Robot Availability at 68% speed performance rate: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop speed performance rate to 68%, then walk the calculation through step by step. Estimate robot availability as operating time over planned production time, then combine with performance and quality factors for an OEE-style effective availability.

The inputs for this scenario

  • Robot available run time: 420 hr (held at the documented default)
  • Total scheduled cell time: 480 hr (held at the documented default)
  • Speed performance rate: 68 % (the input this scenario stresses; the baseline uses 95)
  • Good-output quality rate: 98 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Robot availability = robot operating time / planned production time.
  • Effective robot availability works out to 58.31 % available at these inputs, and this is the headline figure for the scenario.
  • Base availability works out to 87.5 % at these inputs.
  • Performance factor works out to 68 % at these inputs.
  • Quality factor works out to 98 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where speed performance rate sits at 95% and the headline result is 81.46 % available, this scenario comes in 28.42% below the baseline at 58.31 % available.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to speed performance rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses single performance and quality factors as flat multipliers, so it summarizes rather than diagnoses where specific speed or scrap losses occur.
