A Comprehensive Study on Lean Manufacturing Process
Lean Manufacturing:

Lean Manufacturing – A way to eliminate waste and improve efficiency in a manufacturing environment. Lean focuses on flow, the value stream and eliminating ‘muda’, the Japanese word for waste. Lean manufacturing is the production of goods using less of everything compared to traditional mass production: less waste, human effort, manufacturing space, investment in tools, inventory, and engineering time to develop a new product. Lean is the systematic approach to identifying and eliminating waste through continuous improvement by flowing the product or service at the pull of your customer in pursuit of perfection.
 

Origin:
During II world war, the economic condition of Japan was heavily destroyed. They had limited infrastructure, inventories, machine & materials. So they decided to produce a small batch of products which would reduce inventories; it means they would need less capital to produce the same product. Lean manufacturing is a management philosophy derived mostly from the Toyota Production System(TPS) because Toyota Motor Company’s Eiji Toyoda and Taiichui Ohno are given credit for its approach and innovations, this system identified as "lean" only in the 1990s.

Areas of Lean:
   Quality- Increasing quality.
   Cost- Reducing cost.
   Productivity- Increasing productivity.
   Safety and morale- Ensuring safety.

Waste elimination:
Waste is anything that happens to a product that does not add value from the customer’s perspective. Products being stored, inspected or delayed, products waiting in queues, and defective products do not add value. There are seven major types of waste –
   Overproduction – Producing more than the customer orders or producing too early. Inventory of any kind is usually wastage. TPS pays particular attention to the waste of overproduction.
   Queues – Time is a limited resource. In the manufacturing world, time is money. Customer requirements are calculated to the second. Idle time, storage, and waiting are wastes.
   Transportation – Moving material between plants, between work centers, and handling more than once is waste.
   Inventory – Preventing unnecessary inventory is critical to the success of the Toyota Production System. The smooth, continuous flow of work through each process ensures that excess amounts of inventory are minimized unnecessary raw material, work-in process (WIP), finished goods, and excess operating supplies are wastes.
   Motion –Motion is the movement of equipment or people. Wasted motion occupies time and energy. Ideally all unnecessary movements or actions are eliminated from the work process.
   Over-processing – It refers to the works performed on product that adds no value. Over processing is as wasteful as insufficient processing. Employees must learn to identify over processing waste.
   Defective product – The waste of correction is a result of poor internal quality. Producing defective products or products requiring repairs adds the cost of extra manpower, materials, facilities and conveyance measures.
   
Advantages of Lean Manufacturing:
   Increased overall productivity.
   Reduced amount of floor space required for production.
   Reduced manufacturing lead time.
   Improved flexibility to react to changes in production flow.
   Improved quality of the product.
Disadvantages of Lean Manufacturing:
   Difficulty involved with changing processes to implement lean principals.
   Long term commitment required for permanent change.
   Very risky process in case of supply chain issues while changing over to lean.

Knitting / Knit denim
« on: September 18, 2018, 05:30:05 PM »
Introduction:

Whether elegant or artificially aged, worn with a jacket or a T-shirt, jeans go well with almost anything. They are simultaneously a lifestyle statement, worldwide cult classic and long-selling fashion garment – with no end to the success story in sight. Denim accounts about 3% of total world fabric production. The statistics tell us that a US American has eight pairs of jeans, while a European comes a close second with five to six pairs [1]. Almost two billion pairs of jeans are produced each year, claiming about 10 percent of the worldwide cotton harvest. Following that trend, the new denim product is storming in the knit market globally. Though the indigo knits have been created for a long time, a huge increase in demand for these products came from the time Jeggings trend in woven denim became popular. With the woven denim fabrics being initially used to create the super tight jeggings, the need for further comfort – while maintaining denim looks – was felt strongly and this has given chance to knit based fabrics, what we called knit denim.  The comfort ability of knit denim garments as well its stretch ability makes the fabric mold and move easily with body movement thereby creating huge demand to the customers. The global leader in textile and clothing, China is the first country that has created and implemented idea of creating knit denim look in knit fabrics with french/or terry structure (cloth that features loops and soft piles of yarn). Bangladesh as one of the cheapest production centers for apparel around the world needs to focus on fashionable elements on denim fabric thus adding value to the product using different effect such as denim effect on knitted fabric and put a step towards value addition and sustainability.
About Denim:
Fashion trends come and go as each decade goes by, but one trend that has remained intact over so many seasons is the beloved denim. A trend that was born in Nimes, France and raised in America, denim collections have undergone tremendous changes through the passing years. Created in the 18th century for miners due to the durable nature of the fabric, denim didn’t become popular until the 1930s. The popularity of denim continued to grow during the following decades, and was transformed forever in the 1980s with debut of high fashion denim. Jordache, Calvin Klein and Sergio Valente were amongst the pioneers in creating slimmer, tight fitting designer jeans.

