Concept of IE

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 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
