CHAPTER 1: INTRODUCTION
1.1 Facilities Planning Definition
Facility planning is primarily involves managing the planning, programming, designing,
construction move-in, operation and maintenance of facilities to enable an organization to
achieve its goals.
During the past 10 years, the whole meaning for facilities planning has changed and has taken a
new meaning. In the past, facilities planning were primarily considered to be a science, but in
today’s competitive marketplace, a facility planning is a strategy. Nowadays different service
and manufacturing sectors such as governments, educational institutions, factories, and
businesses no longer compete against one another individually. These entities now align
themselves into cooperatives, organizations, associations and, ultimately, synthesized supply
chains to remain competitive by bringing the customer into process (Tompkins et al., 2010).
1.2 A Continues Improvement Facilities Planning Cycle
As shown in Figure 1.1, facilities planning has a continues improvement cycle which can be
applied in various places such as manufacturers, offices, hospitals, etc. Whether you are involved
in planning a new facility or planning to update an existing facility, the subject matter should be
of considerable interest and benefit (Tompkins et al., 2010).
1.3 Objectives of Facilities Layout
The objective of facilities planning is mainly the customer satisfaction, this will ensure that the
other objectives are in alignment with what drives the enterprise, namely revenues and profit
from customers.
The facilities planning objectives are:
Minimize material handling cost.
Minimize overall production time.
Utilize existing space most effectively.

1.4 Types of Facilities Layout
Facilities layout can be classified into basic and hybrid layout as shown in Figure 1.2 and Figure
1.3.
Basic types of facilities layouts:
Process: a layout that groups similar activities together in departments of work
centers according to the process or function that they perform.
Product: Product layouts arrange activities in a line according to the sequence of
operations that need to be performed to assemble a particular product.
Fixed-Position: Fixed-Position layouts are used in projects in which the product
is too fragile, bulky, or heavy to move like ships, houses, and aircraft.
Hybrid types of layouts:
Cellular: Cellular layouts attempt to combine the flexibility of a process layout
with the efficiency of a product layout. Based on the concept of group technology
(GT), dissimilar machines are grouped into work centers, called cells, to process
parts with similar shapes or processing requirements.
Flexible Manufacturing Systems: A flexible manufacturing system can produce
an enormous variety of items.
Mixed-Model Assembly Lines: Some manufacturers changed their forecasting
techniques to account for this.

1.5 Problem Statement
Emirates Metallic Industries Company (EMIC) is a manufacturer company which has two
branches in two different locations, one of them called service center and it occupies around
12,000m2 and the other branch which is named as EMIC 1 occupies around 7000m2. The
Company identified that there is a need to design an efficient layout in a new location with the
area of 130,000m2(260 x 500).
1.6 Project Motivation
Facility planning is considerably essential in manufacturing procedures due to their effect in
achieving an efficient product flow. It is estimated that between 20%- 50% of the total costs in
manufacturing is related to material handling. This cost can be reduced until 30% through an
effective facility planning (Balakrishnan, 2007). Proper analysis of facility layout design could
improve the performance of production line such as decrease bottleneck rate, minimize material
handling cost, reduces idle time, raise the efficiency and utilization of labor, equipment and
space. Figure 1.4 represents facility planning for manufacturing.
1.7 Project Objectives
The objective of this project is to get hands on experience working on a real life problem, aimed
at designing a layout for the combined two branches of EMIC in order to:
To utilize available space most effectively.
Minimize material handling cost.
Minimize overall production time.
Provide for employee convenience, safe, healthy, and comfort workplace.
1.8 Project Scope
This project is limited to the development of block layout alternatives for the manufacturing area
only.

Figure 1.4 Facility Planning for Manufacturing (Tompkins et al, 2010)
1.9 Constrains
The primary design constrains are:
Space requirements for equipment, materials, and personal requirements.
Considering health and safety of employees.
Efficiency rate of the new layout should be at least equal or better than efficiency of the
current layout.
1.10 Methodology
In order to achieve its objective, the project was carried out in two phases, phase I consist of
studying the current layout of EMIC company, defining the problem, and collecting data,
whereas phase II consist of collecting more detailed data and information, starting to design the
new plan of EMIC company, and finalizing and evaluating EMIC layout as Figure 1.5 illustrates.
1.11 Project Scheduling
To make this project meets the target completion date, Gantts charts were used to schedule the
activities. These charts were shown in Figure 1.6 and Figure 1.7.

