Important Formula For IE Department.

01. Target No. of worker x working hour x 60 / SMV x expected efficiency. 02. Target 60/SMV. 03. Line/Team target  (60/SMV)x Present worker x Organization efficiency . 04. Target per day  Working hour x 60 x No. of operator / Target SMV. 05. Capacity Average of total observe time x 1.66 + 15% 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 SMV x Production / 60. 21. Available hour Working hour x Use machine. 22. Performance (Earn hour / Available hour - Off standard time) x 100. 23. Improvement 1-(Production / Capacity). 24. Balancing efficiency 1-Balancing loss. 25. Balancing loss AML-TML/AMLx100. 26. Standard time Net operation time x (1+ Ratio of loss time). 27. Daily output Working hours (seconds) + Standard time. 28. Output per operator Work hours (second) / Total time of operations. 29. Required No. of operators Targeted daily output / Daily output per operator. 30. Target daily capacity Daily work hours / Standard process time (SPT). 31. Daily capacity per worker Daily capacity / No. of workers = Daily Work hours / Standard total processing. 32. Organization efficiency Pitch time / Bottle neck process time (x100) = 100/140 x 100 = 71.4% 33. Upper limit Pitch time / Target organization efficiency = 100 / 0.85 = 117.6 seconds. 34. Lower limit 2 x Pitch time - Upper limit = 2 x 100 - 117.6 = 82.4 seconds. 35. Planned daily work flow Daily work hours / Standard process time (SPT) x organization efficiency. 36. Accumulated avarage time Daily work hours/AccumulatedxNo.of daysxstandard No.of workers in the group/No. of pieces produced. 37. SMV Basic time + Allowance time + bundle time. 38. DHU No. of deffect 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 + Jute kg + Wastage fabric kg) 41. 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%. 40. Fabric consumption (Inch) Length x chest x 2 x GSM / 1000 / 1550 x 12 + Wastage%. TML Theoratical machine level. AML Actual machine level. AQL  Acceptable quality level. PMTS Pre method time study. GSM Gram squire per miter. BHT Bundle handle time. SUM Standard allocated minutes. TS Technical allowance. TP Personal allowance. TER Recovery allowance. TV Total allowance. WH Working hour.