Textile Engineering / Exports climb on apparel boost
« on: May 12, 2018, 06:29:38 PM »
Exports grew 7.11 percent year-on-year to $2.95 billion in April riding on the higher shipment of garment items.

Although the receipt is 0.51 percent higher than the monthly target of $2.94 billion, it was the lowest in six months.

Overall, exports rose 6.41 percent year-on-year to $30.40 billion in the July-April period. The earnings narrowly missed the periodic target of $30.49 billion, according to data from the Export Promotion Bureau.

Garments exports grew 9.37 percent year-on-year to $25.30 billion in the first 10 months of the fiscal year.

Knitwear exports rose 11.43 percent to $12.54 billion and woven garments exports were up 7.42 percent to $12.76 billion.

The shipment of garments, which account for more than 80 percent of the national export, grew because of the increased sales of high-value items and the depreciation of the local currency against the US dollar, according to exporters.

“We will be able to achieve more than 10 percent garment export growth at the end of the fiscal year as the trend in the international market shows very bright prospects,” said Siddiqur Rahman, president of the Bangladesh Garment Manufacturers and Exporters Association.

“At the end of the current fiscal year, we will be able to surpass the garment export of $30 billion for the first time," he said.

He said the country's garment factories are full of orders from international retailers and brands, thanks to the massive progress in workplace safety carried out by the Accord, the Alliance and the government.

The exporters also benefitted from the depreciated exchange value of the taka.

On Wednesday, the interbank exchange rate was Tk 83.10 per US dollar, up from Tk 80.50 a year earlier, according to central bank data.

Frozen and live fish exports grew 2.32 percent to $434.97 million on the back of the higher demand in Europe.

Shipment of agricultural products such as fruits and spices was up 16.77 percent to $543.18 million.

Cement, salt and stone fetched $11.08 million, up 33.01 percent, and pharmaceuticals brought home $85.96 million, an increase of 14.84 percent.

Cotton, cotton products, and yarn exports went up by 19.01 percent to $108.22 million in the July-April period.

Jute and jute goods also fared well as the demand for the goods made in Bangladesh from the natural fibre is rising.

In July-April, jute and jute goods fetched $889.74 million, up 7.66 percent.

Home textile export rose 13.07 percent to $751.67 million, footwear 5.29 percent to $205.30 million and furniture 21.86 percent to 51.68 million.

On the other hand, exports of plastic goods fell 19.92 percent to $81.19 million in July-April.

Leather and leather goods sector, the second largest export earner after garments, fetched $916.74 million in the 10-month period, down 10.02 percent.

The shipment of leather and leather goods was hit largely by the relocation of tanneries from Hazaribagh to Savar as production was hampered.

All the 155 tanneries have been relocated, but only 25 of them have so far been able to start production in their new location, industry people said.

Chinese scientists have come up with a new membrane material which can efficiently separate salt from water and has other water purification functions.

A research program led by professor Zhang Lin with the Zhejiang University developed the membrane formed by nanoscale bubbles and tubes. The material allows water to permeate three to four times faster than traditional membrane for water purification.
Zhang likened the function of the membranes to the interior of the mammalian intestine as it absorbs water and nutrition.

Zhang expects the membranes to have a variety of applications in home water purification, industrial waste water treatment and desalination.

The research is ready for commercialization.

The study was published in Science magazine on Friday.

