Ammunition Component Rework Cost Calculator at 110% share of rework actually charged to this lot: a worked example

Push share of rework actually charged to this lot up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a quality or operations team needs to estimate the cost impact of rework for a held lot

The inputs for this scenario

  • Components reworked or rework labor hours: 1,800 units or hr (unchanged)
  • Cost to rework one unit or one hour: 0.42 $ / unit or hr (unchanged)
  • Share of rework actually charged to this lot: 110 % (raised for this scenario; the documented default is 100)
  • Fixed disposition, MRB, or setup cost: 650 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable rework cost = reworked component count or hours × rework cost rate × applied rework cost share) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,482 $ rework cost for total rework cost impact, the number this scenario is built around.
  • At this operating point the engine returns 0.82 $ / piece for rework cost rate.
  • At this operating point the engine returns 832 $ for variable rework cost.
  • At this operating point the engine returns 650 $ for fixed disposition or setup cost.

How this compares with the baseline

  • Against the tool's baseline example, where share of rework actually charged to this lot sits at 100% and the headline result is 1,406 $ rework cost, this scenario comes in 5.38% above the baseline at 1,482 $ rework cost.
  • It computes total rework cost impact by combining variable rework (quantity times rate times capture share) with a fixed disposition or setup cost, and derives an effective per-piece rate. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Total rework cost impact: 1,482 $ rework cost (headline result)
  • Rework cost rate: 0.82 $ / piece
  • Variable rework cost: 832 $
  • Fixed disposition or setup cost: 650 $
