Demand Ramp Planner at 99% expected line uptime during ramp: a worked example in smart home & consumer iot hardware

This scenario runs the demand 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 demand ramp planner in smart home and consumer iot hardware is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Units produced per production cycle: 4 units / cycle (unchanged)
  • Scheduled production cycles 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 on finished devices: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross demand ramp planner capacity = demand ramp planner output per cycle × available demand ramp planner cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good demand ramp planner capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross demand ramp planner capacity.
  • At this operating point the engine returns 19.2 units for demand ramp planner downtime loss.
  • At this operating point the engine returns 57.02 units for demand 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 committing volume for a product launch or ramp, sizing a build plan against a demand forecast, or negotiating capacity with a contract manufacturer. 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 demand ramp planner capacity: 1,844 units (headline result)
  • Gross demand ramp planner capacity: 1,920 units
  • Demand ramp planner downtime loss: 19.2 units
  • Demand ramp planner yield loss: 57.02 units