Business and Economics / Dhaka to see six new luxury hotels
« on: May 07, 2018, 01:37:03 PM »
Dhaka to see six new luxury hotels
Operators splashing out Tk 5,400cr
Dhaka is set to welcome half a dozen international hotel chains over the next couple of years, brought about by the growing influx of business travellers to Bangladesh.

“The economy is expanding and so is the number of guests,” said Md Jashim Uddin, vice-chairman of Bengal Group of Industries, which is constructing a 370-room hotel in the capital's Niketan area for about Tk 600 crore.

The property will be managed by Swiss hotel chain Swissôtel Hotels and Resorts. “We want to make the ultimate business hotel, which we do not have in the city yet,” he added.

Bengal is not the only local business group pouring in funds to expand the capital's luxury hotel landscape; Jamuna, Marium and Premier are entering the fray too.

New business opportunities have come up for construction of large infrastructure projects such as the Padma bridge, Rooppur nuclear power plant, metro rail and LNG terminals.

At the same time, the flow of business travellers related to the export-oriented garment industry is set to get bigger as the apparel makers chase an export target of $50 billion in 2021.

Altogether, the new hotels are expected to bring forth investment of about Tk 5,400 crore, according to industry insiders and a banker.

Marium Group is establishing a 200-room hotel in Hatirjheel area for about Tk 1,500 crore. The property will be christened the Holiday Inn Dhaka City Centre and is expected to open its doors to guests by the end of this year.

“There is a huge demand for luxury hotels. In fact, it is more than the supply in the city,” said Alam Ahmed, managing director of Holiday Inn.

Jamuna Group has struck a deal with Marriott International, the American luxury hospitality chain, to set up the 700-room JW Marriott Dhaka. The hotel will be located at Jamuna Future Park in Progoti Sarani. Premier Group is building JW Marriott's sister brand Courtyard by Marriot in the capital's Gulshan area. Unique Group, the parent company of Westin Dhaka, is establishing Sheraton Dhaka in Banani, while Lakeshore Hotels has teamed up with Thai hospitality group Dusit International to set up a business hotel in Uttara for Tk 150 crore.

Once all the under-construction properties become operational, the total supply of upscale hotel rooms in Dhaka will more than double to 3,000 from existing 1,250, according to industry operators.

The new entrants will also drive up competition, and possibly lower the room tariffs, said MA Awal, director of sales and marketing of Pan Pacific Sonargaon Dhaka.

He went on to state that the supply is growing faster than the demand. Al-Amin, director of sales and marketing of The Westin Dhaka, differs in opinion.

“The room rates in upscale hotels in Dhaka are high, which reflects the solid demand,” he added.

Shahidus Sadeque, director of marketing and business promotion of InterContinental Dhaka, which is expected to resume welcoming visitors later this year, has a similar position. The economy grew steadily in the last five-six years, but the number of international hotels has not increased to that extent, he said.

“Our market is under-supplied. We have only half a dozen of international hotel brands whereas Kolkata has more than a dozen of such hotels,” he added.

At present, five international hotel chains are serving in Dhaka: Marriott International's brands Westin and Le Meridien, Radisson, Pan Pacific and Amari.

About 3.1 million visited Bangladesh in the last six years and the average occupancy rate in the upscale hotels in Dhaka is 60-70 percent, according to Syed Mehran Hussain, manager marketing of Four Points by Sheraton, which began operations last year. “And the number is increasing day by day. With the rise of visitors, the number of star-hotels is also increasing.”

Textile Engineering / Quality product vs. low price:
« on: April 22, 2018, 11:13:51 AM »
Though order is increasing, RMG executives are facing a great problem in product pricing. Foreign Buyers want quality product with a low price. For various reasons, including energy crisis and factory remediation cost, production cost has increased by 18 percent, according to Bangladesh Garment Manufacturers and Exporters Association (BGMEA). However, the garments product price of Bangladesh has declined to 40 percent in last 15 years, according to the research of Pennsylvania University and Colorado University.
Our customers always demand good product but offer low price. If we can survive in this low price then order will increase, said NurulMahmoodTuhin, Country manager of Golden Touch Import Ltd.
“At present yarn cost is high, government added more tax and Accord Alliance pushing continuous pressure. So the Govt., BGMEA, BKMEA should take proper step in price issue as day by day production cost is increasing,” said Mahbub Hossain and MahmoodTuhin.
The price should be good enough to maintain a sustainable business, industry insiders told. They further opined that taking order at price which is not profitable has no meaning for the industry. There are allegations that some companies specially having big volume capacities are taking orders at such low price which is literally impossible to be profitable. This is putting unhealthy trend in the sector and hampering whole country. People are working heard, valuable resources are being burnt and the country is hardly retaining anything, opined industry insiders.

