Cement Plant OEE at 99% performance: a worked example

This scenario runs the cement plant oee calculation on the strong side: 99% performance, with every other input held at its documented default. Use it to benchmark line effectiveness and target the biggest loss in Building Materials Manufacturing.

The inputs for this scenario

  • Operating (run) time: 410 min (unchanged)
  • Planned production time: 480 min (unchanged)
  • Performance: 99 % (raised for this scenario; the documented default is 95)
  • Quality (first-pass yield): 98 % (unchanged)

Working through the calculation

  • Applying the documented formula (Availability = operating time ÷ planned production time) to the inputs above produces each figure below.
  • At this operating point the engine returns 82.87 % for oee, the number this scenario is built around.
  • At this operating point the engine returns 85.42 % for availability.
  • At this operating point the engine returns 99 % for performance.
  • At this operating point the engine returns 98 % for quality.

How this compares with the baseline

  • Against the tool's baseline example, where performance sits at 95% and the headline result is 79.52 %, this scenario comes in 4.21% above the baseline at 82.87 %.
  • Use it on any continuous cement asset — kiln, raw mill, cement mill, or packing line — when you have run time, planned time, and reasonable performance and quality estimates. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
