Trailers, Truck Bodies & Specialty Vehicles worked example

Delivery Capacity at 65% equipment uptime: a worked example in trailers, truck bodies & specialty vehicles

This worked example runs the delivery capacity numbers for a tougher week than the baseline: 65% equipment uptime instead of the typical 90%. Delivery capacity is the number of good, shippable trailers a plant can actually deliver over a planning horizon after downtime and quality losses are subtracted from the gross rated capacity.

The inputs for this scenario

  • Trailers built per production cycle: 4 units / cycle (held at the documented default)
  • Available production cycles in the horizon: 480 cycles (held at the documented default)
  • Equipment uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass yield: 97 % (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where equipment 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 S&OP, when committing to a large fleet order, or when deciding whether an uptime or yield problem is capping your ship rate. 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 output capacity: 1,211 units (headline result)
  • Gross capacity: 1,920 units
  • Uptime loss: 672 units
