A copy machine is available 24 hours a day. On a typical day, the machine produces 100 jobs. Each job takes about 3 minutes on the machine, 2 minutes of which is processing time and 1 minute is setup time (logging in, defining the job). About 20 percent of the jobs need to be reworked, in which case the setup time and the processing time have to be repeated. The remainder of the time, the equipment is idle. What is the OEE of the equipment?

Answer:

13.3%

Explanation:

OEE= Availability × Performance × Quality

Availability = Run Time/ Planned Production Time

Run time = 3*100 = 300 + 0.2* 300 = 1.2 *300 = 360 mins

Planned Production time = 24*60 = 1440 mins

Availability = 360/1440 = 1/4 = 25%..............1

Performance = (Ideal Cycle Time × Total Count) / Run Time

Ideal Cycle Time = 2 min (Only the processing time)

Total Count= 100+20 = 120

Performance = 2*120/360 =66.67% .............2

Quality = 100%-20% = 80%.......3

OEE=25% * 66.67 % * 80% =

0.13334=13.3%
