Definition
A per shipment value that puts a floor on the minimum cost of each shipment for that mode.
Example
An FTL lane has the following attributes:
[UNITS PER TRUCK] = 20,000 lbs / truck (set at configuration>>product>>units per truck)
[RATE PER MILE] = $2/truck/mile (from reference data)
[DISTANCE] = 100 miles (lane characteristic)
[MINIMUM SHIPMENT COST] = $250 (set at configuration>>freight>>mode)
COST PER UNIT = MAX ( [UNITS PER TRUCK] * [COST PER UNIT] , [MINIMUM SHIPMENT COST] / [UNITS PER TRUCK]
In this example the reference data is suggesting the unit cost is [2] * [100] / [20,000] or $0.002/unit and the minimum shipment supersedes that at [250] / [20,000] or $0.0025/unit.
