How to use this tool

  1. Enter the measured quantities and planning assumptions in the displayed units.
  2. Run the calculation, then compare the result with your available capacity or actual records.
  3. Change one assumption at a time to compare operating scenarios.

Try this example

{
  "departure": 8,
  "drive": 2.5,
  "delay": 0.5,
  "window_start": 10,
  "window_end": 12,
  "unload": 0.75
}

Accuracy and scope

Times use a common day-zero hour scale. Early arrivals wait until the window opens; negative slack means completion exceeds the window.
