Plating, Anodizing & Surface Treatment worked example

Rack Utilization at 99% target rack utilization rate: a worked example

This scenario runs the rack utilization calculation on the strong side: 99% target rack utilization rate, with every other input held at its documented default. Use it when rack utilization in plating, anodizing and surface treatment needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Rack utilization count: 8 count (unchanged)
  • Total rack utilization population: 250 count (unchanged)
  • Target rack utilization rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Rack utilization rate = rack utilization count ÷ total rack utilization population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for rack utilization rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for rack utilization gap to target.
  • At this operating point the engine returns 8 count for rack utilization count.
  • At this operating point the engine returns 250 count for total rack utilization population.

How this compares with the baseline

  • Against the tool's baseline example, where target rack utilization rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it during capacity reviews, when deciding whether to buy more racks, or when investigating why a line cannot keep up despite owning plenty of tooling. 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

  • Rack utilization rate: 3.2 % (headline result)
  • Rack utilization gap to target: 95.8 points
  • Rack utilization count: 8 count
  • Total rack utilization population: 250 count
