Industrial Engineering Formula


Industrial Engineering Formula

Industrial engineering is various principles and techniques applied in different contexts. Here are some commonly used formulas in industrial engineering:






  1. Daily Line Target =(Total Working minutes in a day ×No.of operators×Line Efficiency %)/(SMV/SAM)
  2. Individual Operator target=(Total Working minutes in a day×Line efficiency%)/(operation SMV/SAM)
  3.  Operator Efficiency% (individual)=  (Total pieces produced×operation SMV/SAM×100)/(Total Minutes Worked)
  4. Line  Efficiency%=(Line output ×Garment SAM/SMV×100)/(Total no.of operators×Minutes Worked)
  5. Machine  Productivity=(Line Output(pieces))/(number of machine used)
  6. Labour Productivity=(Line output (Pieces)/(Number of  workers (including operator and helper))
  7. Line work in process (WIP)=Total pieces-Total output
  8. Standard time=(Observed time×Observed Rating )+Allowances
  9. Machine  Utilization%=(Actual machine running time ia working day ×100)/(Total  time available  in working  day)
  10. Cost per minute=(Total cost incurred in labour)/(Total  available working minutes in a day×No.  of labours)
  11. Production Cost per Unit=(Total production  cost incurred in a day)/(total garments produced in a day)
  12. Man to Machine Ratio=(Total workforce in a factory)/(Number of utilized machine)

Difference between SMV & SAM

  Difference between SMV & SAM SAM means the Standard Allowed Minutes and SMV means Standard Minute Value are both primarily used in the garments manufacturing industry. These two topics are industrial engineering terms. And primarily used in industry to measure and manage work performance, efficiency, and productivity. These subjects play in a crucial role in optimizing production processes, enhancing efficiency, and regulating the costs   SAM (Standard Allowed Minutes) Standard Allowed Minutes is the time-based measuring system that is used to evaluating of the time required to complete a specific work or operation. It serves as a standard reference for work measurement and performance evaluation. SAM is usually expressed in minutes per operation or task and is determined through thorough time and motion studies. Applications of SAM In garment manufacturing, SAM is used for various purposes, such as: Establishing production targets: By knowing the SAM for each...

Efficiency and Productivity

  Difference between Efficiency and Productivity in the garments industry Efficiency and productivity are the two most important subjects in the garment industry. Efficiency is measured by the utilization of resources to produce the output. It is calculated as the ratio of output to input. For example, if a garment factory has 100 garments in a day using 10 workers, then the efficiency of the factory is 10 garments per worker per day. On the other hand, Productivity is a measure of how much output is produced from a given set of inputs. It is calculated as the ratio of output to total factor input. Total factor input includes all the resources used to produce output, such as labor, capital, and materials. For example, if a garment factory has 100 pieces of garments in a day using 20 workers and 1000 TK  in materials, then the factory's productivity is 5 garments per worker per day/1000 TK in materials. In the garment industry, efficiency is often measured at the level ...
