Cathode Active Material & Precursor Manufacturing worked example

Production Ramp Planner at 65% expected ramp uptime: a worked example in cathode active material & precursor manufacturing

This worked example runs the production ramp planner numbers for a tougher week than the baseline: 65% expected ramp uptime instead of the typical 90%. Estimate accepted CAM or precursor output during a production ramp after planned cycles, uptime, and first-pass release yield are applied.

The inputs for this scenario

  • Ramp output per production cycle: 4 kg / cycle (held at the documented default)
  • Planned ramp cycles: 480 cycles (held at the documented default)
  • Expected ramp uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass release yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross ramp production output = ramp output per production cycle × planned ramp cycles.
  • Accepted ramp production output works out to 1,211 kg at these inputs, and this is the headline figure for the scenario.
  • Gross ramp production output works out to 1,920 kg at these inputs.
  • Ramp output lost to downtime works out to 672 kg at these inputs.
  • Ramp output held or reworked works out to 37.44 kg at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected ramp uptime sits at 90% and the headline result is 1,676 kg, this scenario comes in 27.78% below the baseline at 1,211 kg.
  • Use it during ramp planning to set customer-committable volumes, or to test how an uptime or yield improvement changes releasable tonnage. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Accepted ramp production output: 1,211 kg (headline result)
  • Gross ramp production output: 1,920 kg
  • Ramp output lost to downtime: 672 kg
  • Ramp output held or reworked: 37.44 kg
