WIP on Conveyor at 68% conveyor wip availability: a worked example

Suppose conveyor wip availability falls to 68%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good WIP carried by a conveyor from positions, turns, uptime, and usable yield.

The inputs for this scenario

  • Conveyor WIP positions: 95 positions (held at the documented default)
  • WIP turns per planning window: 6 turns (held at the documented default)
  • Conveyor WIP availability: 68 % (the input this scenario stresses; the baseline uses 94)
  • Usable WIP yield: 99 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross conveyor WIP movement = WIP positions × turns.
  • Usable WIP on conveyor works out to 384 parts at these inputs, and this is the headline figure for the scenario.
  • Gross conveyor WIP movement works out to 570 parts at these inputs.
  • WIP unavailable due to stops works out to 182 parts at these inputs.
  • WIP lost to quality or aging works out to 3.88 parts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where conveyor wip availability sits at 94% and the headline result is 530 parts, this scenario comes in 27.66% below the baseline at 384 parts.
  • It computes usable parts moving on a conveyor by multiplying available WIP positions and turns by conveyor availability and usable 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

  • Usable WIP on conveyor: 384 parts (headline result)
  • Gross conveyor WIP movement: 570 parts
  • WIP unavailable due to stops: 182 parts
  • WIP lost to quality or aging: 3.88 parts
