Robot Idle Time with scheduled cell minutes of 1,200 min: a worked example

What does the result look like when scheduled cell minutes reaches 1,200 min? The full calculation is worked below with real intermediate numbers. Use it when chasing minor stops in a robot cell so you can see how much idle time is left after known losses and where to attack it first.

The inputs for this scenario

  • Scheduled cell minutes: 1,200 min (raised for this scenario; the documented default is 480)
  • Robot in-cycle minutes: 360 min (unchanged)
  • Blocked-by-downstream minutes: 45 min (unchanged)
  • Starved-by-upstream minutes: 30 min (unchanged)

Working through the calculation

  • Applying the documented formula (Tracked robot time = robot in-cycle minutes + blocked-by-downstream minutes + starved-by-upstream minutes) to the inputs above produces each figure below.
  • At this operating point the engine returns 765 min idle for remaining robot idle time, the number this scenario is built around.
  • At this operating point the engine returns 435 value for tracked robot time.
  • At this operating point the engine returns 1,200 value for scheduled cell minutes.
  • At this operating point the engine returns 63.75 % for utilization.

How this compares with the baseline

  • Against the tool's baseline example, where scheduled cell minutes sits at 480 min and the headline result is 45 min idle, this scenario comes in 1,600% above the baseline at 765 min idle.
  • A figure at this level is achievable when scheduled cell minutes is genuinely sustained, not just peaked for a shift. It only shows how much idle is unexplained, not why; the 45 remaining minutes still need direct observation or controller logs to attribute.

Results at a glance

  • Remaining robot idle time: 765 min idle (headline result)
  • Tracked robot time: 435 value
  • Scheduled cell minutes: 1,200 value
  • Utilization: 63.75 %
