The Rich History of Bangladesh: From Ancient Times to Modern Day

The Rich History of Bangladesh From Ancient Times to Modern Day

Bangladesh, a country with a rich and diverse history, has seen the rise and fall of numerous empires, the spread of various religions, and significant political changes. This article delves into the history of Bangladesh, highlighting key events and periods that have shaped the nation.

Ancient Bengal: The Early Civilizations

The history of Bangladesh dates back over four millennia to the Chalcolithic period. Early Bengal was characterized by a succession of Hindu and Buddhist kingdoms and empires. The region was known for its rich culture and trade.

The Mauryan and Gupta Empires

During the 3rd century BCE, the Mauryan Empire extended its influence into Bengal, promoting Buddhism. The Gupta Empire, which followed, saw the re-establishment of Hinduism, although Buddhism continued to flourish.

The Pala and Chandra Dynasties

The Pala dynasty (8th–12th century) and the Chandra dynasty (10th–11th century) were significant in the history of Bengal. The Palas were patrons of Buddhism, while the Chandras supported both Hinduism and Buddhism.

The Arrival of Islam

Islam arrived in Bengal in the 8th century and gradually became dominant from the early 13th century with the conquests led by Bakhtiyar Khalji and the activities of Sunni missionaries like Shah Jalal.

The Bengal Sultanate

From the 14th century onward, Bengal was ruled by the Bengal Sultanate, founded by Fakhruddin Mubarak Shah. The Sultanate expanded under rulers like Shamsuddin Ilyas Shah, leading to economic prosperity and military dominance.

The Mughal Empire

Bengal became a part of the Mughal Empire in the 16th century. It was one of the wealthiest provinces of the empire, contributing significantly to its economy.

The British Colonial Period

Following the decline of the Mughal Empire, Bengal became a semi-independent state under the Nawabs of Bengal. The British East India Company conquered Bengal after the Battle of Plassey in 1757, marking the beginning of British colonial rule.

The Partition of Bengal

The borders of modern Bangladesh were established with the partition of Bengal between India and Pakistan during the Partition of India in 1947. The region became East Pakistan as part of the newly formed State of Pakistan.

The Road to Independence

The Proclamation of Bangladeshi Independence in March 1971 led to the nine-month-long Bangladesh Liberation War, which culminated in the emergence of the People’s Republic of Bangladesh.

Post-Independence Era

Since gaining independence, Bangladesh has faced political instability, economic reconstruction, and social transformation. The country experienced military coups and authoritarian rule, notably under General Ziaur Rahman and General Hussain Muhammad Ershad.

The Restoration of Democracy

The restoration of parliamentary democracy in the 1990s saw power alternate between the Awami League and the Bangladesh Nationalist Party (BNP).

Economic Growth and Challenges

In recent decades, Bangladesh has achieved significant economic growth, emerging as one of the world’s fastest-growing economies, driven by its garment industry, remittances, and infrastructure development. However, it continues to grapple with political instability, human rights issues, and the impact of climate change.

Conclusion

The history of Bangladesh is a testament to its resilience and ability to overcome challenges. From ancient civilizations to modern-day economic growth, Bangladesh’s journey is marked by significant events and periods that have shaped its identity.

Efficiency Calculations for the Garment Industry

Precision in Apparel Efficiency Calculations for the Garment Industry

Efficiency calculations pivotal to the textile trade. From fabric requirements to cost analysis, embark on a journey to master the precision needed for success in the dynamic realm of fashion manufacturing.

01. Target = 60 ÷ (SMV x No. of worker x working hour x expected efficiency).

02. Target = 60÷SMV.

03. Team target =(60÷SMV) x Present operator x Organization efficiency.

04. Target per day = Working hour x 60 x No. of operator / Target SMV.

05. Capacity=Average of total obserb time x 1.66 + 30% Allowance / 60.

06. Factory capacity=No. of operator x working minutes + Present % x average factory efficiency.

07. Capacity per day = Present operator x working hour x organization efficiency x Attendance.

08. Weekly capacity = No. of operators x Absenteesm x Clock minutes per week x Average factory efficiency.

09. Marker efficiency = Area of patterns in the marker / Total area of the marker x 100.

10. Load = (Contract size x work content) contract 1+ (Contract size x work content)

Contract 2 + etc.

11. Load = Order quantity x Work content (SMV of garments).

12. Observe time = Total cycle time / No. of cycle.

13. Basic time = Avarage of observe time X Rating %.

14. Sam = Basic time x Allowance.

15. Rating = Observe time x Standard rating / Standard rating.

16. Cycle time = 60 / Team target.

17. Pitch time = Total SMV / Present operator.

18. Efficiency = Earn hour / Available hour x 100

19. Efficiency = SMV / Total time.

20. Earn hour = (Production x SMV) / 60.

21. Available hour = Working hour x Use machine(Total manpower)

22. Performance = (Earn hour / Available hour – Off standard time) x 100.

23. Improvement = 1-(Production / Capacity).

24. Balancing efficiency = 1-Balancing loss.

25. Loss pcs = (60/SMV)x Available hours x avg factory effi (61%) -Q.C Pass

26. Balancing loss = AML-TML/AMLx100.

27. Standard time = Net operation time x (1+ Ratio of loss time).

28. Daily output = Working hours (seconds) + Standard time.

29. Output per operator = Work hours (second) / Total time of operations.

30. Required No. of operators = Targeted daily output / Daily output per operator.

31. Target daily capacity = Daily work hours / Standard process time (SPT).

32. Daily capacity per worker = Daily capacity / No. of workers = Daily Work hours / Standard total processing.

33. Organization efficiency = Pitch time / Bottle neck process time (x100) = 100/140 x 100 = 71.4%

34. Upper limit = Pitch time / Target organization efficiency = 100 / 0.85 = 117.6 seconds.

35. Lower limit = 2 x Pitch time – Upper limit = 2 x 100 – 117.6 = 82.4 seconds.

36. Planned daily work flow = Daily work hours / Standard process time (SPT) x organization efficiency.

37. Accumulated avarage time = Daily work hours/AccumulatedxNo.of daysxstandard No.of workers in

The group/No. of pieces produced.

38. SMV = Basic time + Allowance time + bundle time.

39. DHU = No. of defect observe / No. of garments checked.

39. Booking fabric K.G. = Order quantity / 12 x Fabric consumption per doz.

40. Garments K.G. = Total receive fabric kg – (Save return kg + Jhute kg + Wastage fabric kg)

40. Input to sewing pcs. = Total in pcs – (Print Embroidery short & wastage + Cutting wastage pcs.)

39. Fabric consumption (CM) = Length x chest x 2 x GSM / 1000 / 10000 x 12 + Wastage%.

41. Fabric consumption (Inch) = Length x chest x 2 x GSM / 1000 / 1550 x 12 + Wastage%
