Municipal Waste Sorting Equipment worked example

Commissioning Hours at 25% tuning, retest, and handoff allowance: a worked example in municipal waste sorting equipment

This worked example runs the commissioning hours numbers for a tougher week than the baseline: 25% tuning, retest, and handoff allowance instead of the typical 35%. Estimate the commissioning time required to bring a new sorter, baler, screen, or conveyor train up to acceptance criteria.

The inputs for this scenario

  • Commissioning checks in scope: 60 checks (held at the documented default)
  • Checks completed per engineer per minute: 0.05 checks / min (held at the documented default)
  • Tuning, retest, and handoff allowance: 25 % (the input this scenario stresses; the baseline uses 35)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base commissioning time = commissioning checks / completion rate per engineer.
  • Required commissioning time works out to 1,500 min at these inputs, and this is the headline figure for the scenario.
  • Base commissioning time works out to 1,200 min at these inputs.
  • Tuning and retest allowance applied works out to 25 % at these inputs.
  • Completion rate per engineer works out to 0.05 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where tuning, retest, and handoff allowance sits at 35% and the headline result is 1,620 min, this scenario comes in 7.41% below the baseline at 1,500 min.
  • Use it when planning the start-up window for a new or retrofitted sort line, before committing an acceptance date to the owner. 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

  • Required commissioning time: 1,500 min (headline result)
  • Base commissioning time: 1,200 min
  • Tuning and retest allowance applied: 25 %
  • Completion rate per engineer: 0.05 pieces / min