Bangladesh, along with Pakistan, has the lowest level of mobile internet penetration in the Asia Pacific region, according to a report of GSMA, the global trade body of mobile operators.

Only 21 percent of the population of both Bangladesh and Pakistan have mobile internet connection -- the lowest among regional peers.

In 2017, one in five Bangladeshis subscribed to mobile internet services despite 3G networks covering in excess of 90 percent of the population.

Even countries like Nepal and Myanmar, both of which have lower GDP per capita than Bangladesh, have higher mobile internet penetration: 28 percent and 35 percent respectively.

Textile Engineering / Sweater exports on the rise
« on: April 21, 2018, 08:27:37 PM »
Sweater shipment from Bangladesh is on the rise thanks to competitive pricing and longer winters in the Western world as a result of climate change, exporters said.
Bangladesh exported sweaters worth $3.37 billion in fiscal 2016-17, up 5.64 percent year-on-year, according to data from the Export Promotion Bureau.



Source: EPB & BGMEA
Even three years ago, the window for sweater sales was at most four months, from November to February. Now, the window opens in October and continues until March.
The shift of work orders from China to Bangladesh is also another factor for the higher shipment, said Saif Ahmed, deputy general manager of Mohammadi Group, which exports nearly three million pieces of sweater in a year.
Seeing that the winter season has expanded in the Western world, almost all sweater manufacturers in Bangladesh have expanded their capacity, he said.
Besides, the knitwear is no longer used in the winter only; it is worn all year round, said Ahmed, who supervises the sweater section in Mohammadi Group.
Given the higher demand, most of the factories have also started automating their production line to boost output and cope with strict lead time.
However, the prices of knitwear have not increased but the costs of production have due to inefficient port operation and poor road conditions between Dhaka and Chittagong, Ahmed said.
In the long-term, Bangladesh's sweater business will increase, said a German buyer who purchases $1.3 billion worth of garment items from Bangladesh, 30 percent of which is knitwear.
In recent times, Vietnam and Cambodia have become major competitors of Bangladesh due to their shorter lead time, he said.
The lead time from Bangladesh is around 40 days, whereas it is 20 days from the other two Asian nations.
The reason for Bangladesh's longer lead time is that all knitwear is made from yarn imported from China, he said.
“Many Chinese companies have big investment in Vietnam and Cambodia. As a result, they can get yarns easily.” Regarding the prices, the German buyer said: “Even two years ago we paid $11 for a sweater, but now it is $9.”

Textile Engineering / January export earnings highest in 5 months
« on: April 21, 2018, 08:00:39 PM »
Exports brought home $3.41 billion in January -- the highest in five months -- thanks to a spike in shipments of garments, jute and jute goods and furniture.
Although 3.54 percent higher than a year earlier, January's receipts fell short of the $3.50 billion target for the month, according to data from the Export Promotion Bureau.

The amount takes the export earnings in the first seven months of fiscal 2017-18 to $21.32 billion, up 6.55 percent year-on-year. It, however, missed the seven-month target by $48.1 million.
Garment shipments, which typically account for more than 80 percent of Bangladesh's total export receipts, raked in $2.88 billion last month, up 6.67 percent.
Exports of leather and leather goods, the second largest export earning sector, fell 4.61 percent year-on-year to $709.51 million in the first seven months of the fiscal year.
Jute and jute goods, another top earner, fetched $661.86 million in the July-January period, up 17.36 percent from a year earlier.
Export of frozen fish, live fish and shrimp increased 7.55 percent to $353.99 million in the seven-month period.
Pharmaceuticals raked in $60.24 million in July-January, up 14.44 percent. Furniture shipment grew 34.33 percent to $31.77 million.
Agricultural products fetched $359.94 million, up 16.81 percent year-on-year.
The country shipped goods worth $34.66 billion in the last fiscal year and is aiming to earn $37.50 billion this fiscal year.