CHAPTER 3: BACKGROUND KNOWLEDGE
In order to design a layout from scratch or develop an existing layout certain procedure should be
followed. Even though, it’s important to consider the flow between sections to achieve high
efficiency and decrease the cost in designing a layout but at the same time it’s essential to
consider productivity of the workers and provide healthy and pleasant work environment for
them. This chapter provides general knowledge about procedure of designing layout alternatives,
methods of evaluating these alternatives and selecting the best one. Also it provides background
about personal requirements and material handling.
3.1 Layout Procedures and Algorithms
There are different procedures and algorithms for designing layouts. These procedures and
algorithms can be classified into two main categories, which are construction type and
improvement type. The construction-type layout methods involve developing a new layout “from
scratch.” However, improvement procedures generate layout alternatives based on an existing
layout.
Examples of these layout procedures include Apple’s Plant Layout Procedure, Reed’s Plant
Layout Procedure and Muther’s Systematic Layout Planning (SLP) Procedure. Moreover, Layout
algorithms include Pairwise Exchange Method, Graph-Based Method, and computerized
algorithms such as Computerized Relative Allocation of Facilities Technique (CRAFT), and
Computerized Relationship Layout Planning (CORELAP) (Tompkins et al., 2010).
In this project SLP and CORELAP were used to develop layout alternatives. More details about
these techniques are described in following sections.
3.1.1 Muther’s Systematic Layout Planning (SLP) Procedure
SLP model developed by Muther (1973) is one of the most widely used Construction-layout
methods. This procedure is summarized in Figure 3.1. As shown in this Figure, SLP procedure
consists of the following major steps (Tompkins et al., 2010):
1) Information gathering
12
2) Flow and activity analysis
3) Constructing relationship diagram
4) Space determination
5) Constructing space relationship diagram
6) Modifying considerations and practical limitations
7) Develop layout alternatives
8) Evaluation
Figure 3.1 Systematic Layout Planning (SLP) Procedure (Tompkins et al., 2010)
13
Initial phase of SLP model is to collect data and information about the products and processes.
This stage requires gathering information about types and quantities of products to be produced,
process(s) and tools required for manufacturing these products, defining start time of production,
and defining how to move parts in and out.
The second step is to define flow between departments and relationship between different
activities. Flow among departments is one of the most important factors in the arrangement of
department within a facility. To evaluate alternative arrangements, a measure of flow must be
established. Flow maybe specified in a quantitative manner or qualitative manner. Quantitative
measure may include piece per hour, moves per day, or pounds per week. Qualitative measure
may range from an absolute necessity that two departments be close to each other to a preference
that two departments not be close to each other.
Flow may be measured quantitatively in terms of the amount moved between departments. The
most useful chart in flow measurement is from-to chart (Tompkins et al., 2010).
Furthermore, the flow may be measured qualitatively using the closeness relationships values
developed by Muther given in Table 3.1and developing a relationship chart showing the degree
of importance of having each department located adjacent to every other department as Figure
3.2 demonstrates.
Figure 3.2 Relationship Chart (Tompkins et al., 2010)
14
After defining the flow between departments using from-to chart and activity relationship chart,
the relationship diagram will be constructed. The Relationship Diagram positions activities
spatially. Proximities are typically used to reflect the relationship between pairs of activities.
The number of lines represents paths required to be taken in transactions between the
departments. The more lines represent the more interaction between departments. Each letter
represents a relationship and has been defining with specific number of lines as Table 3.2
illustrates.
Table 3.1 Closeness Relationship Values (Tompkins et al., 2010)
Table 3.2 Relationship Diagram (Tompkins et al., 2010)
The next step in SLP procedure is to define space requirements, which is most difficult
determination in facility planning. “Actually, the design for facility must serve the needs for
coming at least 5 to 10 years in the future” (Tompkins et al., 2010).The space required can be
determined through space requirement for individual workstations and individual departments.
After determining, the space requirement for each department the space relationship diagram
should be draw. Based on modifying considerations and practical limitations a number of layout
alternatives are developed and evaluated. The preferred alternative is then identified and
recommended.
3.1.2 CORELAP
15
Value Closeness
A Absolutely necessary
E Especially important
I Important
O Ordinary closeness okay
U Unimportant
X Undesirable
CORELAP is computerized relationship layout planning (Lee and Moore, 1967), which converts
qualitative input data into quantitative data and uses this information to determine the first
department to enter in the layout. Following departments are then added to the layout one at a
time, based on their level of interaction with departments already in the layout. The qualitative
flow input data are based on the relationship chart (Tompkins et al., 2003).
The user interface in our implementation of CORELAP is the spreadsheet. The user inputs data
through Microsoft Forms. To obtain a layout, the user is required to input the following: number
of departments, relationships weights, relationships cut-offs (in case of from-to chart), partial
adjacency value, and relationship or from-to chart. The user can then click the ‘SOLVE’ button
to generate the layout, which is displayed on the ‘Output’ worksheet. The ‘TCR’ (total closeness
rating) and the order of entry of departments in the layout are displayed besides the ‘REL’ or
‘from-to’ chart. The numerical closeness value and distance between the departments are also
shown. The layout score is displayed at the top in a cell below the partial adjacency value cell.
The first form provides user the opportunity to run an existing problem or a new problem. If the
user chooses ‘Existing Problem’ option then he or she can run the problem by pressing the
‘SOLVE’ button on the spreadsheet. The ‘New Problem’ option clears the spreadsheet of the
previous data and opens up the data input form.
In the data input form the user is required to specify the number of departments, partial
adjacency value, and to choose either from-to or REL chart option. On pressing ‘OK’ the
spreadsheet is updated. If the user chooses the from-to option, he or she has to provide cut-off
values. If the user chooses the ‘REL’ option then the user is prompted to specify weights of the
relationships.
The implementation requires the user to define weights in decreasing order A, E, I, O, U, and X.
The ‘X’ relationship has to be assigned a negative weight. The same applies to cut-off. The cut-
off values convert the flow scores into equivalent relationship values A, E, I, O, U, and X. The
‘OK’ button updates the spreadsheet and brings up a form asking user to input flow values or
relationship between the departments depending upon the previous choice of ‘from-to’ or ‘REL’
chart made by the user. Once the user has input the flows or the relationship values he or she can
16
press ‘OK’ to update the spreadsheet. Now the ‘SOLVE’ button can be clicked to run the
implementation and obtain a layout (Tompkins et al., 2003).
3.2 Evaluation of Layout Alternatives
There are several methods that can be used for evaluating layout and selecting the best
alternative among all. The two methods were used in this project to evaluate layout alternatives
are Layout Cost Method and Layout Efficiency Method. Moreover, these two techniques
described in following sections.
3.2.1 Layout Cost Method
In order to choose best layout alternative among all, list of criteria are required. One important
criterion is cost in choosing the best layout, so one way is to select the layout with minimum
total cost as equation 3.1 illustrates.
Total Layout Cost=∑i=1

