Executive Summary “Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young”. Henry Ford There are different ways of learning. But the first-hand knowledge can be gained by e xperiencing practical and natural situations. To gain practical experience is the utmost purpose of internship which we supposed to do for at least six weeks. Pakistan Tobacco Company (PTC) is a part of British American Tobacco (BAT) group a well-reputed multinational organization. Based in London U.K. it is a market leader in more than 50 countries with the strength of 90,000 employees selling more than 320 brands in more than 180 markets worldwide. PTC uses state of art technology in every department and it has a good corporate environment. It is a great honor and prestige for me to work for such a good company. As an Internee I have learnt a lot here and it has utilized my energy to fullest. The environment of the company was friendly and supportive for learning. I spend 6 weeks of my internship at Jhelum factory. I was assigned Secondary Manufacturing Department (SMD).The department responsible for making cigarettes and packing them. I spent most of my time on production floor. I learnt about the products of PTC. How they are made and packed. I learnt about the production lines (Making & Packing machines). I visited each and every section of the factory. In the first week we were given introduction to all the departments of i.e. Security, GLT, PMD, SMD, Quality, SCD, and HRD. The rest of all weeks I worked at SMD. All the employees that I met with during these six weeks were very co-operative. In the first part of the internship report the general information of the company has been presented. Information is gathered through different sources. The second part of the report focuses on the tasks and project assigned to me.

Introduction British American Tobacco British American Tobacco Company is the Parent company of Pakistan Tobacco Company. The company was formed in 1902, when the United Kingdom's Imperial Tobacco Company and the American Tobacco Company of the USA agreed to form a joint venture, the BritishAmerican Tobacco Company Ltd. The parent companies agreed not to trade in each other's domestic territory and to assign trademarks, export businesses and overseas subsidiaries to the joint venture. James Buchanan Duke became its chairman and the British American Tobacco business began life in countries as diverse as Canada, China, Germany, South Africa, New Zealand and Australia, but not in the United Kingdom or USA. The group was a major financial services company with the acquisitions of Eagle Star (1984), Allied Dunbar (1985) and the Farmers Group, Inc. (1988). Around 1996 British American Tobacco merged their financial operations into a single operating unit, British American Financial Services (BAFS). This division was merged with Zurich Insurance Company in 1998 to form the Zurich Financial Services Group. B.A.T still owns the minority interest in Zurich.
Pakistan Tobacco Company A Brief History From being the first multinational to set up its business in Pakistan in 1947 and beginning operations out of a warehouse near Karachi Port, PTC has come a long way. From being just a single factory operation to a company which is now involved in every aspect of cigarette production, from crop to consumer, PTC has evolved and grown with Pakistan. However, what is significant about these 64 years is the effort that Pakistan Tobacco Company has demonstrated in the development of the country. By being instrumental in the campaign for modern agricultural and industrial practices, PTC has helped in the development and progress of the agricultural and industrial sector in the country.

Internship Report
PTC has been supporting and contributing to various causes of national interest. Educating growers in the latest techniques and technology in agriculture, afforestation and free health care in designated areas are but a few examples. Throughout these 64 years, PTC’s continuous i nvestment in people, brands, technology,
innovation and the communities in which PTC operate has borne fruit in many ways. PTC is deemed as a partner of choice by many, its Environmental, Health and Safety standards are a source of inspiration for local companies, our industrial relations practices have led and influenced local practices, and as a result of all these, our managers are highly valued and sought after people in the Pakistani corporate world based on the training and exposure PTC gives them from very early on in their careers. The Company acquired 5S certification in 2007 and it is the only company with this status. PTC is the recipient of the annual Environment Excellence Award by the National Forum for Environment & Health. Adding to this list, company bagged ISO14001 certification related to Environment and OSHAS 18001certification concerned with Health and Safety. Suffice it to say that the history of the Pakistan Tobacco Company is closely linked with the development and history of the areas in which PTC operate. Be it corporate practices, social investments, advancements in agricultural techniques, or establishing new ways of marketing and distribution, PTC has always been instrumental in establishing the benchmarks against which others are measured.
PTC Factories There are currently two PTC factories operational in Pakistan along with a Head Office in Islamabad. One is situated in Jhelum and the other in Akora Khatak. Both factories have similar production capacities. Both the factories produce around 22 billion sticks per year. In 1957, Jhelum plant started its operation with a single shift. Slowly more shifts were added to enhance production. Akora Khatak plant is primarily utilized to manufacture products that can cater for the lower income groups. In addition to this, this plant also houses a Green Leaf Thrashing Plant which serves to satisfy the need of local tobacco in cigarette production in both the plants. In terms of technology, Jhelum plant is more advanced than Akora Khatak plant with better and faster machines. Both factories work 24 hours a day, 7 days a week, with some time reserved for, cleaning the machines, coping with breakdowns and scheduled routine maintenance of machines.