Textile Engineering / Danish retailers pay highest for apparel
« on: April 21, 2018, 07:51:17 PM »
Danish retailers pay the highest among the 28 European nations when it comes to garment items and the British ones the lowest, according to a survey by the International Apparel Federation.

The retailers from Denmark pay on average 9.56 euros per unit, followed by Italy at 9.15 euros and Germany at 8.63 euros. The UK retailers pay the lowest of 5.42 euros.

The IAF, the global federation of the apparel industry with presence in more than 60 countries, conducted the survey based on the average price of a pair of trousers imported by the European retailers in 2016. The survey result was published last December.

In fiscal 2016-17, Bangladesh exported $17.75 billion worth of apparel products to the EU, which is 50.96 percent of the total receipts, according to data from the Export Promotion Bureau.

“I do not agree with the findings of the survey,” said Mostafiz Uddin, managing director of Chittagong-based Denim Expert.

Spinning industry in Bangladesh has reached to a matured stage where mills are looking for consolidation and challenged with eroding margin and increasing cost of power and wages which were the strength a decade ago when SWOT analysis was done. But if we look at the total cost, power cost and labor cost; a decade ago power and labor costs were 7% and 3% while now these have reached to 10% and 6%, respectively. So, we are left with 84% that still we can work on to increase spinning profitability. The question is how?

Raw material is still under managed and unfocused which is roughly 60% of cost of goods sold and then is the productivity of our mills that is still minimum 10% less than the competing countries like India, Pakistan, China, Indonesia or Korea. Raw material and productivity alone can show the light to improve margin of spinning. Of course, in a matured market efficiency is required in all the areas with an overall strategic management plan. I believe interest rate is going to reach two digits soon and local currency is going to be devalued and these challenges should become issues in the near future. Capital market is still not a source of fund and I wish these should be important part of financing plan.

We also need to be prepared for the consequences of the exit from LDC status that is expected beyond 2021. However, I don’t want to demine prospect of spinning in Bangladesh at all but it is always better to do the homework and prepare for the battle earlier than it hits us suddenly. I rather believe that within next five years’ size of spinning industry would increase by 50%. I would like to share my ideas where these investments in spinning may concentrate:

Replacement of inefficient machinery and equipment: This may be the major area of investment, roughly 40%. Technology development in power generation over last 20 years has allowed a generator of 1 mega be replaced with a 1.5 mega generator and it would consume the same amount of fuel (Gas). A card of 1997 that could produce 42 kg per hour can now produce 90 kg almost with the same power and space. Focus would be on replacement of major spinning components like motors, spindles, rings, and systems (Humidification, waste minimization and recycling, SCM, ERP, MIS, PMS, QMS, HRM, SOP, etc.) to make spinning energy efficient, productive and profitable. These replacement decisions are being made gradually and expected to get momentum in future.
New investment and expansion in 100% cotton yarn spinning: Second major investment roughly 30% may be in this section. As the garment export and domestic market is growing investment in spinning is increasing. Bangladesh is predominately a cotton knit garment exporter and requires cotton ring carded and combed yarn. So, ring investment would be focused in mostly carded with auto-doffing and compact attachment. Now average count is Ne 30/s and at least 10% would focus on Ne 40/s+ and 15% in combed compact knitting and weaving yarn. Due to rise of denim investment ring as well as rotor spinning would come in courser counts that would be the rest 5%.
New investment and expansion in blended yarn spinning: About 15% investment may come in this sector. Blended yarn investment would be dominated by air jet spinning or Vortex. Not only Vortex market is expanding, in order to ensure quality, particularly pilling, Vortex yarn is in advantageous position over ring yarn. Also costing of Vortex yarn is advantageous over ring yarn.
Specialty yarn: Rest 15% investment may come in this section. It would be dominated by yarn that has demand but are less available locally like recycled yarn, new and specialty blended yarn, special count yarn, and mélange yarn.
The focus would be to produce efficiently and run with marginal profit and manage unsystematic risks across the spinning process from planning, material, process, system, marketing, finance, currency, interest and capital market, and people. I believe worker and management team would work hand in hand to successfully manage spinning business profitably through the direction and support from our leaders, the entrepreneurs and government would provide the necessary infrastructure and policy guidelines ideal for sustainable growth and business.

