Cold-End Inspection Capacity at 67% cold-end inspection uptime: a worked example

Suppose cold-end inspection uptime falls to 67%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate cold-end inspection capacity for glass containers using inspected containers per cycle, available inspection cycles, inspection uptime, and first-pass inspection yield.

The inputs for this scenario

  • Containers inspected per inspection cycle: 420 containers / cycle (held at the documented default)
  • Available inspection cycles: 115 cycles (held at the documented default)
  • Cold-end inspection uptime: 67 % (the input this scenario stresses; the baseline uses 93)
  • Inspection first-pass yield: 98 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross cold-end inspection capacity = containers inspected per cycle × available inspection cycles.
  • Good inspected-container capacity works out to 31,714 containers at these inputs, and this is the headline figure for the scenario.
  • Gross inspection capacity works out to 48,300 containers at these inputs.
  • Cold-end inspection uptime loss works out to 15,939 containers at these inputs.
  • Inspection yield loss works out to 647 containers at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cold-end inspection uptime sits at 93% and the headline result is 44,021 containers, this scenario comes in 27.96% below the baseline at 31,714 containers.
  • It computes good inspected-container capacity as containers per cycle times available cycles, derated by inspection uptime and inspection first-pass yield. 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

  • Good inspected-container capacity: 31,714 containers (headline result)
  • Gross inspection capacity: 48,300 containers
  • Cold-end inspection uptime loss: 15,939 containers
  • Inspection yield loss: 647 containers
