Pump, Compressor & Rotating Equipment Assembly worked example

Field Failure Cost at 92% share of failures attributable to assembly: a worked example in pump, compressor & rotating equipment assembly

This scenario runs the field failure cost calculation on the strong side: 92% share of failures attributable to assembly, with every other input held at its documented default. Use it when field failure cost in pump, compressor and rotating equipment assembly is being put through a pump, compressor and rotating equipment assembly weighted-cost review.

The inputs for this scenario

  • Pump/compressor units returned from field: 100 units (unchanged)
  • Warranty repair cost per returned unit: 45 $ / unit (unchanged)
  • Share of failures attributable to assembly: 92 % (raised for this scenario; the documented default is 80)
  • Fixed dispatch and logistics cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Field Failure Cost cost = quantity × rate × capture factor + fixed cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for weighted cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for per piece value.
  • At this operating point the engine returns 4,140 $ for captured value.
  • At this operating point the engine returns 250 $ for fixed adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where share of failures attributable to assembly sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • Use it when reviewing warranty claim data, quoting the cost of quality for a pump or compressor program, or building the business case for a balance or seal-installation process improvement. 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

  • Weighted cost: 4,390 $ (headline result)
  • Per piece value: 43.9 $ / piece
  • Captured value: 4,140 $
  • Fixed adjustment: 250 $