c ij=¿¿ Cost of moving a unit load one distance unit from department i to department j
d ij=¿¿Distance from department i to department j
3.2.2 Layout Efficiency Method
One more important criteria in selecting the best layout is efficiency and can be computed using
Layout Efficiency Method which is shown in equation 3.2.

3.4 Personal Requirements
In every facility there are some necessities and requirements for individuals to provide them
welfare and comfort working environment. Therefore, the facilities planner must consider all
requirements while designing any facility. These requirements include:
Employee parking.
Storage of employee’s personal belongings.
Rest rooms.
Food services.
Health services.
3.4.1 Employee Parking
Design employee parking areas is very similar to design warehouses areas. In order to design
parking area number of automobiles, space required for each automobile, space available for
parking must be determined. Finally the best alternative which utilizes the space in an efficient
way should be selected. The size of parking space for an automobile can vary from 7×15 to
9.5×19, depending on the type of automobile and the amount of clearance to be provided. The
total area required for a parked automobile depends on the size of the parking space, the parking
angle and the aisle width (Tompkins et al, 2010).
3.4.2 Storage of Employee’s Personal Belongings
A place for storage of employee personal belongings should be provided between the employee
entrance and work area. Employees typically store lunches, briefcases, and purses at their place
of work.
The lockers may be located in a corridor adjacent to the employee entrance if clothes’ changing
does not take place. More commonly, locker rooms are provided for each sex even if clothes’
changing is not required. Each employee should be assigned a locker. For planning purposes, 6
ft2 should be allocated for each person using the locker room. Locker rooms are often located
18
along an outside wall adjacent to the employee entrance. This provides excellent ventilation and
employee convenience while not interfering with the flow of work within the facility (Tompkins
et al, 2010).
3.4.3 Restrooms
A restroom should be located within 200 feet of every permanent workstation. Decentralized
restrooms often provide greater employee convince than large, centralized restrooms. Access to
restrooms must be available to handicapped employees and must restrooms must be at ground
level. Separate rest rooms must be provided for each sex (Tompkins et al, 2010).
3.4.4 Food Service
The shifting of new facilities away from central business districts, the shortening of meal breaks,
OSHA forbidding consumption of foods where toxic substances exist, and the increased
important importance of fringe benefits have all contributed to making food services more
important to the facilities planner. Food services activities may be viewed by a firm as a
necessity, a convenience, or a luxury.
Food service facilities should be planned be considering the number of employees who eat in the
facilities during peak activity time. Kitchen facilities, on other hand, should be planned by
considering total number of meals to be served.
Food service requirements may be satisfied by any of the following alternatives:
1) Dining away from the facility.
2) Vending machines and cafeteria.
3) Serving line and cafeteria.
4) Full Kitchen and cafeteria (Tompkins et al, 2010).
3.4.5 Health Services
It is very difficult to predict facility requirements for health service. Some facilities have little
more than a well-supplied first aid kit, while other facilities have small hospitals. Therefore,
19
local building codes should be checked in establishing a facility’s requirements. The types of
health that may be provided within a facility include:
1) Pre-employment examinations,
2) First aid treatment,
3) Major medical treatment,
4) Dental care, and
5) Treatment of illnesses (Tompkins et al, 2010).
3.5 Material Handling
The design of the material handling system is an important component of the overall facilities
design. The layout design and the material handling system design are inseparable. The
integration between these two designs functions and the design of a new facility are particularly
critical.
Material handling means providing the right amount of the right material , in the right condition ,
at the right place , in the right position , in the right sequence , and for the right cost , by the right
methods (Groover, 2001).
3.5.1 Material Handling Equipment
Material handling equipment is equipment that relates to the movement, storage, control and
protection of the material, goods and products throughout the process of the manufacturing,
distribution, consumption and disposal. It’s the mechanical equipment involved in the complete
system.
There are many types of material handling equipment; the most important ones will be
mentioned here:
Pallets: the most common form of unitizing device.
