Definition: FTL f(x) is a distance based mode. Starboard will provide the road distance and drive time and you provide the cost per truck per km or mile.
How to use:
1. Go to the configuration panel (Scenario selector (upper left)>>configuration>>Transportation
2. Scroll down to the FTL f(x) line where you will be asked for a cost per mile/km
3. Enter is a cost and if you have done a regression to calculate the exponent, you may enter that also to allow for different cost/distance based on total distance.
The final formula will look like this: Cost/Truck = a * [Distance] ^ b (where a and b are the values entered below)
