Industrial Heat Pumps & Electrified Thermal Systems worked example

Production Ramp Capacity at 94% expected line uptime during ramp: a worked example in industrial heat pumps & electrified thermal systems

What does the result look like when expected line uptime during ramp reaches 94%? The full calculation is worked below with real intermediate numbers. Use it when operations and launch teams need to compare ramp plans with real assembly, test, supplier, and quality constraints for new heat pump products.

The inputs for this scenario

  • Heat pump units assembled per build cycle: 3 units / cycle (unchanged)
  • Planned build cycles in the ramp window: 80 cycles (unchanged)
  • Expected line uptime during ramp: 94 % (raised for this scenario; the documented default is 82)
  • First-pass acceptance yield at release: 90 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross production ramp capacity = heat pump units per build cycle × planned ramp build cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 203 units for accepted production ramp capacity, the number this scenario is built around.
  • At this operating point the engine returns 240 units for gross production ramp capacity.
  • At this operating point the engine returns 14.4 units for production ramp availability loss.
  • At this operating point the engine returns 22.56 units for production ramp release yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected line uptime during ramp sits at 82% and the headline result is 177 units, this scenario comes in 14.63% above the baseline at 203 units.
  • A figure at this level is achievable when expected line uptime during ramp is genuinely sustained, not just peaked for a shift. It treats uptime and yield as constants, but both typically start low and climb during a ramp, so a single blended figure can hide an early shortfall.

Results at a glance

  • Accepted production ramp capacity: 203 units (headline result)
  • Gross production ramp capacity: 240 units
  • Production ramp availability loss: 14.4 units
  • Production ramp release yield loss: 22.56 units
