how to calculate the OEE for a equipment?

Answer Posted / arun

Overall Equipment Effectiveness is based on 3 factors

1. Availability rate
2. Performance rate
3. Quality rate

(Some companies use usability rate also)

1. Availability rate for machine - Total running time
divided by total hours available
2. Performance rate - Total number of componants produced
divided by total number of componants that is supposed to
be produced
3. Quality rate - total number of quality products produced
divided by total number of products produced
4. usability rate - total hours machine has run divided by
total hours available (Usability talks about usage of order
for that machine)

OEE - Availability rate x performance rate x quality rate
