Enclosure Scrap Cost at 110% scrap cost assigned to this issue: a worked example

Push scrap cost assigned to this issue up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a quality engineer needs to quantify enclosure scrap from a charger build

The inputs for this scenario

  • Scrapped charger enclosures: 18 enclosures (unchanged)
  • Cost per enclosure or enclosure set: 420 $ / enclosure (unchanged)
  • Scrap cost assigned to this issue: 110 % (raised for this scenario; the documented default is 100)
  • Disposition, replacement, or freight adders: 900 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable enclosure scrap cost = scrapped enclosures × cost per enclosure × assigned share) to the inputs above produces each figure below.
  • At this operating point the engine returns 9,216 $ for total enclosure scrap cost, the number this scenario is built around.
  • At this operating point the engine returns 512 $ / enclosure for enclosure scrap cost per scrapped enclosure.
  • At this operating point the engine returns 8,316 $ for variable enclosure scrap cost.
  • At this operating point the engine returns 900 $ for disposition, replacement, or freight adders.

How this compares with the baseline

  • Against the tool's baseline example, where scrap cost assigned to this issue sits at 100% and the headline result is 8,460 $, this scenario comes in 8.94% above the baseline at 9,216 $.
  • It computes the total cost of a charger-enclosure scrap event — the assigned share of part value plus fixed disposition, replacement, and freight adders — and the cost per scrapped enclosure. 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 enclosure scrap cost: 9,216 $ (headline result)
  • Enclosure scrap cost per scrapped enclosure: 512 $ / enclosure
  • Variable enclosure scrap cost: 8,316 $
  • Disposition, replacement, or freight adders: 900 $
