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.
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 overhead 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
