Cathode Active Material & Precursor Manufacturing worked example

Production Ramp Planner at 99% expected ramp uptime: a worked example in cathode active material & precursor manufacturing

Push expected ramp uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when production ramp planner in cathode active material and precursor manufacturing is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Ramp output per production cycle: 4 kg / cycle (unchanged)
  • Planned ramp cycles: 480 cycles (unchanged)
  • Expected ramp uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected first-pass release yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross ramp production output = ramp output per production cycle × planned ramp cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 kg for accepted ramp production output, the number this scenario is built around.
  • At this operating point the engine returns 1,920 kg for gross ramp production output.
  • At this operating point the engine returns 19.2 kg for ramp output lost to downtime.
  • At this operating point the engine returns 57.02 kg for ramp output held or reworked.

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 10% above the baseline at 1,844 kg.
  • It computes gross ramp output from cycle output and cycle count, then derates it by uptime and first-pass release yield to give accepted (released) output, with explicit downtime and held/reworked losses. 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

  • Accepted ramp production output: 1,844 kg (headline result)
  • Gross ramp production output: 1,920 kg
  • Ramp output lost to downtime: 19.2 kg
  • Ramp output held or reworked: 57.02 kg