Textile Engineering / Bangladesh producing eco-friendly jeans
« on: April 02, 2017, 06:03:57 PM »
Bangladesh producing eco-friendly jeans
Bangladesh has 67 garments factories already that have the Leadership in Energy and Environment Design (LEED) certificates and around 220 garments factories are in the pipeline to get the LEED certificates soon. The information was revealed to The Independent by the founder of Denimsandjeans, SandeepAgarwal.
LEED provides green building certificates worldwide. This shows that keeping environmental sustainability in mind, Bangladesh is building more eco-friendly factories.
Agarwal was speaking to The Independent at the seventh edition of ‘Denimsandjeans Bangladesh’, an exposition of jeans products, which concluded in Dhaka on Thursday.
Asked about the importance of green factories, Agarwal replied that making the factories eco-friendly has become more important worldwide because the planet is turning out to be more vulnerable for its inhabitants by the day.
Bangladesh earns around EUR 1.3 billion every year by exporting denim jeans and stands number one in the European market. This shows the massive opportunities that lie in building more green factories that will produce denim jeans in a sustainable, environment-friendly and productive manner, he added.
A Spanish company, Jeanologia, which has participated in the Denimsandjeans expo, specialises in the development of sustainable technologies for garments. The company presented its new ‘e-flow technology’.
This correspondent asked the project manager of Jeanologia, Fabien Liautard, about the working pattern of ‘e-flow technology’. He replied that the traditional method is to wash functional denim fabrics in water. E-flow technology uses air and has basically two different parts: laser and eco.
“e-flow technology gets the air from the atmosphere and transforms it into nano-bubbles. These bubbles consume minimum proportions of water and functional elements that are not harmful for the environment,” Liautard said.
The marketing officer of Jeanologia, KaziNahidulAlam, said that by using e-flow technology, an exact amount of chemicals are used on denim jeans and none of it is wasted. So, there is no chance of emitting excess chemicals that are harmful to the environment.
He explained that the traditional method needs 1,800 litres of water to wash 100 kg of denim garments, while the e-flow method uses only 30 litres of water to wash 100 kg of denim jeans.
He also added that e-flow technology saves 1,770 litres of water compared to the traditional method. It is entirely sustainable and environment-friendly for the product.
Envoy Textiles Ltd is a renowned denim jeans manufacturer in Bangladesh. It has got the Platinum award from LEED.
Envoy marketing manager Asif Wares Khan told this correspondent that Envoy uses a water treatment plant to wash the denim fabrics. “It is a modern technology. It recycles water and is not hazardous for the environment,” he said.
Product sustainability is the prime concern for any manufacturing industry, especially readymade garments, because it emphasises environmental, social and economic benefits without harming the environment. It gets product benefits too.
The event manager and cofounder of Denimsandjeans Bangladesh, RubaiyatAhsan, said that natural dyes derived from plants, invertebrates or minerals are being used to dye denim fabrics in Bangladesh for quite some time.
“This discharges less emission and is not harmful for the environment at all,” Ahsan added.
Rubaiyat also told The Independent that in the near future, the export market of denim jeans would exceed the market of the woven fabric because the price of woven products is not increasing as compared with denim fabrics or jeans.
Garment factories like Ha-Meem Group, Shasha Denims Ltd, and Envoy Group produce top-quality denim jeans in Bangladesh and export these, said Ahsan.
According to Denimsandjeans officials, Bangladesh is the second largest jeans exporter in the world after China. Currently, 29 renowned mills are producing denim jeans in Bangladesh.
Around 28 companies from Bangladesh, Turkey, India, China, Germany, Spain, Brazil, Pakistan, Hong Kong, among others, participated in the expo to showcase their denims, fabrics and latest accessories.
