Furnace Throughput Rate at 65% target throughput rate: a worked example

This worked example runs the furnace throughput rate numbers for a tougher week than the baseline: 65% target throughput rate instead of the typical 90%. Calculate furnace throughput achievement from completed loads or parts, scheduled capacity, and target throughput rate.

The inputs for this scenario

  • Completed furnace output: 42 loads (held at the documented default)
  • Scheduled furnace capacity: 48 loads (held at the documented default)
  • Target throughput rate: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Furnace throughput rate = completed furnace output ÷ scheduled furnace capacity × 100.
  • Furnace throughput rate works out to 87.5 % at these inputs, and this is the headline figure for the scenario.
  • Gap to throughput target works out to -22.5 points at these inputs.
  • Completed furnace output works out to 42 loads at these inputs.
  • Scheduled furnace capacity works out to 48 loads at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target throughput rate sits at 90% and the headline result is 87.5 %, this scenario lands almost exactly on the baseline at 87.5 %.
  • Use it per shift, day, or week to monitor furnace utilization against plan and justify capacity decisions. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Furnace throughput rate: 87.5 % (headline result)
  • Gap to throughput target: -22.5 points
  • Completed furnace output: 42 loads
  • Scheduled furnace capacity: 48 loads

Run it with your numbers

  • To rerun this with your own numbers, open the live Furnace Throughput Rate calculator, set target throughput rate to your actual value, and adjust the remaining inputs to match your operation.