Internship Report
Brands of PTC PTC has always considered it-selves a consumer-focused company. They aim to offer a product that excels in all aspects and exceeds the expectations of the consumer. PTC carries out market research in order to look at the trends and associations that have been developed by its consumers. It is through that research, PTC is able to devise its strategy of which brand production needs to increase and which needs to slacken. Different brands have been produced to cater f or the relatively diverse economic background of the people. From the very low-priced Embassy to expensive brands such as Dunhill form the varied nature of PTC Brands. There are two brand categories.
Premium Brands
Dunhill Benson & Hedges John Player Gold Leaf
Low Priced, High Volume Brands
Capstan by Pall Mall Gold Flake Embassy Wills Int.
Amongst these, the highest manufacturing products are John Player’s Gold Leaf and Capstan by
Pall Mall which are manufactured regularly while the more premium brands such as Dunhill and Benson & Hedges are manufactured with a relatively small volume according to the demand of the consumers.
DUNHILL Dunhill, a premium global brand, celebrated its centenary in 2007 and 2008 was an exceptional year for Dunhill in Pakistan as the brand witnessed exponential growth; fueled by its re-launch in July. Going forward, Dunhill is poised to strengthen its foothold in the DUNHILL. 10 | P a g e
Internship Report
Currently there are three brands of Dunhill in production: Dunhill Full Flavor, Dunhill Lights and Dunhill Swiss Blend. Dunhill Lights and Dunhill Swiss are being produced to fulfill the demands of health conscious smokers.
BENSON & HEDGES In 1873, Richard Benson & William Hedges started a partnership in London. Benson & Hedges was launched in Pakistan in March 2003 and has since been able to build strong brand loyalty among its consumers showing excellent year on year growth. Two brands of B&H are being produced in the facility namely B&H FF and B&H Lights.
John Player Gold Leaf The story of John Player Gold Leaf has to start from the story of its founder, John Player. An enterprising businessman, John Player, started a small tobacco selling business in 1877 and turned it into a thriving cigarette company, John Player and Sons. John Player Gold Leaf has become an institution in itself, becoming one of the most recognizable cigarette brands in the country. John Player Gold Leaf has recently been declared the largest Urban Brand in Pakistan, beating out products across the F.M.C.G. spectrum.
CAPSTAN BY PALL MALL Capstan has a rich heritage, originating in Britain in the 19th century; the brand was created under the auspices of W.D. & H.O. WILLS at Bristol and London. The recent introduction of Capstan Rich has been a new boost to the production of the factory. The new brand has been introduced after the public demand of light brands.
EMBASSY Embassy, is a leading volume brand in Pakistan, and is most popular in Punjab where it enjoys a leading position. Having built its heritage over a number of years, Embassy thrives on its brand
11 | P a g e

loyalty and locally tailored taste characteristics. And for the company, it’s categorized under Low
Price, High Volume Blend.
GOLD FLAKE Gold Flake, like many of PTC’s brands, also boasts its origins at W.D. & H.O. WILLS where it was a premium brand around the end of the 19th century. Launched in 1982, in 'soft cup' packing, the brand took off when it was repositioned in the Value for Money (VFM) segment and later a 'hinge lid' variant was introduced in 2000. Gold Flake has grown tremendously as a brand since 2004, making it the largest volume brand in Pakistan, and the second largest brand in British American Tobacco's Asia Pacific region. The key to Gold Flake’s success has been its novel engagement schemes which have fueled growth over the years. Through consumer relevant initiatives, Gold Flake has established itself as a fresh and modern offering in the VFM segment and is all set to consolidate its position as the major volume driver for Pakistan Tobacco Company.
Departments There are several departments in the Jhelum Factory which are working in tandem to make sure that the factory remains operational. All the functions are synchronized so as to create no gap in the communication between departments. This factory resembles a ‘well -oiled machine’ that keeps running and consistently reaching its goals. All the departments play a vital role in the overall efficient working of the factory. The list of departments is as follows: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