Industrial trucks: usually referred to operator driven motorized warehouse vehicles
powered manually, by gasoline, propane or electrically .It assists the material-handling
system with versatility; they can go where engineered system cannot.
20
Forklift trucks are the most common example of industrial trucks but certainly aren’t the
extent of the category.
Conveyors: are another form of material handling. It can be used in multitude of ways
from warehouses to airports baggage handling systems .Some types of conveyors are
power and free , chain , towline and roller conveyor .
Monorails, hoists, and cranes: are generally used to transfer material from one point to
another in the same general area. Hoists are used to facilitate the positioning, lifting, and
transferring of material within a small area. They are generally provide more flexibility in
the movement bath than do conveyors; however, they do not have the degree of
flexibility provided by variable-bath equipment, such as industrial trucks.
Industrial vehicles: they represent a versatile method of performing material handling;
they are referred to as variable-bath equipment .They are generally used when movement
is either intermittent or over long distances (Tompkins et al, 2010).
3.6 Health and Safety
Health and Safety is an area concerned with protecting the safety, health and welfare of people
engaged in work or employment. It also protects co-workers, family members, employers,
customers, and many others who might be affected by the workplace environment.
3.6.1 Noise
Noise is a common occupational hazard in a large number of workplaces that affects millions of
workers. It’s generally defined as the unwanted sounds that distract the human being physically
and physiologically. Noise can interfere with employee’s ability to work by causing stress and
disturbing their concentration. However, it can cause accidents by interfering with
communication and warning signals. Practically most of human activities and technical
equipment associated with them generate excessive unpleasant sound. There are many factors
which produce noise in the workplace such as running engine, an operating machine tool, fans,
vibrating panels and so on. On the other hand, noise pollution can cause chronic health problems
and hearing loss.
3.6.2 Air Contaminants
21
Air contaminants take on many physical forms, and most people confuse these forms in everyday
language. The Safety and Health Manager should know the difference, for instance between
vapors and fumes. Although air is essentially gases, the contamination of that air can consist of
any of three states of matter solids, liquids or gases (Asfahl, 1999).
CHAPTER 4: DATA COLLECTION
A facility layout requires collecting data that provides answers to the following questions:
1) What is to be produced?
2) How are the products to be produced?
3) When are the products to be produced?
22
4) How much of each product will be produced?
5) For how long will the products be produced?
6) Where are the products to be produced?
This chapter presents the data collected from EMIC which helped us answering the above
questions.
4.1 Product Design
This section involves determination of which products to be produced and the detailed design of
individual products. The product design requires answers to the following questions (Groover,
2001).
1) What is to be produced?
2) How are the products to be produced?
In order to answer first question, Figure 4.1 indicates different types of EMIC’s products. The
flow chart has been shown in Figure 4.2 provided by engineers from EMIC explains the general
flow of material inside the factory from its initial stage until the final phase when the product is
produced.
4.2 Process Design
This section demonstrates determining how the product is to be produced, how the part will be
produced, which equipment will be used, and how long it will take to perform the operation.
23
Figure 4.1 Types of EMIC’s Products
Figure 4.2 Flow of Material Inside the Factory
4.2.1 Identifying Required Process
Determining the scope of a facility is a basic decision and must be made early in the facilities
planning process. Such decision is often referred to as “make-or-buy” decisions or “sourcing”
decisions.
Make-or-buy decisions are typically managerial decisions requiring input from finance,
industrial engineering, marketing, process engineering, purchasing, and perhaps human resources
among others. The make-or-buy decision process shown in Figure 4.3.
24
Figure 4.3 The make-or-buy Decision Process (Tompkins et al., 2010)
The make-or-buy decisions for all EMIC parts are shown in the part lists given in Tables 4.1-
4.9. As shown in these Tables, in addition to make-or-buy decision, each part list provides a
listing of the component parts of a product and includes part number, part name, number of parts
per product and drawing references. The following tables represent the part list for each EMIC’s
product.

