Elevators, Escalators & Vertical Transport Equipment worked example

Throughput Per Production Line at 99% line efficiency: a worked example

Push line efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a production manager needs to compare line output with demand or shipment commitments

The inputs for this scenario

  • Completed elevator or escalator units: 32 units (unchanged)
  • Production line runtime: 40 hr (unchanged)
  • Line efficiency: 99 % (raised for this scenario; the documented default is 86)

Working through the calculation

  • Applying the documented formula (Observed line throughput = completed elevator or escalator units รท production line runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 0.79 units / hr for effective vertical transport line throughput, the number this scenario is built around.
  • At this operating point the engine returns 0.8 units / hr for observed line throughput.
  • At this operating point the engine returns 99 % for line efficiency.
  • At this operating point the engine returns 40 hr for production line runtime.

How this compares with the baseline

  • Against the tool's baseline example, where line efficiency sits at 86% and the headline result is 0.69 units / hr, this scenario comes in 15.12% above the baseline at 0.79 units / hr.
  • It computes the effective units-per-hour output of one elevator or escalator production line by dividing completed units by runtime and scaling that observed rate by line efficiency. 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 vertical transport line throughput: 0.79 units / hr (headline result)
  • Observed line throughput: 0.8 units / hr
  • Line efficiency: 99 %
  • Production line runtime: 40 hr
