Throughput Gap with available equipment or attachment throughput of 43 units: a worked example in construction machinery & attachments

Suppose available equipment or attachment throughput falls to 43 units. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the production gap between available construction equipment output and required jobsite or shop output.

The inputs for this scenario

  • Available equipment or attachment throughput: 43 units (the input this scenario stresses; the baseline uses 86)
  • Required production throughput: 102 units (held at the documented default)
  • Throughput reference for percentage basis: 102 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Throughput shortfall or surplus = available equipment or attachment throughput - required production throughput.
  • throughput gap percentage works out to -57.84 % at these inputs, and this is the headline figure for the scenario.
  • throughput shortfall or surplus works out to -59 value at these inputs.
  • available equipment or attachment throughput works out to 43 value at these inputs.
  • required production throughput works out to 102 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where available equipment or attachment throughput sits at 86 units and the headline result is -15.69 %, this scenario comes in 269% below the baseline at -57.84 %.
  • It computes the difference between available and required throughput, then expresses that shortfall or surplus as a percentage of the required reference. 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.
