Skid Footprint at 65% bay utilization efficiency: a worked example

Suppose bay utilization efficiency falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Skid Footprint throughput measures how many process skids your modular fabrication bay actually produces per hour once real-world utilization is factored in.

The inputs for this scenario

  • Skids completed and shipped this shift: 1,200 units (held at the documented default)
  • Assembly bay runtime: 8 hr (held at the documented default)
  • Bay utilization efficiency: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw skid footprint = completed output รท runtime.
  • Effective throughput works out to 97.5 units at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 units at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where bay utilization efficiency sits at 90% and the headline result is 135 units, this scenario comes in 27.78% below the baseline at 97.5 units.
  • It divides shipped skid count by bay runtime to get raw throughput, then multiplies by utilization efficiency to give effective skids per hour. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Effective throughput: 97.5 units (headline result)
  • Raw throughput: 150 units
  • Efficiency: 65 %
  • Runtime: 8 hr
