Concept of IE
The garment manufacturing and exporting industry is facing heavy challenges due to various factors including global competition, production costs increase, less productivity/efficiency, labor attrition, etc. the basic fact that our country has immense strength in human resources itself is the motivating aspect to feel for such an analysis. For overcoming those challenges our need industrial engineering knowledge.

Industrial engineers (IEs) are responsible for designing integrated systems of people, machines, material, energy, and information. Industrial engineers figure out how to do things better. They engineer processes and systems that improve quality and productivity. They work to eliminate waste of time, money, materials, energy, and other resources. This is why more and more companies are hiring industrial engineers and then promoting them into management positions. .

We can see at a glance of IE, 

Industrial Engineering (IE) = Production ↑ Cost ↓ Proper use of all elements ↑ Efficiency ↑ Profit ↑

I’m giving some formula for Industrial engineering students or professionals. If those help them then I will be thankful.
Important Formula for Industrial Engineering
1. Line Labor Productivity:
2. Line Machine Productivity:
3. Line Efficiency:
4. Theoretical Manpower: 
5. Target:
6. Standard Pitch Time (S.P.T) = Basic Pitch Time (B.P.T) + Allowances (%)

7. GSD
GSD = (Man power * Work hour) / Target

8. SMV
SMV = Basic time + (Basic time * Allowance)

9. Basic time
Basic time = Observed time * Rating

10. Observed time
Observed time = Total Cycle time / No of cycle

11. Rating
Rating = (Observed Rating * Standard rating) / Standard rating

12. Earn minute
Earn minute = No of Pc’s (Production) * Garments SMV

13. Available minute
Available minute = Work hour * Manpower

14. Organization Efficiency
Organization Efficiency = (Basic pis time / Bottle neck time) * 100

15. Basic pis time (BPT)
Basic pis time = Total GMT SMV / Total Manpower

16. UCL

UCL = Basic pis time / Organization Efficiency

17. LCL
LCL = 2 * Basic pis time – UCL

18. Capacity
Capacity = 60 / Capacity time in minute

19. Cycle Time
Cycle Time = 60 / Team target

20. Capacity Achievable
Capacity Achievable = Capacity * Balance

21. Daily output
Daily output = Work hour / SMV

22. Factory capacity
Factory capacity = (Work hour / SMV) * Total worker * Working day * Efficiency

23. CPM
CPM = (Total over head cost of the month / No of SMV earners Work minutes) *Efficiency

24. Required no of operator
Required no of operator = Target daily output / Daily output per operator

25. Efficiency
Efficiency = (Earn minute * Available minute) * 100

  3. Fucking formula"Efficiency =(Earn minute*Available minute)*100"."GSD=(Man power*Work hour)/Target"."Organization Efficiency =(Basic pis time/Bottle neck time)*100"