Internship Report
Secondary Manufacturing Department PTC-Jhelum Factory has two major departments that are mostly related to end product- Primary Manufacturing Department (PMD) and Secondary Manufacturing Department (SMD). SMD (Secondary Manufacturing Department) is responsible for making the complete cigarette and its packing. The SMD floor has nine MAKERS and nine PACKERS with each line associated with one maker and one packer. There are two maker machines-LOGA and PROTOS. There is 1 LOGA and 8 Protos present on the floor. There are different models available in the packer machines too that are GD-X1, X2 and X3. SMD has ODMS area and CASE-PACKER area on either side. ODMS (One Day Material Store) provides the daily required material such as cigarette paper, tipping paper, packing glue etc. Case packer area receives completed outers from packers and fills 50 outers per carton which are transported to warehouses to be shipped out. The SMD floor also has a quality office maintaining the quality of cigarettes and the packs being produced. SMD works in four shifts with three shifts at work one single day. It is a 24-hour working department. Each shift is headed by a production manager who is supported by a team leader. Then there are the machine operators working tirelessly to produce the required number of cigarettes. They are helped by various casual workers who look into the menial jobs on the floor.

Filter Maker Filter maker makes a Filter Rod for the cigarettes. One filter maker machines produce 3000 filter rods per minute. Each rod contributes to six sticks of cigarettes (four sticks in case of Gold Leaf Special, B&H, and DUNHILL).
Filter Shooter Filter shooter is the machine which deliver filter to the cigarette making machines. These machines are called Filtromat. These machines receives filter through filter trays which are filled by Filter Maker and shoot the filter through steel pipes.
Maker The maker is provided with the tobacco from the feeder areas through pneumatic fans. The maker is responsible for the making of cigarette sticks which (on average) produces 8000 and some machines produces 10000 cigarettes per minute per machine. Maker machines receives tobacco from feeder and filter from filter shoots and makes different types of Cigarettes.
Packer The sticks produced by the maker are divided into segments of 20 and moved towards the packer. Each segment is then passed through various sensors to ensure its quality of firmness and consistency. Then each packet is filled with the segments of 20 cigarettes each and formed into a cigarette box which is later laminated. 10 boxes are then stacked together and laminated to form a complete outer and then further pushed to the CPC to be available for distribution. The packer is on the wage of producing 500 cigarette boxes per minute.
Case Packer Case packing is the shortest procedure in the whole manufacturing. Outer from the outer belt and outer conveyor enter the case packing machine. It carries lift hopper with 5 sensors up and 5 sensors down. The sensors make sure that a bundle of 25 outers enter the CBCs at a time. Two bundle of 25 are sent to the CBC. Ceiling of solution tape on both side is applied and finally a CBC carrying 50 outers enter the finished goods warehouse.

Protos Protos 90ER
Protos 100
Protos 80ER
Protos 80
There are total nine maker machines working on the floor. These machines are divided into two types LOGA and PROTOS. The Protos are the latest machines having large efficiency and performance than the Loga. There are eight Protos and one Loga on the floor. The Protos have different types depending upon the performance and working parts. Loga has a rated maximum speed of 8,500 CPM (cigarettes per minute) and Protos varies between 8000-1000 CPM depending on the model.
19 | P a g e
Internship Report
PROTOS is used more often in making the premium brands such as Benson & Hedges, Gold Leaf and Dunhill. Whereas, LOGA has more use in the production of high volume brands like Capstan and Gold Flake. Protos 90ER have high speed machines having speed 10,000 cigarettes per minute.
LOGA Machines LOGA machines are relatively low performance having speed ranging from 5000cpm to 8500CPM. There is only one loga on the floor having speed 8500 CPM. Unlike the PROTOS these machines cannot accommodate any LASER units. These machines are engaged in making high volume brands like CbPM and GF.
PROTOS Machines PROTOS has lower rejection rates when compared to LOGA and thus has a much better efficiency. There are eight Protos one the floor. Four Protos 90ER having speeds of 10,000 CPM. Two Protos 100 having speeds of 10,000 CPM. One Protos 80ER having speed of 8,000 CPM and one Protos 80 having speed of 8,000.

