Glass Container & Bottle Manufacturing worked example

Furnace Pull Rate at 71% target pull performance benchmark: a worked example

This worked example runs the furnace pull rate numbers for a tougher week than the baseline: 71% target pull performance benchmark instead of the typical 98%. Calculate furnace pull performance for glass bottle, jar, and container production by comparing actual packed glass tons to the planned furnace pull for the same period.

The inputs for this scenario

  • Actual furnace pull achieved: 455 tons (held at the documented default)
  • Planned furnace pull target: 475 tons (held at the documented default)
  • Target pull performance benchmark: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Furnace pull performance = actual furnace pull ÷ planned furnace pull × 100.
  • Furnace pull performance works out to 95.79 % at these inputs, and this is the headline figure for the scenario.
  • Pull performance gap to target works out to -24.79 points at these inputs.
  • Actual furnace pull works out to 455 count at these inputs.
  • Planned furnace pull works out to 475 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target pull performance benchmark sits at 98% and the headline result is 95.79 %, this scenario lands almost exactly on the baseline at 95.79 %.
  • Use it at every shift handover and in daily production reviews to confirm the furnace is hitting its scheduled tonnage and to flag drift before it compounds. 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 pull performance: 95.79 % (headline result)
