Required Run Rate with remaining quantity to produce of 380 units: a worked example

This scenario runs the required run rate calculation on the strong side: remaining quantity to produce of 380 units, with every other input held at its documented default. Use this calculator when you receive a rush order or have limited time remaining in a shift and need to determine how fast the line must run to complete the order on time.

The inputs for this scenario

  • Remaining quantity to produce: 380 units (raised for this scenario; the documented default is 150)
  • Available time remaining: 4 hrs (unchanged)
  • Expected efficiency: 0.85 decimal (unchanged)

Working through the calculation

  • Applying the documented formula (Required Run Rate = Remaining Quantity / (Available Time x Efficiency)) to the inputs above produces each figure below.
  • At this operating point the engine returns 0.81 units / hr for effective rate accounting for efficiency, the number this scenario is built around.
  • At this operating point the engine returns 95 units / hr for raw throughput.
  • At this operating point the engine returns 0.85 % for expected efficiency factor.
  • At this operating point the engine returns 4 hr for available time remaining.

How this compares with the baseline

  • Against the tool's baseline example, where remaining quantity to produce sits at 150 units and the headline result is 0.32 units / hr, this scenario comes in 153% above the baseline at 0.81 units / hr.
  • Use it mid-run or mid-shift when you're behind plan and need to know whether catch-up is feasible and at what pace. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Effective rate accounting for efficiency: 0.81 units / hr (headline result)
  • Raw throughput: 95 units / hr
  • Expected efficiency factor: 0.85 %
  • Available time remaining: 4 hr
