9 Losses- ඵලද�යිත�වයා අඩුවන අව;ථා�.

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 - ඵලද�යිත�වයා අඩුවන අව;ථා�.

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 - ඵලද�යිත�වයා අඩුවන අව;ථා�.

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.

How to calculate OEEOEE % = Availability % *Performance %*Quality %

How to calculate-Availability

Availability % = (Operating time /planned time)*100

Operating time = Planned time –Idle time

Idle time Start up loss Labor & material shortage Set up & adjustment loss Minor stoppagesChange over time Cleaning timeBreak down time

How to calculate –Performance & 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 –Defect & rework

Example

Planned time = 12hoursCapacity =100kg/hrTotal Out put = 900kgDefect & rework = 10kgBrake down =0.5 hoursStart up time = 0.5 hrsChange over time = .5hrsSet up adjustment time = 0Minor stoppages = 0.5hrsCleaning time = 0Material/labour shortage=

• 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%