4.2.2 Determining the Required Process
28
One important tool for determining the required manufacture process for each part is rout sheet.
A route sheet contains detailed description of processing and tooling that the parts go through.
As a sample the route sheets for two parts are shown in Figure 4.4 and 4.5 respectively.
Route Sheet Company: EMIC Part name: Drum 292 Produce: Metallic Product Part No.: 292
Figure 4.4 Route Sheet for Drum 292
Route Sheet Company: EMIC Part name: Drum 165 Produce: Metallic Product Part No.: 165
Figure 4.5 Route Sheet for Drum 165
29
4.2.3 Scheduling the Required Process
The only process selection information not yet documented is the method of assembling the
product. The Assembly chart provides the sequence in which the final product is produced. The
easiest method of constructing an assembly chart is to begin with the completed product and to
trace the product disassembly back to its basic components. As a sample Figures 4.6 and 4.7
represent the assembly chart for two products, namely, drum 292 and drum 165.
Figure 4.6 Assembly chart for Drum 292
30
Figure 4.7 Assembly chart for Drum 165
Although a route sheet provides information on production methods and assembly charts indicate
how components are combined, neither provides an overall understanding of the flow within the
facility. However, by superimposing the route sheets on the assembly chart, a chart results that
dose give an overview of the flow within the facility. This chart is an Operation Chart, which can
be complemented with transportation storage and delays (including distances and times when the
information is available(Trott,2012).As a sample Figures 4.8 and 4.9 represent the operation
chart for two products, namely, drum 292 and drum 165.

CHAPTER 5: CURRENT LAYOUTS
This chapter provides detail description about current layouts of EMIC’s branches, Service
Center and EMIC I which includes number of departments with their occupied area, flow
between departments, personal requirements, material handling, efficiency of layouts and health
and safety.
5.1 Service Center
The plan for Service Center is shown in Appendix I. This branch is consist of coil storage area,
ink storage area, new cutting area, old cutting area, coil cutting area, coating and printing
department, food section, food section store, coating store, design section and finish good store.
Table 5.1 indicates these sections with their occupying space.
As Figure 5.1 illustrates in Service Center production starts from coil storage area by receiving
coils from outside supplier. After receiving coils and placing them in the store, those coils will be
sent to cutting department in order to be cut to smaller coils or sheets. Finish products from
cutting section goes into three directions , approximately 75 percent goes for coating , around 5
percent for printing and about 30 percent will be moved directly to final store and delivering to
customer.
Food section is another department of service center, which receives large quantity of coats from
coating departments and produces small conserve cans for food.
Finally, all the products finished from cutting department, coating department and food section
sent to the store for packaging and transporting to the end customer.
5.2 EMIC I
The plan for EMIC I is shown in Appendix II. This division is consist of sheet cutting area, store
1 (finished goods from Service Center), assembly department, pressing department and finish
goods store for loading. Table 5.2 shows these departments with their occupying space.
34
As Figure 5.2 demonstrates in EMIC I the cut sheets and coils from service center store collect as
initial raw material and place in store1. These sheets and coils sent to cutting department in order
to be cut in required size and shape according to the customer order. After cutting operation, new
sheets sent to the pressing and then assembly department. Finally, finished products from
assembly go to final store for packaging.

5.3 Efficiency of Current Layouts
In order to measure efficiency of current layouts, the following modified equation of 3.2
explained in chapter 3 was used.

37
Based on above equation efficacies of Service Center and EMIC I are 47.6% and 55.9.
5.4 Personnel Requirements
To determine to what extent the personnel requirements at both branches of EMIC are met, a
survey was used and filled by the responsible engineer in EMIC shown in Appendix III.
According to analysis and data provided from survey following problems were identified:
There isn’t enough parking for employees.
Employees don’t have any lockers or cabinet where they can put their clothes or any
personal staff, which make them uncomfortable while the working time.
Only few restrooms available for employees and it’s located far away from working
environment.
There is only one small kitchen which is far from production area, no vending machines
offered along the factory and no specific cafeterias are there, so they have to go out the
company to get their meal.
5.5 Material Handling
The company is using several types of material handling equipment to facilitate the work and
make it easier, efficient and comfortable for the worker. The material handling equipment used
in EMIC are listed in Table 5.3.
5.6 Health and Safety
Service Center of EMIC Company suffers from two main problems that may affect the health of
employees which are noise and air contaminate. The following sections explain in more detail
these two problems.
5.6.1 Noise
Noise at work can cause many problems and affects employees’ health. It’s not necessary for the
noise to be extremely loud to cause harms in the workplace. People often experience temporary
deafness after leaving a noisy place but this will recover after a few hours. In our trip through
38
different departments of the EMIC Company we faced such problem. The people who work in
such place daily and being exposed by the loud noise are under risk. Exposure to noise may pose
a variety of health and safety risks to workers such as temporary hearing loss and permanent
hearing loss.
Temporary hearing loss: suspect hearing loss if a person complains that he/she cannot
hear something when you can. This type of hearing loss will occur when a worker spends
short time in a noisy workplace. In such case a worker might feel that he/she cannot hear
properly and there is a ringing sound inside his/her ear. In this condition the feeling of
deafness will recover after few hours. However, the longer the worker exposed to the
noise, the longer it takes for his/her hearing to return to the normal situation. That may
cause social problems because the worker may find it difficult to hear what other people
are saying.
Permanent hearing loss: long-term exposure to the noise or short exposure to a very
loud noise will cause permanent hearing loss. This type of damage can never be repaired.
In this situation if the worker notices that the normal talking or other sounds are
becoming unclear and he/she starts reading lips as people talk, so he/she is under the risk
of losing his/her hearing permanently.

