9 Losses-?????????? ????? ??????. 1. Start up loss : Time taken to produce the first product from the time that machine is activated. 2. Set up & adjustment loss: idling time erupted to the obtain the required specification of the relevant product 3. Brake down time: Idling time caused by the failure of a machine/Machines
9 Losses -?????????? ????? ??????. 4. Change over loss: Time loss happened due to the stopping of production for the change over. 5. Labour/Material shortage: It is the shortage of out put to the production target, expressed as a time value. 6. Minor stoppages: It is the sum of total time that stop the production for less than 5 minutes 7. Cleaning time : It is the time that the production can¡¯t be planned due to the cleaning requirement of the process.
9 losses -?????????? ????? ??????. 8. Speed loss: It is the shortage of out put compared to the machine capacity, expressed as a time value. 9. Defect & rework loss: It is the total amount of nonconforming out put, expressed as a time value.

OEE % = Availability % *Performance %*Quality % How to calculate OEE
How to calculate-Availability Availability % = (Operating time /planned time)*100 Operating time = Planned time ¨CIdle time Idle time Start up loss Labor & material shortage Set up & adjustment loss Minor stoppages Change over time Cleaning time Break down time
How to calculate ¨CPerformance & Quality Performance % =( actual rate/ Rated capacity)*100 Actual rate = Total out put/operating time Quality % = (Good out put/Total out put)*100 Good out put = Total out put ¨CDefect & rework
Example Planned time = 12hours Capacity =100kg/hr Total Out put = 900kg Defect & rework = 10kg Brake down =0.5 hours Start up time = 0.5 hrs Change over time = .5hrs Set up adjustment time = 0 Minor stoppages = 0.5hrs Cleaning time = 0 Material/labour shortage= 0 ? Availability% = ? Actual rate = ? Performance %= ? Good out put = ? Quality % = ? OEE= ((12-2)/12)*100= 83.3% 900kg/10hrs=90kg/hr (90/100)*100=90% 900-10=890kg (890/900)*100=98.8% 83.3%*90%*98.8%=74.16%
