The basic requirement for production management and each people who are working in production .

In this post, I have explained the calculation procedure :-

The total number of garments stitched by operators in a line in a day.

also termed as daily output.

  1. How many operators are working in the line?
  2. How many hours line will work in a day?
  3. Average Line efficiency level?
  4. SAM of the garment (Standard allowed minutes)

FORMULA:-

Daily production = (Total man minutes available in a day/SAM) * Average Line efficiency
Total available man-minutes =(Total no. of operators * Working hours in a day * 60)

  • Garment SAM is 25 minutes, 
  • Number of operators is 60 
  • Shift hours in a day = 8 hours
  • Average line efficiency =50
  • Operators get a total of 45 minutes for lunch and tea break.
So, Total available man minutes = 60 *( (8 * 60) – 45) )= 26,100 minutes

Daily estimated production = 26100 /25 * 50% = 522 pieces

The number of operators and working hours. And production is reverse proportional to the garment SAM. 

efficiency of a line increases you can expect higher production.

Anyone of the followings can reduce production of the assembly line. So to get estimated output, you have to take on the following areas.

  • Machine breakdown
  •  (WIP control)
  • No feeding of cuttings
  • Quality issues
  • Low operator performance 
  • Operator absenteeism
