Specialty Films, Membranes & Barrier Materials worked example

Production Ramp Planner at 99% expected line uptime during ramp: a worked example in specialty films, membranes & barrier materials

This scenario runs the production ramp planner calculation on the strong side: 99% expected line uptime during ramp, with every other input held at its documented default. Use it when production ramp planner in specialty films, membranes and barrier materials is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Good film output per line cycle: 4 units / cycle (unchanged)
  • Line cycles available in the ramp window: 480 cycles (unchanged)
  • Expected line uptime during ramp: 99 % (raised for this scenario; the documented default is 90)
  • Expected first-pass yield during ramp: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross production ramp planner capacity = production ramp planner output per cycle × available production ramp planner cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good production ramp planner capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross production ramp planner capacity.
  • At this operating point the engine returns 19.2 units for production ramp planner downtime loss.
  • At this operating point the engine returns 57.02 units for production ramp planner yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected line uptime during ramp sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it when planning a new product launch or line startup to commit realistic volumes and staffing before the process reaches steady state. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good production ramp planner capacity: 1,844 units (headline result)
  • Gross production ramp planner capacity: 1,920 units
  • Production ramp planner downtime loss: 19.2 units
  • Production ramp planner yield loss: 57.02 units