5.6.1.1 Safe noise level
A safe level of noise depends on two criteria, the standard level of the noise and how long a
worker exposed to the noise. After measuring the noise in the workplace the results should be
compared with standard level of noise.
Standard level of the noise: the standard and safe level of noise allowed by most
countries is generally 85-90 dBs (Freivalds, and Niebel, 2009).
How long a worker exposed to the noise: exposure to high noise level is allowed for
periods of less than eight hours. Workers should not be exposed to noise levels above 95
dB for more than four hours per day, otherwise if he/she working more than this period
it’s necessary for them to use protection tools (Freivalds, and Niebel, 2009). The Table
5.4 gives recommended levels of noise exposure for the hours expose.
5.6.1.2 Measuring noise
In order to measure the noise inside EMIC sound meter was used. Using sound meter is an
effective and accurate way to measure the noise in certain workplace. For using this device we
have to hold the meter at arm’s length to avoid sound reflection from our body and the blocking
of sound from particular directions. For taking the reading from sound meter we have to stand
near the equipment, but not too close to the machine because the reading will vary significantly
with small change in the position of the meter.
Noise is measured in different places of the factory in distances of one meter using sound meter.
Noise graphs as shown in Figure 5.3-5.5.6 are used to identify the most risky and noisy places of
the

According to above charts there are many unsafe areas inside the company which has been
shown with red color, so the environment inside the company is not safe for workers because the
sound level is too high. However, the noisiest places are located in food section and cutting
department.
5.6.2 Air Contaminate
There is bad, undesirable and harmful smell on EMIC Company especially in the Coating
department due to the painting process. This is because they use thinner to paint without having
any ventilation system in order to reduce it, even so the workers don’t wear masks to protect
themselves from the bad smell. However the Paint thinners emit fumes, which can cause nausea,
headache or breathing trouble. Moreover the toxins in the paint thinner can absorbed into the
body, so it will causes skin irritation or skin inflammation. In the long term inhale the thinner for
long time will causes Kidney problems, Cancer, Muscle weakness, Lack of coordination and
Deaths from heart failure or asphyxiation (Freivalds, and Niebel, 2009).

CHAPTER 6: DEVELOPMENT LAYOUT
In order to develop the layout alternatives and come up with new, better and more convenient
plan options, both SLP procedures and CORELAP were used. This chapter discusses in detail
process of applying SLP and CORELAP techniques, generating layout alternatives, evaluation of
layouts and selecting the best plan.
6.1 Developing Blocks Using SLP
The major inputs to develop a layout by using SLP methods are relationship chart and space
required for each department. In order to construct the relationship chart, it was essential to
determine and understand the flows between departments of new plan. Figure 6.1 demonstrates
the flows between different divisions of Company.
New EMIC Company consist of coil storage, coil cutting department, printing and coating
department, coating and ink storage, store1, food section, store 2, prepress(design), sheet cutting
section, pressing department, assembly department, store 3 and store 4.
As Figure 6.1 indicates the flow in new layout starts from coil storage area by receiving coils
from supplier1 and these coils go to coil cutting department to be cut in smaller sheets and coils.
After the cutting operations, coils and sheets go to two directions, printing and coating
department and store1. Coils and sheets from printing and coating section move to store 2 where
large quantities of coats stored and these coats will be sent to food section when it’s needed.
Moreover, coils and sheets from store1 move to sheet cutting department to be cut in required
sizes and shapes according to the customer order. After cutting process, sheets go to pressing and
then assembly department. For final products to be assembled in addition to pressed sheets, raw
materials from supplier 2 such as nope, sealing compound and etc. are needed, so pressed sheets
from pressing department and raw materials from store 3 are met in assembly department in
order to be assembled. Next, assembled products go to store 4 to be packed and finally all goods
finished from food section and store4 will be delivered to the end customer.
According to the flows between departments relationship chart is constructed which displays the
closeness relationship among departments as Figure 6.2 demonstrates.
43

Figure 6.2 Relationship Chart for New Layout of EMIC
After determining flows between different departments and constructing the relationship chart,
space required for each department was determined considering all expansions in order to meet
45
the facilities requirements and demand in future. Table 6.1 lists down all departments with their
occupying area.

