSITION OR LOCATION LAYOUT
4. COMBINED OR GROUP LAYOUT
21. 1.PRODUCT OR LINE LAYOUT
Under this, machines and equipments are arranged in
one line depending upon the sequence of operations
required for the product. The materials move from
one workstation to another sequentially without any
backtracking or deviation. Under this, machines are
grouped in one sequence. Therefore materials are fed
into the first machine and finished goods travel
automatically from machine to machine, the output
of one machine becoming input of the next.
22. e.g. in a paper mill, bamboos are fed into the
machine at one end and paper comes out at the other
end. The raw material moves very fast from one
workstation to other stations with a minimum work
in progress storage and material handling.
The grouping of machines should be done keeping in
mind the following general principles.
a)All the machine tools or other items of equipments
must be placed at the point demanded by the
sequence of operations.
b)There should no points where one line crossed
another line.
c)All the operations including assembly, testing,
packing must be included in the line
23. ADVANTAGES OF PRODUCT
LAYOUT
1. Low cost of material handling, due to straight and short
route and absence of backtracking.
2. Smooth and uninterrupted operations
3. Continuous flow of work
4. Lesser investment in inventory and work in progress
5. Optimum use of floor space
6. Shorter processing time or quicker output
7. Less congestion of work in the process
8. Simple and effective inspection of work and simplified
production control
9. Lower cost of manufacturing per unit
24. DISADVANTAGES OF PRODUCT
LAYOUT
1. High initial capital investment in special purpose
machine
2. Breakdown of one machine will hamper the whole
production process
3. Lesser flexibility as specially laid out for particular
product.
25. SUITABILITY OF PRODUCT
LAYOUT
1. Mass production of standardized products
2. Simple and repetitive manufacturing process
3. Operation time for different process is more or less
equal
4. Reasonably stable demand for the product
5. Continuous supply of materials
e.g. chemicals, sugar, paper, rubber, refineries, cement,
automobiles, food processing and electronics etc.
26. 2.PROCESS OR FUNCTIONAL
LAYOUT
In this type of layout machines of a similar type are
arranged together at one place. E.g. Machines performing
drilling operations are arranged in the drilling
department, machines performing casting operations be
grouped in the casting department. Therefore the
machines are installed in the plants, which follow the
process layout.
The work, which has to be done, is allocated to the
machines according to loading schedules with the object
of ensuring that each machine is fully loaded.
Used when the operations system must handle a wide
variety of products in relatively small volumes (i.e.,
flexibility is necessary)
27. The grouping of machines according to the process has
to be done keeping in mind the following principles
–
1. The distance between departments should be as short
as possible for avoiding long distance movement of
materials.
2.The departments should be in sequence of operations
3. The arrangement should be convenient for inspection
and supervision
28. ADVANTAGES OF PROCESS
LAYOUT
1. Lower initial capital investment in machines and
equipments. There is high degree of machine
utilization, as a machine is not blocked for a single
product
2. The overhead costs are relatively low
3. Change in output design and volume can be more
easily adapted to the output of variety of products
4. Breakdown of one machine does not result in
complete work stoppage
5. Supervision can be more effective and specialized
6. There is a greater flexibility of scope for expansion
29. DISADVANTAGES OF PROCESS
LAYOUT
Material handling costs are high due to backtracking
More skilled labour is required resulting in higher
cost.
Time gap or lag in production is higher
Work in progress inventory is high needing greater
storage space
More frequent inspection is needed which results in
costly supervision
30. SUITABILITY OF PROCESS
LAYOUT
Products are not standardized
Quantity produced is small
There are frequent changes in design and style of product
Job shop type of work is done
Machines are very expensive
Thus, process layout or functional layout is suitable for job
order production involving non-repetitive processes and
customer specifications and non-standardized products,
e.g. tailoring, light and heavy engineering products,
made to order furniture industries, jewelry etc.
31. 3.FIXED POSITION OR
LOCATION LAYOUT
In this type of layout, the major product being
produced is fixed at one location. Equipment, labor
and components are moved to that location. All
facilities are brought and arranged around one work
center. This type of layout is not relevant for small
scale entrepreneur.
32.
33. ADAVANTAGES OF FIXED POSITION
LAYOUT
1. It saves time and cost involved on the movement of
work from one workstation to another.
2. The layout is flexible as change in job design and
operation sequence can be easily incorporated.
3. It is more economical when several orders in
different stages of progress are being executed
simultaneously.
4. Adjustments can be made to meet shortage of
materials or absence of workers by changing the
sequence of operations.
34. DISADVANTAGES OF FIXED POSITION
LAYOUT
Production period being very long, capital investment
is very heavy
Very large space is required for storage of material
and equipment near the product.
As several operations are often carried out
simultaneously, there is possibility of confusion and
conflicts among different workgroups.
35. SUITABILITY OF FIXED POSITION LAYOUT
Manufacture of bulky and heavy products such as
locomotives, ships, boilers, generators, wagon
building, aircraft manufacturing, etc.
Construction of building, flyovers, dams.
shipbuilding, mining, drilling etc.
36. 4.COMBINED OR GROUP
LAYOUT
Certain manufacturing units may require all three
processes namely intermittent process (job shops),
the continuous process (mass production shops) and
the representative process combined process
In most of industries, only a product layout or
process layout or fixed location layout does not exist.
Thus, in manufacturing concerns where several
products are produced in repeated numbers,
Generally, a combination of the product and process
layout or other combination are found in practice.
37. e.g. for industries involving the fabrication of parts
and assembly, fabrication tends to employ the process
layout, while the assembly areas often employ the
product layout.
In soap, manufacturing plant, the machinery
manufacturing soap is arranged on the product line
principle, but ancillary services such as heating, the
manufacturing of glycerin, the power house, the water
treatment plant etc. are arranged on a functional
basis.
