Question

A copy machine is available 24 hours a day. On a typical day, the machine produces 88 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 23 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?

	(Round your percentage answer to 1 decimal place.) What is the OEE of the equipment? percent

Answer 1

OEE = Value added time / Total time

In this case Value added time is the time when jobs are actually processed. It does not include jobs that are reworked.

Value added time = (88*2) minutes

Total time = 24*60 minutes

OEE = 12.2%
