Calculate the availability component of OEE using the data: Scheduled to run 16 hours a day, 5 days a week; Planned stop production 60 min each day for 5S activities; Lost 3 hours this week due to machine breakdowns; Lost 2 hours this week due to material shortages.

• B. 92%

• D. 88.8%

Answer: (A)

Availability in OEE is the portion of the time that was actually available for production after removing planned stops, relative to the time allocated for production. In other words, it compares what you could have produced during the planned production time to what you actually produced. First, find the time the line was scheduled to run: 16 hours per day for 5 days equals 80 hours. Then remove planned stops to get the planned production time: 60 minutes per day for 5 days equals 5 hours, so planned production time is 80 − 5 = 75 hours. Unplanned downtime reduces actual operating time, not the planned production time: breakdowns plus material shortages total 3 + 2 = 5 hours. So actual operating time is 75 − 5 = 70 hours. Finally, compute availability: actual operating time divided by planned production time = 70 / 75 = 0.9333, or about 93.3%.
