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%
