Tefal Pot
1. Introduction Our Product was Tefal Cooking Pot The Product is The Base™ 2 Pot Set provides essential non stick performance
for people who love to cook but hate to clean up. It’s the perfect size and weight for use on any backcountry excursion. Its compact design is pack friendly, and there’s room inside for adding mugs and plates to customize your kitchen without taking up more space
Material Used: Stainless Steel Alloy with PTC Non-Stick Coating that also can resist thermal shocks
So we can control the manufacturing process of the pot with maximum efficiency we needed to achieve near optimum results for 2 main parameters in our project:

5.2. Operators
5.2.1. Approximate number of needed operators in the production area 15 operators
5.2.2. Number of operators for each machine type This approach for selection the proper number of workers in the production line (no services is included) based on the aggregate planning of the production line
Note: The production line has 3 Engineers to Maintain, monitor & control the production line
The Handle Installation Workstation consist from two sub branches handle installation
1) Handle installation for Pot body 2) Handle Installation for Cover
The Distribution of workers on the main production line is as following:

6. Facility Areas design
6.1. Production Area
6.1.1. List of departments in the production area 1. Manufacturing (Body making + Handle Assembly + Inspection + Packaging)
2. Design Office 3. Management
4. Cafeteria 5. Health Office
6. Rest rooms / Locker Room

6.1.2. Name of layout for the production area Product Layout
And that for the following reasons:
Product layouts are found in flow shops (repetitive assembly and process or continuous flow industries).
Flow shops produce high-volume, highly standardized products that require highly standardized, repetitive processes. In a product layout, resources are arranged sequentially, based on the routing of the products. In theory, this sequential layout allows the entire process to be laid out in a straight line, which at times may be totally dedicated to the production of only one product or product version. The flow of the line can then be subdivided so that labour and equipment are utilized smoothly throughout the operation. So that will be the most suitable layout for us.
6.1.3. Schematic drawing showing flow of material from stores to warehouse (using edraw max 7.8)
Figure 14 : Material flow
14 | P a g e
6.1.4. The production area drawing (using edraw max 7.8)
Figure 15 : Production area
15 | P a g e
6.1.5. The required production area Total machine length = 1.5+1.5+4+12+1.5 = 20.5 m Total length = 1.5+1.5+4+12+1.5+1.5 = 22 m Machine area = 22 × 1.8 = 40 m2 Cover assembly machine area = 22 × 1.5 = 33 m2 Total layout area = 13.8 × 22 = 305 m2
Required production area = 13.8 m X 22 m
6.2. Personal requirements areas
6.2.1. Parking area
6.2.1.1. Parking layout drawing
Figure 16 : Parking layout
16 | P a g e
6.2.1.2. Calculation of the required area of parking + Number of employees in the firm= 65 employees distributed as the following:
18 employees in manufacturing section
12 employees in workshop (Maintenance)
3 employees for material handling
8 employees in inventory section
7 employees for service (Cafeteria-cleaning- Security)
17 employees for management
+ As the firm is neither centralized nor served by public transportation so 1 parking place is provided for every 1.25 employees
∴ The number of spaces in firm = 50 spaces
+Types of cars:
45% of all cars driven to work are compact cars. 50% of all cars driven to work are standard cars. 5% of the spaces allocated for handicapped cars PW=SW = 12 feet
Estimated parking area:
90 feet width 200 feet depth Cross aisle width = 15 feet
Notes:
No walls and no walking edge Parking angle of 90 degrees
“Module used is module 4”
Table 7 : Parking calculations
Type of car PW=SW W Number of spaces per module
Compact 8 57’2’’ (90/8)*2= 23 Standard 8’6’’ 66’ (90/8.5)*2= 23
17 | P a g e
Required spaces for compact cars: 45% × 50 = 22 spaces Required spaces for standard cars: 50% × 50 = 25 spaces Required spaces for handicapped cars: 5% × 50 = 3 spaces Therefore parking layout includes 1 module for compact cars and 2 modules for
standard cars.
Assume handicapped cars will park in Row 1 with standard cars:
Therefore, remaining space in row (1) = 60 – (12×3) = 54 feet. Calculating number of spaces in each row:
Row (1): Number of spaces = 54/8.5 = 6 spaces Row (2, 3, 4): Number of spaces = (60-30)/8.5 = 7 spaces Row (5): Number of spaces = 60/8 = 8 spaces Row (6): Number of spaces = 90/8 = 12 spaces
NOTE:
“Row (4) will include 5 standard cars and 2 compact cars”
6.2.2. Food service area
6.2.2.1. Food service layout drawing
Figure 17 : Food service layout
18 | P a g e
6.2.2.2. Calculation of the required area of the food service As number of employees is less than 200 employees so we use a vending
machine + Cafeteria 1 hour (from 11.00 am to 12.00 am) is provided daily for meals divided into 2
sections as the following
Table 8 : Food service calculations
Begin of meal Time sat down in chair End of lunch break 11.00 11.10 11.30 11.20 11.30 11.50
So the Vending machine area and the cafeteria area is provided for 33 employees in the shift
Vending machine requires 1 ft2 per person Cafeteria requires 15 ft2 per person using 36-in square tables
6.2.3. Other areas (Locker room, rest room and health room)
6.2.3.1. Men’s rest and locker room

Area = 29.26 m2

7. Material handling
7.1. Fork lift Flexible motion Variety of load capacity ( can handle up to one ton load of material) Load is one carton which is low quantity material moved Distance moved from warehouse to production line which is long distance And according to Material Handling Equipment diagram which help us choose
optimum type of material handling equipment
Powered trucks are best solution for long distance and small quantity (carton)
We choose one ton fork truck as load handled is less than load capacity of it and decrease costs .One ton fork truck needs 9 aisle widths

Figure 22 : Fork truck 1 flow Fork truck 2 Moves from storage holding body handles, Packages and cartons to pneumatic screw driver then to oven then to packaging and go back to storage to begin a new cycle
Figure 23 : Fork truck 2 flow Fork truck 3 Moves from Cover packaging holding 1000 Cover Packaged to final packaging area to be packed with body in cartons then holding cartons from final packaging area to Warehouse and the go back to cover packaging to begin new cycle

7.2. Conveyor
Second Material handling equipment in production line
In Line production case:
Load is unity and high quantity material moved Need accumulation of loads at Packaging Linear motion between machines which is short distance Don’t need any inclination motion And according to Material Handling Equipment diagram which help us choose
optimum type of material handling equipment
Conveyors are best solution for short distance and large quantities handled
Usage (Specific): Tefal body handling from deep drawing machine to the end of the process

8. Conclusion In this report we have discussed our design approach & its implementation in terms of design, manufacturing & process, and then we discussed the major elements effecting the production of that product (Machines, Tools, Materials & work force).
After that we took a look on the facility strategic planning in respect to 3 major points
Production Line Personnel Requirement Logistics
Then we introduce a solution based on real data acquired from Zahran Co. Egypt we used the Six Sigma implementation for trying to improve productivity and lower the waste
In this report we used many tools that helped us in collecting, processing & analysis the data to get the required information that we need for the discussion of this project like:
MS Office Package CAD using Solidworks FEA using JMAG Designer Plant Simulation using Siemens Plant Simulation Layout Drawing using Edraw Max Charts Design & Drawing using Xmind
In the end we hope we could have managed to give a basic foundation of the effect of facility planning on the production quality based on our case study.