Title: RCO Understanding Objectives: The project has the following Objectives. •
Study the Brand change Overs & Format change overs.
•
Change Overs Downtime Analysis.
•
Manually observing all the activities during change over.
•
RCO Deployment for reducing changeover downtime.
Abstract: The project assigned to me was RCO understanding for reducing change overs downtime. 14.4 million Sticks could be produced in a day if a line remains operational 24 hours a day. If there is a stop due to any reason for a minute 10,000 sticks are not produced so the OEE (Overall Equipment Efficiency) is affected. Changeovers have significantly large downtimes so the production targets and the OEE is significantly affected by them. The time required to remove old tooling, equipment from one production and install the same for the next run is known as the setup time. Setup time includes anytime that production is stopped. It is similar to downtime. Setup operations have traditionally demanded a great deal of time, and manufacturing companies have long suffered from the extreme inefficiency this causes. Reducing setup/down time lowers cost/unit, Increases capacity and efforts lead to standardized process, reducing variation in process results. The four basic steps in a setup are: 1. 2. 3. 4.
Preparation, after installation adjustments, checking materials and tools. Removing and installing actual tools. Measurements, Settings and Calibrations. Trial runs and adjustments.
So these process increases machine downtime and the production targets are affected. The purpose of RCO is to reduce machine change overs downtime.
24 | P a g e
Internship Report
Downtime Analysis I have done analysis of Data of change overs downtime starting from 1 st January, 2016 till July end. Analyzed the downtime of different changeovers, shift wise and brand wise. This analysis can be used to select target are or pilot area for RCO. The analysis of both makers and packers downtime was done and Changeovers to all the brands were covered.
Downtime Analysis Deductions:
Late shift has mostly less downtime than early & night shifts.
The difference between minimum and maximum time is very high.
If the minimum time of 15 minutes have been achieved then why the average downtime is two hours???

Change over from CBPM to B&H.
RCO Understanding It stands for Rapid Change Over. A system used for reducing change overs downtime. Each element of the changeover is analyzed to see if it can be eliminated, simplified, moved or streamlined. The objective of RCO is to reduce change overs downtime significantly with proper planning, eliminating delays, team work and advanced equipment. It has the following advantages
Reduced downtime. (Increased OEE).
Increased capacity.
Greater flexibility.
Reduced stock. Improved responsiveness to customer demand.
27 | P a g e
Internship Report
Example of RCO Consider the example of changing a tire. •
•
It takes 15-20 minutes for a person to change a single tire. NASCAR pit crew takes less than 15 seconds for changing four tires.
Techniques used by NASCAR pit crews. •
•
Performing as many steps as possible before the pit stop begins. Using a coordinated team to perform multiple steps in parallel.
So the journey from a 15 minutes tire changeover to a 15 second time changeover can be considered a RCO journey.

