Process Skids, Modular Equipment & Packaged Plants worked example

Skid Footprint at 99% bay utilization efficiency: a worked example

This scenario runs the skid footprint calculation on the strong side: 99% bay utilization efficiency, with every other input held at its documented default. Use it when skid footprint in process skids, modular equipment and packaged plants is being committed and you need a throughput number you can defend.

The inputs for this scenario

  • Skids completed and shipped this shift: 1,200 units (unchanged)
  • Assembly bay runtime: 8 hr (unchanged)
  • Bay utilization efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Raw skid footprint = completed output รท runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 149 units for effective throughput, the number this scenario is built around.
  • At this operating point the engine returns 150 units for raw throughput.
  • At this operating point the engine returns 99 % for efficiency.
  • At this operating point the engine returns 8 hr for runtime.

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 10% above the baseline at 149 units.
  • Use it when quoting lead times for a modular skid package, balancing multiple assembly bays, or checking whether a bay can absorb an added order. 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

  • Effective throughput: 149 units (headline result)
  • Raw throughput: 150 units
  • Efficiency: 99 %
  • Runtime: 8 hr
