Washer Throughput at 63% expected washer uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop expected washer uptime to 63%, then walk the calculation through step by step. Estimate good cleaned part capacity per shift from washer load size, available cycles, uptime, and first-pass cleanliness yield.

The inputs for this scenario

  • Cleaned parts per washer cycle: 80 parts / cycle (held at the documented default)
  • Available washer cycles: 42 cycles (held at the documented default)
  • Expected washer uptime: 63 % (the input this scenario stresses; the baseline uses 88)
  • First-pass cleanliness yield: 96 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross washer throughput = cleaned parts per washer cycle × available washer cycles.
  • Good cleaned part throughput works out to 2,032 parts at these inputs, and this is the headline figure for the scenario.
  • Gross washer throughput works out to 3,360 parts at these inputs.
  • Washer downtime loss works out to 1,243 parts at these inputs.
  • Cleanliness yield loss works out to 84.67 parts at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected washer uptime sits at 88% and the headline result is 2,839 parts, this scenario comes in 28.41% below the baseline at 2,032 parts.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to expected washer uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes uptime and cleanliness yield are independent multipliers; in reality a washer running hot and over-cycled to recover downtime often drops first-pass yield, so the two losses can interact.

Results at a glance

  • Good cleaned part throughput: 2,032 parts (headline result)
  • Gross washer throughput: 3,360 parts
  • Washer downtime loss: 1,243 parts
  • Cleanliness yield loss: 84.67 parts
