Conveyors worked example

Conveyor Parts Per Hour at 99% expected conveyor running efficiency: a worked example

Push expected conveyor running efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a production engineer needs to confirm whether a proposed conveyor loading pattern can feed the downstream process

The inputs for this scenario

  • Active conveyor lanes or carriers: 2 lanes (unchanged)
  • Parts delivered per lane-hour: 650 parts / lane-hr (unchanged)
  • Expected conveyor running efficiency: 99 % (raised for this scenario; the documented default is 88)

Working through the calculation

  • Applying the documented formula (Conveyor parts per hour = active lanes × parts per lane-hour × running efficiency) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,287 parts / hr for effective conveyor output, the number this scenario is built around.
  • At this operating point the engine returns 1,300 parts / hr for theoretical lane output.
  • At this operating point the engine returns 13 parts / hr for output lost to conveyor inefficiency.
  • At this operating point the engine returns 99 % for running efficiency.

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 12.5% above the baseline at 1,287 parts / hr.
  • It computes effective conveyor throughput as active lanes times per-lane rate times running efficiency, and the parts lost to that efficiency gap. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Effective conveyor output: 1,287 parts / hr (headline result)
  • Theoretical lane output: 1,300 parts / hr
  • Output lost to conveyor inefficiency: 13 parts / hr
  • Running efficiency: 99 %
