Shaker Table Utilization at 61% target utilization: a worked example

Suppose target utilization falls to 61%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate booked shaker table time as a percent of available lab time and compare against a utilization target.

The inputs for this scenario

  • Booked shaker time: 142 hr (held at the documented default)
  • Available shaker time: 168 hr (held at the documented default)
  • Target utilization: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Shaker utilization = booked shaker time รท available shaker time.
  • Shaker utilization works out to 84.52 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -23.52 points at these inputs.
  • Booked time works out to 142 hr at these inputs.
  • Available time works out to 168 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target utilization sits at 85% and the headline result is 84.52 %, this scenario lands almost exactly on the baseline at 84.52 %.
  • It divides booked shaker hours by available shaker hours to give a utilization percentage, then compares it to your target. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Shaker utilization: 84.52 % (headline result)
  • Gap to target: -23.52 points
  • Booked time: 142 hr
  • Available time: 168 hr