According to SLP procedure, after determining required space for each department block layout
was generated and shown in Figure 6.3.
Figure 6.3 Block Layout Using SLP for EMIC
6.2 Developing Blocks Using CORELAP
To build up the new EMIC layout block using CORELAP, some input data were required such
as number of departments, department’s areas, closeness rating, weighting values and
relationship matrix already explained in previous sections.
Using this software one block layout was generated which is shown in Figure 6.4 and other two
block layouts shown in Figure 6.5 and 6.6 respectively are modified version of CORELAP.
6.3 Selecting the Best Layout Alternative
In order to select best layout alternative, efficiency was computed using the modified equation
5.1 explained in chapter5. Table 6.2 summarizes efficiency results of all block layouts. The best
layout is the one with highest efficiency.
47
Table 6.2 Layout Alternatives Efficiency

2 The block layout of alternative (1) 80.28 %
3 The block layout of alternative (2) 87.32 %
4 The block layout of alternative (3) 76.05%
48
Figure 6.4 Block Layout Using CORELAP Figure 6.5 Modified Block Layout Using CORELAP
Figure 6.6 Modified Block Layout Using CORELAP
Based on Table 6.2 the block layout 3 with the 87.32% efficiency was selected, but efficiency is
only one important criterion in choosing the best layout. Another issue that must be consider in
selecting the best layout is plot plan which will be explained in detail in following section.
6.3.1 Plot Plan of New Layout
A plot plan is a drawing of the facility, the total site and the features on the property that supports
the facility (Tompkins et al., 2010). A plot plan for EMIC is provided in Figure 6.7.
49
Based on plot plan we recommend block layout 4, because loading and unloading areas are
located on the side which will promote interfering of tracks with other cars and also facilitate
storing and shipping process. Moreover, offices are located in front side which is close to main
entrance and at the same time easily accessible by customers who come from outside. The final
selected layout with details shown in Appendix IV.
6.4 Personnel Requirements
In order to make employees pleasant, happy and more productive, since they spent one third of
their time within facility, we recommend the Company provide basic personnel requirements for
its employees as listed down:
Providing enough parking space for employees
Providing enough lockers and cabinet where employees can put their clothes or any
personal staff.
Locating centralized and enough restrooms which are easily accessible by personnel.
Providing more than one kitchen, vending machines in different locations of Company.
Providing food court which is sufficient to serve all employees working in EMIC.
However, it is out of scope of this project to deal with these issues, so it might be considered in
future work.
6.5 Material Handling
Due to expansion of areas in the new layout, it’s important to increase number of material
handling equipment. The company is going to order two new equipment forklift and bridge
crane.
For these equipment we recommend to buy the fuels that are friendly to environment which use
natural gas, bio-diesel and bio-ethanol.
Natural gas is the most universal and available fuel capable to replace petroleum products.
Moreover, it also features a range of advantages in comparison with oil and its derivatives, the
main of which is high environmental friendliness.
50
Bio-diesel is one such alternate fuel source that is extracted from plants. Also known as E 85,
bio-diesel is partly renewable. Its contents of 15% gasoline and 85% ethanol mean that it is at
least better than using pure gasoline (Sule, 1994).
Ethanol is significantly less polluting than petrol because it doesn’t produce sulphur dioxide or
lead emissions. Any carbon dioxide it produces can be offset by growing more sugar plants. Cars
in the UK can currently run on about 10 per cent of ethanol in petrol, but the corrosive effect of
ethanol means increasing levels above this can damage the engine if the necessary changes have
not been made. The Company can choose any one of them depending on their preference and
budget (Sule, 1994)
Nevertheless, it is out of scope of this project to deal with these issues, so it might be considered
in future work.
6.6 Health and Safety
As its stated earlier, EMIC company has two problems regarding the health and safety which are
noise and air contaminant.
6.6.1 Noise
Noise problem can be controlled by attacking the noise at the source, through the use of barriers
or using ear protection tools.
Noise at the source: one of the causes of the noise is vibration and can be reduced by
decreasing either the amount of vibration or the surface area of the vibrating parts. There are
several ways to reduce vibration such as: proper design, maintenance, lubrication and
alignment of equipment. Isolating vibrating parts from other machine parts or structures by
use of resilient materials such as rubber or elastomers reduces the number, and hence the
surface area, of vibrating sources (Asfahl, 1995).
Use of barriers: if it is not possible to control the noise at the source, then it may be
necessary to enclose the machine, place sound-reducing barriers between the source and the
worker, or increase the distance between the worker and the source (Asfahl, 1995).
51
Use of ear protection tools: one of the cheapest tools to control the noise is to make
workers wear ear protection tools earplugs, earmuffs and ear protectors.
Earplugs: are worn inside the ear and come in a variety of materials, including rubber,
plastic, or any material that will fit tightly in the ear. They are the least desirable type of
hearing protection because they do not provide very effective protection against noise and
they can cause ear infection if pieces of the plug are left in the ear or if a dirty plug is used.
Cotton wool should not be used as ear protection.
Earmuffs: are more protective than earplugs if they are used correctly. They are worn over
the whole ear and protect the ear from noise. Earmuffs are less efficient if they do not fit
tightly or if glasses are worn with them.
Ear protectors: for the high amount of noise in some departments like cutting or food
section, wearing an ear protector is recommended. Hearing protectors reduce the noise
exposure level and the risk of hearing loss (Asfahl, 1995).
6.6.2 Air Contaminant
Because of the bad smell and its effects on the work environment, finding an eco-friendly and
natural components is a better way. Types of components can be citrus oil solvents as opposite
to petroleum products. Use a low VOC or no VOC (volatile organic compounds) water-based
paint, latex paint or lacquer. Another option is to use natural paints, which are composed of
natural materials such as milk protein, minerals, wax, chalk, talc, and others. Some brand name
examples are Real Milk Paint, Klean Stripe Paint Thinner, Bio-Solve, Acetone replacement, and
next paint thinners, solvents, and cleaners.
Citrus oil thinners, such as Bio Shield Citrus thinner, are free of petroleum distillates and yet can
thin oil-based paints and clean up brushes afterwards. Interestingly, turpentine that is derived
from pine tree resin is recommended as a green alternative as it is made of organic compounds,
but bear in mind that turpentine is both toxic and highly flammable.
But if the company doesn’t satisfied by using the green alternative to paint thinners because of
quality issues, they can install a ventilation system (Asfahl, 1995).
52
Ventilating is the process of changing or replacing air in any space to provide high indoor air
quality. So, providing such a system in the company is a better solution than depending only on
fans. There are three basic ventilation strategies natural ventilation, spot ventilation, and whole-
house ventilation. Brief clarification of each type will explained:
Natural ventilation: is the uncontrolled air movement in and out of the cracks and small
holes in a home. In the past, this air leakage usually diluted air pollutants enough to
maintain adequate indoor air quality. Natural ventilation is unpredictable and
uncontrollable you can't rely on it to ventilate a house uniformly. Natural ventilation
depends on a home's air tightness, outdoor temperatures, wind, and other factors. During
mild weather, some homes may lack sufficient natural ventilation for pollutant removal.
During windy or extreme weather, a home that hasn’t been air sealed properly will be
drafty, uncomfortable, and expensive to heat and cool (Wikipedia, NA).
Spot ventilation: can improve the effectiveness of natural and whole-house ventilation
by removing indoor air pollution and/or moisture at its source. Spot ventilation includes
the use of localized exhaust fans, such as those used above kitchen ranges and in
bathrooms (Wikipedia, NA).
To determine the best alternative for controlling the best ventilation system is out of this
project scope.

