Important Formula for Industrial Engineering (IE) Students & Professionals

Concept of Industrial Engineering (IE):
In the garment industry, industrial engineering (IE) refers to the application of engineering principles to optimize production processes, increase efficiency, and reduce waste. Industrial engineers analyze and design production systems, develop and implement production plans, and improve the overall productivity of the manufacturing process.

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. The formula for Industrial Engineering is might to know every textile student and professionals.

Industrial engineers (IEs) are responsible for designing integrated systems of people, machines, materials, 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 (IE) Students & Professionals

1. Line Labor Productivity:Industrial Engineering Line Labor Productivity

2. Line Machine Productivity:

Industrial Engineering 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 = (Manpower * 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 / Bottleneck 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 the operator: Required no of operator = Target daily output / Daily output per operator

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

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

  2. Thank you for this excellent post. I have just started to read this article carefully. Keep up posting these type of post contuniously.
