Conveyor Parts Per Hour at 63% expected conveyor running efficiency: a worked example

This worked example runs the conveyor parts per hour numbers for a tougher week than the baseline: 63% expected conveyor running efficiency instead of the typical 88%. Estimate the real part output rate from conveyor lanes, parts per pitch, and expected running efficiency.

The inputs for this scenario

  • Active conveyor lanes or carriers: 2 lanes (held at the documented default)
  • Parts delivered per lane-hour: 650 parts / lane-hr (held at the documented default)
  • Expected conveyor running efficiency: 63 % (the input this scenario stresses; the baseline uses 88)

Working through the calculation

  • The calculation starts from the formula this tool documents: Conveyor parts per hour = active lanes × parts per lane-hour × running efficiency.
  • Effective conveyor output works out to 819 parts / hr at these inputs, and this is the headline figure for the scenario.
  • Theoretical lane output works out to 1,300 parts / hr at these inputs.
  • Output lost to conveyor inefficiency works out to 481 parts / hr at these inputs.
  • Running efficiency works out to 63 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected conveyor running efficiency sits at 88% and the headline result is 1,144 parts / hr, this scenario comes in 28.41% below the baseline at 819 parts / hr.
  • Use it when sizing conveyor feed rates into downstream stations or validating whether a conveyor can sustain a required parts-per-hour demand. 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

  • Effective conveyor output: 819 parts / hr (headline result)
  • Theoretical lane output: 1,300 parts / hr
  • Output lost to conveyor inefficiency: 481 parts / hr
  • Running efficiency: 63 %