CHAPTER 7: CONCLUSION AND RECOMMENDATIONS
7.1 Summary
Emirates Metallic Industries Company (EMIC) is a manufacturer company which has two
branches in two different locations, identified that there is a need to design an efficient layout in
a new location with a new area to provide a significant opportunity for improving productivity
and other benefits.
This report summaries the work done on reviewing the current layouts in terms of efficiency,
personnel requirement, health and safety, and then developing alternatives layouts that minimize
cost, increase efficiency and improve work environment.
Using the SLP procedure and CORELAP, four alternatives were generated. The efficiency of the
alternatives ranged from 76% to 87% compared with the current layouts which have efficiencies
between 47% and 56%. A recommending for selecting the best alternative was given, and
suggesting for utilizing existing space most effectively and providing for employee convenience,
safe, and comfort workplace.
7.2 Project Impacts
Implementation of the recommended alternative can lead to tremendous effect in increasing the
overall performance of the company Emic, since it will increase the efficiency of adjacency
score, the traveling distance between the departments will be reduced to lead to a reduction in
material handling which has a positive friendly impact on the environment. Also, improved
personal requirements and improving health and safety will be reflected in the satisfaction of
employees to increase productivity which will lead to high profitability as Figure 7.1 illustrates.
7.3 Recommendations for future
In order to get best results of the recommended layout for EMIC Company in the future, this set
of recommendations is preferred to apply or take in consideration:
54
Figure 7.1 Project Impacts
Improve the personnel requirement in EMIC that has been suggested such as; increase
the number of restrooms , it should be a sufficient parking's, lockers should be provided
along the facility for the workers, food service locations must be assigned in the factory.
Improve the material handling by variety suggestion like expanding the number of
material handling equipment that will facilitate the transportation in an effective way and
minimizing the risk of using of some material like the fuel that can cause negative
impacts on the environment by using replacing them by an environmentally fuel.
Solve the safety problems that founded in EMIC by controlling the noise in their
departments, finding an eco-friendly and natural components to solve the bad smell in
some of their departments.
Improve the ventilation system by providing high indoor air quality by applying the
ventilation strategies—natural ventilation, spot ventilation, and whole-house ventilation.
