Question

a copier in a government office is available 600 minutes per day (the building is closed the rest of the day). this time can be categorized as follows: 195 minutes per day, the copier sits idle. breakdowns and routine maintenance (replacing toner, adding paper, etc.) takes 45 minutes per day. setting up jobs takes 35 minutes, and reprinting jobs that were not set up correctly takes 50 minutes per day on average, while 20 minutes per day is spent waiting for paper jams to be cleared. the rest of the time is value added time.

what is the overall equipment efficiency for the copier?

Explanation:

Step1: Calculate total non-value time

$195 + 45 + 35 + 50 + 20 = 345$ minutes

Step2: Find value-added time

$600 - 345 = 255$ minutes

Step3: Compute OEE ratio

$\text{OEE} = \frac{\text{Value-added Time}}{\text{Total Available Time}} = \frac{255}{600}$

Step4: Convert to percentage

$\frac{255}{600} \times 100\% = 42.5\%$

Answer:

42.5%
