Mixer Utilization at 58% target utilization rate: a worked example

This worked example runs the mixer utilization numbers for a tougher week than the baseline: 58% target utilization rate instead of the typical 80%. Calculate disperser or mixer utilization from running hours versus available hours and compare it against your target.

The inputs for this scenario

  • Disperser running hours: 120 hr (held at the documented default)
  • Available mixer hours: 168 hr (held at the documented default)
  • Target utilization rate: 58 % (the input this scenario stresses; the baseline uses 80)

Working through the calculation

  • The calculation starts from the formula this tool documents: Mixer utilization rate = disperser running hours / available mixer hours * 100.
  • Mixer utilization rate works out to 71.43 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target utilization works out to -13.43 points at these inputs.
  • Disperser running hours works out to 120 hr at these inputs.
  • Available mixer hours works out to 168 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target utilization rate sits at 80% and the headline result is 71.43 %, this scenario lands almost exactly on the baseline at 71.43 %.
  • Use it in a weekly or shift review to see how much of the mixer's available time turned into actual dispersing and where idle time is hiding. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Mixer utilization rate: 71.43 % (headline result)
  • Gap to target utilization: -13.43 points
  • Disperser running hours: 120 hr
  • Available mixer hours: 168 hr

Run it with your numbers
