Nonwoven Materials & Technical Textiles worked example

Production Ramp Planner at 65% expected calender and bonding line uptime: a worked example in nonwoven materials & technical textiles

This worked example runs the production ramp planner numbers for a tougher week than the baseline: 65% expected calender and bonding line uptime instead of the typical 90%. Estimate production ramp planner for nonwoven materials and technical textiles using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Web meters per spunbond line cycle: 4 units / cycle (held at the documented default)
  • Scheduled line cycles in the ramp window: 480 cycles (held at the documented default)
  • Expected calender/bonding line uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass yield after slitting and inspection: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross production ramp planner capacity = production ramp planner output per cycle × available production ramp planner cycles.
  • Good production ramp planner capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross production ramp planner capacity works out to 1,920 units at these inputs.
  • Production ramp planner downtime loss works out to 672 units at these inputs.
  • Production ramp planner yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected calender and bonding line uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • Use it during a line ramp, capacity reservation for a new order, or when validating whether current uptime and yield assumptions support a committed ship quantity. 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

  • Good production ramp planner capacity: 1,211 units (headline result)
