Shift Output Target with net available production time of 230 min: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop net available production time to 230 min, then walk the calculation through step by step. Calculate the shift output target from available production time, target cycle time, and an expected efficiency or OEE factor.

The inputs for this scenario

  • Net available production time: 230 min (the input this scenario stresses; the baseline uses 450)
  • Target cycle time: 2 min/unit (held at the documented default)
  • Expected efficiency (OEE): 0.85 decimal (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Shift Output Target = (Available Time / Cycle Time) x Efficiency.
  • Effective output at stated efficiency works out to 0.98 units / shift at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 115 units / shift at these inputs.
  • Expected OEE / efficiency works out to 0.85 % at these inputs.
  • Net available production time works out to 2 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where net available production time sits at 450 min and the headline result is 1.91 units / shift, this scenario comes in 48.89% below the baseline at 0.98 units / shift.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to net available production time, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single representative cycle time and a flat efficiency factor — mixed product runs or changeover-heavy shifts need the available time adjusted for setup before this holds.

Results at a glance

  • Effective output at stated efficiency: 0.98 units / shift (headline result)
  • Raw throughput: 115 units / shift
  • Expected OEE / efficiency: 0.85 %
  • Net available production time: 2 hr