Steps of RCO Process Mapping Separating External Organizing External Converting Internal Streamlining Internal
Continuous Improvements
Step 1: Identify Pilot Area: From shift wise downtime analysis on makers consider the changeover from CBPM to PG in early shift. It can be seen that: The target area for the pilot RCO program is selected. The Ideal line will have the following characteristics.
Duration: The change Over should be long e nough to have significant room for improvement.
Variation: There is a large variation in changeover times.
Opportunities: There are multiple opportunities to perform task each week.
Familiarity: Employees familiar with the equipment are engaged and motivated.
From shift wise downtime analysis on makers consider the changeover from CBPM to PG in early shift. It can be seen that:
29 | P a g e
Internship Report
Step 2: Identify Elements Analyzing all the steps of the changeover. (Process Mapping). Video: Visually record the changeover Manual Observation: Manually record every step by observing and question. Some important characteristics of this step: Elements: Note every single element of changeover. Man and Machine: Capture both man and machine. The human elements are usually easily to optimize. Observe: Only observe let the changeover take it normal course. The deliverable from this step should be a complete list of changeover elements each with a description and time cost.
Step 3: Separate External Elements In this step the elements that can be performed while the equipment is running are identified. Such elements of changeover are called external elements. It is not surprising that changeovers time to be cut nearly half with this step alone. Examples:
Retrieval: Retrieval of parts, tools and machines.
Inspection: Inspection of parts, tools and materials.
Cleaning: Cleaning tasks that can be performed while machine is running.
Quality: Quality checks for the last production run.
The deliverable from this step should be an updated list of changeover elements, split into three parts External elements (Before changeover), internal elements (During changeover) and external elements (After changeover).
Step 4: Converting Internal The changeover process is carefully examined, with the goal of converting as many elements to external as possible. The following question should be asked: If there was a way to make this element external, what would it be? How could we do that?? Some example techniques: 30 | P a g e
Internship Report
Advance preparation: Prepare parts in advance. Jigs: Use duplicate jigs. Modularize: Modularize equipment (e.g. replace a printer instead of adjusting print head so the printer can be configured for a new part number i n advance of the changeover.
The deliverable from this step should be an updated list of changeover elements, with fewer internal elements and additional external elements.
Step 5: Streamline remaining Elements The remaining elements are reviewed with an eye towards streamlining and simplifying so they can be completed in less time. Some example techniques: Release: Eliminate bolts (e.g. use quick release mechanisms or other types of functional clamps) Motion: Eliminate motion (reorganize the work space). Operations: Perform parallel operations.
Step 6: Continuous Improvements Always keep looking for further improvements and opportunities.
New Technologies.
New people-New Ideas.
New premises or changes to layout possible.

Internship Report
Step 3: Organizing External Elements: At 6:01 changeover started. Operator 1 started cleaning the machine and removing material from the GD part of the machine and cleaning the surroundings of the machine. The contractual worker started removing wastes from the surroundings of machine. There was a jam in C-600 part of the machine so it took a long time to remove p revious material. Moreover the operators were also waiting for blanks to arrive but blanks were late. Second operator changed the code and date. When the jam was cleared and machine was operational at 6:57 a quality officer came and asked to stop the machine and checked the surroundings of machine he founded some previous waste beneath the machine so asked the workers to remove that. Machine started operating again at 7:09. Suggestions: The blanks could reach before the process stop. The cleaning of surrounding could be done before stopping. The quality check could be done either after running the machine. To stop the machine was not a good idea. There was a jam and operators were not technical so it took time to clear the jam.
Step 4: Convert Internal Elements to External Removing wastes from the surroundings of machine or cleaning of machine. Bringing blanks from the ODMS before process stops etc.
Step 5: Streamline remaining elements: The remaining operations can be simplified like instead of changing code and date use two printers and replace the printer.
Step 5: Continuous Improvement: It’s not mandatory that the downtime will reduce to its lower after one try so keep analyzing the
process and try to bring new ideas and new changes to improve the process.

Conclusion The Changeovers downtime can be significantly reduced by deploying RCO. More than 40% setup time can be reduced by eliminating delays, proper planning, and Segregating external and internal activities. Since the RCO was deployed first time in Jhelum factory on 15th Aug, 2016 to 17th Aug, 2016 so it will take time to completely implement this and get significant result from this system but on the basis of this foundation this system can be improved to reduce downtime. My time at PTC was well spent, and I had a great learning experience. I had the opportunity to work in a corporate environment. I saw how the work force is organized, how different shifts are arranged to gain maximum output and how workers are kept satisfied. It exposed the way of working of multi-national companies and got me familiar with the policies and strategies that most of the multi-national companies practice like Lean Production, 5S policies, Integrated Work System (IWS) ,Total Quality Management and Total Productive Maintenance. I learned how and why records are maintained. All of my projects required me to gather data about previous productions and material issuance. Without efficient record keeping a production floor can never keep track of its downtime, stops, wastes and other production problems. In short, I learned about the application of engineers in a management role which I do not think that I could have experienced in a university or another company.
