Shaker Table Utilization at 98% target utilization: a worked example

Push target utilization up to 98% and the picture changes. This example computes every intermediate figure at that operating point. a vibration lab manager needs to know whether a shaker table schedule is overbooked or underused

The inputs for this scenario

  • Booked shaker time: 142 hr (unchanged)
  • Available shaker time: 168 hr (unchanged)
  • Target utilization: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Shaker utilization = booked shaker time รท available shaker time) to the inputs above produces each figure below.
  • At this operating point the engine returns 84.52 % for shaker utilization, the number this scenario is built around.
  • At this operating point the engine returns 13.48 points for gap to target.
  • At this operating point the engine returns 142 hr for booked time.
  • At this operating point the engine returns 168 hr for available time.

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. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Shaker utilization: 84.52 % (headline result)
  • Gap to target: 13.48 points
  • Booked time: 142 hr
  • Available time: 168 hr
