Question: A copy machine is available 24 hours a day. On a typical day, the machine produces 102 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 17% of the jobs need to be reworked, in which case the set-up time and the processing time have to be repeated. The other time, the equipment is idle. What is the OEE of the equipment?
