Asphalt Production Capacity Gap with capacity gap available value of 3,600 units: a worked example

Push capacity gap available value up to 3,600 units and the picture changes. This example computes every intermediate figure at that operating point. a plant manager, dispatcher, or project manager needs to know whether available mix capacity covers the paving demand

The inputs for this scenario

  • Capacity Gap available value: 3,600 units (raised for this scenario; the documented default is 1,450)
  • Capacity Gap required value: 1,320 units (unchanged)
  • Capacity Gap reference value: 1,320 units (unchanged)

Working through the calculation

  • Applying the documented formula (Capacity surplus/shortfall = available asphalt capacity - required paving tons) to the inputs above produces each figure below.
  • At this operating point the engine returns 173 % capacity margin for asphalt capacity margin, the number this scenario is built around.
  • At this operating point the engine returns 2,280 tons for capacity surplus/shortfall.
  • At this operating point the engine returns 3,600 tons for available asphalt capacity.
  • At this operating point the engine returns 1,320 tons for required paving tons.

How this compares with the baseline

  • Against the tool's baseline example, where capacity gap available value sits at 1,450 units and the headline result is 9.85 % capacity margin, this scenario comes in 1,654% above the baseline at 173 % capacity margin.
  • It computes the surplus or shortfall between available asphalt plant capacity and required paving tonnage, then divides that gap by a reference tonnage to give a percentage capacity margin. 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

  • Asphalt capacity margin: 173 % capacity margin (headline result)
  • Capacity surplus/shortfall: 2,280 tons
  • Available asphalt capacity: 3,600 tons
  • Required paving tons: 1,320 tons
